DescriptionThe energy use of the Department of Health Building at Austin, Texas, was analyzed using the DOE 2.1B building energy simulation program. An analysis was made for the building as specified in the building plans and the specifications provided by the State Purchasing and General Services Commission. Operating schedules for occupancy, lighting, office equipment, and infiltration were assumed. The proposed construction of the Health building reflects improvements in energy use over buildings built several years ago (EUIs of 142 Kbtu/sf/yr compared to as much as 250 Kbtu/sf/yr). However, the energy consumption of the Health building can be reduced with certain modifications. Four options for reducing the building energy use were studies: (i) reducing the lighting levels, (ii) reducing the ventilation rate from 20 cfm/person/hr to 10 cfm/person/hr (iii) having a variable speed fan with the VAV system and economiser cycle and (iv) improved glass. These options not only reduce the peak loads but also reduce the total energy use. Finally the energy consumption of the Health building was compared with the energy consumption of the building modified to comply with the California standards.A net reduction of 44% was obtained using the California standards. The California standards are more stringent and are a better choice for state owned buildings which have a life of 30 to 40 years.
