The main entrance and the largest glassed area are located on the north side of Suwanee City Hall. This minimizes the need for artificial lighting. It also reduces glare and air-conditioning load while improving occupant comfort and perception of the space. Suwanee is a suburb of Atlanta. Lighting Design Lighting design is complex because of factors ranging from aesthetics to occupancy types to specific task requirements. Combining daylighting with artificial lighting increases complexity, but improves occupant satisfaction and lowers operating costs. Lighting design professionals, electrical contractors, commissioning authorities, and operation and maintenance staff need to work together to obtain maximum benefits from a lighting retrofit. If lighting modifications are part of a grander plan or a new building, a full team of design, construction and commissioning professionals may be needed. The team must be committed to project goals and have experience with high performance building design and construction. Using the commissioning process to develop the owner’s project requirements (OPR) organizes and clearly states the project’s design and performance requirements and helps ensure all team members have a solid understanding of project objectives and criteria. It is typically necessary to modify standard agreements to include the deliverables outlined in an OPR, and to define a method for modifying defined requirements during project development. Remedies should be included in the agreements to handle situations where the design and construction team cannot meet the defined requirements. The team should include an independent lighting designer and an independent commissioning authority (CxA).The lighting designer should not be tied to a specific manufacturer and must be able to provide guidance Photo courtesy city of Suwanee The Day-Brite|Omega|Capri Lighting Institute’s learning center in Tupelo, Miss., can demonstrate the various effects associated with different types of lamps and lamp temperatures, providing professionals and their clients a preview of the visual environment being created by the design team.
