## 1.4 Compliance for Newly Constructed Buildings

Compliance for newly constructed buildings requires calculating the proposed design energy use, the standard design energy budget, and the reference design energy use. There may also be additional internal calculations to establish the standard design PV requirement and the proposed design PV scaling when a target energy design rating (EDR) is specified.

The energy use for the standard, proposed and reference designs are combined into two dimensionless EDRs—one EDR for efficiency and one for total energy. Compliance requires meeting two criteria:

1. Proposed efficiency EDR must be equal or less than standard efficiency EDR.

2. Total EDR (efficiency, PV, battery storage) must be equal or less than total standard EDR.

Before combining into EDR values, the energy use is expressed in kTDV/ft2. For efficiency calculations, the energy use includes space heating, space cooling, ventilation, and water heating. Efficiency can include a portion of the battery storage energy savings when the self-utilization credit is specified. Total energy calculations include the efficiency end uses plus interior lighting, appliances, cooking, plug loads, and exterior lighting. The total energy may include PV generation and flexibility measures, if specified.
