Heat performance measurement is purpose within 3 cases, the building without coating, with
conventional coating color and with high solar reflective paint (Beger Cool Ultra Violet Shield). In
each case, the color was applied on the outer walls and using two shades of color namely white and
white grey color (except the first case). The heat performance, the effect from the outside heat load
which receives from solar radiation through the buildings to the air conditioner in each buildings was
investigated (be not interested in inside heat load). When the walls and roofs receive solar radiation,
the temperature difference befween inside and outside are produced that cause of the heat transfers to
inside buildings. From this result, air conditioner load was built. Thus, the important parameter of this
research is the temperature both inside and outside buildings in order to determine the heat load that
transfers through inside buildings. Measurement temperature within building is carried out using a
data logger with an accuracy of + 1 oC connected to 1 mm-diameter, type-K thermocouples cable that
calibrated with ASTME 220-07a by comparison with reference thermometer.
