Green features We find that the purpose with which the GBC was built is perhaps even more important than various green techniques and concepts used for its actual construction, so we concentrated more on the functions it performs; we are describing the green features incorporated in it only briefly. Site planning GBC is built on a huge site that gave the designers ample opportunities to set their own rules. The structure is centrally located on the flattest part of the site. This allowed the developers not to interfere with the site features during construction.

Importance of Green Buildings The growth and development of our communities has a large impact on our natural environment. The manufacturing design construction and operation of the buildings in which we live and work are responsible for the consumption of many of our natural resources.
The green concepts and techniques in the building sector can help address international issues like water efficiency reduction in fossil fuel use for commuting handling of consumer waste and conserving natural resources.
Jain Mr. It offers advisory services to the industry in the areas of: green buildings energy efficiency water management environmental management renewable energy green business incubation and climate change activities. Site Preservation is very important to minimise the site damage and associated negative environmental impacts.

Architect — Ar. Shading from trees are provided adjacent to the walls which reduces the heat transmitted through the walls because of direct sunlight. One of the most common uses of the wind tower is to cool the inside of the dwelling it is often used in combination with courtyards and domes as an overall ventilation and heat-management strategy. It is essentially a tall capped tower with one face open at the top. This open side faces the prevailing wind thus "catching" it and brings it down the tower into the heart of the building to maintain air flow thus cooling the building interior.
It does not necessarily cool the air itself but rather relies on the rate of airflow to provide a cooling effect. North-Light phenomenon is used so that only light enters inside the building and minimum amount of heat. IBMS is used to reduce the wastage of electricity. Figure 11 Naturally Shaded Parking slide 12 Unit-3 Site Selection and Planning Site should be selected for the project considering the safety of occupants and should not disturb the ecosystem.
Project is located in the Hi-Tech City of Hyderabad and has all the basic amenities nearby. Public Transport is very easily available at the distance of m from the location. Use of cycles and battery operated vehicles non-fossil fuel vehicles is promoted and there is a battery charging facility available at the site.
A different parking is available for the people using cycles and battery operated vehicles. Soil Erosion Control and Preservation Figure 12 Honeycomb trays Honeycomb trays are placed in the areas where loose soil is present or there are more chance of soil erosion.
They traps the top layer of soil inside them preventing soil erosion and allowing them to be covered by turf. Top layer of soil was stacked and stored at the time of construction and was again used for the growth of vegetation. There are more than species of vegetation available on site.
Use of native species is promoted as they have more adaptability to the climate and have less water requirement. Heat Island effect is countered at site by using shades from trees grass pavers grid pavers and high SRI tiles on roof and planting vegetation on roof. There is a preferred car park space easy access to the main entrance of the building the main walkways have adequate width and separate washrooms for differently abled.
Figure 16 Ramp for easy access to the main entrance slide 17 Unit-4 Water Conservation Water Distribution in world Less than 1 water on earth can be used by humans which is free from salts and is clean. Survival without water is impossible and it demands to be conserved.
All the buildings and project is designed to harvest most of the rain water. All the pipelines from the roof are well channelled to the rain water harvesting pond. Figure 19 Sprinkler System for turf Project has less than 10 total turf area. Turf area is kept less to reduce the water requirement.
Native species and drought tolerant species are preferred over foreign species as they are have more adaptability to the environmental conditions and they require less amount of water for their growth. Soil moisture sensors are installed which sense the moisture present in the soil and automatically shut-off the water supply.
Waste water treatment and reuse waste water is treated at the site using Phytoremediation technology. Phytoremediation is the direct use of living green plants for in situ or in place for removal degradation or containment of contaminants in waste water.
It can be used to treat any type of contaminant in environmental and climatic conditions. Working A combination of selected species are grown near the septic tank made for storage of waste water. Species used at the site - 1 Filtration Pond a. Parakeet Flower b. Alligator Flag c. Papyrus 2 Polishing Pond a.
Indian Shot b. Powdery Thalia c. Giant Taro slide 20 Water from the input tank is pumped to the roots of plants. Plants grows on a series of pebbles gravels stones and rocks so that their roots can penetrate deep into the ground. A system of pipeline is laid inside the layers through which the water is transferred. This plants treat the water which is then transferred to polishing pond where different species grow. The output water is odour free and suitable for flushing and irrigation purpose.
Water is tested quarterly for proper monitoring. Fly-ash bricks are used for construction instead of clay bricks as they provide better insulation from heat than clay bricks. Roofs are insulated by planting vegetation on it. Wind tower considerably reduce the load on air conditioning system thus saving energy. Figure 23 Wind Tower slide 23 Figure 24 Glazing and High Performance Glass Glazing is used on one side of roof and solar panels are installed on the other side depending upon the orientation of the building.
Around 20 of the total energy requirement of the project are met by onsite solar power production. Figure 26 Superfan Traditional fans are replaced with remote operated superfan which claims to saves more than 50 energy. CFC free Air-Conditioners are fitted with sensors which maintain comfortable temperature inside the regularly occupied spaces.
The building is made up of fly-ash bricks and fly-ash cement which is made up of industrial waste i. There is access of outside view in every room.
