While mechanical energy codes may lag relative to the efficiency targets of some other codes , the expansion of VRF into a wider range of equipment makes it easier than ever to exceed expectations. Perhaps more importantly, its incorporation into heat pumps, dehu-midifiers, compressors, and more represents more flexibility in delivering an effective retrofit without a total system overhaul.
In theory, a BAS provides all of the hardware and software required to analyze and operate all functions within a building. In reality, though, what most of these systems do best is control the HVAC system.
Seven questions to always ask the existing boiler’s operator round up this article, written to save you time and save your client grief (and possibly money) before, during, and after the project. Pumps, pipes, asbestos, and budget are just a few areas where opportunity (or problems) await.
Leaning on experience and data from various K-12 cities and projects, the author pursues some less conventional design approaches. They may revolve around radiant heating and/or cooling, but depending on school size and other factors, the smart use of heat recovery, DOAS, and improved central plants could also put a project on the HVAC honor roll.
