WHY ENERGY EFFICIENCY?
DID YOU KNOW THAT BUILDINGS CONSUMED ABOUT 30% TO 40% OF OUR TOTAL ENERGY?
Research done in Malaysia showed that office or commercial buildings use about 64% of total energy consumed for air conditioning purposes whereas residential buildings used about 35%. With buildings being such big energy consumers here is the opportunity to make them more energy efficient.
Yet many Malaysians are largely unaware of the energy wastage that happens daily in their homes, places of work and entertainment. The rising affluence and higher expectations of comfort also increases demand on energy for cooling.
A model developed by Delft University of Technology called the Trias Energetica shows that energy savings come first as it is the most sustainable energy. Only when a building has been designed to minimise energy wastage, then the focus shift to renewable energy solution like solar energy to reduce dependency on fossil fuels and minimise CO2 emissions.
The technologies to make buildings more energy efficiency such as insulation, shading, glazing, lighting system,etc. are readily accessible, affordable and well proven. One such example is the Ministry of Energy, Green Technology and Water with its Low Energy Office (LEO) building where up to 50% of energy costs is saved with energy efficient measures.
