3 What is green building Green building, or sustainable design, is the practice of increasing the efficiency with which buildings and their sites use energy, water, and materials, and reducing building impacts on human health and the environment over the entire life cycle of the building. Benefits Tangible benefits - include reduction in water and energy consumption right from day one of occupancy. The energy savings could range from % and water savings around 30-50%. Intangible benefits - enhanced air quality, improved day lighting, health & well being of the residents, safety benefits and conservation of scarce national resources. Green Homes rating system can also enhance marketability of a project..and yes, it helps you save money too

7 SITE SELECTION AND PLANNING

8 SITE SELECTION AND PLANNING Adhering to Local Building regulations (Mandatory) Ensure that the building(s) complies with necessary statutory regulatory codes. Prevention of Soil Erosion and Sedimentation (Mandatory) Control Soil erosion and sedimentation thereby, reducing negative impacts to the site and surroundings. Community Connectivity / Basic Amenities Reduce negative impacts caused to the environment from automobile use by providing basic house hold amenities, thereby, enhancing the quality of life. Parking capacity Provide adequate parking within the site to minimize disturbance caused due to parking on public roads, thereby enhancing the quality of civic life. Electric Charging Facility Encourage the use of electrical vehicles thereby reducing negative impacts resulting from fossil fuel based automobile use.

9 SITE SELECTION AND PLANNING Heat island effect Roof & Non Roof 50%,75% Minimize disturbances to the site so as to reduce longterm environmental impacts. Reduce heat islands to minimize on microclimate, human and local bio-diversity. Natural topography or Vegetation 15%, 25% Minimize disturbances to the site so as to reduce longterm environmental impacts. Basic Facilities for Construction Workforce Ensure Promote welfare of construction workforce by providing safe and healthy work conditions. Design for Differently Abled Ensure that the building/campus design cater to differently abled people. Green home guidelines, design & post occupancy Provide prospective buyers and residents with descriptive guidelines that educate and help them implement green design features.

10 WATER EFFICIENCY

11 WATER EFFICIENCY Low Flow Fixtures (Mandatory) Enhance ground water table and reduce municipal water demand through effective rain water management. Rain Water Harvesting 25% (Mandatory) Enhance ground water table and reduce municipal water demand through effective rain water management. Treatment and use of Waste water 50% Reduce consumption of potable water and waste water generation to minimize the burden on municipal water supply. Efficient Irrigation systems Reduce water demand for irrigation through water efficient management systems and techniques.

12 WATER EFFICIENCY Landscape Design - Design landscape to ensure minimum water consumption Reduce turf area Native adaptive species Plant bed segregation Water Metering Encourage continuous monitoring to enhance water performance in the project

13 ENERGY EFFICIENCY

14 ENERGY EFFICIENCY CFC free Refrigerants (Mandatory) Avoid use of refrigerants and ozone depleting gases which has negative impact to the environment. Building Energy Performance (Mandatory) Improve energy efficiency of the building(s) to reduce environmental impacts from excessive energy use Enhanced energy performance Improve energy efficiency of the building(s) to reduce environmental impacts from excessive energy use. Selection of energy efficient equipment Conserve energy in the use of house-hold appliances and other equipment, thereby reducing environmental impacts. Renewable energy 2.5% onwards Promote self sufficiency in energy through renewable technologies for on-site power generation and use within the project.

15 ENERGY EFFICIENCY Distributed power generation Reduce dependence on fossil fuels for in-situ power generation. Solar water Heating 25% Encourage use of solar energy for water heating applications in the building(s). Energy metering Encourage continuous monitoring to enhance the energy performance in the project.

16 MATERIALS AND RESOURCES

17 MATERIALS AND RESOURCES Waste Segregation (Mandatory) Facilitate segregation of house-hold waste at source so as to prevent such waste being sent to land-fills. Organic Waste Management 50% Ensure effective organic waste management, post occupancy, so as to prevent waste being sent to land-fills. Construction waste management 50% Encourage practices to manage construction waste, thereby, avoiding waste being sent to land-fills. Reuse or salvage Materials 1% Encourage the use of salvaged building materials and products to reduce the demand for virgin materials, thereby, minimizing the impacts associated with extraction and processing of virgin materials.

18 MATERIALS AND RESOURCES Recycled Material 10% Encourage use of materials which contain recycled content to reduce environmental impacts associated with the use of virgin materials. Local Materials 25% Encourage use of building materials available locally, thereby, minimizing the associated environmental impacts resulting from transportation. Certified wood and rapidly renewables 50% Minimize use of virgin wood, thereby, encouraging responsible forest management and maximize use of materials which are rapidly renewable.

19 INDOOR ENVIRONMENTAL QUALITY

20 INDOOR ENVIRONMENTAL QUALITY Tobacco smoke control (Mandatory) Minimize exposure of non-smokers to the adverse health impacts arising due to passive smoking, post occupancy. Day-lighting Minimum, Glazing factor 50% (Mandatory) Ensure connectivity between the interior and the exterior environment, by providing adequate day lighting. Fresh air ventilation (Mandatory) Avoid indoor pollutants affecting indoor air quality by providing adequate outdoor air ventilation based on stated design criteria. Low VOC material Encourage use of materials with low emission so as to reduce adverse health impacts on building occupant.

21 INDOOR ENVIRONMENTAL QUALITY Exhaust systems Ensure that kitchens and bathrooms are adequately ventilated, so as to improve the quality of indoor Environment. Building flush out Avoid occupant s exposure to indoor airborne contaminants before occupying the premises, So as to reduce the adverse health impacts on building occupants. Cross Ventilation (50-75%) Encourage adequate cross ventilation in the design thereby, providing a healthy environment.
