DESIGN CONSIDERATIONS

External Consideration

Design Outcome

N/A

Site Planning

   
Site Selection - 176 acre site of farmland & woods overlook the city of Ithaca  
Campus vs. High-Rise - Co housing arrangement (20-30 homes along a pedestrian street)  
Solar Access & Orientation -South facing windows absorb solar heat  
Prevailing Winds -Future provisions for wind-generated resistance electric heating  
Adjacent Buildings -Cohousing 
-Share heating units: every 8 homes are linked together w/ a single generator that taps natural heat existing underground
 
Disturbance of site throughout construction  - attempts made to reduce site disturbance  
Construction Waste Management  -waste is recycled when available  
Access/Egress & Circulation  - acess to the site is setback off the roadway approx. 400 yards  
Outdoor Lighting & Safety     X

Environmental Impact

   
Restoration & Preservation of Flora & Fauna -preserving & restoring over 80% of land as green space  
Groundwater control/ erosion control  - watershed area to control erosion  
Ecosystems (air, water, soil)  -all attempts made to keep ecosystesm in balance, -future greywater recycling system  

Transportation

   
Biking /Walking   -walking only on-site  
Mass Transit     X
Shuttle /Bus     X
Commuter Rideshare  -not organized  
Parking -Shared parking lot separated from homes  

Noise & Vibration

   
Effect of surrounding noise & vibration on new buildings     X
Amount of noise released into environment  -residential setting  

Core & Envelope

Design Considerations

N/A

Circulation

   
Stairwell Placement  

Lighting, Heating & Cooling  -unit sizes are kept to a minimum  
Wayfinding  -path system throughout site  
Building Form /Shape -Size of homes range from 922sf for one bedroom to 1300sf for three bedrooms  
Energy Efficiency - every 8 homes share heating units  
Harmony w/Environment  - natural materials used on sitein order to harmonize with natural surroundings  

HVAC

   
Self-sufficient     X
Renewable Fuels -every 8 homes are linked to a single generator that taps natural hear existing underground, -future renewable energy inputs  
Fossil Fuels - natural gas  
Ventilation - natural ventilation  
Cooling System - natural ventilation  
HVAC Intake & Exhaust     X
Personal Environment Modules  

Glazing

   
Lightshelves  

Daylighting Monitors  

Occupancy Sensors  

Superwindows -high-efficiency triple-paned  
South Facing Glass - south facing windows in all facilities  
Skylights & Clerestories -skylights used in homes  
Courtyards & Atria - homes exposed to courtyard and exterior site  

Insulation / Energy Efficiency

   
High Insulation -super-insulated with 6" of cellulose plastic housewrap, double wall which allows plumbing and wiring to run completely inside the insulating barrier  
Low Emission     X
Recyclable & Natural Materials     X
Earth Covered Building     X
Asbestos  

Building Lifecycle/ Longevity

   
Adaptive Reuse - future residential housing  
Monitoring Systems or Devices - regular community meetings  

Materials

   
Natural Materials - natural materials used throughout construction of site  
Recyclable & Renewable -used recycled materials where appropriate  
Local Materials - Used local materials  
Non-toxic/ Low-toxicity     X
Harmony w/Environment - Use of materials that are harmonious with environment   

Roofing

   
Storm Water Drainage - sited to permit storm water drainage  
Roof Top Units     X
Solar Units -solar panels  
Indoor Ecology Design Considerations N/A

Space Planning

   
Smaller spaces w/large group areas - small homes with green space next to each  
Shared spaces -Common House equipped with kitchen and dining rooms, offices, laundry facilities and meeting spaces for all residents  
Telecommuters - access permits telecommuting  

Indoor Air Quality

   
Air Changes per hour  

Smoking Policy  

Air Filtration  

Natural Ventilation - operable windows  
Building Materials - natural materials- wood  
"Breathing Skin" - plastic housewrap does not permit  
Pesticide Use -not permitted  
Indoor Flora - individual preference  

Lighting

   
Natural Daylighting - maximum solar gain through south facing window walls  
Artificial Lighting - compact fluorescent lighting  
Circuiting & Switching     X
