The energy efficiency, cost savings, and versatility of heat pump water heaters (HPWHs) make them a clear choice for the environment and households across the U.S. With 120 million water heaters in the U.S. alone, we could save over 100 million tons in...
Greenhouse gas emissions from the airline industry are reaching new heights. By 2050, more than a quarter of all global emissions are expected to come from the aviation industry, according to a UN report. While many individuals and organizations are...
ASHRAE, along with 24 of the world’s leading building industry organizations, issued a statement a few months ago to government representatives attending the United Nations Climate Change Conference of the Parties (COP 27) pledging to assume a leadership role in...
Central heat pump water heaters (CHPWHs) present a tremendous opportunity to reduce the substantial energy used in water heating and can act as giant thermal batteries. They do this by using energy to heat water during times of low grid...
During the summer of 2022, there were more than 7,000 record-breaking daily temperatures reported across the U.S., according to data from the National Oceanic and Atmospheric Administration (NOAA). Dangerously high temperatures in the U.S. impacted more than 40 million people,...
Building efficiency and decarbonization is a movement that has the potential to dramatically curb climate change and make buildings healthy and productive spaces. K-12 schools, where staff and students spend at least 1,000 hours each year, are leading the way....
In our new podcast series, we dig deeper into the research papers authored by NBI staff. We begin with NBI staff that presented at the 2022 ACEEE Summer Study on Energy Efficiency. Professionals from around the world came together at...
Over the past 15 years, many jurisdictions have reduced operational emissions in buildings through policies focused on energy efficiency, resulting in lower energy bills, better indoor air quality, and increased comfort. As the carbon emissions associated with operating buildings continues...
The 2024 draft Residential International Energy Conservation Code (IECC) is now out for public comment. The provisions in the 2024 code will build on the energy efficiency advancements made in the 2021 code cycle and introduce key provisions to address...
In an effort to combat climate change, lawmakers in many parts of the U.S. are pushing for building electrification—or the phasing out of fossil-fuel powered appliances and heating and cooling systems in the built environment. It’s very encouraging to see...
