BUILDING ENERGY CODES: HOW TO ENSURE THEY DELIVER
Moderator: Yamina Saheb, OpenExp
This session will focus on building energy codes and their impact in reducing energy consumption if well implemented and effectively enforced. The authors will share the North American (Canada and the United States) experiences related to the evaluation of building energy codes’ impact and compliance improvements.
The 1st paper is from K.H. Tiedemann and I.M. Sulyma, Research 4 Results in Vancouver. The authors provide an evaluation of the impact of the British Columbia Building Energy Code on residential energy consumption. The evaluation is based on an innovative approach which combines on-site data from 800 dwellings, energy use information, survey data and computer simulations. The evaluation includes building energy code development, training, compliance and enforcement. The authors conclude with recommendations to policy makers on code development and compliance.
The 2nd paper is from J. I. Stewart, Cadmus Group in Portland. The author provides an estimate of efficiency improvements of space heating in new buildings as a result of the implementation of building energy codes in the US. Annual energy saved in residential space heating in the US is estimated at 7% which is equivalent to about 3% of overall annual residential consumption of the country. The author concludes with a set of recommendations to better address heating consumption in codes design and implementation.
The 3rd paper is from Issac Elnecave, Midwest Energy Efficiency Alliance in Chicago. The author presents the methodology developed by the United States Departement of Energy (US-DoE) in 2014 to assess building energy codes’ compliance and estimate the savings potential resulting from their effective implementation. The paper provides detailed results on the implementation of the methodology in Kentucky and identifies areas for improvement of compliance checking.
