Earlier this year a structural engineer in Darwin was caught out on building design as it deemed to be considered non-compliant with the National Construction Code. The engineer was rightfully suspended of his engineering registration by the Northern Territory's Department of Infrastructure, Planning and Logistics (DPIL).

Advent of wind power as alternative energy source

The Vortex wind generator represents a radical change within the alternative energy market and conventional wind turbine design. This generator has no spinning blades (or any major moving parts at all), and appears to be a large cylindrical structure which oscillates in the wind producing energy. Instead of spinning like conventional wind turbines, its uses the principle of vorticity, which is the spinning and repeating motion of air and other fluids.

With the industry reaching new material heights, creating products which are physically beneficial to the environment, rating tools are now taking the next step towards aiming for totally sustainable and healthy development. Rating tools are now attempting to assess another crucial aspect of the ESD world, that being the social sustainability of buildings. Different from the pragmatic physical aspects of creating an environmentally sustainable development, rating tools such as Greenstar assess the social and psychological impact of buildings and how through considered design the health and wellbeing of the occupant can be taken into consideration.

Designing For Others

Architectural Interventions Improving the Environment and Biodiversity

The effect of urbanisation and urban development on the natural world has been extremely harmful. The built environment’s impact on disrupting migration patterns, habitat destruction and the general effect on the decline of biodiversity has been extremely detrimental. Therefore, through the introduction of various architectural interventions within the city, habitats can be recreated and animal colonies can be somewhat re-established improving the overall quality of our environment and promoting biodiversity which is essential to the health of the ecosystem.

Environmentally Responsive Design and Green Architecture

Sustainability and environmental performance goals are presently major contributing factors to design choices. Each new building attempts to take one step further in being even more environmentally conscious than the last. Although this process is extremely beneficial to the environment and surrounding ecosystem, where is this race to create a totally “Green building” heading? Structures are now emerging that look more like nature than building, with towering green walls and sprawling roof gardens disguising any distinguishable architectural element. This raises the question, are we going over board? Surely sustainable design does not mean a building which is literally green.

In the field of ESD, two terms which constantly appear are the U and R values of products, but what do these mean? Whether referring to insulation or glazing each product on the market has a specific either U or R value. These values refer to the thermal performance of specific products and materials and how they assist in maintaining thermal control in a building or structure. These values are an integral part of the BASIX, NatHERS and Section J process in the NCC, which require specific values to be either entered into the glazing calculator for Section J reports or specific glazing types with predetermined U and SHGC values for BASIX and NatHERS along with specific R values for insulation and building materiality.

In response to growing concerns around greenhouse emissions, the Australian Government introduced a coordinated national approach in July 2000.

This approach focused on two key directions.

First, mandatory minimum energy performance requirements were implemented through the Building Code of Australia (BCA), ensuring all new buildings meet a baseline standard.

Second, the industry was encouraged to adopt voluntary best practice initiatives, allowing for innovation and higher performance outcomes beyond compliance.

These measures were supported by theNational Framework for Energy Efficiency(NFEE), a national agreement between Australian governments aimed at improving energy efficiency across the country. The objective was clear: unlock economic value through smarter energy use, while delivering cost-effective outcomes.

To support this transition, working groups were formed across government, industry, and community sectors. Their role was to contribute to the development of the BCA Energy Efficiency Provisions.

Recognising the impact of buildings on national emissions, theAustralian Building Codes Board(ABCB) and theAustralian Greenhouse Officeformalised their collaboration through a Memorandum of Understanding.

This led to the development of the Energy Efficiency Provisions now known asSection J of the National Construction Code (NCC)— applying to both commercial and residential buildings across Australia.
