Shaping Tomorrow's Built Environment Today
June 20, 2024
A recent house listing on Zillow has homebuyers scratching their heads but may prove tempting to a data center company that wants to relocate to the heart of a Dallas, Texas suburb. The $2.4 million property, masquerading as a 5,786 ft2 McMansion style family home, has no bedrooms, one bathroom and an immersion liquid cooling system inside. The property listing includes all of its cooling and power infrastructure, including single-phase liquid immersion cooling tanks for use with dielectric coolant, with pumps and a 500kW dry cooler. The tanks are currently filled with at least 80 mining computers visible from the photos, though they can be configured to fit more machines. Read more
Texas Home Listing Boasts Data Center with Full Liquid Cooling Immersion System, No Bedrooms

A new approach to electrification may help companies generate carbon-free process heat. Researchers from ETH Zurich and the Eastern Switzerland University of Applied Sciences have developed a solution that enables heat pumps to generate heat cheaply and flexibly at various temperatures of up to 200°C (392°F). The study, published in the International Journal of Refrigeration, employed a novel blend of refrigerant in the technology to achieve energy and cost savings. Read more
A new bipartisan bill in the U.S., dubbed The Supercritical Geothermal Research and Development Act (HR 8665), seeks to establish and support a framework for research and testing of supercritical geothermal technologies at the Department of Energy. Supercritical geothermal, sometimes referred to as superhot rock energy, is a category of enhanced geothermal systems that requires deep drilling technologies to access dry rocks at temperatures around 400°C (752°F) or greater. These systems can supply about five to ten times more energy per well compared to conventional hydrothermal systems. Read more
Transitioning to Low Global Warming Potential Refrigerants
Join Ryan Shanley, Senior Manager of Standards, as he moderates this episode with guests Doug Reindl and Stet Sanborn on the transition from high GWP to ultra-low GWP refrigerants; the marketplace for A1, A2 and A3 refrigerants; and how this phase of flammable refrigerants use impacts ASHRAE Standard 15, Safety Standard for Refrigeration Systems, and ASHRAE Standard 15.2, Safety Standard for Refrigeration Systems in Residential Applications.

In Case You Missed It
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 towards zero emissions across the entire sector while cutting home and business energy costs.
