Abstract
The paper presents the measured results of electricity consumption and cost in a large acute hospital in subtropical Taipei City of Taiwan ROC from August 2001 to July 2002. It was found that air-conditioning is the major electricity end use, accounting for more than 50% of the total building energy use. The highest monthly EUI (Energy Use Intensity) value comes out in July with monthly value of 25.5 kWh.m-2 month-1 and the annual EUI value was 259.45 kWh.m-2 year-1. The highest overall DUI (Demand Use Intensity) vale (45.7 Wm-2) that relates to the electricity contract capacity, appears in August 2001. The highest EUI value found in the region of Operation Theater (OT), in which the EUI value is about three times higher than that in general place. Some approaches to shift peak load are proposed and discussed.
