Financial Benefits and Overall Costs of Green Buildings Essay
Waste management is an important factor in sustainable building. If waste is not managed, it becomes costly for a construction project. The sustainable way of building encourages practices such as waste prevention, salvage, deconstruction and recycling to reduce waste management costs. Transportation and landfill costs could add to a project cost, however green building eliminates these costs through the applying of the practices above. (Fishbein, 1998) Construction waste generally makes up to 10% - 30% of the waste received in landfill sites around the world. Among other benefits, purchasing costs are reduced for the project since some materials are being recycled and reused.
According to Gregory Kats, looking at energy costs, the average green building uses 30% less energy than conventional buildings (Kats G.H, 2010). On top of this energy efficiency, green buildings are likely to generate renewable energy on site and they have lower electricity peak consumption. The self generated energy comes from photovoltaic.
