Fall 2008 Dartmouth Architecture 2/3 group project designing a new school on Governor's Island, NY.

10. Measures to Minimize Energy Usage
Our Focuses:
Solar -20 kW Photovoltaic system provide energy for the site
Wind-300 kW wind turbines provide energy on site
We can mimic the Queens Botanical Garden
and explore other measures to conserve energy:
1-Ground-source heat pumps as a source for heating
and cooling
2-Large windows and 16’ ceilings increase daylighting
3-Operable windows allow for cooling near
summertime
4-Modulating photoelectric daylight sensors
5-Occupancy sensors

16. Budget Analysis
Phase 1: Assuming we get solar panels and two wind turbines donated and installed at least a
year before the harbor school moves into the site, we could generate up to $806,200 in profit
from energy sales to the grid. This would cover the cost of extending the pier to accommodate
the turbines.
Phase 2: To construct the first floor of the waterfront building, which houses all the necessary
student activities, we assume a square foot cost of $430. The building footprint is 6800 sq. ft.
which gives an estimated cost of $2.9 million. The actual cost may in fact be lower since the
new SPAT center will make use of the existing foundation and structure. This figure is above
the target budget of 2 million but revenue from the turbines and solar panels should bring it
within range.
Phase 3: The green roof will cost an estimated $78000, which combined with the cost of a
pool, aquariums, and additional remodeling on the second floor, will total around $1 million.
We hope, however, to get sponsorships for several of these features including the green roof
and pool.
Phase 4: We don’t have an estimate for the cost of the habitat restoration but it would include
demolition of the bulkhead, transport of raw materials, and labor. This phase would coincide
chronologically and programmatically with the West 8/Rogers-Marvel landscaping scheme for
Governors Island so it a financial collaboration is conceivable.
