Envelope:
Roofing Used –

  • Garden roof assembly on single ply roofing assembly on concrete roof on steel framing
  • skylight system with fritted glass and metal roof
  • glass fiber roofing system
  • single play roofing over rigid board insulation over concrete over metal deck
  • built-up roof over rigid insulation over metal decking

Curtain wall – Aluminum window system with insulated glass

Precast Concrete Walls backed by acoustic batting insulation and gypsum wall board

Mechanical Systems:

The offices and classrooms are served by a VAV system which is controlled by three air handling units.  AHU-1 serves the west wing of the building with 17,000 CFM of air, while AHU-2 and 3 serves the east wing with 15,500 CFM each.  The forum is served by a radiant floor system and two 6000 CFM gravity ventilators for relief.  The bathrooms located on the first and second floor are served by two 1000 CFM fan coil units.  Chilled water is supplied by a 10 gallon expansion tank.  Heating is supplied by a 1200 MBH boiler.

Electrical Systems:

Power is spread throughout the building by an 800A, 480/277V distribution panel which feeds two panel boards that control lighting, mechanical equipment, and various first floor spaces.  It also feeds two step down transformers that each feed a 600A, 208/120V distribution panel.  One panel serves 7 panel boards which control first floor outlets and miscellaneous power.  The other panel serves 5 panel boards which control the second floor.

Lighting Systems:

Classrooms are illuminated by 20’ fluorescent direct/indirect lighting fixtures. Offices and hallways have 2’x2’ and 2’x4’ ceiling mounted fluorescent lighting.  The lecture room has various types of direct fluorescent downlighting.  The rotunda has several types of recessed and surface mounted HID lighting.  The forum has 8” 2-lamp fluorescent downlighting underneath the second floor’s walkways, and 22” pendant mounted HID lighting.

Structural Systems:

The floor of the building is 5” concrete slab on grade (3500psi).  The second floor is concrete (3500psi) on metal deck supported by W-flange steel beams, and steel columns. The steel columns are only located in the east wing of the building and are supported by concrete spread footings.
