Wireless Sensors: Technology and Cost-Savings for Commercial Buildings
Two projects under way for the U.S. Department of Energy Office of Building Technology, State and Community Programs, aim to adapt, test and demonstrate wireless sensors and data acquisition for heating, ventilating, and air-conditioning (HVAC) in commercial buildings. One project focuses on built-up systems in medium to large buildings; the second on applications for rooftop units in small- to medium-size facilities. In this paper, the authors present the technical characteristics and costs of off-the-shelf wireless sensor and data-acquisition systems and describe how they can be adapted to commercial buildings. The first part of the paper discusses the appropriateness of the different wireless protocols and then uses a "low-cost" and "high-cost" scenario later in the paper for comparison to wired systems. The paper provides a brief overview of wireless communication standards and discusses their appropriateness to HVAC control applications. The authors describe two wireless technology demonstration projects and discuss the limitations of today's technology and how wireless technology might be improved to reduce costs. Finally, a cost comparison between wired and wireless control networks for retrofit and new construction is presented to provide insights into the key drivers that determine the cost competitive of wireless technologies for HVAC control applications.
