GREEN BUILDINGS.  DEFINITION: "A green building is one which uses less water, optimises energy efficiency, conserves natural resources, generates less waste and provides healthier spaces for occupants, as compared to a conventional building."  GREEN BUILDING: Green building is also known as green construction or sustainable building. It refers to a structure and using process that is environmentally responsible and resource- efficient throughout a building's life-cycle.  ADVANTAGES: Efficiently using energy, water, and other resources. Protecting occupant health and improving employee productivity. Reducing waste, pollution and environmental degradation.  Goals of green building:  Trigger investments in energy efficiency and renewable energy technologies in non-residential buildings.  It wants to initiate energy efficiency investments in non- residential buildings which are clearly profitable and are based only on proven technologies.  contributes to the advancement of the present state-of-the-art in energy saving techniques.  SITING AND STRUCTURE DESIGN EFFICIENCY: The foundation of any construction project is rooted in the concept and design stages. In designing environmentally optimal buildings, the objective is to minimize the total environmental impact associated with all life-cycle stages of the building project  Energy efficiency: Green buildings often include measures to reduce energy use. By using high- efficiency windows and insulation in walls, ceilings, and floor. By using Solar water heating further reduces energy loads.  Water efficiency: Reducing water consumption and protecting water quality are key objectives in sustainable building.  Materials efficiency: Building elements should be manufactured off-site and delivered to site, to maximise benefits of off-site manufacture including minimising waste, maximising recycling (because manufacture is in one location), high quality elements, less noise and dust.  Operations and maintenance optimization: No matter how sustainable a building may have been in its design and construction, it can only remain so if it is operated responsibly and maintained properly. It is easy to maintenance.  Waste reduction: Green architecture also seeks to reduce waste of energy, water and materials used during construction. For example, in California nearly 60% of the state's waste comes from commercial buildings.  Cost and payoff: The most criticized issue about constructing environmentally friendly buildings is the price. Most green buildings cost a premium of
