| Abstract | This study investigates feasibility of energy conservation options for a new building in
ATT. The study first compiles energy audit information of twenty-five existing buildings in
Thailand. They are classified as hotels, depaitment stores, hospitals and office buildings. The
results from the energy audit are used as reference for forming a model for the building. The
computer simulation program used as a tool for prediction of energy consumption is DOE-2 of
the U.S. Department of Energy which was developed by the Lawrence Berkeley Laboratories.
Three categories of alternative options are analyzed. The first category encompasses
building envelope. Second and third cover lighting and air conditioning system respectively.
Results of the DOE-2 simulation of each retrofit option are used to evaluate teclmica l and
economic feasibility in term of the energy saving and cost.
For building envelope, the different wall, window and roof compositions are used in
DOE-2 simulation and costs I benefits are compared.
For lighting system, standard, low-loss ballasts and electronic ballasts are used and use
options to compare with daylighting integrated with automatic continuous linear dimming
control system.
For air conditioning system, Two-Pipe Fan Coil (TPFC) system for base case is
compared with Variable Air Volume (VAV) system and Cold Air Distribution (CAD) system
in the study.
The most attractive alternative of each category is used in the fina l investigation. The
results indicate that the combination has high potential for energy saving both in terms of
technical and economic points of view. Its pay-back period is only 2.65 years. While its net
present value is high at 282,410 Baht and the internal rate of return is at an acceptable level of
37.62%. |
