Abstract


Better roof insulation helps in reducing heat intake and results in energy efficiency. Similarly, Light Colored Roofs absorbs less heat resulting in reduced energy consumption for air-conditioning thus achieving energy efficiency. These two combined effects can be achieved through a composite material of Sawdust White Cement Concrete. Sawdust is a waste material of sawmills and wood working factories. Sawdust used with white cement for having a lighter color, lightweight and better insulation can be used for achieving energy efficiency in Green Buildings and reducing urban heat island effect as the lighter color and better insulation will absorb lesser heat thereby radiating lesser heat after sunset.

In cities with lots of high-rise and other structures, one feels waves of blistering heat emanating from dark buildings. Past nightfall, one can notice buildings still radiating heat where as surrounding rural areas are rapidly cooling. Almost every city in the world today is hotter than its surrounding area. During hot months an urban heat island creates considerable discomfort and stress thus increases air-conditioning loads. Research shows that for every degree of increased heat, electricity generation rises by 2% to 4 %. Through efficient selection of building materials and roof insulations one can reduce the air-conditioning loads and achieve energy efficiency. The paper will deliberate over efficient use of resources, energy efficiency and usage of waste material as building construction material in Green Buildings.

Key Words: Green buildings, Energy Efficiency, Roof Insulation, Usage of Waste Material
