Shaping Tomorrow's Built Environment Today
July 4, 2024
New York's Building Code Council is set to include the All-Electric Buildings Act in its 2025 code update. The 2023 law bans natural gas and other fossil fuels in new buildings, with all-electric cooking and heating required for new buildings of less than seven stories by 2026, and 2029 for taller buildings. While the new language applies to new buildings, other programs exist for homeowners and building owners to go green. Read more
Innovation company WAVJA says their light-catching spheres may replace solar panels if they reach their potential. The tech, called Photon Energy Systems (PES), can harness both natural sunlight and artificial light as energy sources. Per WAVJA Executive President Shereen Chen, the 4-inch PES spheres are 200 times more efficient than solar energy, with potential applications like charging a smartphone to powering cars. Read more

The New York supermarket chain Gristedes will pay a $400,000 civil fine and spend $13.5 million on repairs and upgrades to settle charges that its store refrigerators emitted far more greenhouse gases than rivals' refrigerators Gristedes was accused of allowing 42,094 pounds of refrigerant leaks from its stores between 2019 and 2021, the greenhouse gas equivalent of driving a gas-powered car 140 million miles around the Earth's equator.  Read more
National Renewable Energy Laboratory researchers are planning for extreme weather by using a computer model to calculate what it will take to make extreme weather situations survivable. A newly-published study focuses on retrofit options for existing buildings and finds that the use of phase-change materials will significantly enhance hours of safety. Read more
Transitioning to Low Global Warming Potential Refrigerants
Join Ryan Shanley, Senior Manager of Standards, as he moderates this episode with guests Doug Reindl and Stet Sanborn on the transition from high GWP to ultra-low GWP refrigerants; the marketplace for A1, A2 and A3 refrigerants; and how this phase of flammable refrigerants use impacts ASHRAE Standard 15, Safety Standard for Refrigeration Systems, and ASHRAE Standard 15.2, Safety Standard for Refrigeration Systems in Residential Applications.

Under a proposed rule, the Environmental Protection Agency (EPA) would extend the date for the installation of some variable refrigerant flow (VRF) systems. Current regulations require that the installation of new VRF systems that use HFCs with a GWP of 700 or more cease after January 1, 2026. However, the proposed rule would extend this compliance date to January 1, 2027, provided that the components were manufactured in the US or imported prior to the original 2026 deadline. Read the pre-publication version of the proposed rule
