E1.02 Passive Solar Design
E1.04 Ventilation
Section Summary
Section Summary
Spaces are to be naturally well ventilate and minimise reliance on mechanical ventilation wherever possible.
Where possible, high energy e ciency standards are to be achieved through passive solar design principles and building envelope design rather than active energy generation systems.
Ventilation Considerations Checklist:
Passive Solar Design Considerations Checklist:
•
Natural cross ventilation and ceiling fans should be employed as the main form of ventilation. Provision of habitable rooms with a minimum 2.7m in floor to ceiling height to enable the inclusion of ceiling fans. Location, size and type of operation of operable windows to maximise cross ventilation to dwellings. Provision of external lockable security doors and external flywire screens to all operable windows provide for secure ventilation. The requirement for active heating and cooling is to be minimised. In all cases, energy e cient and cost-e ective methods which provide minimal running costs, should be employed. All mechanical ventilation should be exhausted externally and have self-closing dampers.
•
Maximise passive solar design benefits through orientation of living areas facing north and reductions in east and west window heat loads; Provide e ective eaves to control impact of summer sun. Green deciduous tree planting to provide screening to habitable rooms to reduce radiant heat gains in summer but facilitate solar access in winter months. Ensure natural light is maximised to reduce the reliance on artificial lighting.

E1.03 Indoor Environment Quality
•
Section Summary
E1.05 Building Envelope and Materials
Design and systems should maximise indoor air quality.
Table 11: Indoor Environment Quality Considerations Checklist Consider the following items when looking to increase indoor environment quality:
Section Summary
Building designs should take account of the embodied energy in the choice of building materials and systems. Thermal mass should be employed to maintain thermal stability during cooler months.
Indoor Air Quality
• Eliminate entry of outdoor pollutants • Provision of outdoor air
Acoustic Comfort
• Acoustic separation
Building Envelope and Materials Considerations Checklist:
Visual Comfort
• Daylight • Views to the external environment
•
All new dwellings should achieve an energy rating of at least 7 stars NatHERs rating which exceeds current regulatory requirements. High levels of bulk insulation are to be provided to wall and ceiling cavities, together with draught exclusion, to provide appropriate thermal comfort.
•
Indoor Pollutants
• VOC o -gassing: paints, adhesives, sealants and carpets. • Formaldehyde o -gassing: Engineered Wood Products. • Microbial control - Legionella impacts from cooling systems. Refer to Section D2 Mechanical for additional requirements for air conditioning.
• • •
Double glazing should be used as a minimum.
Reduce the use of materials from non-renewable sources.
incorporate durable, low embodied energy materials that will reduce the environmental impact of the development as well as lower ongoing maintenance costs. Use low volatile organic compound (VOC) paint throughout. Any flat metal roof decks should be minimised, light in colour and be sensitive to issues of reflectivity.
Thermal Comfort
• Average NatHERS Rating of 7 Stars (as per overarching requirements)
