Greenhouse and Classrooms Committee Summary July 11, 2008 

Project Number 208071

Summary of a programming meeting held at 8:00 am on Friday, July 11, 2008 at Joliet Junior College. These notes record our understanding of items discussed and decisions made at this meeting. Please notify us within seven (7) calendar days of any necessary additions or corrections.

The purpose of this meeting is to finalize the building program based upon the final gross square footages.

Attendance

• Jim Ethridge - JJC
• Richard T. Rivera - JJC
• Caryn Genens - JJC
• Lisa Perkins - JJC
• Margaret Semmer - JJC
• Abe Conde - JJC Student
• Jason Lembke - Legat Architects

Items Discussed

1. Programming – Greenhouse (12,000 gsf)
   1. The greenhouses will be 36' wide x 110' long.
   2. 3 greenhouses will be built. The final equipment and style of greenhouse will be determined after Jim's trip to Ohio.
   3. Greenhouse water: the plant irrigation will occur via either the echo system for hanging baskets or Ebb and Flood tables. The water will be fed by a two tank system. The first tank will collect gray water after irrigation then pass through a filter system into a second tank for reuse. It is desired to have this system under slab in the greenhouse.
   4. The greenhouses will have concrete slab floors with drains.
   5. The side walls will be 14' tall.
   6. House 1:
      1. Collection Side
      2. Propagation side
      3. Ventilation will need to be solved on the collection side, depending upon the style of greenhouse chosen (operable roof vs. through ventilation). More information will follow pending Jim's findings in Ohio.
   7. Houses 2 and 3:
      • Propagation
   8. The group discussed the polycarbonate for the glazing of the greenhouse. Jason explained about the LEED checklist and charrette process. He mentioned that a preliminary checklist was completed and that a balance will be needed between program spaces and mechanical systems to achieve LEED points. In that effort, it would be highly beneficial to have the materials for the greenhouse extracted and manufactured within a 500 mile radius of Joilet, Jason asked Jim to see what manufacturer's were utilizing towards LEED while he was in Ohio. Jim stated that it didn't matter to him where the components came from and it would be fine to obtain the polycarbonate locally. The group relayed past experience with the contractors assembling the existing greenhouses and difficulties encountered. Jason indicated he would specify that the constructor have documented experience with greenhouse installation.
   9. Jim explained that the 3 peak per house configuration was desirable from a maintenance standpoint. A single peak configuration would yield larger sheets of polycarbonate and make replacement difficult.
2. Building program
   1. Jason explained that the 5000 gsf would need to include a grossing factor for corridors, mechanical systems, toilets and lobby space. Initially, a 40% grossing factor will be used.
   2. The group listed the minimum required spaces and sizes: (see previous meeting minutes for additional programmatic information by space)
      1. Offices: 2 will be required at 140 sf (per teachers union agreement, sf to be verified)
      2. Horticulture Lab: 1344 sf
      3. Prep room: 215 sf
      4. Work Room/Shop: 800 sf (will need to be multipurpose, moveable tables, etc)
      5. Pesticide storage: 36 sf (will need dedicated ventilation)
      6. Shower: 50 sf
      7. Emergency Shower (included within room)
      8. Coolers: 9 1/2' x 15' in total: 143 sf.
      9. Head House:
         1. Potting tables: 60 sf, in tables, 3' wide, 20' long. Can be in L shape configuration, doesn't need to be in straight line.
         2. 4 Palettes of soil.
         3. Storage shelves: 300 gsf; can be stacked = net 4'x4' floor area. Storage is in Rubbermaid bins.
         4. Greenhouse mechanicals (sf in grossing factor)
3. Landscape Storage
   • Rich and Jim will work on finding space in the barn for landscape storage.
4. Lobby
   • A small amount of lobby space will be taken from the grossing factor.
5. Parking
   • Jason thought that approximately 40-45 spaces exist on the site. The group confirmed 60 spaces will be needed to account for students arriving for the next class while students are still attending the previous class.
