The project team quickly committed itself to attaining LEED certification including LEED criteria although not specified in the project buy out and including provisions for obtaining the proper LEED documentation for miscellaneous items; challenging, but doable, as the team worked with the trades. The initial orientation of trade contractors to scope items and letter template requirements played a key role in obtaining the information.

Among the sustainable criteria achieved are:
Waste Management

	The project team focused on waste management on the site and strived for the more stringent credit of 75% or greater diversion of waste from landfills. By end of 2006, 85% of construction waste was diverted from the landfill and, in January 2008, as the project statistics were submitted for certification, the overall waste diverted was 88%.
	Over 2.1 million pounds (1,068 tons) of waste was disposed of which 1.8 million pounds (914 tons) were recycled.
	Daily tracking of trucks during demolition.
	Separate containers for general trash, metals and cardboard were utilized.
	Refrigerant, glass, ballasts, lamps, soil, etc. were tracked as removed from site.

Lighting

The project team utilized compact fluorescent lighting (CFLs) as temporary lighting during phase two contributing to energy savings including cost savings, CO2 emissions, safety and overall project quality. After just three months, compact fluorescent lights prevented over 63,000 pounds of CO2 emissions while providing an energy cost savings of over $4,800 (based on national US Department of Energy, Energy Information Administration reports and averages).

Other LEED elements

	Close proximity to public transportation and bicycle storage provided.
	30% reduction in water use (targeted).
	100% of building shell was re-used (specified materials call for over 10% recycled content.
	System controllability, ventilation, low-emitting materials and thermal comfort are among the indoor factors.

Bovis Lend Lease LMB Princeton managed the two-phase, 95,000 square foot renovation of two research buildings including the demolition of laboratory, laboratory support and office areas, and the rebuilding of new, state-of-the-art laboratories utilizing a flexible laboratory furniture/casework concept.

Phase I consisted of 20,000 square feet of laboratory space renovation, which then provided the swing space, permitting the renovation of 75,000 square feet of laboratory space. The project scope also involves building equipment and utilities upgrade including air handling units, exhaust fans, heating skids, etc.
