Goal 1: Reduce Energy Use and Achieve Carbon Neutral

image
  • Measure:  ENERGY STAR Score & Energy Intensity(EUI)
  • Targets:
    • minimally acceptable value: 50 or EUI 121.1 kBtu/sf/yr
    • desired / target value: 75 or EUI 86.0 kBtu/sf/yr
  • Strategies:
    • Lighting Energy
      • reduce artificial lighting: 50%
      • passive daylighting systems
        • to improve the quantity and uniform spread of natural light within a building by capturing and redirecting it to areas with less illumination
          • large windows and crystalline facade
          • panels placed at angles
          • LED lighting and skylights
          • solar shading
    • HVAC System
      • natural ventilation
      • district heating/cooling system
        • heat pumps
        • seawater
    • Renewable Energy
      • Solar photovoltaic (PV) systems
        • capture solar energy for generating electricity
        • at various angles

Goal 2: Reduce Water Consumption and Be Flood-Resilient

image
  • Measure:  percentage of water use reduction
  • Targets:
    • minimally acceptable value:
      • 50% irrigation reduction, 30% fixture use reduction
    • desired / target value
      • 80% irrigation reduction, 45% fixture use reduction
  • Strategies:
    • rainwater harvesting system
      • collect rainwater from rooftops and downspouts
      • create large catchment areas for storage
      • for irrigation, landscaping, indoor non-potable use, and, with appropriate treatment, domestic use
    • greywater reuse system
      • collects, treats, and repurposes wastewater from sinks, showers, and laundry fixtures
      • undergoes filtration and treatment to remove contaminants
      • for irrigation, toilet flushing, and non-potable water use
    • blackwater recycling system
      • collects, treats, and recycles wastewater containing human waste, primarily from toilets.
      • involves preliminary steps and a key treatment stage in the bio-tank.
      • The treated water is then returned to the building for use in water closets and irrigation.
    • low-flow plumbing system
    • discharge or seepage to streams
    • direct or controlled discharge to sewers

Goal 3: Urban Green Spaces and Reduce Heat Island Effects

image
  • Measure:  percentage of plant coverage in the building
  • Targets:
    • minimally acceptable value: 20% of plant coverage
    • desired / target value: 40% of plant coverage
  • Strategies:
    • green roofs/gardens
      • effective stormwater management by reducing runoff and delaying flow rates
      • serve as natural insulation
      • enhance biodiversity in urban areas, providing habitats for plants and animals
      • contribute aesthetic value to buildings, elevating the overall urban landscape
