Before Gustavus Swift, if you ate meat, it practically walked right up to you. The Chicago meatpacking tycoon upended centuries of butchery by developing the refrigerated train car, thus allowing for the bestial growth of Chicago’s stockyards. He turned to the developing technology of refrigeration to avoid shipping and feeding live cattle (and maximize dollars from valuable byproducts) – and in the process, contributed to a refrigeration-enabled fundamental change in our relationship to food.

Anthony Pieri, an HVAC repair tech, Kansas, was forced to watch while his tools were stolen on the job last week in Kansas City, Mo. Pieri was repairing an air-conditioning unit on a Dollar Tree rooftop when the alleged criminals kicked over his ladder, stranding him as they broke into his work van. He snapped photos of the thieves in action in the hope of recovering his tools, which are not company-provided and valued at around $1,000. Read more |

Surging data center energy demands have caused Google's greenhouse gas (GHG) emissions to increase significantly in the last five years, posing a major setback to the tech giant's goal to achieve net zero emissions by 2030. The results of the tech giant’s annual environmental report show Google’s total emissions stood at 14.3 million tons of CO2 in 2023, marking a 13% increase year on year and a 48% increase compared to 2019, when the target was initially set. Google was clear the road to net-zero by 2030 will be difficult, acknowledging that as it pursues deeper AI integrations in its products, reducing emission will be increasingly challenging. Read more

Feature of the Week
By Alberto Cavallini, Fellow ASHRAE, Filippo Busato, Ph.D., Member ASHRAE, and Fabrizio Pregliasco
This article assesses the infection risk in several HVAC system layouts, taking into account the role of ventilation and air recirculation and the lowering of infection risk due to virus removal or inactivation (through mechanical or electrostatic filtration or inactivation technologies such as UV-C irradiation and ionization), with special attention to the management of airflows depending on plant layout.

In northern England, a 100-year-old house boasts a cutting-edge heat pump that’s making waves in the energy efficiency community. The machine boasts a coefficient of performance (COP) of 5.5, meaning for every kilowatt-hour of electricity it consumes, it delivers 5.5 kilowatt-hours of heat. In comparison, average heat pump COPs in the UK typically range between 2 and 3. Read more
