To re-cap what I discussed last November, the below matrix summarises current and upcoming regulations from May 2011.
Energy Efficiency Requirements for Apartments for Classes 2 and 4
Comments and application for insulation
Current Regulations BCA 2009 Section J0.2
From May 2011 Regulations BCA 2010 Section J0.2
Is Section J required for multi-level apartments?
Short answer is Yes. Multi-level apartment buildings are considered as class 2 type. A brief Section J energy assessment will be required for the common areas and basement carparks (Class 7a). If the proposed building has either retail (Class 6) or commercial offices (Class 5), then these areas will require a full Section J energy assessment to include: fabric, glazing and services such as airconditioning and artificial lighting.
To satisfy ESD requirements, energy efficient electrical appliances and efficient water fixtures to be within one point of the highest efficiency available on the market. This is to apply for items which are part of the base building works.
