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, and economic and social development. This policy brief seeks to support building code policymakers and implementers in designing effective building code programs.
Key design elements and good practices, drawn from global experience and lessons, can support effective building code development and implementation, tailored to meet country-specific goals. Use model building codes to inform interlinked national and subnational building code efforts. These policy designs and good practices include:
1. Use model building codes to inform interlinked national and subnational building code efforts
2. Engage stakeholders throughout the process to secure support for adoption and implementation
3. Conduct robust analysis to assess costs and benefits, inform code design, and provide a foundation for policy evaluation
4. Develop a comprehensive and long term building code strategy, increasing in stringency over time
5. Build strong compliance infrastructure to ensure effective building code enforcement
6. Educate building sector stakeholders and code officials on the importance of building energy codes to increase support for compliance and recognize strong performance
7. Rigorously evaluate energy codes to understand strengths and weaknesses and support improved policy design and implementation over time
8. Provide ongoing capacity building, training and resources to sector stakeholders to build support for code compliance and ensure effective design and implementation
9. Capture benefits of interlinked policies through designing a strong policy framework
In response to feedback, high-income households can reduce their energy use to a larger degree than low-income households (17% vs 3% reduction). This and other insights were gained by two rapid reviews into research, both Australian and International, on digital services and...Read more
Industry misconceptions around high cost and poor market interest in energy efficient homes continue to obstruct the mass adoption of low carbon housing. Josh’s House demonstrates that low carbon housing is accessible and cost effective. The Star Performers series showcases how...Read more
A rapid review on green-rated office buildings, and their operational energy use, found that the conclusions of six studies ranged from the certified buildings performing worse, similarly or much better than the non-certified buildings in terms of energy usage intensity. Two...Read more
1. As a result of Colombia’s new green codes, buildings are expected to consume 10 to 45 percent less energy and water. These reductions will avoid nearly 190,000 metric tons of greenhouse-gas emissions by 2021, helping big cities like Bogota achieve a goal to reduce 2019’s greenhouse-gas emissions by 16 percent compared to 2007.2,3
This is a presentation for U.S. Department of Energy 2017 National energy codes conference July 18—20, 2017 Pittsburgh, PA. USA.
The slides presented a case study about the impact of carbon policy changes in NYC on the existing buildings and energy code in NYC.
As a result, several other existing building codes and policies in NYC has to be amended accordingly:
