- 8. THE BRITISH SCHOOL Thefollowing strategies were adopted to reduce the building impact on the natural environment: Sustainable Site Planning: • 5 trees existed on site and all were preserved. In addition, the project planted 292 native trees to enhance microclimate of the area. • Air pollution control measures such as site barricading, coverage of dusty material, wheel washing and water sprinkling were implemented during construction.

The Watershed's mission includes stewardship of the land, advocacy, education, and research on water related environmental issues. • The geometry of the new building incorporates an existing house and forms a central garden courtyard with series of features intended to convey the role of water and the hydrological cycle. • These include an evacuated tube solar hot water array, used as a sunscreen, a linear green roof, a rain garden, and an elaborated roof scupper that focuses a cascade of water on locally quarried stone. • Other water features include rain water harvesting tanks, bioswales, a constructed wetland wastewater treatment system, and a geothermal system. Water throughout the complex is monitored and depicted in educational exhibits.
- 12. The platinum certifiedbuilding features on site renewable energy with • a roof mounted solar array and electric heat pump system. The Center is expected to be close to energy net zero performance. It received five out of five credits for innovation in design and 31 of 35 credits in Energy and Atmosphere. • Its materials include FSC certified wood, cypress siding, exposed aggregate concrete, and cellulose insulation. • The interior of the building has been carefully modeled for daylight performance, with windows placed in clerestory and north locations to naturally light galleries, classrooms, and laboratory.

Sustainable Site Planning Water Management Energy Optimization &Occupant Comfort Sustainable Building Materials Innovation UGBC - LEED STONY BROOK MILLSTONE WATERSHED ASSOCIATION • Site strategies included a reduction of lawn area, introduction of meadow and native species with no irrigation requirements, new bioswales in existing parking and provision for alternative transportation modes. • The building materials are extensively composed of recycled and sustainably produced products, with recycled steel, exhibit cases and casework, FSC cypress, cotton insulation, and acoustic treatment. • These include an evacuated tube solar hot water array, used as a sunscreen, a linear green roof, a rain garden, and an elaborated roof scupper that focuses a cascade of water on locally quarried stone. This last feature makes visible the impact of precipitation, surface runoff, and recharge, and reiterates the mountain and valley topography of this landscape. • The geothermal heat pump system does not use fossil fuel and is supplemented by an evacuated solar tube system that provides domestic hot water. • Demand control ventilation and operable windows provide natural ventilation. • Special consideration had been given to natural lighting in place of electric lighting, with roof monitors providing reflected light into significant program spaces. • A high performance envelope with green roof, high U-value insulation, and building orientation minimizes energy requirement. • The building materials are extensively composed of recycled and sustainably produced products, with recycled steel, exhibit cases and casework, FSC cypress, cotton insulation, and acoustic treatment. • The 44 inches of annual rainfall has to be managed with a variety of demonstrable strategies including green roof retention, a collector and cascade roof structure that recharges through a rain garden, rain barrels, cistern for greywater use, an open loop geothermal system and an innovative constructed wetland system that features tertiary effluent treatment through natural processes.

- 18. Water Management Sustainable Building Materials Innovation RURAL- VERNACULAR GOVARDHAN ECO VILLAGE •Hydrogeological study provided us with clear recharge and discharge zones suggesting the extraction pattern with respect to quantity available. This was the basis for the overall site planning with respect to buildings, services and roads. • With on-site treatment of waste water, nutrient rich water is now available throughout the year and food is grown even in summer months. • As the location was far from manufacturing base the site was mapped for availability of earth for making of buildings and through expert skill transfer the future constructions are possible. • The ponds and water bodies were made in the areas where soil was suitable for earth construction. • The key feature of this project is the use of stabilized mud bricks and CSEB ‘U’ Blocks. Other sustainable materials used here include CSEB tiles, timber and bamboo. Mangalore tiles dominate the roof of the whole project scheme. • Various approaches to use of earth as construction material has been tried here and different techniques are employed depending upon the use of the space and the skill of the builder. • Through introduction of precast construction, U- Block lintels, and standardization of building elements like arches and windows speeded the construction process thereby reducing the of construction. • The first phase was built using skilled masons from Bangalore. In the subsequent phases, the local mason’s picked up the skills of using alternate technologies and are now working on projects outside of GEV, using these technologies.
