Design & Planning Intelligence | High Performance Design
Understand how climate responsive design support helps project teams consider local climate, orientation, solar exposure, shading, natural ventilation, building form and envelope strategy before major design decisions become fixed.
Early climate responsive design can help identify opportunities, constraints and project-specific considerations before detailed modelling, compliance assessment or certification pathways are selected. The appropriate design response depends on the local climate, site conditions and project objectives, and may later be supported through more specialised assessment where appropriate.
Explore Climate Responsive DesignIn Brief
Climate responsive design support is early design guidance that considers how a building can respond to its local climate, site exposure and seasonal environmental conditions. It examines how orientation, sun path, shading, prevailing winds, ventilation potential, building form, glazing, internal planning and envelope strategy may influence the developing design. The aim is not to apply a fixed passive design checklist, but to identify project-specific opportunities, constraints and performance risks before fundamental design decisions become difficult to change.
This support may help a project team consider how winter sun, unwanted summer heat, wind exposure, humidity, surrounding buildings, topography and local microclimate should inform the design direction. The appropriate response depends on the climate zone, project type, site conditions, intended use and construction approach. Strategies that may be helpful in one Australian climate may be unsuitable in another and material performance risks should be tested through modelling where required.
Climate responsive design support does not replace a NatHERS assessment, which calculates residential thermal performance and a star rating using accredited software. It is also distinct from Passive House, which is a defined building standard with formal design, documentation and verification requirements, and from Thermal Comfort Modelling, which assesses occupied-space comfort conditions using defined metrics and modelling methods. Climate responsive design support can instead inform early decisions and identify where one of these more specific pathways may later be appropriate.
It may consider local climate, orientation, seasonal sun, shading, wind exposure, ventilation potential, building form, room planning, glazing and the developing envelope strategy.
It is most useful during concept and early design, before orientation, form, glazing, shading and envelope decisions become substantially fixed.
The review may draw on the project location, survey, site plan, floor plans, elevations, sections, surrounding context, proposed materials and the project team’s key design questions.

Understand
Climate responsive design is an approach that considers how a building may respond to the environmental conditions of its particular location. Rather than applying one standard design formula, it brings together climate, orientation, seasonal sun, shading, wind exposure, humidity, topography, surrounding development and the emerging building envelope to inform early design direction.
Climate
Temperature patterns, seasonal solar exposure, prevailing winds, humidity and periods of heat or cold can influence which design responses may be appropriate. A strategy that supports one climate may create a different outcome elsewhere, so local conditions should remain central to the review.
Site
Slope, landform, vegetation, nearby buildings, coastal exposure, street orientation and available open space can change how sun, shade and air movement reach the building. These conditions may be reviewed as performance-related inputs without replacing a broader Site & Contextual Analysis.
Building
Building orientation, massing, roof form, plan depth, room layout, glazing placement and the relationship between internal and external spaces can affect how the project receives sunlight, sheds unwanted heat and makes use of available ventilation.
Envelope
Early consideration of glazing, insulation, thermal mass, external shading, envelope continuity and air leakage awareness can help establish a coherent design direction. Detailed selections and performance outcomes may still need to be confirmed through the relevant assessment or modelling pathway.
Climate responsive design support is therefore best understood as project-specific design guidance rather than a certification system or calculation method. It may inform later pathways such as NatHERS, Passive House or more specialised environmental modelling, but it does not replace those assessments or guarantee a particular comfort, energy or compliance outcome.
Early Design
Climate responsive thinking is most useful while the design still has room to change. Decisions about orientation, building form, plan depth, glazing, shading, ventilation pathways and envelope direction are often interconnected. Reviewing them early can help the project team identify where the emerging design aligns with local climate conditions, where risks may be developing and which questions may need to be tested through a more specific assessment.
Form
Overall form can influence external exposure, solar access, shading, plan depth and the relationship between indoor and outdoor spaces. Once massing and floorplate geometry are established, later performance improvements may need to work within those earlier constraints.
Orientation
Orientation affects how different elevations receive seasonal sun and unwanted heat. Early review can help distinguish useful solar exposure from areas that may need greater control, while recognising that site shape, views, access and neighbouring development may limit idealised arrangements.
Openings
Window size, placement and external shading influence solar gain, views, daylight access and envelope performance. Considering these elements together can help avoid treating glazing as an isolated architectural feature or adding shading only after heat exposure has become apparent.
Air Movement
Room arrangement, opening locations, building depth and surrounding obstructions can affect natural ventilation potential. Early review may identify where air movement appears plausible and where noise, security, humidity, wind conditions or urban constraints could reduce its practical value.
Envelope
Early assumptions about walls, roofs, floors, glazing and continuity can establish the direction for later detailing. These decisions may need to be coordinated with the relevant Design Stage Performance Advice or project assessment pathway.
Coordination
An early climate review can help identify which questions are still qualitative and which may require quantified testing. This may support timely coordination with NatHERS, Thermal Comfort Modelling, daylight analysis or other specialist pathways where relevant.
Early climate responsive support does not remove the need for later assessment, nor does it guarantee a particular design outcome. Its value lies in helping the project team recognise climate-related relationships while fundamental decisions are still open, then coordinate further modelling or certification work where the project risk, objectives or selected pathway require it.
Climate Context
Australia contains a wide range of climate conditions, from cool temperate regions and hot dry inland areas to warm humid, tropical, coastal and high-altitude environments. Climate responsive design therefore cannot be reduced to a single national formula. The appropriate balance between solar access, shading, ventilation, insulation, thermal mass, glazing and building form depends on the location, seasonal patterns, site exposure and intended use of the project.
Cool and Temperate Conditions
In cooler and temperate regions, useful winter solar gain may support indoor comfort, but glazing and exposed surfaces can also create summer heat risk. Design review may consider solar orientation, adjustable or orientation-specific shading, envelope continuity and how internal planning distributes sunlight through the building.
Hot Dry Conditions
Hot dry climates can involve intense solar exposure and large differences between daytime and overnight temperatures. Appropriate responses may include strong external shading, controlled glazing, protected outdoor areas, insulation, carefully considered thermal mass and ventilation strategies that respond to the daily temperature cycle.
Warm Humid Conditions
In warm humid regions, preventing unwanted solar gain and supporting practical air movement may be more important than capturing heat. Building depth, opening location, shaded external spaces, roof exposure and surrounding obstructions can influence whether natural ventilation remains useful under real operating conditions.
Coastal and Exposed Sites
Coastal and elevated sites may receive useful breezes but can also experience strong winds, salt exposure, driving rain and rapidly changing conditions. Openings, external shading, balconies and outdoor rooms may need to support ventilation without making internal or external spaces difficult to use during exposed periods.
Urban Conditions
Dense urban sites can have limited solar access, obstructed wind paths, reflected heat, noise, privacy and security constraints. Climate response may therefore involve design trade-offs rather than ideal passive arrangements. Questions about neighbouring overshadowing may require a separate Solar Access & Overshadowing Analysis.
Project-Specific Conditions
Climate zone provides a useful starting point, but it does not describe every site condition. Topography, vegetation, nearby development, orientation, elevation, local wind patterns and urban heat can create a microclimate that differs from broader regional assumptions and should be interpreted in the project context.
Climate responsive principles can guide the direction of a design, but they do not demonstrate how the completed building will perform. Outcomes may be affected by geometry, construction, glazing specifications, occupancy, internal loads, ventilation operation and the interaction between multiple design decisions.
Where the project requires quantified residential thermal performance, an accredited NatHERS assessment may be appropriate. Where the design raises detailed questions about occupied conditions or environmental behaviour, Thermal Comfort Modelling, Daylight Modelling or specialist airflow analysis may be needed.
Design Factors
Climate responsive design brings several environmental and architectural factors into the same early design conversation. These factors should not be considered as isolated features. Orientation affects solar exposure, glazing affects both daylight and heat transfer, shading changes with season and elevation, and natural ventilation depends on the relationship between openings, internal planning and external conditions.
Orientation
The orientation of walls, windows and outdoor spaces affects when and how solar radiation reaches the building. Northern, eastern, western and southern elevations receive different patterns of exposure, requiring different responses rather than one shading or glazing approach applied throughout the project.
Seasonal Sun
Solar access may be beneficial during cooler periods and undesirable during warmer periods. The design challenge is often to preserve useful daylight and winter sun while limiting summer heat gain, particularly where large areas of glazing or exposed upper levels are proposed.
Shading
Eaves, awnings, fins, screens, balconies, vegetation and surrounding structures can affect solar exposure. Effective shading should respond to orientation, season and window geometry rather than relying on a standard projection depth across all elevations.
Wind
Wind direction, speed and seasonal variation can influence natural ventilation potential and external comfort. Local landform, nearby buildings and vegetation may redirect or obstruct airflow, while exposed sites may experience stronger winds than broad regional data suggests.
Ventilation
Natural ventilation depends on more than window area. Opening location, operable area, room depth, internal doors, opposing pressure zones and external obstructions can all affect how air moves through occupied spaces. Complex airflow questions may require separate CFD Modelling.
Humidity
Humidity affects how occupants experience warmth and how useful natural ventilation may be. In humid climates, increased air movement may improve perceived comfort, but ventilation alone may not manage all moisture or comfort conditions during prolonged warm and humid weather.
Building Form
Compactness, articulation, floorplate depth and roof form influence external exposure, shading, daylight penetration and ventilation pathways. A highly articulated building may create useful self-shading in some locations while increasing exposed envelope area and detailing complexity elsewhere.
Glazing
Glazing supports views, daylight and connection to the outdoors, but it can also be a significant path for heat gain and heat loss. Window area, frame type, glass performance, orientation and shading should therefore be considered together rather than selected independently.
Thermal Mass
Materials with higher thermal mass can moderate temperature change when they are located and exposed appropriately. Their usefulness depends on climate, solar access, ventilation, insulation and operating patterns. Thermal mass that receives uncontrolled summer sun may increase rather than reduce overheating risk.
Envelope
The continuity of insulation and the treatment of walls, roofs, floors, junctions and openings influence heat transfer through the building enclosure. Early envelope thinking can establish a coherent direction, while detailed performance and compliance still need to be confirmed through the relevant pathway.
Daylight
Daylight and solar heat gain are related but not identical. A space may receive useful diffuse light without direct sun, while an extensively glazed elevation may still experience glare or overheating. Detailed daylight questions may require Daylight Modelling.
Surrounding Context
Existing and future buildings, trees, landform and external surfaces may alter solar access, wind exposure and reflected heat. These relationships can inform climate design support, while broader site and planning conditions may be examined through Site & Contextual Analysis.
A climate responsive decision should rarely be judged by one factor alone. Increasing glazing may improve views and daylight but increase heat transfer. External shading may reduce summer solar gain but also affect winter sun and internal light. A compact form may reduce exposed envelope area while limiting cross ventilation or daylight penetration into deeper spaces.
Early support helps the project team recognise these relationships and identify which assumptions can remain as design guidance and which should later be quantified through Specialised ESD Design Modelling, residential rating, comfort analysis or another project-specific assessment.
Passive Design
Passive design uses the building’s orientation, form, openings, shading, materials and envelope to respond to environmental conditions before relying on active heating, cooling or lighting systems. These principles can provide a useful foundation for climate responsive design, but they should be interpreted in relation to the project rather than treated as universal rules.
Solar Access
Direct sunlight can support winter warmth and connection to seasonal conditions, but uncontrolled exposure may increase overheating and glare. The value of solar access depends on orientation, climate, room use, glazing, shading and whether heat can be managed once it enters the building.
Shading
External shading can reduce solar gain before it reaches the glazing. Its form and depth should respond to sun angle, orientation, season and window geometry. Fixed horizontal shading may suit some northern exposures, while eastern and western glazing may require different forms of control.
Natural Ventilation
Operable openings, room arrangement and building depth may support cross ventilation or buoyancy-driven airflow. The strategy should also account for noise, security, weather, humidity, external air quality and periods when occupants are unlikely to keep windows open.
Thermal Mass
Thermal mass may absorb and release heat over time, helping to moderate internal temperature swings where the climate and operating pattern support that behaviour. Its effectiveness depends on solar exposure, insulation, night-time cooling and whether the mass is meaningfully connected to the occupied space.
Insulation
Insulation can reduce heat flow through roofs, walls and floors, but overall performance depends on continuity, installation quality, junctions and the relationship with glazing and air leakage. Higher insulation levels do not resolve uncontrolled solar gain or poor window design on their own.
Glazing
Windows connect occupants with daylight, views and outside conditions, yet they can also create substantial heat gain and heat loss. Climate responsive design considers window area, orientation, frame and glass performance, operability and external shading as one coordinated system.
Building Form
Form affects exposed surface area, solar orientation, self-shading, plan depth and airflow potential. Compact forms can reduce envelope exposure, while narrower plans may improve daylight and cross ventilation. The preferred balance depends on the project and its surrounding constraints.
Daylight
Window placement, room depth, ceiling height, internal surfaces and external obstruction can influence daylight distribution. More glazing does not always create better daylight and may introduce glare or excess solar load. Detailed outcomes may require separate Daylight Modelling.
Envelope Continuity
Walls, roofs, floors, windows, doors and junctions should work as a connected enclosure. Discontinuities, complex geometry and unresolved transitions may weaken the intended performance direction even where individual materials appear suitable in isolation.
Design Principle
A design does not become climate responsive simply because it includes north-facing glazing, thermal mass, insulation or operable windows. Each feature should have a clear role within the local climate and should be coordinated with the other parts of the building. A strategy that performs well in one orientation, season or climate may create a risk under different conditions.
Climate responsive design support can help establish this early relationship between climate and architecture. It remains distinct from Passive House, which is a defined performance and certification framework, and from NatHERS, which uses accredited software to calculate residential thermal performance. Where design questions need quantified comparison, they may be examined through Specialised ESD Design Modelling or another appropriate assessment pathway.
Design Interpretation
Climate responsive design involves more than identifying favourable environmental conditions. It also requires understanding where a seemingly beneficial design decision may create a different performance risk. Sunlight can support winter warmth but contribute to summer overheating. Openings can improve ventilation but also introduce noise, weather exposure or uncontrolled air movement. The design response therefore depends on how each opportunity interacts with the climate, site, building form and intended operation of the project.
Solar Exposure
Opportunity: Well-positioned glazing may allow useful winter sun into occupied spaces and support seasonal warmth, daylight and connection to outdoor conditions.
Risk: The same glazing may admit excessive heat during warmer periods where orientation, glass selection or external shading does not adequately control exposure.
Natural Ventilation
Opportunity: Operable openings and clear airflow paths may support natural cooling and reduce reliance on mechanical systems during suitable conditions.
Risk: External noise, humidity, strong winds, smoke, security concerns or internal planning may prevent occupants from using those openings as intended.
Thermal Mass
Opportunity: Appropriately located thermal mass may absorb heat and help moderate internal temperature changes across the day.
Risk: Mass exposed to uncontrolled summer sun or insufficient night cooling may retain unwanted heat and delay recovery during prolonged hot conditions.
Glazing
Opportunity: Larger windows may improve daylight, views, visual connection and the perceived openness of internal spaces.
Risk: Extensive glazing can increase heat gain, heat loss, glare and dependence on blinds where its size, orientation and specification are not coordinated with shading and envelope performance.
Compact Form
Opportunity: A compact building form may reduce the amount of exposed envelope relative to the enclosed floor area and simplify enclosure continuity.
Risk: Deeper internal spaces may receive less daylight and have fewer opportunities for cross ventilation, particularly in multi-residential or dense urban projects.
External Shading
Opportunity: Well-designed shading may substantially reduce direct summer solar gain before it reaches the glass.
Risk: Oversized or poorly oriented shading may restrict winter sun, reduce daylight or affect views without providing effective control during the periods of greatest exposure.
Insulation and Airtightness
Opportunity: A more continuous enclosure may reduce unwanted heat transfer and uncontrolled air leakage, supporting more stable internal conditions.
Risk: Improved enclosure performance must be coordinated with ventilation, moisture management and services. Envelope measures should not be treated as isolated material upgrades.
Vegetation and Context
Opportunity: Existing trees, landscape and surrounding structures may provide useful shade, wind protection and moderated external conditions.
Risk: Vegetation may be seasonal, removed or altered, while neighbouring development may change future solar access or wind conditions. Broader context questions may require Site & Contextual Analysis.
Project-Specific Interpretation
The performance value of a design feature depends on where it is located, how it is detailed, when it is expected to operate and how it interacts with the rest of the building. North-facing glazing, thermal mass, operable windows, deep eaves or a compact floorplate may each support climate response in the right circumstances, but none demonstrates performance on its own.
Climate responsive design support can help identify these competing effects while the project is still developing. Where the balance between opportunities and risks cannot be resolved qualitatively, the design may need to be compared through Specialised ESD Design Modelling, Thermal Comfort Modelling, Daylight Modelling or another relevant assessment pathway.
Assessment Boundaries
Climate responsive design support is an early design guidance service. It helps the project team interpret climate, site exposure and architectural decisions before a formal rating, certification pathway or detailed simulation is undertaken. Related assessments may address some of the same building elements, but they answer different questions and produce different forms of evidence.
Climate Responsive Design Support
This service considers how the emerging architecture may respond to local climate, orientation, solar exposure, wind, shading, glazing, ventilation and envelope strategy.
It is generally most useful during concept or early design development, when the form, planning and façade remain open to meaningful change. It provides design guidance rather than a certificate, rating or verified performance result.
NatHERS
NatHERS uses accredited software to calculate the predicted heating and cooling loads of a residential design and express its thermal performance through a star rating.
It is a formal residential assessment pathway. Climate responsive design support may help improve the design before or during a NatHERS assessment, but it does not replace the accredited rating or associated compliance documentation.
Passive House
Passive House is a defined building performance framework with specific criteria relating to energy demand, airtightness, thermal bridging, comfort and other project outcomes.
Climate responsive design may support some of the same architectural decisions, but it is not a substitute for Passive House modelling, detailing, verification or certification.
Thermal Comfort Modelling
Thermal Comfort Modelling examines internal environmental conditions using defined assumptions about weather, occupancy, construction, glazing, ventilation and building operation.
It may quantify temperatures, comfort conditions or overheating risk in greater detail. Climate responsive design support can identify the questions that require testing, but it does not itself demonstrate hourly comfort performance.
Daylight Modelling
Daylight Modelling investigates daylight availability and distribution using project geometry, glazing, surrounding obstructions and defined performance metrics.
Climate responsive design support may recommend changes to window location, room depth, shading or massing, but detailed daylight outcomes require a dedicated assessment where quantified evidence is needed.
CFD Modelling
CFD Modelling can examine airflow, pressure and velocity patterns where natural ventilation or wind behaviour is too complex to assess through general design principles alone.
Climate responsive support may identify likely airflow opportunities and obstructions, while CFD provides a more detailed numerical investigation of selected scenarios.
Solar Access Assessment
Solar Access & Overshadowing Analysis focuses on solar access relationships within the proposal and between the development, neighbouring properties and relevant outdoor areas.
Climate responsive design support may use solar access as one design consideration, but it does not replace planning evidence or project-specific overshadowing analysis.
Site & Contextual Analysis
Site & Contextual Analysis considers the broader physical and planning context, including landform, neighbouring development, landscape, access, exposure and surrounding spatial relationships.
Climate responsive design support has a narrower environmental design focus. It may draw on site context, but its primary question is how the architecture should respond to climate rather than how the full site context should inform planning and development decisions.
Choosing the Right Pathway
A project may use climate responsive design support at the beginning and one or more formal assessments later. The early review helps establish a coherent design direction. Subsequent modelling can test selected decisions, while an accredited rating or certification process provides the evidence required by the relevant framework.
The appropriate pathway depends on the building type, project stage, design question and required outcome. Where several environmental questions overlap, Design Stage Performance Advice or Specialised ESD Design Modelling may help coordinate the next level of investigation without confusing early guidance with verified performance.
Further Investigation
Climate responsive design support can identify likely opportunities, constraints and areas of performance risk while the architecture is still developing. Some questions, however, cannot be resolved reliably through qualitative review alone. Further analysis may be appropriate where the outcome depends on detailed geometry, hourly weather conditions, construction specifications, occupancy, building operation or the interaction between several design variables.
Competing Design Options
Further analysis may be useful where two or more design options have different advantages and risks. Alternative glazing ratios, shading depths, orientations, envelope specifications or floorplate arrangements may need to be compared using consistent assumptions rather than judged from isolated features.
Overheating Risk
Large areas of glazing, strong western exposure, limited night cooling, high internal loads or lightweight construction may create overheating concerns. Thermal Comfort Modelling may be used to examine how internal conditions could change over time under defined operating scenarios.
Daylight and Glare
Window size and location may influence daylight, views, solar gain, glare and heat transfer at the same time. Where the project requires quantified evidence of daylight availability or the comparison of façade options, Daylight Modelling may be appropriate.
Complex Airflow
Natural ventilation may be difficult to predict in deep plans, tall buildings, sheltered courtyards, densely developed sites or projects with complicated opening arrangements. Where airflow direction, velocity or pressure requires closer investigation, CFD Modelling may provide a more detailed assessment.
Neighbouring Development
The performance of a design may depend on existing or proposed buildings that affect sunlight, shade or exposure. Where planning evidence or detailed comparison is required, a separate Solar Access & Overshadowing Analysis may be needed.
Residential Rating
For applicable residential projects, climate responsive design advice does not replace the formal calculation of thermal performance. An accredited NatHERS assessment may be required to determine the star rating and support the relevant compliance pathway.
Defined Performance Target
Projects pursuing a defined performance framework need to be assessed against that framework’s own criteria. Climate responsive design may help establish a suitable architectural direction, but a project targeting Passive House still requires dedicated modelling, detailing and verification.
Integrated Performance
Some projects require coordinated investigation of thermal conditions, daylight, ventilation, façade design and building operation. In these cases, Specialised ESD Design Modelling may help structure the analysis around the project’s specific design questions.
Escalating the Review
Additional modelling is most useful when the project team understands what needs to be tested and which decisions may change in response to the result. A broad request to model the building can produce information without resolving the design issue. A focused question, such as whether revised shading reduces overheating without materially reducing daylight, creates a clearer basis for comparison.
Climate responsive design support can help identify those questions before the project enters a more detailed assessment stage. Where a wider performance strategy is needed, Design Stage Performance Advice may help coordinate the sequence of reviews, modelling and formal assessment.
Project Application
Climate responsive design support may be useful when the project team needs early environmental guidance before the design becomes difficult or costly to change. It is particularly relevant where climate, orientation, solar exposure, wind, glazing, shading or envelope decisions are already influencing the architecture, but the appropriate response has not yet been established.
Concept Design
Early support may help shape building orientation, massing, plan depth, zoning, opening locations, roof form and external shading while the design team still has the flexibility to test meaningful alternatives.
Design Development
The service may also be useful during design development where the overall form is established but glazing, shading, materials, insulation, ventilation paths or façade arrangements are still being coordinated.
Constrained Sites
Urban density, narrow allotments, steep land, existing buildings, protected views or planning controls may prevent an ideal passive arrangement. Climate responsive support can help identify a practical response within those constraints rather than applying generic orientation rules.
Unfamiliar Climate
A project team may benefit from support when designing in a climate, region or microclimate that differs from its usual experience. The review can help interpret local solar, wind, humidity and seasonal conditions before familiar design assumptions are carried into an unsuitable setting.
Glazing and Façade Decisions
Large windows, extensive façades and view-driven design may create competing requirements for daylight, solar control, heat transfer, privacy and external shading. Early review can help the project team understand these trade-offs before specifications are selected.
Natural Ventilation Strategy
Projects seeking to use natural ventilation may benefit from an early review of opening locations, plan depth, internal pathways, external obstructions and likely operating constraints. More complex airflow questions may later require CFD Modelling.
Performance Ambition
Climate responsive design support may assist projects seeking stronger environmental outcomes before choosing a formal rating, modelling or certification pathway. It can help clarify whether the next step should involve NatHERS, Passive House or another assessment.
Design Review
A review may be useful where the design has already developed but concerns remain about summer exposure, poor solar orientation, limited ventilation, excessive glazing or unresolved envelope decisions. The value of the review will depend on whether the project can still respond to the findings.
Multi-Disciplinary Coordination
Climate decisions may affect architectural form, façade design, structural systems, services, landscape and planning outcomes. Early guidance can create a common environmental direction before separate disciplines advance assumptions that are difficult to reconcile later.
Timing
Climate responsive design support is most effective when the project team can still act on the findings. Changes to orientation, massing, room arrangement and façade composition become progressively harder to make once planning approval, structural coordination, consultant documentation and procurement have advanced.
Later review may still help refine shading, glazing, insulation and ventilation strategies, but it should not be expected to recover every opportunity that was lost during concept design. For projects requiring broader coordination across environmental objectives, Design Stage Performance Advice may provide a wider pathway for ongoing support.
Review Inputs
The information reviewed will depend on the project stage and the design questions being considered. Early concept advice may begin with limited architectural information, while a more developed review may consider detailed plans, elevations, façade studies, construction assumptions and relevant site material. The purpose is to understand the emerging design well enough to identify meaningful climate opportunities, constraints and performance risks.
Site Location
The project address or site location helps establish the broad climate context, including seasonal temperature patterns, solar conditions, wind exposure, humidity and other regional influences relevant to the design response.
Site Plan
A site plan may show true north, boundaries, setbacks, neighbouring development, existing structures, landscape, access and the proposed building position. These relationships can influence solar access, shading, wind exposure and the practical orientation of the project.
Floor Plans
Floor plans help identify the relationship between room use, orientation, internal zoning, circulation, opening positions and building depth. They may also show whether occupied spaces have practical opportunities for daylight, solar access or cross ventilation.
Elevations and Sections
Elevations and sections may reveal glazing proportions, ceiling heights, roof form, eaves, balconies, screens and other external features that influence solar exposure, shading, daylight penetration, ventilation and envelope continuity.
Massing Studies
Concept models, perspective views or massing studies may help explain the overall form, floorplate depth, articulation and relationship between building volumes. This can be particularly useful where the geometry creates self-shading, sheltered external spaces or complex exposure.
Glazing Information
Where available, window schedules, indicative glass specifications, frame assumptions and operability may be reviewed. At an early stage, the assessment may instead consider broad glazing proportions and orientation before products are selected.
Envelope Assumptions
Indicative wall, roof, floor and insulation strategies may help establish how the building enclosure is expected to respond to external conditions. The review may identify areas requiring coordination without providing detailed construction certification or compliance evidence.
Landscape Information
Existing and proposed vegetation may affect shade, wind, privacy and the usability of external spaces. Landscape information may also indicate whether trees or planted elements are being relied on as part of the climate response and how seasonal or future change could affect that strategy.
Project Objectives
The review is more useful when the project team identifies its priorities, such as reducing summer heat, preserving winter sun, supporting natural ventilation, improving daylight or establishing an envelope direction. These priorities help distinguish essential outcomes from secondary preferences.
Known Constraints
Planning controls, heritage requirements, view priorities, structural systems, construction methods, budget and client preferences may limit the available response. Identifying these constraints early helps keep recommendations relevant and capable of being incorporated into the design.
Previous Assessments
Existing reports, preliminary ratings or consultant advice may be reviewed where they help explain the design direction or identify unresolved issues. This may include prior NatHERS results, solar studies or early environmental modelling.
Contextual Material
Photographs, survey information, nearby building heights or other contextual material may help explain obstructions, exposure and local conditions. Where the wider physical setting requires a more detailed review, a separate Site & Contextual Analysis may be appropriate.
Information Quality
Climate responsive design support does not always require a fully documented project. Sketch plans, preliminary massing and clear design objectives may be sufficient for an early strategic review. At this stage, the advice will generally focus on broad design direction rather than detailed material or product decisions.
As the design develops, updated information may be required to confirm whether the earlier direction remains suitable. Where specific performance outcomes need to be measured rather than interpreted, the project may progress to Specialised ESD Design Modelling, Thermal Comfort Modelling or another defined assessment pathway.
Review Process
The review process is shaped around the project stage, available documentation and the environmental design questions that need to be resolved. An early concept review may focus on broad architectural direction, while a later review may examine glazing, shading, envelope and ventilation decisions in greater detail. The process is intended to support design development rather than create a separate layer of analysis disconnected from the project team.
Step 01
The review begins by identifying the decision the project team is trying to make. This may involve orientation, summer exposure, glazing, shading, ventilation, envelope direction or the relationship between several competing design priorities.
Step 02
Certified Energy reviews the available drawings, site information, design objectives, known constraints and any relevant previous assessments. The level of detail considered will reflect the maturity of the design and the scope of the requested advice.
Step 03
The project is considered in relation to local climate, orientation, seasonal sun, wind, humidity, exposure, landform and surrounding development. Where broader physical constraints need separate investigation, Site & Contextual Analysis may be appropriate.
Step 04
The review identifies where the design may benefit from solar access, shading, natural ventilation, thermal mass, daylight or envelope control. It also highlights conditions that may create overheating, heat loss, glare, poor airflow or operational dependence.
Step 05
Recommendations are developed in response to the actual design rather than applied as a generic checklist. Advice may relate to massing, room arrangement, opening location, façade treatment, shading, glazing proportions, material direction or envelope continuity.
Step 06
Where appropriate, findings may be discussed with the architect, designer or project team so that recommendations can be understood in relation to planning, structure, services, cost, appearance and other project requirements.
Step 07
The review may identify questions that cannot be resolved through qualitative guidance alone. These may include overheating, daylight, airflow or alternative façade scenarios that require Specialised ESD Design Modelling.
Step 08
The findings can inform the next architectural revision, consultant coordination or formal assessment stage. Depending on the project, this may lead into NatHERS, Thermal Comfort Modelling or another defined pathway.
Collaborative Review
Climate responsive advice is most useful when it reaches the people making the architectural decisions and is provided at a stage when those decisions can still change. A recommendation may need to be balanced against planning controls, views, structure, services, cost and the intended character of the project.
For this reason, the process may involve review, discussion and refinement rather than a single isolated report. Projects requiring broader ongoing environmental coordination may be better supported through Design Stage Performance Advice, while this service remains focused on the climate response of the emerging design.
Review Outputs
The form of the deliverable will depend on the project stage, the questions being reviewed and the level of documentation available. Some projects may require a concise strategic review, while others may benefit from marked-up drawings, design option commentary or recommendations that can be carried into the next architectural revision. The deliverable is intended to communicate practical design guidance rather than provide a formal rating, certificate or verified simulation result.
Strategic Review
A written summary may explain the principal climate conditions affecting the project, the strengths and weaknesses of the current design direction and the most important opportunities for improvement.
Drawing Review
Plans, elevations or sections may be annotated to identify solar exposure, ventilation paths, shading issues, glazing concerns, envelope discontinuities or other design matters requiring attention.
Design Recommendations
Recommendations may address orientation, room arrangement, building depth, opening locations, external shading, glazing proportions, insulation direction, thermal mass or natural ventilation strategy.
Option Review
Where the team is considering alternative massing, façade, glazing or shading approaches, the review may compare the likely advantages, limitations and climate implications of each option.

The deliverable may identify priority risks such as overheating, excessive western exposure, limited cross ventilation, deep internal spaces, poor winter solar access or reliance on unresolved façade assumptions.
Priority Actions
The review may distinguish between high-priority design changes, matters requiring coordination and lower-priority refinements. This can help the project team focus on decisions with the greatest potential influence on performance.
Consultant Coordination
Where the review involves a meeting or design workshop, the output may include a record of the principal issues discussed, agreed design directions and matters requiring follow-up by the relevant consultant or discipline.
Further Assessment
The review may identify questions requiring dedicated analysis, such as overheating, daylight, airflow or formal residential thermal performance. These may lead to Thermal Comfort Modelling, Daylight Modelling, CFD Modelling or NatHERS.
Updated Review
Where included in the agreed scope, revised drawings may be reviewed to determine whether the principal recommendations have been incorporated and whether the changes have introduced new climate or performance considerations.
Scope Clarity
Not every review will include every output listed above. A concept-stage commission may focus on strategic direction and priority actions, while a more developed project may require detailed drawing comments or comparison of specific façade and envelope options. The proposed deliverable should therefore be agreed before the review begins.
Climate responsive design support does not provide a performance guarantee or replace the evidence required by a formal assessment framework. Where the project needs measured, calculated or certified outcomes, the review can help define the next stage of Specialised ESD Design Modelling or another relevant assessment pathway.
Common Misunderstandings
Many climate responsive design problems do not arise because good principles are unknown. They occur because a single design idea is applied without considering the wider architectural context. Climate responsive design is rarely about one feature in isolation. The interaction between orientation, glazing, shading, ventilation, materials, planning and site conditions usually determines whether a building performs as intended.
Orientation
Good orientation is valuable, but it cannot compensate for poor glazing design, ineffective shading, inadequate insulation or an unsuitable building form. Orientation works as part of a coordinated environmental strategy rather than as a standalone solution.
Glazing
Large glazed areas may improve views and daylight, but they can also increase heat gain, heat loss and glare. Window design should always respond to orientation, climate, shading and intended use of the adjoining spaces.
Shading
Different elevations experience very different solar conditions. Effective shading generally responds to orientation, seasonal sun angles and building use rather than repeating identical details around the entire building.
Ventilation
Natural ventilation depends on airflow paths, pressure differences, opening positions, internal planning and external wind conditions. Simply adding more windows does not necessarily improve ventilation performance.
Thermal Mass
Thermal mass performs best when it is appropriately exposed, protected from unwanted summer heat and able to release stored heat when required. Without these conditions it may contribute to overheating rather than comfort.
Envelope
Insulation is an important part of environmental performance, but it cannot replace good solar design, ventilation, shading or envelope continuity. Effective buildings rely on several coordinated passive strategies working together.
Climate
Design responses that work well in a cool temperate climate may not be appropriate in tropical, arid or coastal conditions. Climate responsive architecture should always reflect local environmental conditions rather than repeat a universal solution.
Process
Many environmental opportunities are established during concept design. Once the building form, planning and façade are fixed, the available improvements often become smaller, more expensive or technically constrained.
Assessment
Climate responsive design support provides informed architectural guidance. It does not replace quantified assessment, simulation or certification where a project requires evidence through NatHERS, Thermal Comfort Modelling or other specialist services.
Good Practice
Well-performing buildings rarely depend on one exceptional feature. Instead, they achieve better outcomes through a balanced combination of orientation, passive solar design, shading, daylight, ventilation, envelope quality and thoughtful architectural planning. Each decision reinforces the others rather than competing with them.
Climate responsive design support aims to identify that balance before major decisions become fixed. Where further testing is needed, the project can then progress to the most appropriate modelling or assessment pathway with a stronger architectural foundation.
Frequently Asked Questions
Climate responsive design is an architectural approach that responds to the environmental conditions of a particular location.
Rather than applying a standard solution, it considers orientation, solar access, shading, wind, ventilation, daylight, building form, materials and local climate conditions to help support more comfortable and environmentally appropriate buildings.
Climate Responsive Design Support is an early design guidance service that reviews how an emerging building design responds to its climate, site exposure and environmental conditions.
The review may identify opportunities, constraints and design risks relating to orientation, solar exposure, shading, glazing, ventilation, building form, thermal mass and the building envelope.
No. Passive design forms an important part of climate responsive design, but climate responsive design is broader.
It also considers the specific climate, site constraints, surrounding development and the way multiple passive strategies interact within an individual architectural proposal.
No. Climate responsive design is a general architectural approach that responds to local environmental conditions.
Passive House is a defined building performance framework with specific criteria relating to energy demand, airtightness, thermal bridging, comfort and verification.
No. Climate Responsive Design Support provides early design guidance and does not calculate a residential thermal performance rating.
An accredited NatHERS assessment may still be required to determine the project’s star rating and support the relevant residential compliance pathway.
Climate responsive design is generally most useful during feasibility, concept design or early design development.
At these stages, orientation, massing, room planning, glazing, shading and façade decisions may still be adjusted before planning, structural coordination and detailed documentation make substantial changes more difficult.
Climate responsive design can help guide architectural decisions that influence thermal comfort, including orientation, external shading, glazing, natural ventilation, thermal mass and envelope performance.
Where predicted internal temperatures, overheating hours or quantified comfort outcomes are required, a separate Thermal Comfort Modelling assessment may be appropriate.
Yes. Existing buildings may benefit where renovations, extensions or façade upgrades create an opportunity to reconsider solar control, natural ventilation, daylight, glazing or envelope performance.
The available improvements will depend on the existing building, the extent of the proposed works and which architectural elements can practically be changed.
No. Many early design questions can be explored through architectural review, climate interpretation and established environmental design principles.
Where the outcome depends on detailed geometry, hourly weather conditions, occupancy or complex interactions between design variables, additional modelling may be recommended.
Useful information may include the project location, site plan, concept drawings, floor plans, elevations, sections, massing studies, glazing assumptions and relevant landscape information.
Project objectives, known constraints and any previous environmental assessments may also be reviewed. The information required depends on the project stage and the design questions being considered.
Yes. The review may consider glazing area, orientation, opening location, external shading, façade articulation and broad envelope assumptions.
It may identify likely design risks or opportunities, but it does not replace detailed façade engineering, product specification, compliance assessment or quantified performance modelling.
The review may consider likely ventilation opportunities based on opening locations, plan depth, internal airflow paths, prevailing conditions and surrounding obstructions.
Where airflow direction, velocity, pressure or complex interactions need to be quantified, a separate CFD Modelling assessment may be required.
Yes. Climate responsive design guidance may consider room depth, window location, glazing proportions, external obstructions and the relationship between daylight and solar exposure.
Where quantified daylight availability, distribution or comparison of façade options is required, a separate Daylight Modelling
The review may identify questions that cannot be resolved reliably through qualitative design guidance alone.
Depending on the project, Certified Energy may recommend Thermal Comfort Modelling, Daylight Modelling, CFD Modelling, Solar Access & Overshadowing Analysis or another project-specific assessment.
No. Climate Responsive Design Support provides project-specific guidance based on the available design information and agreed review scope.
It does not provide a performance guarantee, formal rating, compliance certificate or verified simulation result. These outcomes require the relevant assessment, modelling or certification pathway.
Yes. Where orientation, massing, room arrangement, glazing, shading or envelope assumptions change, the earlier findings may need to be reconsidered.
Whether an updated review is required depends on the significance of the changes and whether they affect the climate relationships originally assessed.
Project Specific Requirements
The appropriate review scope, required information, design questions and possible deliverables depend on the building type, climate, project stage, available documentation and intended performance pathway. These answers provide general guidance and should not be treated as a formal rating, performance guarantee, compliance assessment or substitute for project-specific modelling, certification or specialist advice.
