An Energy and Peak Loads Analysis of the TYC/TRC Building – Final Report
MetadataShow full item record
The energy use of the Texas Youth Commission/Texas Rehabilitation Commission (TYC/TRC) Building at Austin, Texas, was analyzed using the DOE 2.IB 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 energy consumption of the TYC/TRC Building can be reduced with certain modifications.
DescriptionThree options for reducing the building energy use were studied: (i) a variable air volume system (VAV) with a variable speed fan and economiser cycle instead of dual duct variable volume (DDV) system, (ii) modifying the building to comply with the ASHRAE standards and (iii) modifying the building to comply with the California standards. These options not only reduce the peak loads but also reduce the total energy use. The energy consumption of the TYC/TRC Building was compared with the energy consumption of the building modified to comply with the ASHRAE and California standards. A net reduction of 38% and 44% was obtained using the ASHRAE and California standards, respectively. The California standards are more stringent and are a better choice for state owned buildings which have a life of 30 to 40 years.
