This project received LEED NC Silver Certification for new construction and includes daylight modeling and solar simulation engineering. A daylight harvesting system is incorporated to reduce the energy and lighting loads required in the administrative areas. It is Geisinger’s first LEED certified project. The impact of daylighting on the interior environment of the building was considered of high importance, and main axis of the building placed so that the majority of fenestrations would be either on the South-facing facade or North-facing facade. In order to most effectively utilize glazing in the building envelope design and promote views of the surrounding landscaping and green roof, the South facade became almost all glazing, while the North facade was slit with thin floor to ceiling windows. Allowing daylight harvesting to play a major role in dictating the orientation of the building resulted in maximized energy efficiency and conservation. The open office areas utilize continuously dimmable ballasts that are interlocked with area photocells that vary the light levels in response to the available daylight. Upon completion of the building energy simulation, a savings of 41.2% was calculated in accordance with the LEED Version 2.1. This project won an International Illumination Design Award of Merit in 2008. It was also published in Lighting Design + Architecture (LD+A) in February of 2008. The article was titled "Daylight on Display."
