Retrocommissioning refers to identifying improvements that can increase the energy savings and performance of existing buildings. Considering that about half of all commercial buildings in the U.S. were constructed before 1980, it’s easy to see why there is a growing demand for contractors who offer retrocommissioning.
Chillers have long been the HVAC systems of choice for large commercial buildings and other facilities, but they are facing fierce competition from new technologies, such as VRF systems, which are frequently considered to be easier to install and maintain.
While modeling software is often used for the initial design of high-performance buildings, the on-going benchmarking, commissioning, and monitoring of these structures is usually the purview of a building automation systems (BAS).
HVAC systems in commercial buildings consume a lot of energy, which is why many building owners and managers are looking at replacing their older, inefficient equipment with new high-performing systems.
Traveling, at least to me, offers a lot of lessons about human nature, life, and yes, the HVAC industry. It can be a microcosm of entrepreneurship and business acumen. What? That’s crazy, right? But not really.
Most HVACR technicians will need to raise their levels of safety consciousness when servicing equipment using flammable hydrocarbon (HC) refrigerants, such as R-290 (propane) or R-600a (isobutane), and the first place many technicians are likely to encounter these HCs will be in smaller kitchen equipment, such as reach-in coolers.
