Bells and Whistles, or Just Plain Effective? The New Generation of Wireless Controls in Existing Commercial Buildings.

Abstract

Wireless controls are a key feature for improving the energy efficiency of existing commercial buildings. But what impact do they really have on building performance? This paper provides three case studies to explore the costs, benefits, and relevance of this technology in the existing building market. Many of the nation's millions of small to mediumsized commercial buildings do not have building automation systems. The reluctance to install controls has historically been linked to the high cost of wiring buildings for such systems. However, new wireless technology is relatively simple and more affordable, allowing owners to reduce maintenance costs, save energy, and improve occupant comfort. Wireless systems enable the facility manager to monitor and control multiple buildings from almost any location via a smartphone or computer. Not only do these new controls allow optimal scheduling and locate potential problems, they also enable a resolution to issues before a complaint is received.
