              Design Considerations: Stairwell placement- Combine main circulation and main stairwell to
            conserve space.  Lighting, heating & cooling- Consider skylights or an inner atrium
            to reduce the need for artificial illumination.  Natural light also provides natural
            ventilation.  Operable windows allow outdoor air to penetrate indoors.  Wayfinding- Incorporate signage into the building plan. 
            Consolidate rooms and areas to save space.    Tools: Scaled drawings and architectural modeling
 Case Studies to research:  Stairwell placement -National Audubon Society Headquarters, New York, NY - 
            Connecting stairs are located at south-facing windows in order to allow daylight to reach
            central public areas.  Lighting, heating & cooling- The Body Shop, Raleigh, NC  -  An adaptive
            reuse project where new openings in the interior and exterior walls admit more light
            into the mezzanine and warehouse space. -Herman Miller SQA Facility, Zeeland, MI - A new building has a skylight-to-floor ratio
            or 5% of the total floor area.
