To understand the operation of combustion air openings, it’s a good idea to review some airflow basics. For airflow to move through a duct, there must be a pressure difference across it created by an external source. Traditional installations depend on natural forces to create this pressure difference.
The Sierra Club, a grassroots environmental organization, announced it would be joining nonprofit public interest law organization, Earthjustice; the Consumer Federation of America; the Natural Resources Defense Council (NRDC); and a coalition of state attorneys general in filing a lawsuit against the Trump administration over the U.S. Department of Energy’s (DOE) delays in issuing new energy-efficiency standards for ceiling fans, freezers, boilers, and commercial and consumer goods.
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.
