The aim of this study was to investigate the effects of windows and building
envelope materials on the thermal performance of residential buildings, for
the climatic conditions of Ankara.
The effects of the thermal mass of the building envelope, together with the
effects of glazing type and shading conditions of south-facing windows on
thermal performance were investigated using two computer-based thermal
analysis programs called: ECOTECT 5.0 and ENERGY-10. The
hypothetical building model used for computer simulations was based on the
sample residential building defined in the Turkish Standards on the
Regulations for Building Insulation, TSE 825, as prepared by the Tü / rk
Standartlari Enstitü / sü / (TSE, Turkish Standards Institute). Simulation studies
were first conducted with ECOTECT 5.0, but since the results did not
conform to earlier researches and, since this discrepancy could not be explained even by the support forum prepared by the authors of this
software, it was decided to continue the simulations with ENERGY-10, which
proved to be more consistent. The results of 240 program runs of ENERGY-
10 were explained through graphical and statistical analysis on the basis of
annual heating, cooling, and total energy needs of the building model.
The study showed that building envelope materials having high thermal
storage capacities together with high-performance glazing, in terms of
increased thermal resistance, provided significant energy savings, which
could be augmented by increasing the size of south-facing windows. The
study also revealed that shading devices in the form of fixed overhangs
applied to a south-facing window of any size did not provide substantial
reductions in the energy demands of residential buildings, when annual total
energy demands were considered for the climatic conditions of Ankara.
