April 3, 2025
The U.S. Department of Energy announced it would withdraw four appliance efficiency standards and officially postpone the effective dates for three other rules. These rules cover test procedures for appliances such as central air conditioners and heat pumps, efficiency standards for walk-in coolers and freezers and standards for gas instantaneous water heaters. Read more

Last week, a federal judge found the extreme heat in Texas prisons to be “plainly unconstitutional,” but declined to order the state to immediately start installing air conditioning, which could cost billions. The judge affirmed claims brought by advocates of people incarcerated in the state, where summer heat routinely soars above 100°F (38°C). But they will have to continue pressing their lawsuit later in a trial. The lawsuit was initially filed in 2023 by Bernie Tiede, a former mortician serving a life sentence, and several prisoners’ rights groups then asked to join and expand his legal fight. Read more

Net zero. This simple accounting term represents humanity’s greatest challenge: to stabilize Earth’s climate. Since the dawn of the Industrial Revolution, the world has built up more than 250 years of momentum in a carbon-emitting economic and technological paradigm.

Condensation is an important phenomenon to be avoided in building elements. A study calculated the response of insulation of different thicknesses applied in two different wall types to minimize condensation in a building in four different heat zones in Turkey. The aim was to determine more clearly in which cases the building is protected from moisture damage and the extent to which thermal comfort is provided. Download here

In Case You Missed It
A federal judge issued an order last week blocking the U.S. Environmental Protection Agency’s freeze order on Greenhouse Gas Reduction Fund grants, finding that the EPA did not provide sufficient evidence of waste, fraud or abuse. The case was brought before U.S. District Court for the District of Columbia Judge Tanya Chutkan on March 8 by the Climate United Fund (CUF), the recipient of a $6.97 billion Greenhouse Gas Reduction Fund grant which was frozen Feb. 18 after the EPA issued a notice of termination regarding the $20 billion GGRF fund. Read more
