Goal 1: Zero Net Energy

  • Measure: building energy consumption & generation (kBtu)
  • Targets:
    • minimally acceptable value: net zero site energy
    • desired / target value: net zero source energy
  • Strategies:
    • rooftop solar
    • heat pumps
    • passive solar
    • efficient appliances (Energy STAR), lighting fixtures, etc.
    • daylighting
    • daylight and motion sensors

Goal 2: Low Embodied Carbon

  • Measure: kg CO2 eq
    • LCA
    • EC3
  • Targets:
    • minimally acceptable value: 10% below baseline design
    • desired / target value: 30% below baseline design
  • Strategies:
    • mass timber as a structural component
    • rapidly renewable or recycled materials when possible
    • local materials
    • reduced slab thickness (if site permits)
    • alternative insulation materials

Goal 3: Occupant Comfort

  • Measure:
    • biophilic design & views
    • thermal comfort (CBE thermal comfort tool)
    • ventilation (cfm/person)
  • Targets:
    • minimally acceptable value:
      • views from >50% of the building
      • complies with ASHRAE standard 55
      • 15 cfm/person
    • desired / target value
      • views from >70% of the building
      • 30 cfm/person
  • Strategies:
    • mass timber also adds a biophilic element
    • incorporation of greenery both inside and outside with windows overlooking
    • thermal mass
    • natural ventilation
    • low emitting materials
    • daylighting
    • operable windows
