Rigorously enforced stringent building codes can cost effectively achieve energy savings, reduce energy bills and curb greenhouse gas emissions. This paper combines on-site data from some 800 dwellings, energy use information, survey data and computer simulations to evaluate the impact of the most recent energy efficiency provisions of the British Columbia Building Code on residential...

While government policies aim to increase residential energy efficiency, policymakers know little about the efficiency of the U.S. housing stock and improvements in efficiency over time. This paper estimates the average space heating efficiency of U.S. homes, improvements in residential space heating efficiency over time, and impacts of building energy codes on residential space heating...

The Government’s recent efforts to improve household energy efficiency have consisted of supplier obligations—such as the Energy Company Obligation (ECO)—and the marketled ‘pay-as-you-save’ Green Deal. These policies have proved inadequate. ECO has delivered many improvements but at much lower rates than previous supplier obligation schemes. The Green Deal did not increase demand for energy efficiency...

This report, based on the very latest available data, describes each company, explains how the company creates climate pollution and summarises what each says on the public record about climate change.

Globally, 32% of total final energy consumption is attributed to the building sector. To reduce energy consumption, energy codes set minimum energy efficiency standards for the building sector. With effective implementation, building energy codes can support energy cost savings and complementary benefits associated with electricity reliability, air quality improvement, greenhouse gas emission reduction, increased comfort...
