  • 2. Integrated Design Approach 15 June 09 Environmental Design Solutions Sustainable Development Partners Building Owners Builders/Contractors Manufacturers Architects/Engineers Building Users
  • 3. Integrated Design for Sustainability 15 June 09 Environmental Design Solutions
  • 4.
    • Energy
      • Performance Targets for Buildings:
    • Optimised orientation
    • Micro-climate control to avoid heat Island
    • Daylighting (>90% Daylit spaces)
    • 100% shaded Glazing during summer (April-October)
    • Natural ventilation Potential in transition spaces
    • Minimal Heat Gain through building envelope (50% better than ASHRAE 90.1 2007 an ECBC envelope standards)
    15 June 09 Environmental Design Solutions
  • 5.
      • Performance Targets for Buildings:
    • Compliance check with ECBC for the following:
      • Envelope
      • Lighting
      • HVAC systems
    • District heating and Cooling system
    • Energy Efficient External and Internal lighting
    15 June 09 Environmental Design Solutions
    • 1. Illuminance Levels
      • As per NBC 350 Lux average
      • Lighting Load (<0.7 W/sft for offices)
      • Suspended direct indirect light fittings
      • Desk and furniture mounted task light
  • 6. 15 June 09 Environmental Design Solutions
      • Performance Targets for Buildings:
    • Comfort Conditions
      • 27C cooling set point (Japan has mandated this)
      • Integrating Ceiling Fans with HVAC for improved comfort
    • HVAC Load
      • 400+ sft/TR
      • HVAC equipment efficiencies to exceed the ASHRAE 90.1 2007 Standards
    • Equipment Use and Electrical Load
      • Reduce energy use for computers
      • Flywheel based UPS
    • Overall energy use can be as little as than 90 kWh/m2/year
  • 7. Renewable Energy 15 June 09 Environmental Design Solutions
    • Carbon Neutral (through on site + off site energy)
      • Zero Net Energy for Lighting (through On-Site generation)
          • PV systems integrated in design
          • Micro/ Macro Wind turbines
          • Biogas/Biomass (Kitchen waste + STP output + landscape Waste)
    • Positive Life Cycle cost of all investments
          • Energy Systems (Except renewable to have a payback of less than 5 years
  • 8.
    • Water
    • Water use reduction –Efficient and low flow
    • water fixtures
    • 100% rooftop Rainwater Storage & Recycling
    • Surface rainwater to be filtered and sent to aquifer
    • 100% STP water to reused on site
    15 June 09 Environmental Design Solutions
  • 9.
    • Waste
    • Minimise waste production by awareness
    • programmes
    • Dedicated, easily accessible and adequate
    • communal waste storage areas
    • Zero Waste
      • During Construction
      • Post construction, Construction waste management plan to be implemented
        • Waste collection and segregation at source
        • Treatment of Organic waste on-site
        • Rest including e-waste to be sent for off-site recycling
    15 June 09 Environmental Design Solutions

  • 13. Energy Efficiency Impact 15 June 09 Environmental Design Solutions
    • Renewable Energy onsite ~ 1.2 MW
    • This will reduce the grid energy use of the project further by 6-8%
    • Resulting in total energy savings of 45-47% over the ASHRAE 90.1 2007 baseline
    • Server room energy use is also optimized to match the overall building savings level
    • Total energy savings ~ 8 million kWh/year
    • ~ 7000 Tons of CO2 emission avoided directly
