Shaping Tomorrow's Built Environment Today
October 12, 2023
The U.S. Environmental Protection Agency has finalized standards that will phase out the most climate-warming hydrofluorocarbons (HFCs) in key applications, from aerosols to heat pumps; supermarket refrigerators to vehicle air conditioners. At the same time, the EPA proposed new rules to cut refrigerant leakage, promote reclamation and reuse and mandate the use of reclaimed refrigerant when making and servicing many new products. These EPA rules are two key pieces of the American Innovation and Manufacturing (AIM) Act, the climate law enacted in 2020 to cut the use of these super-pollutants by 85% over 15 years. Read more
The AHR Expo (International Air-Conditioning, Heating, Refrigerating Exposition) today announced the winners of the 2024 AHR Expo Innovation Awards. Winners are chosen annually in 10 industry categories, representing the most innovative products and technologies in the market. Read more
The Green Building Council’s Leadership in Energy and Environmental Design (LEED) certification is subsidized or required by more than 350 local and state governments and the U.S. General Services Administration. However, the influential rating system largely overlooks the growing impacts of climate change, despite increasingly frequent and severe climate-related disasters. As a result, the Green Building Council has affixed its coveted three-leafed seal to more than 800 new buildings in the past decade that are at extreme risk of flooding, according to an analysis by POLITICO’s E&E News and the First Street Foundation. Read more
Kelley Cramm, P.E., Life Member ASHRAE, and Drew Champlin, Editor of ASHRAE Journal, discuss the basics of VRF systems and how to keep them from failing. Learn more on installation practices and how engineers and contractors can ensure owners are getting a quality installation.

VRF Basics & Proper Installation Techniques
Thirteen U.S. states are now implementing underground thermal energy networks to reduce buildings’ carbon emissions as part of a nationwide push to adopt cleaner energy sources. When installed, these networks can provide efficient, fossil fuel-free heating and cooling to commercial and residential buildings. Thermal energy networks rely heavily on underground piping systems, presenting an opportunity for workers with expertise in maintaining natural gas pipes to transition seamlessly into roles on those kinds of projects. Read more

ASHRAE Journal
By David Sellers, P.E., Member ASHRAE
Outdoor environmental conditions are major drivers for building heating and cooling loads. The author has been interested in meteorology for most of his life and has have learned much about climate data acquisition and reporting in real time. However, he wasn’t as familiar with how the normalized (for example, typical meteorological year or TMY) data sets are developed. But thanks to a recent project, he was able to explore that topic and learned some surprising things. In this column he shares some of those insights. Download here
ASHRAE is a leader in developing guidance proven to safeguard public health. As the world grapples with a resurgence of COVID-19, along with the spread of flu and RSV, the importance of clean air flow in buildings has never been more critical. Now, the Society’s pioneering resource, ASHRAE Standard 241, Control of Infectious Aerosols, provides building owners, operators and professionals the ability to proactively protect indoor environments during this fall and winter virus season.

TRACvalve reduces the horsepower required by the system's central pumps. By metering overall demand, central plant efficiency is improved up to 40%. Adjusts to the design LAT, maintaining a high Delta-T across the coil. Variable fluid flow reacts to room and system changes, reducing GPM at a lower load demand.

The Biden administration released last week a plan to increase climate resilience nationwide. The “National Climate Resilience Framework” identifies the federal government’s six overarching climate resilience goals and provides specific actions that could be taken to accomplish them. The plan says it centers locally tailored, community-driven solutions. The framework “will help guide wise investment of federal dollars” and indicates that the government is moving beyond traditional disaster response, said Shana Udvardy, a climate resilience analyst at the Union of Concerned Scientists, in a statement.
