DESIGN CONSIDERATIONS
 

External Consideration Design Outcome N/A

Site Planning

   
Site Selection -integration of the building with the site was a primary objective for the architects  
Campus vs. High-Rise - "street" design of building to connect offices and manufacturing  
Solar Access & Orientation -maximize solar access  
Prevailing Winds - design site with reforestation to buffer winds & encourage windblown snow to fall at areas other than at the building  
Adjacent Buildings -reforestation to visually screen adjacent homes  
Disturbance of site throughout construction -evaluation of soil disturbance during planning & construction as well as construction techniques utilized  
Construction Waste Management -recycled construction waste  
Access/Egress & Circulation     X
Outdoor Lighting & Safety     X

Environmental Impact

   
Restoration & Preservation of Flora & Fauna -replanting of native trees, grasses and wildflowers, -maintain 50% of site as natural habitat  
Groundwater control/ erosion control -site design that includes careful stormwater management, retention ponds, & nearby wetlands   
Ecosystems (air, water, soil) -site design creates a restorative biological process, and results in better water quality  

Transportation

   
Biking /Walking      X
Mass Transit     X
Shuttle /Bus     X
Commuter Rideshare     X
Parking - parking available  

Noise & Vibration

   
Effect of surrounding noise & vibration on new buildings -site location away from surrounding noise  
Amount of noise released into environment -reforestation provides acoustical privacy  

Core & Envelope

Design Considerations N/A
Circulation    
Stairwell Placement  

Lighting, Heating & Cooling -optimization of daylighting provide passive solar heat, remainder is electrical  
Wayfinding - public "street" design used to connect offices with manufacturing   
Building Form /Shape -integration with the landscape, building is a curved daylit "street"  
Energy Efficiency - 30% of heat generated through passive solar  
Harmony w/Environment -integration with surrounding landscape  
HVAC    
Self-sufficient     X
Renewable Fuels -30% of heat provided by passive solar heat  
Fossil Fuels - remainder of heat is electrical  
Ventilation - fresh air chases run on both sides of street to provide fresh filtered air  
Cooling System -centrifugal chiller that uses HFC 134a refrigerant  
HVAC Intake & Exhaust     X
Personal Environment Modules  

Glazing    
Lightshelves  

Daylighting Monitors -electronically controlled exterior blinds block undesirable glare

 

Occupancy Sensors -motion sensors installed where continuous lighting need only be provided when spaces are occupied

 

Superwindows -low-E argon filled glazing   
South Facing Glass - orientation to maximize solar gain  
Skylights & Clerestories - 8' x 8' skylight placed in each structural bay, -clerestories oriented for best possible lighting conditions  
Courtyards & Atria - atria within "street"  
Insulation / Energy Efficiency    
High Insulation - R-60 value for roof, R-20 for walls  
Low Emission -low emissive insulation utilized  
Recyclable & Natural Materials     X
Earth Covered Building     X
Asbestos  

Building Lifecycle/ Longevity    
Adaptive Reuse     X
Monitoring Systems or Devices     X 
Materials    
Natural Materials - building made of steel- lowest embodied energy   
Recyclable & Renewable     X
Local Materials -steel procured from a local source  
Non-toxic/ Low-toxicity -MSDS sheets reviewed for all materials  
Harmony w/Environment - integration with site, but industrial materials   
Roofing    
Storm Water Drainage -site design that includes careful stormwater management, retention ponds, & nearby wetlands  
Roof Top Units     X
Solar Units - passive solar heat collected  
Indoor Ecology Design Considerations N/A
Space Planning    
Smaller spaces w/large group areas     X
Shared spaces     X
Telecommuters     X
Indoor Air Quality    
Air Changes per hour -fresh air introduced 50,000CFM after being filtered

 

Smoking Policy - no smoking policy

 

Air Filtration -filters located at each intake remove any particles larger than 10microns in size

 

Natural Ventilation -fresh air introduced through filters  
Building Materials -steel frame, low/non-toxic materials utilized  
"Breathing Skin" -operable windows  
Pesticide Use -not permitted  
Indoor Flora - "street" includes extensive indoor flora  
Lighting    
Natural Daylighting - sun is primary source of daylighting, operable windows  
Artificial Lighting - controlled with electronic sensors that dim the electric lighting during times of sufficient daylight  
Circuiting & Switching -electronic sensors monitor lighting levels
