VAV diffusers drop service calls and operating costs in North Carolina
Koury Corporation owns and manages more than 1.3 million sq ft of office and industrial properties in the Greensboro, NC area. A fully integrated real estate, construction, and management organization with over 1,400 employees in architectural, engineering, construction, and facilities management, the company's tenants include names like Bellsouth, AT&T Wireless, Coca-Cola, Dover Elevator, Dun & Bradstreet, and Serta.
Koury's vice president of facilities management, Gene Greer, is responsible for the maintenance of all the company's properties with the primary goal of reducing operating costs. He wanted to keep the company's tenants comfortable and also reduce service calls, and he decided to try thermally powered VAV diffusers. After using them in several buildings, he also found that they drastically reduced service calls. Now, his data for the last three years confirms lower HVAC maintenance costs of more than 20% for a building with thermally powered VAV diffusers over a similar building with part constant volume and part VAV box systems.
