This report summarizes technical analysis conducted by Pacific Northwest National Laboratory (PNNL), assessing expected end-use energy consumption in commercial buildings, based on recent editions of the model energy code for the commercial sector, ANSI/ASHRAE/IES Standard 90.1, Energy Standard for Buildings Except Low-Rise Residential Buildings. 

This study investigates the technical feasibility of achieving zero energy (ZE) new residential and commercial buildings with national model energy codes. The approach and analysis are intended to provide guidance, inform goal setting, and direct future code development.
