is a graph showing the energy consumption according to the window area ratio of 50% and the glass performance in Seoul.
As you can see from the picture, the glass performance is normal
As it increases to low-e glass and low-e + argon glass, the amount of cooling energy decreases by 0.12% and 0.02%, but the heating energy is 1.34% and 0.45%. Appeared. It was found that the heating energy was affected more than the cooling energy by the glass performance, and the total energy consumption per unit area decreased as the glass performance increased.
Cooling energy is triple window, low-e + argon glass, SHGC 0.2
At 134.55 KWh/ m2yr, it is the smallest, and the triplet, Low-e + argon glass, SHGC 0.8 at 144.92 KWh/ m2yr, the largest. Heating energy is triple window, low-e + argon Glass, SHGC 0.8 was the lowest with 178.09 KWh/ m2yr, double glazing, ordinary glass, and SHGC 0.2 was the largest with 193.75 KWh/ m2yr. This means that cooling energy is more than heating energy.
The more the glass performance increases, the more it is affected by SHGCYou can see that
Comparison of energy consumption according to SHGC and window area ratio (normal double-layer window, air layer 12mm)
