216 DESIGN DEVELOPMENT

7 How will daylighting and natural ventilation be impacted by the choice of work-
space partitions and their location? Are the interior designers fully incorporated
into the project team?
8 How do we plan to control sunlight entering the building? Can we get daylight
into the building without glare that would inhibit productivity?
9 Will we use fixed exterior shading devices, either horizontal or vertical?
10 Can we consider dynamic façade systems respond to changing solar orientation
and exterior lighting levels?
11 Have we studied the use of light shelves for daylighting? How will they impact
the building’s aesthetics?
12 Have we considered the use of skylights and light wells to get light into the build-
ing? How will we deal with potential glare from such systems? Can they be ade-
quately controlled in more southerly climates?
13 If the building is naturally ventilated, have we demonstrated with a CFD model
that air distribution will provide laminar flow in at least 90 percent of all occupied
spaces, for at least 95 percent of the hours of occupancy, so that everyone can
share in the benefits?
14 Have we considered the use of operable windows in the building and located such
windows? Is there at least one operable window for each 200 square feet of
perimeter space (within 20 feet of the window)?
15 Are we going to provide for individual light, air, and temperature controls for at
least 50 percent building occupants (e.g., through underfloor air distribution
systems)?
16 If we use underfloor air systems, have we considered how these systems will be
installed so they don’t leak (air) and who will maintain the area under the finished
floor to keep it clean?
17 Does our design ensure that ground-level or rooftop air intakes will not be
impacted by sources of pollution, including HVAC exhaust, chemical uses, truck
loading, smoking areas, and possible off-site pollutants?
18 Have we specified a permanent carbon dioxide monitoring system that
informs operational adjustments of the ventilation system, so that we can
have demand-controlled ventilation, especially in spaces with widely varying
occupancy? Are we meeting ASHRAE 62.1-2004 standards for outside air
delivery?

PLATINUM PROJECT PROFILE

Sweetwater Creek State Park Visitor Center, Lithia Springs, Georgia
Designed by the Gerding Collaborative, the 8700-square-feet Sweetwater Creek
State Park Visitor Center provides exhibit space, offices, retail area, learning lab-
oratory, classrooms, and restrooms. The project was completed in 2006 and cost
$175 per square foot. Thirty-eight percent (nearly 4000 square feet) of the build-
ing’s roof area is used for rainwater collection, to supply an estimated 44 percent
