Compliance for newly constructed buildings requires calculating the proposed design energy use, the standard design energy use, and the reference design energy use. There may also be additional internal calculations to establish the standard design photovoltaics (PV) requirement and the proposed design PV scaling when target energy design ratings (EDR) are specified. There are two EDRs that are considered in the energy budget that are described in more detail in in this chapter and Section 1.5 Energy Design Rating.

The proposed building shall separately comply with the source energy design rating (EDR1), efficiency energy design rating (Efficiency EDR2), and total energy design rating (Total EDR2). No tradeoffs are allowed between EDR1 and EDR2.

Compliance with EDR2 requires meeting two criteria. First, the proposed design Efficiency EDR2 must be equal to or less than the standard design Efficiency EDR2. Second, the proposed design Total EDR2 must be equal to or less than the standard design Total EDR2.
