To prescribe the operation profiles for air-conditioning, artificial lighting, and equipment and appliances that may be used to model the proposed and reference building.

This specification sets out standard operation profiles for calculating the annual energy consumption, and hence annual greenhouse gas emissions, of a proposed and reference building. It provides various options in Table S35C2n to account for heat gains per person and where applicable, heat gains from meals. The number of people must be calculated in accordance with D2D18.

Although the values stated may not be those actually achieved in some buildings, the values are derived from industry accepted data sources and are considered the most typical. The same rates apply for the proposed building and reference building under J1V2 and J1V3.

They do not have to be used as part of the Verification Methods provided the operating hours of the building per year used in the calculation are not less than 2,500 hours. The profiles in the NABERS Energy and Green Star simulation requirements can also be used (see S34C3(6)(g)).
