Humidity can influence employee health and productivity in the workplace. Humidity, temperature, and ventilation all work in concert to create a healthy indoor environment that supports overall occupant well-being. “Dry indoor air can cause discomfort in the form of dry skin, eyes, and throat for staff and visitors,” says Jennifer Montville, Director of Marketing at DriSteem, a manufacturer of humidification systems. Air-related health issues “There are real costs associate...
It takes a proliferation of data centers to serve the growing computing needs of the Internet, and all those servers churning away create plenty of heat. Might some of that heat be harnessed and used for residential or commercial heating? The emergence of district heating systems, which provide thermal energy to multiple buildings from a single source, demonstrates the approach has broad possibilities. Air-cooled chillers and air-handling units used to cool data centers are like the technologi...
Recently, nine states pledged to accelerate the transition to clean buildings in their states, including a goal of deploying heat pumps to make up 65% of residential heating, cooling, and water heating by 2030. California, Colorado, Maine, Maryland, Massachusetts, New Jersey, New York, Oregon, and Rhode Island signed a memorandum of understanding in February outlining their collective efforts to accelerate the deployment of clean technologies such as heat pumps in new and existing homes. ...
The flammability of the new class of low-GWP refrigerants is a source of misunderstanding and unnecessary anxiety among contractors who will be working with the newer materials, which must be used by HVAC equipment manufactured beginning Jan. 1, 2025. A2L refrigerants The newer A2L refrigerants, specifically R-454B, perform similarly to previously used materials such as R-410A, and flammability is so mild as to be almost negligible. What’s needed is more education to make co...
The idea of Energy as a Service involves shifting the traditional business model from selling energy as a commodity to providing a comprehensive package of goods and services to address a customer’s energy use and management. Rather than selling energy, the approach encompasses complete stewardship of a company’s energy needs in exchange for a monthly fee. Because 40% or so of a company’s typical energy needs are related to heating and cooling systems, implementing Energy as...
