We describe the measured air-conditioning and thermal performance of a
typical Thai single-family residence. Although the measurements repre
sent a single case study, it is the first time that an analysis has be
en performed on a Thai house with typical modern construction. In such
buildings, the lack of building thermal insulation, the utilization o
f non-ducted air-conditioning equipment and the night-only usage patte
rns are quite different from conditions prevailing in Western-style bu
ildings. Our results show that reduction to ceiling heat transfer in r
esidential Thai buildings is fundamental to improving cooling energy e
fficiency.
