GREEN BUILDING

Green Building  Green Building does not refer to building which are green in colour or have been constructed with green parks around. It refers to a conscious practice of addressing the issue of resource conservation in an integrated and scientific manner. By definition, a green building is one which uses less water, optimizes energy efficiency, conserves natural resources, generates less waste and provides healthier spaces for occupants, as compared to a conventional building. Modern-day building have a tendency to use designs and materials which are resource-intensive and are quite often operate in isolation with the nature. Such buildings are very poor in energy efficiency and generate a lot of waste, adding to faster depletion of natural resources. Thus, building are seen today as one of the major pollutants to affect urban air quality and contribute to climate change. GREEN BUILDING A green building depletes very little of the natural resources during its construction a

SOLAR Energy

The visible and near visible (Ultra-Violet and near Infrared) electromagnetic radiation that is emitted by the Sun is termed as Solar Radiation . The solar radiation has a spectral or wavelength, distribution that corresponds to different energy levels, short wavelength radiation has a higher energy than long wave length radiation. These solar radiation convert into useful forms of energy such as "heat and electricity", using a variety of technologies. The technical feasibility and economical operation of these technologies at a specific location depends on the available solar radiation or solar resource. Photovoltaic Effect :- Photo-voltaics are the technology for conversion of solar radiation (sunlight) directly into electricity. A photo-voltaic cell also called a PV or a solar cell is the device used for this purpose. The PV technology has  emerged as a promising technology to generate electricity for small applications like lighting and meeting other electric
