Focus: Adoption, Compliance, Enforcement

Pacific Northwest National Laboratory (PNNL), funded by DOE, conducted an assessment of the prospective impacts of national model building energy codes from 2010 through 2040. A previous PNNL study evaluated the impact of the Building Energy Codes Program1; this study looked more broadly at overall code impacts. This report describes the methodology used for the assessment and presents the impacts in terms of energy savings, consumer cost savings, and reduced CO2 emissions at the state level and at aggregated levels.

Document type: Analysis, Reports and Studies
Release date: March 2017
Focus: Adoption, Compliance

This study used a three-step process to evaluate the degree to which high-impact controls requirements included in commercial energy codes are realizing their savings potential. The three-step process included: (1) interviews of commissioning agents; (2) field audits of a sample of commercial buildings to determine how well control measures are being designed, commissioned and correctly implemented; and (3) analysis of the information gathered.
