solar panels.
Able to screen and reduce sunlight from direct exposure Both heat gain and ventilation issues can be solved to provide shade and cooling
introduction of double glazed windows.
low - e glass. to reduce solar heat gain.
Applied to windows help block infrared light from penetrating the glass to maintain thermal comfort of room temperature and improve energy efficiency
Change to Low-E Glass glazing to reduce solar heat gain
Panel systems certified by SEDA Malaysia 80%
Able to fully capitalized as Malaysia s climate is sunny all year round
Potential to save up to 80% of electricity
Reduce carbon footprint
Slanted roof exposes it to sun, allowing it to constantly gain energy
Excess energy can be sold back to TNB improved mechanical ventilation. inverter air conditioner.
Low-E Glass UValue of 0.26 Wm2K is lesser than normal glass of 1.2 Wm2K 22%
[ non-inverter unit. ] monthly power consumption = 0.91 kWh/hr x 250hrs
= 227.5 kWh cost / month = RM 52.80 / unit
[ inverter unit. ] monthly power consumption
= 0.86 kWh/hr x 250hrs
= 215 kWh cost / month = RM 48.6 / unit cost difference consumption of energy saved by :
= RM 52.80 - RM 48.6
= RM 4.20 / unit
