Shaping Tomorrow's Built Environment Today
March 7, 2024
ASHRAE received a determination issued by the U.S. Department of Energy (DOE) stating that ANSI/ASHRAE/IES Standard 90.1-2022, Energy Standard for Sites and Buildings Except Low-Rise Residential Buildings, will increase energy efficiency in commercial buildings subject to the code. The standard achieved this determination through the DOE’s technical analysis estimating that buildings meeting 90.1-2022 (as compared to the previous 2019 edition) would result in a national average site energy estimate savings increase from 9.8% to 14% (reference as “net” savings). Read more
A Southern California man was arrested Monday on suspicion of smuggling refrigerants into the U.S. from Mexico. Federal prosecutors said he's the first person to be charged with violating regulations intended to curb the use of greenhouse gases that contribute to climate change. The indictment alleges the ozone-depleting chemicals were smuggled across the border concealed under a tarp and tools in the San Diego resident’s vehicle. Read more
Ohio Research Proposes Coupling Geothermal with Direct Air Carbon Capture

A study at the Ohio State University proposes a method for developing a system combining direct air CO2 capture technologies (DACC) with CO2 Plume Geothermal, allowing for large-scale carbon dioxide removal with few emissions, creating a climate-benign direct air CO2 capture, utilization and storage system. The study introduces a strategy for geologic CO2 in a deep, porous and permeable aquifer with sufficient geothermal heat flux.  Read more

Artificial intelligence (AI) has the potential to operate buildings more energy efficiently, sustainably and comfortably. Many potential applications exist for AI in the built environment sector, including building design, building performance optimization, energy management and monitoring and building maintenance and operations. The significance of AI in optimizing the performance of buildings and its applications and limitations are discussed in this work. Download here

Researchers at the University of Birmingham in England claim they can extend the range of battery-electric vehicles (BEVs) by 70% using a car’s air-conditioning system powered by microwaves to cope with extreme temperature effects. The team is developing an energy storage system to boost BEV driving range during hot or cold weather when the vehicle’s climate control system is consuming enough electric energy to cut the working range by up to 40%. The process couples a chemical heat pump with microwave energy to produce heating or cooling on demand and at much higher energy density than from the vehicle’s battery pack. Read more
