Active Strategies

HVAC Technologies

  1. Mixed mode ventilation.
  2. Radiant cooling floor and ceiling panels for simulation lab and basement floor.
  3. VRF for dedicated outdoor air system at 3.51 COP with CO2 control.
  4. Air cooled chiller with 3.35 COP (ARI).
  5. Passive cooling in non-summer months with underground tank and evaporative fluid cooler.
  6. Premium efficiency pump motors with VFDs.

Lighting Design 

  1. Daylight autonomy 75% time for over 90% of spaces.
  2. Daylighting and vacancy sensor control of lights at 4.7 W/m2.
  3. Office equipment control with occupancy sensor control.
