Code Readiness Multifamily Air-sealing Research: MF Air-sealing Modeling Report

Project Number CR21PGE1901 Organization PG&E End-use Other Sector Residential Project Year(s) 2021 - 2023

This report summarizes building energy modeling analysis completed over a period of time from 2022 through 2023 as part of PG&E’s Code Readiness program effort to better understand air-leakage rates in recently constructed multifamily buildings in California. The building energy modeling in this report focuses on analyzing effects of sealing interior and exterior surfaces in multifamily buildings to decrease air leakage, thereby impacting annual site energy, Time Dependent Valuation (TDV) energy consumption, and to a lesser degree Lifetime Systemwide Cost (LSC).
