Indoor Environment quality

By rewarding both energy efficiency and encouraging occupant well-being, the Green Star rating system promotes and rewards a holistic approach to sustainability that results in multiple benefits. Such benefits would include: Reductions to occupant stress, Improvements to air quality through appropriate ventilation, the provision of high levels of thermal, visual and acoustic comfort and also reduced exposure to pollutants.

One (1) point is awarded where project teams demonstrate that the ventilation system meets all of the following conditions:

  • The entry of outdoor air pollutants is mitigated, in accordance with 9.1.1;

  • The system is designed for ease of maintenance and cleaning, in accordance with 9.1.2; and

  • The system has been cleaned prior to occupation and use, in accordance with 9.1.3.

9.1.1 Entry of Outdoor Pollutants

The entry of outdoor air pollutants to the space must be minimised. The building ventilation systems must be designed to comply with ASHRAE Standard 62.1:2013 in regards to minimum separation distances between pollution sources and outdoor air intakes. Windows, doors, openings, vents, grilles, and skylights are all considered outdoor air intakes for purposes of this credit and must be modelled taking into account their free area.

Compliance is to be demonstrated in accordance with the distances specified in Table 5.5.1 of the Standard, however projects must also ensure compliance with any other requirement or guidance nominated within the Standard. Analytical solutions are also acceptable by following the example provided within Appendix F of ASHRAE Standard 62.1.

9.1.2 Design for Ease of Maintenance and Cleaning

Any mechanical ventilation system within the building, whether existing or new, must be designed to provide adequate access for maintenance, to both sides of all moisture and debris-catching components, within the air distribution system. Moisture-producing and debris-catching components include items such as cooling coils, heating coils, fan coil units, humidifiers and filters in the air handling system.

Where components do not have access for maintenance from both sides due to the size of the unit, project teams are encouraged to submit a technical question to the GBCA outlining how maintenance and cleaning processes of the air distribution systems components are achieved in line with the intent of the criterion.

There are two methods for demonstrating than an engineered wood product complies:

  1. Product Certification in accordance with 13.2A; or

  2. Laboratory Testing in accordance with 13.2B.

A combination of methods can be used to demonstrate compliance.

Engineered wood products include particleboard, plywood, Medium Density Fibreboard (MDF), Laminated Veneer Lumber (LVL), High-Pressure Laminate (HPL), Compact Laminate and decorative overlaid wood panels. Timber veneers are excluded. Where only part of a product is composed of an engineered wood product, the limits apply only to that portion of the product, not the entire item.

The following applications of engineered wood products are excluded from this credit:

  • Formwork;

  • Car park applications; and

  • Non-engineered wood products such as milled timber.

13.2A Product Certification

The product is certified under a recognised Product Certification Scheme. The current list of recognised schemes is shown on the GBCA website http://new.gbca.org.au/product-certification- schemes/.

The certificate must be current at the time of product purchase. R3.13.01 and list the relevant product name and model.
