Shaping Tomorrow's Built Environment Today
July 25, 2024
According to a new study published in Science of the Total Environment, the materials in car cabins can release high levels of semi-volatile organic compounds (SVOCs), a group of potentially endocrine disrupting chemicals, into the surrounding air. The study showed that nine different SVOCs were detected in the air and dust of car interiors and that their concentration increased at higher temperatures, and that turning on the car ventilation system effectively reduced chemical exposure. Read more
A Portuguese research team has compared several applied machine learning techniques to perform fault detection in air-to-air heat pumps in cooling mode. They have identified four algorithms showing a high level of performance based on the metrics of accuracy, precision, recall, and F1 score, which is a key figure used to measure the performance of classifications. Python was used to conduct the comparative analysis of supervised learning classification algorithms for fault detection. Read more

Politicians in the US have called for the Federal Energy Regulatory Commission (FERC) to spell out how it will deal with growing electricity demand from AI data centers. Republican congressperson Cathy McMorris Rodgers, who chairs the House Energy and Commerce Committee, and Energy, Climate, and Grid Security Subcommittee chair Jeff Duncan have written to FERC requesting that the agency provide information on how it will deal with rising demand. Read more

The technical program is now available for the first Women in ASHRAE Leadership Symposium, set on the “Magnificent Mile” in Chicago, Illinois, September 26-27, 2024. Per symposium chair Nancy Kohout, “This symposium will explore meaningful actions and tangible initiatives we can undertake to expand and grow leadership roles for women in engineering, to improve the experience of women interns and entry-level professionals, to strengthen retention rates over the course of a career, and to provide a needed voice and perspective for how engineers can help drive organizational and cultural change.” Early bird registration is available through July 31.

In Case You Missed It
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.  Read more
