| Summary: | This field investigation of
thermal comfort parameters in Green Building Index (GBI)-rated office buildings
employing various façade-shading devices compared thermal performance in terms
of four main variables: indoor air temperature, indoor relative humidity, mean
radiant temperature, and indoor air velocity. Over five days of fieldwork at
each building, the four variables of interest were measured, recorded, and
analysed using Excel graphs. The results show that the thermal comfort
performance of each building was acceptable within the parameters of the GBI
Non-Residential New Construction (NRNC) Tools for Indoor Environmental Quality
(IEQ). In general, observed values were good for three of the four thermal
parameters: indoor air temperature, indoor relative humidity and mean radiant
temperature. However, indoor air velocity fell below the acceptable range as
defined by the GBI NRNC Tools. One possible reason for this negative outcome is
low air exchange from the air conditioning systems in the selected buildings. |
