Sustainable Site

  • Urban redevelopment area in central business area
  • Preferred parking for carpooling to serve 13.33% of occupants
  • Adjacency to public transportation
  • 34.2% of non roof impervious areas are provided non colored concrete and shading to reduce heat island effect.
  • 100% of roof meets Energy Star emissivity requirements to reduce heat islands effect. 

Water Efficiency

  • 53% reduction of potable water usage for landscaping through high efficiency irrigation systems and low demand indigenous and adaptive plantings
  • 23.31% water use reduction  through use of low-flow and water efficient fixtures and appliances

Energy & Atmosphere

  • Optimized energy efficiency through a 20.6% energy reduction compared to ASHRAE 90.1-1999.
  • Improved roof insulation, radiant base board heating, variable speed condensers
  • Combines under floor air distribution with indirect/direct evaporative cooling to reduce annual energy consumption
  • Improved lighting power density.
  • Plan for sub metering water and energy usage
  • HCFC and Halon free HVAC (heating ventilation and air conditioning) equipment 
  • Green power purchased from Wind Current to meet 100% of the building electrical needs for minimum of 2 years

Materials & Resources

  • Occupant recycling
  • Reuse of historic building achieved 100% of the shell and 50% of the non shell
  • Diverted 75.77% of construction waste through effective waste management plan
  • 5.04% of total building materials by value contain recycled materials
    Indoor Environmental Quality (IEQ)
  • CO2 sensors monitor to outside ambient levels and increased ventilation if exceeding thresholds
  • Under floor air delivery system provides increased ventilation effectiveness in compliance with ASHRAE 129-1997
  • Construction IAQ Management plan was in compliance with SMACNA guidelines. During construction, MERV 8  filters were installed at grilles and MERV 13 filters prior to occupancy
  • Low emitting carpet was used
  • Indoor pollutant source control
  • Controllability of non perimeter temperature, ventilation and lighting systems
  • Designed for thermal comfort compliance with ASHRAE 55 – 1992 for relative humidity and temperature
  • Thermal comfort monitoring system installed for compliance with ASHRAE 55 – 1992 for relative humidity and temperature
  • 2% day lighting  factor for 81% of occupied space for critical visual tasks achieve through introduction of 2 full height atria
  • 90.6% of all occupants have direct line of sight to views for all space occupied for critical visual tasks
