THE EFFECT OF BALCONY THERMAL BREAKS ON BUILDING THERMAL AND ENERGY PERFORMANCE
There is very little research on the impact to building
energy thermal comfort performance from nonthermally
broken balconies. Balconies are a common
feature of many high-rise buildings. They are exposed
portions of the floor slabs, which, unlike the rest of the
building envelope, are not thermally insulated. Building
codes are somewhat ambiguous with how to treat
balconies for thermal protection. Because of that,
balcony slab connections act as large thermal bridges
that cause excessive heat loss and gains from and to the
interior space and poor indoor thermal comfort. This
paper introduces the results of a research study that
evaluated the effect of insulated thermal breaks in
balconies on the envelope thermal performance and the
overall building energy performance using an
experiment and a parametric energy analysis.
