Abstract
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.
Description
Three 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.
