(Source: JDSUPRA) On May 9, 2018, the California Energy Commission adopted revisions to the State’s Building Energy Efficiency Standards (“2019 Standards”). There are two basic options for compliance: (1) demonstrating compliance with performance standards, which require a building to meet specified energy budgets while providing flexibility in selecting the features to meet those energy budgets (“performance approach”); and (2) installing a set of prescriptive measures, which offers simplicity but less flexibility (“prescriptive approach”). Notably, the 2019 Standards modify the prescriptive approach by adding the requirement that, with certain exceptions, all new single-family and low-rise multi-family (three or fewer habitable stories) buildings, must be constructed with solar photovoltaic (PV) systems. In addition, this new PV prescriptive requirement will set the standard “design budget” for the performance compliance method. Read full article…
