NREL: Envelope Upgrades Can Save Thousands with Heat Pumps

The Inflation Reduction Act provides thousands of dollars in rebates or tax credits for homeowners installing heat pumps. However, even without those rebates, heat pumps would be cost-effective in 65 million U.S. households, according to the National Renewable Energy Laboratory (NREL) research. Further, electrification with heat pumps can reduce greenhouse gas emissions in every U.S. state. However, there is broad variability in the economics of heat pumps after installation, depending on several conditions. Envelope upgrades being one of them.

Cool Tech: The Polymer That Could Boost Efficiency

Residential dehumidification has several benefits, including improved comfort, prevention of mold and mildew, and better respiratory health. Low humidity enabled by dehumidifiers also helps air feel cooler, allowing residents to set their thermostats at higher in the summer without sacrificing comfort. This can reduce the workload of the air conditioning system and save homeowners money.

Bolstered by Policy, Clean Energy Thrived in 2023

Driven by the passage of the Infrastructure Investment and Jobs Act and the Inflation Reduction Act (IRA), the clean energy transition saw a record-shattering year in 2023, according to the Business Council for Sustainable Energy (BCSE) and BloombergNEF in the Sustainable Energy in America Factbook, released Wednesday. The report focuses on clean energy technologies, including renewables, electric vehicles, power grid investments, energy efficiency, and other sectors, and details the more than $303.3 billion in financing deployed in the U.S. last year on clean energy investments.

3 Ways AI is Delivering on Energy Efficiency

Would it surprise you to learn that 82 percent of companies are currently using or exploring artificial intelligence (AI) in their operations? Further, 84 percent report they are increasing their investments in data and AI.[1] That’s because AI has a near limitless capability to aid businesses and organizations in their effort to help boost energy efficiency, reduce carbon emissions, support clean energy technologies, and address climate change. Here are three specific ways AI is driving energy efficiency.

4 Resources for BPS Implementation Education

State and local governments across the country are adopting Building Performance standards (BPS), and the pace of adoption for such standards will only accelerate as jurisdictions look to cut greenhouse gas emissions, boost building energy efficiency, and lower energy use. In 2023, 10 local jurisdictions across the U.S. launched BPS policies, including New Jersey, California, Colorado, Maryland, and Minnesota.

Number of HERS-Rated Homes Tops 360K in 2023

Residential Energy Services Network (RESNET) has released data on the number of Home Energy Ratings Score (HERS)-rated homes in 2023. More than 360,000 homes were HERS rated last year, an increase of more than 22,000 homes compared to 2022. This accounts for 28 percent of all new homes built last year. The cumulative number of HERS-rated homes in the U.S. now tops 3.9 million, a stunning figure when you consider that just two years ago, the number of HERS homes reached 3 million.

How 12 Standards Stack Up on Performance

A new report from Emu Passive, which specializes in Passive House training and consulting, looks at the ability of 12 building standards to deliver resilience, a healthy environment, and efficient buildings. The research examines how the various building standards perform based on the most common challenges for buildings. PHI Passive House performed the best among the standards considered, but more details on the performance of each standard emerge within this research.

Can the Gamification of EE Deliver Success?

Researchers at Purdue University this week announced the creation of a patent-pending Internet of Things (IoT) software program called MySmartE that incentives people to use energy efficiency programs offered by the government and industry. Why does that matter? The lack of residential engagement with energy efficiency programs to measurably reduce energy use is stymying efforts to decarbonize the built environment, a priority for virtually every government and industry. Early results show that gamification might just do the trick.
