The carbon footprint of a building starts at its inception, not when its occupants move in. Products like concrete, steel, aluminum, and insulation are key building components, but until recently were rarely considered by design and construction teams for their...
To succeed in decarbonizing our energy systems, we will be relying much more on variable renewable resources like wind and solar energy—but we’ll need to do more than install more clean generation resources. We’ll also need to get better at...
Energy-efficient water heating took significant strides in 2022, according to the latest data released by ENERGY STAR. Sales of heat pump water heaters (HPWHs) grew 26% last year while sales of gas water heaters declined by 17%, underlining a clear...
Electrifying and decarbonizing existing buildings is critical to address the climate emergency and is one of the key priorities of leading cities, states, and utilities. Many people assume that to electrify an existing home, an electric panel upgrade from 100...
Have you ever visited a zoo or aquarium? How about an art museum, a botanical garden or arboretum, or a historic site? With over 33,000 cultural institutions in the U.S. (UNESCO reports), my guess is that you have been to...
With historic federal funding setting the stage, the seventh iteration of the Getting to Zero Forum was an opportunity to convene at a pivotal time, when there is more support and resources for decarbonizing the built environment than ever before....
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...
