2021 IECC Beats NGBS on Energy Performance

Analysis conducted by ICF consulting compared the home energy performance of the 2020 National Green Building Standard (NGBS), the first residential green building standard to undergo the full consensus process from the American National Standards Institute (ANSI), and the 2021 Residential International Energy Conservation Code (IECC). The analysis showed that the NGBS is not equivalent to the 2021 IECC except possibly at the Emerald level, and all homes at the Bronze, Silver, and Gold levels result in worse energy performance and higher energy costs than the 2021 IECC.

IEA: Much Faster Progress on Energy Efficiency Needed

Yesterday, the International Energy Agency (IEA) released its Energy Efficiency 2024 report, concluding that much faster progress on global energy efficiency is needed to meet the climate pledges of COP28 held last year. Nearly 200 countries, including the United States, pledged to double the global annual average rate of energy efficiency during the event. One year later, a weak improvement of just 1 percent has been achieved. However, the report includes critical takeaways for the building industry and buildings.

Government-Backed Mortgages to Get Efficiency Boost

Yesterday, the U.S. Department of Housing and Urban Development (HUD) and the U.S. Department of Agriculture (USDA) announced a final rule updating the energy code requirements for HUD and USDA new home mortgages. All new construction homes purchased with these federal mortgages must now comply with the 2021 or the 2024 International Energy Conservation Code (IECC). While the final rule was announced today, enforcement of the rule will not come for 18 months. Currently, the rules require compliance with the 2009 IECC. This new requirement will increase the energy efficiency of new homes by more than 30 percent.

How the IRA Can Make Resilience Affordable

With the cost of homeownership skyrocketing and extreme weather on the rise, it’s increasingly important to know if your home is financially and physically resilient.

Housing affordability is a nationwide concern for homeowners. Rising costs across insurance, taxes, and utilities are creating serious financial strain. These rising costs are alarming enough, but when combined with the increasing threat of severe weather events, like the recent snowstorm in Portland, Oregon, that left 132,000 people without power for over a week, risks are leading homeowners to question if they’re properly prepared.

$180M Funding Opportunity for Schools Announced

The U.S. Department of Energy opened applications Wednesday for the 2024 Renew America’s Schools prize, which will award $180 million in funds to school districts nationwide to implement energy upgrades.

The prize, funded by the Biden Administration’s Infrastructure law, represents a significant opportunity for K-12 schools to improve infrastructure. Research has shown that improving school infrastructure through such activities as adding insulation reduces costs, improves student health, and contributes to better learning.

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.
