This is especially true in the southeastern U.S. where tempering the outside air is a necessity the majority of the year. Because they reflect natural light, use of lighter colors in common areas and in offices decreases the demand for artificial lighting. This is not a call to make office interiors look like sterile cleanroom environments. However, conscientious use of lighter colors in relation to the available natural light is an important factor to consider. Storm Water Treatment The easiest way to treat storm water in Florida is to use retention ponds, but this site is extremely compact and required an alternate solution. The project development team incorporated an underground exfiltration system to meet the requirements for storm water treatment. Florida’s St. Johns River Water Management District (SJRWMD) had already instituted regulations for storm water quality equal to that of the LEED requirements for reduction of total suspended solids (TSS) by 80%. The engineer only had to enlarge the system slightly to handle Summer 2009 the quantity of storm water to attain LEED credits, allowing the system to treat 7,812 ft3 of storm water at one time. This system also has the added benefit of more readily promoting infiltration of water into the Florida aquifer. Placement of the storm water system underground allows use of the aboveground area for parking to augment the parking shared between the campus buildings. Applying Project Lessons The Commercial Building was Stellar’s first experience to design, construct and obtain LEED certification for a project incorporating 60 HIGH PERFORMING BUILDINGS Se pt Btu/ft2 (thousands) 400 Btu (millions)
