Here is a preliminary scope of "green" methods of power, heating and cooling systems and water retention in the building. I am not sure on the specifics of how everything is correctly sized or if its all valid.
Photovoltaic Cells:
Type: Grid Connect the pv system (w/invertor)- allows system to feed off of the main grid if solar power is unavaible
Location - Roof of spine/billboard (hides the panels from view)
Approximate Area: 1900 s.f. of avaible space for panel array
Orientation: All panels to be oriented South - this minimizes the loss of solar power within the pv system. Also all panels to be tilted to maximize the solar angle (although I am not sure if it is better to base the tilt on summer or winter angles).
Net Metering: Sell back any excess power collected during the day and buy back excess during evening hours.
Manufacturer: http://www.gepower.com/prod_serv/products/solar/en/index.htm
Geo-Thermal System:
Premise: Use the Earth's consistent core temp. to heat and cool the building as needed - convert the temp into a hydronic method of cooling (i.e. chilled beams??).
Method: Open loop system utilizes the ground water below the site (based on info from site lecture) to circulate water from the Earth to the building via a pump within a mechanical room. The benefit of this is that standard heating and cooling processes use electric and/or gas to heat and cool spaces, which has a high loss of energy when transferring heating/cooling. The geo-thermal system is in effect the most efficinet since it in effect uses no additional energy other then the pump to heat and cool spaces.
Water Retention:
Use cistrines to store rain water that has been collected by the roofs and use this as a filtered grey water system - eliminating a complete dependence on public water services. The system will be contained in a system/container below grade, where treatment and distribution will take place.
Regarding site water: water will be retained per the requirement of 1"/hr through various landscaping features.
One note of concern is erosion control and how to control this: http://www.nedia.com/

Joe, please make sure you get feedback from Chris.
Joe, are you still using brise-soleis to control the light in the class rooms? Could these devices be PV panel arrays?
I talked with Chris back in Boston about the whole geo-thermal open loop system, he didnt really see any problems with that system, but there are a few things I would like to discuss with him via blogging or office hours. As far as the brise-soleis and the pv panels, I really would prefer hiding those elements, because I really dislike the look of them, I prefer the much cleaner/sleaker look of a anodized aluminum finish. To me, the whole PV system being exposed for aesthetic value really is not that pleasing to me.
