When the HVAC industry expressed a need to reduce the time necessary to balance a system, Dwyer Instruments Inc. responded with the PredictAir™ Application Software (used with the Dwyer SMART Air Hood® Balancing Instrument) — the 2017 gold award-winning product in the Contractor Services and Software Category.
Innovative design hinders the growth of hazardous cooling tower-borne pathogens
July 24, 2017
A new Center for Disease Control and Prevention (CDC) study involving 196 cooling towers nationwide found that 84 percent contained Legionella DNA, indicating that the dangerous bacteria that causes a severe, even fatal type of pneumonia were present or had been at some point. This means the real question is not “whether there will be another outbreak” but only “where and when” it will occur.
The NEWS’ 2017 Dealer Design Award gold-winning Testing & Monitoring product, the AVUL Air Velocity Transmitter from Dwyer Instruments Inc., was designed to quickly and accurately measure air velocity or volumetric air flow in variable air volume (VAV) units, HVAC ducts, fume hood exhausts, and/or air-handler units.
How do we get new products or services to take root? The key is to find a champion. By having at least one tech who is excited about the potential of the offering, you can get a lot of traction. This technician will set the bar high by offering the item consistently and sharing their happy customer stories. This enthusiasm is contagious and will spread throughout the team. That champion also becomes the resident subject matter expert and supports the rest of the team, so they become more comfortable.
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).
