Shaping Tomorrow's Built Environment Today
March 13, 2025
The Trump administration has withdrawn the US from a global agreement under which the developed nations most responsible for the climate crisis pledged to partly compensate developing countries for irreversible harms caused by global heating. The loss and damage fund was agreed at the COP28 UN climate summit in late 2023 after years of diplomatic and grassroots advocacy by developing nations that bear the brunt of the climate crisis despite having contributed the least to greenhouse gas emissions. Read more
Researchers from China have proposed to combine solar-air source heat pumps (SASHP) with sand-based thermal floor storage in rural clean heating renovation projects. The system, which links a SASHP heating system to a sand-based thermal storage floor, can maintain an average indoor temperature of 18.8°C (65.84°F), even when outdoor temperatures range from −18.4°C (-1.12°F) to 12.3°C (54.14°F). Read more
Google Cloud has announced a collaboration with SLB and Project Innerspace to accelerate the global adoption of geothermal energy. Geothermal energy has the potential to satisfy global electricity needs up to 140 times, according to a recent International Energy Agency (IEA) report in collaboration with Project Innerspace. Read more

In a new study, researchers from SUNY Albany use a decade and a half of data from New York State to explore the impact that replacing or improving HVAC systems had on reading and math scores, as well as absenteeism and suspension rates. To assess HVAC systems, the researchers pulled data from the New York Building Conditions Surveys on cooling and heating systems and ventilation systems. Read more

In Case You Missed It
Declaring a state of emergency, California Gov. Gavin Newsom suspended two state environmental laws to expedite measures he said were needed to protect communities against wildfires. Newsom suspended the California Environmental Quality Act and the California Coastal Act as the two-month anniversary of the Palisades and Eaton fires approaches. The moves come as Newsom asks Congress for nearly $40 billion in aid for fire recovery and also follows President Trump's criticism of the state’s wildfire management. Read more
