Shaping Tomorrow's Built Environment Today
June 13, 2024
On June 6, the U.S. Department of Energy (DOE) announced a National Definition of a Zero Emissions Building to advance efforts to decarbonize the buildings sector, which is responsible for more than one-third of total U.S. greenhouse gas emissions. This definition is intended to provide industry guidance to support new and existing commercial and residential buildings to move toward zero emissions across the entire sector while cutting home and business energy costs. Read more
The lunar environment oscillates between blistering highs and frigid lows. Future missions to explore the moon will need reliable machines that can function under these harsh conditions. This led a team from Nagoya University in Japan to invent a heat-switch device that promises to extend the operational lifespan of lunar-roving vehicles. Their study, conducted in collaboration with the Japan Aerospace Exploration Agency, was published in the journal Applied Thermal Engineering. With a lower pressure drop than passive valves and lower power consumption than heaters, the thermal control device retains heat at night without compromising daytime cooling performance. Read more
Heat-Switch Device Boosts Lunar Rover Longevity in Harsh Moon Climate.
As data centers face escalating power demands, trailer-mounted power generators are emerging as a potential solution. These mobile units can be positioned in parking lots, providing critical power to facilities struggling with internal and external power limitations. Internally, the power requirements of processors in densely packed racks have surpassed the electrical capacity of many data centers. Externally, power shortages in metropolitan areas and prolonged timelines for new power generation projects exacerbate the issue. Read more
Andy Pearson, Ph.D., C.Eng., Fellow ASHRAE, joins ASHRAE Journal Technical Editor Rebecca Matyasovski to discuss the upheaval in which scientist Sadi Carnot performed his work for the science we now call “thermodynamics.” Read the accompanying feature article from the June 2024 issue of ASHRAE Journal here.

ASHRAE and the GCC Standardization Organization (GSO), the standards organization for the member states of the Gulf Cooperation Council and Yemen, have signed a Memorandum of Understanding formalizing the organizations’ relationship. The agreement defines ASHRAE’s and GSO’s intent to work cooperatively to promote the implementation and use of global buildings standards to support sustainable building design and operations.

The Spanish city of Valencia has an innovative plan to generate clean energy—turning cemeteries into hubs of green energy by installing solar panels on top. The project has been dubbed Requiem in Power, or RIP, and was launched in May with the goal of becoming the largest urban solar farm in Spain. Valencia has identified multiple cemeteries within city limits that can accommodate 6,658 solar panels, with 810 already installed at multiple locations. When complete, the project will generate over 440,000 kilowatts of energy and save 140 tons of carbon emissions every year. Read more
