Residential and commercial buildings accounted for over 2,000 Million Metric Tons (MMT) of carbon equivalent emissions and 40% of the total energy consumed in the United States in 2016. New construction and major renovations in buildings have a long-term impact on emissions as many of the features incorporated at time of construction will impact energy consumption for decades.
In cities, the building sector is a major contributor to carbon emissions. Some jurisdictions may have climate policies and climate action plans that set targets and lay out an action plan for improvement on the path to zero carbon emissions. Other jurisdictions, like states and cities, may not have explicit climate goals, but they have an interest in improving building performance and reducing energy costs for their constituents.
Moving Energy Codes Forward: A Guide for Cities and States explains how energy codes can be a critical part of carbon reduction strategies and outlines steps to achieve significant code improvements. It links jurisdictions to leading design measures and new technologies which may be adopted as a stretch code, incorporated into incentive programs or policy initiatives, and eventually integrated in local and national code advancement efforts. It also offers guidance, resources and examples of advanced code adoption based on experiences in other communities.
Although local jurisdictions are unique in needs and specific implementation approaches, this guide provides a practical framework for implementing advanced codes and policies.
Research identifies that home design needs to considers both energy efficiency and heat stress resistance. Currently, NatHERS only focuses on energy efficiency. If the building codes are not modified, then house designs which only focus on NatHERS could adversely impact people's...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
When South Eastern Australia was in severe drought at the beginning of the century, a whole array of efforts went into addressing the water shortage. Councils introduced, and then increased, water restrictions. Government handed out low-flow showerheads and shower timers,...Read more
Since 2010, New Buildings Institute has tracked the developing market for zero energy buildings. We are pleased to share this latest 2018 Getting to Zero Status Update and Zero Energy Buildings List, which summarizes the growth and trends from nearly 500 certified, verified and emerging zero energy projects across the United States and Canada.
The latest version of the EU Energy Performance of Buildings Directive (EPBD) aims to achieve a highly energy efficient and decarbonised building stock by 2050, and compels Member States to develop respective roadmaps, guidelines and measurable, targeted actions.
The buildings sector is responsible for approximately 23% of Australia’s carbon emissions. The Australian Sustainable Built Environment Council (ASBEC), the peak body for sustainability in the built environment, has identified that improving the minimum standards for energy efficiency of new buildings can assist in delivering carbon emissions reductions.
The populations of most world cities are growing fast, and with it come challenges and opportunities for keeping citizens safe and well. New International Standards for measuring and improving the performance of cities have just been published:
