DuPont Pioneer needed a 21st century laboratory space that included cold rooms, culture rooms, and entomology rooms. This need was satisfied by building the Reid "E" Laboratory/Office Building which also included highly flexible office space to support the laboratories. Baker Group design engineers thought outside the box for design of the innovative environmental chambers. A central chiller plant was also installed to support existing and future laboratory buildings. Features of the facility's mechanical systems include:
Custom Environmental Chamber
- Entomology Area
- Rear Rooms (55 degrees F night, 85 degrees F day)
- Cage Rooms (80 - 85 degrees F @ 100% R.H.)
- Hatching Room (55 degrees F)
- Cold Rooms - 4 degree C room plus/minus 1 degree C anywhere
- Light Culture Rooms - 26 degrees C plus/minus 1 degree C anywhere
- Dark Culture Rooms - 26 degree C plus/minus 1 degree C anywhere
- Centralized low temperature process cooling plant
- Integrate temperature control with BAS system
- 30% savings compared to traditional environmental chamber designs
Piping Systems
- Natural gas, compressed air and vacuum gases piped to each laboratory and fume hoods
- Continuously available condenser water system
- Chilled water plant combining chillers from three separate buildings
- Low temperature chilled water
- D. I. and R. O. Systems
Heat Recovery
- Air to water system - provides a 30% reduction in heating energy
Air Handling System
- Single pass system
- Three stages of filtration
- Reclaim, heating and chilled water coils
- Steam humidification
Exhaust Air System
- Strobic exhaust fans
- S. S. duct construction
- Fume hood VAV control, continuous monitoring of face velocity
