The standards will bring cumulative emission reductions of nearly 101 million metric tons of carbon dioxide, the Department of Energy said, an amount roughly equivalent to the combined annual emissions of 12.7 million homes. Source: Alejandro Cegarra/Bloomberg
 
The Biden administration announced a final rule on Friday that imposes stricter energy efficiency standards for residential refrigerators, freezers and refrigerator-freezers, promising savings and environmental benefits. The new standards for those energy-guzzling consumer appliances, which haven’t been updated in over a decade, will save consumers $36.4 billion over 30 years of shipments, the DOE estimated in a press release.

Several parts of The United States could be underwater by the year 2050, according to a map produced by Climate Central. The map shows what could happen if the sea levels, driven by climate change, continue to rise at rates of 2 mm and 4 mm. Read more

A new breed of heat pumps is emerging—ones that are able to supply much higher temperatures, sometimes in excess of 70°C (today's gas combi boilers are typically designed for flow temperatures of around 50-60°C). A major change has been the rise of new refrigerants, including R290, or propane, which is the fluid that circulates inside a heat pump. R290 is also up to 34% more efficient, which helps heat pumps supply higher temperatures without incurring severe efficiency losses. Read more
 
The multinational company Equinix has made a total allocation of $4.9 billion in investment-grade green bonds, inching closer to its near-term target of climate neutrality by 2030. During the last five years, the bonds supported 172 green building projects across 105 sites, 33 energy efficiency projects, and two Power Purchase Agreement (PPA) projects. The PPAs support 225 megawatts of renewable energy capacity, which are expected to mitigate or avoid 383,300 metric tons of CO2e annually—the equivalent to emissions from over 85,296 gasoline-powered passenger vehicles driven annually. Read more

Feature of the Week
By Alec Cusick, Associate Member ASHRAE
Chilled water piping is used in a range of situations—from data centers to airports and across multibuilding campuses in district energy systems. Although these systems face several threats—such as condensation and vapor pressure—in terms of long-term function, a properly designed and installed insulation system can preserve longevity. Designing an insulation system to have the required amount of thickness and sufficient moisture resistance coupled with a jacketing that has the right emittance can help mitigate the risks posed by condensation, water vapor and unexpected mechanical damage. Protecting the chilled water system in these ways helps ensure efficient long-term function and reduces the need for unexpected repairs. Download here

Air Pollutants Commonly Found Indoors Could Impact Creativity, Scientists Find

Air quality in the office may affect our creativity at work, scientists at Nanyang Technological University, Singapore (NTU Singapore) have discovered. The NTU Singapore scientists found in a study that high levels of VOCs—gases released from products such as detergents, pesticides, perfumes, aerosol sprays and paint—affected the study participants' creativity when they were asked to build 3D models with Lego bricks. The findings detailed in the study, published in Scientific Reports, shed light on the importance of indoor air quality on our creative cognition, said the research team led by Assistant Professor Ng Bing Feng and Associate Professor Wan Man Pun, Cluster Directors for Smart & Sustainable Building Technologies at the Energy Research Institute. Read more
