Heating, Cooling & Ventilation

• low volume, low energy displacement air distribution system
• fresh air is delivered directly to occupants through floor slab
  
• radiant heating and cooling delivered through ceiling slab
  
• air to air heat recovery and a geo-exchange ground loop, additional heat received from high efficiency district energy plant
  
• user operated awning windows at perimeter study spaces
  
• twin atria and a common roof monitor with automatic ventilating windows allow spent warm air to escape in warm weather
  
• large array of solar panels provides heat for district energy plant domestic hot water

Building Envelope

Exterior wall type 1:  Curtainwall

Allows maximum daylight penetration, protects from summer heat gain, permits low angle winter solar penetration & reduces electric lighting loads

• 25mm clear argon filled low e insulated glazing units with warm edge spacers
• glazing sizes maximized to increase thermal efficiency of wall
• vertically oriented mullion caps used as solar shading devices at west wall
• ceramic frit used on glass where required to minimize heat gain and light contrast
• laminated opaque glass solar shades

Exterior wall types 2 & 3:

• Brick masonry or corrugated zinc siding on insulated cavity (RSI 3.0 -R 17.2) on block masonry structure
• Spray insulation at wall penetrations and joints

Roof:

• 2 ply SBS roof with white capsheet  on (RSI 5.2 – R 30) rigid insulation
