Shaping Tomorrow's Built Environment Today
January 23, 2025
Hours after taking office, U.S. President Donald Trump signed an executive order directing the United States to withdraw from the landmark Paris climate agreement. Trump also signed a letter to the United Nations indicating his intention to withdraw from the 2015 agreement, which allows nations to provide targets to cut their emissions of greenhouse gases from the burning of coal, oil and natural gas. Those targets will become more stringent over time, with countries facing a February 2025 deadline for new individual plans. Read more

Trade organizations representing builders, developers and building owners joined Washington Gas & Light in filing a lawsuit challenging Maryland’s emissions reduction requirements for large buildings. The suit alleges that Maryland’s regulation requiring buildings of at least 35,000 ft2 to reduce their global-warming emissions to net zero by 2040 is unlawful because federal law gives the U.S. Department of Energy the power to set energy standards for appliances, not states. Read more
As humid air starts to accumulate inside and condensation forms on windows and poorly insulated walls, it can be a hassle checking every corner, every week for potential mold damage. German researchers have found a simple solution, however, with a rapid five-minute trick to help prevent mold by using stoßlüften, or "shock ventilation," in their homes. Read more
Researchers in Iran have designed a concentrating photovoltaic (CPV) system that integrates parabolic reflectors, a paraffin-based nanomaterials cooling system and a thermoelectric generator that turns waste heat into electricity. Simulated results demonstrated that, with the cooling system in place, the PV efficiency improves by approximately 16.46% in clean conditions. Read more
