For decades, health care engineers have reported that new building electrical systems are significantly larger than the loads they are intended to serve. This discrepancy has long appeared to be an opportunity for cost reduction. However, something as significant as demand factor requirements in codes changes slowly, and, usually, only in response to overwhelming evidence. This problem has been discussed by organizations such as IEEE, Laurence Berkeley National Laboratories, National Renewable Energy Labs, ASHRAE, and the California Energy Commission. ASHE‘s advocacy team has created a research team to better study and document the realities of this situation and to submit proposals to the National Electrical Code (NEC) in response. That team is now working with representatives of the NFPA to ensure these demand factor adjustments will be approved in the next (2020) edition of the NEC. This session will explore this issue and research in depth, including opportunities for ASHE members to help.
Discuss how the evolution of demand factors for healthcare facility electrical systems have become irrelevant to today‘s health care facilities field.
Explain how new metering technologies for electrical distribution systems are helping inform ASHE and the NEC in ways that will help reduce system oversizing, and ultimately reduce costs so that more resources can be directed at patient care.
Describe ways to be involved in the research and advocacy process to support this important initiative.
Discuss potential design implications with respect to energy consumption of medical equipment and how this helps hospitals provide new and better technology to care for the needs of their communities.
