Abstract

Presently, the average temperature in Thailand is tended
to be increasing every year. Many organizations, therefore, create
energy-saving campaigns to decrease energy consumption in
buildings, for example, reduce unnecessary energy use, turn off all
lights and switch off all electrical appliances when not in use, and
reduce heat transfer in buildings. Reducing heat transfer in buildings
is one of the energy-saving strategies that can decrease energy
consumption. To study energy reduction by this strategy, this research
aims to analyze Overall Thermal Transfer Value (OTTV) and Roof
Thermal Transfer Value (RTTV) of a two-story commercial building.
Construction materials data of the commercial building, such as
walls and roofs, including temperature inside and outside of the
commercial building, are collected to examine the study. According to
the research, averages of OTTV and RTTV are 80.36 W/m2
and 59.18
W/m2
subsequently, which are higher than the standard values specified
by the Ministry of Energy. By this, the commercial building would be
needed for renovation in order to meet the standards. Adding insulation
and gypsum board to wall, applying window tinted film, and attaching
insulation and insulated ceiling to the roof can help to decrease the
averages of OTTV and RTTV about 57% and 80% respectively. The
outcomes from this research could be applied for the energy-efficient
renovation of buildings in the future.
