HVAC

Self-sufficient - not self-sufficient
Renewable Fuels - solar power too expensive
Fossil Fuels - gas-fired absorption heater and chiller provided at a single source
Ventilation -outside air circulates within offices at 26 CFM per person
Cooling System -air is conditioned w/ a high-efficiency , gas burning chiller
HVAC Intake & Exhaust - intake located on roof, away from street level, loading docks, etc.
Personal Environment Modules - private offices have individually controlled heat, ventilation &   A/C

 

Glazing

Lightshelves - not used

 

Daylighting Monitors - full range dimming linked to the amount of daylight

 

Occupancy Sensors - motion sensors

 

Superwindows - Heat Mirror™ technology used- low emissivity, wavelength selective coated film with a shade coefficient equal to .41
South Facing Glass - natural daylight incorporated at south-facing windows in order to allow daylight to reach central areas
Skylights & Clerestories - clerestory windows & skylight
Courtyards & Atria - not used

Insulation / Energy Efficiency

High Insulation - Air Krete™  blown into cavity walls.  Wall insulation = R-11, -ceiling insulation= R-30, -roof insulation= R-33
Low Emission - low emissive materials used
Recyclable & Natural Materials - existing building reinforced
Earth Covered Building   X
Asbestos - removed from existing building

 

Building Lifecycle/ Longevity

Adaptive Reuse - renovated old structure
Monitoring Systems or Devices - duct systems allow for easy maintenance

Materials

Natural Materials - carpet padding -100% hair and jute on homosote
Recyclable & Renewable - floor tiles are recycled glass, countertops are recycled plastic, recycled newsprint used in underlaying for carpeting 
Local Materials - used when possible
Non-toxic/ Low-toxicity -manufacturing history of every specified material, system and product analyzed
Harmony w/Environment - Use of materials that are harmonious with environment 

Roofing

Storm Water Drainage   X
Roof Top Units   X
Solar Units   X
Indoor Ecology Design Considerations N/A

Space Planning

Smaller spaces w/large group areas - open office plan with 
Shared spaces - shared work spaces available
Telecommuters - not discussed

Indoor Air Quality

Air Changes per hour -  indoor air changes 6.2 times/hour

 

Smoking Policy - no smoking policy

 

Air Filtration - 80% particulates filtered from air
Natural Ventilation - windows used for natural ventilation
Building Materials - materials give off few or no chemicals, undyed wool carpets, carpet padding 100% recycled paper & 80% particulates are filtered from the air
"Breathing Skin"   X
Pesticide Use -not permitted
Indoor Flora - individual preference

Lighting

Natural Daylighting - south facing glass, large amount of windows, interior walls incorporate partially glazed walls to further permit daylight into interior areas
Artificial Lighting - high-efficiency fluorescents, pendant light fixtures, compact-fluorescent task lights, 
Circuiting & Switching - office lights-controlled by heat sensors
Material / Product Content Design Considerations N/A

Furniture

Natural & Recycled - recycled Herman Miller components system utilized
Raw Materials   X
Acquisition - Manufacturing history of every specified material and product analyzed by architect
Processing & Mfr. "    "
Product Distribution - product should require a minimum of inherent energy in its transportation
No / Low Emissions - minimization of toxic content is primary objective
Renewability - recycled and reusable

Walls & Partitions
