Development and Analysis of a Sustainable Low Energy House in a Hot and Humid Climate
MetadataShow full item record
This study examines the lifetime building energy consumption of a typical house in Bangkok, Thailand. The lifetime building energy consumption is composed of three major components: 1) the energy used in building construction (i.e., embodied, transportation and construction energy), 2) the energy used in building operation (annual energy), and 3) the energy used in building demolition (demolition energy). The study used measured environmental and energy use data from a case-study house in Thailand. For the construction energy and the energy used in building demolition analyses, reference data from reliable sources both in the U.S. and the U.K. were used. The DOE-2 energy simulation program was used to analyze changes to the annual energy use caused by changing various building materials and/or design configurations. A new energy efficient design was then iteratively chosen that contained reduced levels of embodied energy use and reduced annual energy use. The results from the analysis showed that the total lifetime energy use was reduced from 3,974 to 2,773 MMBtu (a 30% reduction). This was accomplished by replacing energy intensive materials with less energy intensive materials that were also energy efficient, namely the masonry walls. The addition of insulation in the ceiling and energy efficient windows was also included.
