"A building whose walls or roofs are independent of any other building with open space on all the sides is called detached house". e.g. Residential Bungalows. This type of construction of dwelling houses is very popular in India, but this is possessed by higher / middle income group of families. "The two/twin detached house connected with one common wall is called semi-detached house" as shown in Fig. These houses have open space on three sides. e.g. Bungalows in agriculture zone. Detached houses are constructed in one row with one common wall between two houses are called row-house These type of houses are very common in India. Staff Quarters in public sectors, industries etc. This is a sort of row houses or terrace house with common services like W.C. bath, staircase, lifts and passages etc. e. g. Hostels, dormitories etc. Location: It should be do located that sufficient light and ventilation should be ensure stairway Width of stair: for public building= 1.5 to 2.5m, residential building= 0.9 to 1.5m Pitch of staircase: The slope of stair should not be greater than 40 degree and should not be less than 25 degree. Headroom: The vertical distance from a line connecting the nosing of all treads and the soffit above. The head room measured vertically above any step or below the mid landing shall not be less than 2.1 m. Tread: Horizontal upper portion of a step where the foot is rests is known as tread. For residential building (T) 220mm to 250mm and for public building 250mm to 300mm. Rise: Vertical distance between two consecutive treads. Rise is depends on type of building and the value varies 200mm to 300mm. Flight: A series of steps provided between two landings. Minimum air conditioning land Lighting power density Power consumption Better indoor air quality Visible light transmittance Water conservation Rain water harvesting system Rich flora and fauna Recreation areas for children’s and adults Minimum excavation of water from environment Buildings have great impact on environment, human health and economy. Reduce waste streams. Improve air and water quality Conserve and store water resources Enhance and protect biodiversity and ecosystem Create, expand & shape markets for green product and services Cost of working & construction decreases Productivity of occupant increases The cost of green buildings are more than standard buildings Minimize pressure on local infrastructure Height aesthetics quality Improve life quality Enhance occupant comfort and health Site planning. Building envelope design. Building system design. Insulation of building Window shading & sizing Wind towers for pre cooling of fresh air Selection of glass Heating ventilation and air conditioning (HVAC). Lighting, electrical, and water heating. Integration of renewable energy sources to generate energy onsite. Water and waste management. Selection of ecologically sustainable materials. Indoor air quality (maintain indoor thermal and visual comfort, and air quality). The orientation of green building should be constructed is the position of the building on the site selected for the project with respect to the sidewalks, the roadways, and the landscaping features. 25% energy can be save is proper orientation of building is done. To provide a comfortable living space in a building in any climatic condition, orientation plays an important role. Under hot and dry climatic condition, the orientation of a building should be- Hot and dry climatic zones: In day max summer temperature goes as high as 45 degree centigrade and relative humidity as low up to 20 %.In this type of climate areas far from sea coasts and do not receive heavy rainfall so the humidity is very low. In this climatic zone building should be orientated based on solar point of view so that during winter season building receives maximum solar radiation and minimum during summer season. It is a voluntary, market driven program that provides third party verification of green buildings. LEED is the most widely used green building rating system in the world. Derived in 1998. From individual buildings and homes, to entire neighborhood and communities, LEED is transforming the way built environment designs, constructed and operated. Comprehensive and flexible, LEED addresses the entire life cycle of building. It provides building owners and operators with a framework for identifying and implementing practical and measurable green building design, construction, operation and maintenance solutions. Design methodology that encourages the participation of all project team members through all phases of the project. Many LEED credits require co-ordination and co-operation between all disciplines.
