Green Architecture 


Why save energy? The answer of the previous question is quite abroad. It will normally tackle so many environmental aspects associated with acid rain, global warming, air quality and conserving fossil fuels. But most importantly, is dealing with energy in buildings, hence energy consumption in buildings accounts for 45% to 50% of the total energy consumption in most developed countries. Considering the main parameters affecting the energy consumption in buildings will help defining the pattern of energy use, cutting energy costs and thus better energy conscious buildings.



The main environmental burdens are associated with the climate change throughout global warming, acid rain and air quality whether internally (i.e. within buildings) or externally (i.e. outdoor air quality). In this part, mainly global climate change will be highlighted due to its strong relationship with the energy consumption in buildings. Basically, global climate change is caused by emissions of greenhouse gases from fossil fuel combustion. Fuel combustion is a chemical reaction that takes place between oxygen and the fossil fuel (i.e. oil, natural gas and coal) to release heat and a number of gaseous by-products such as carbon dioxide (CO2), sulphur dioxide (SO2), nitric oxide (NO) and nitrogen dioxide (NO2). The latter two compounds are known as nitrous oxides (NOx).



Green Architecture normally complies with the environmentally friendly specifications and standards that maintain healthy indoor environment. Green building practices offer an opportunity to create environmentally-sound and resource-efficient buildings by using an integrated approach to design. Green buildings promote resource conservation, including energy efficiency, renewable energy and water conservation means. Moreover, reducing operation and maintenance costs and creating a comfortable and healthier indoor environment.
