|Abstract: ||Objectives: This study investigates daylighting condition and cooling effects of a self-shading Energy Commission
Diamond building in Putrajaya, Malaysia, using field measurements. Methods/Statistical Analysis: The field data
were collected using a HD35ED series data logger measuring instrument with a HD35AP base unit. Findings: The results
from the field measurement indicate that illuminance in the building resulting from daylighting alone are above
200 Lux. The average daylight factor is 2.7% which is within the acceptable range of indoor illuminance. From the calculations
of OTTV, it is clearly shown that there is reductions of heat transfer into the Diamond building due to it incline
wall facade that provide self-shading on the building. The average amount of sensible heat energy within the building is
45.8 KJ/Kg, with the west wing and the south wing indoor office spaces having a difference of about 1.5 KJ/Kg in their
enthalpy. On an average, there is a total reduction of 30.6 KJ per unit volume of heat gain into the Diamond building
based on the enthalpy change. Considering occupants comfort and wellbeing in the building, the daylighting requirements
and heat gain in the building are acceptable. Applications/Improvement: This result is an indication that
self-shading in buildings provides efficient daylighting and cooling which in turn reduces the building energy consumption.|
