The Northern Arizona University (NAU) Applied Research & Development (ARD) Facility is arguably the most sustainable laboratory building in the world. This signature 61,000 SF facility brings together groups for research, study and application of sustainable technologies. NAU assembled a world-class sustainability team for this project, identifying the goal of LEED Platinum certification from the start. The project was delivered as Construction Manager At Risk (CMAR), enabling the contractor to provide valuable cost estimates during the design phase. Cost input and experience was essential in preserving the goal of Platinum certification. The Commissioning Agent & Energy Modeler were also involved in the design, which was extremely valuable when exploring new technologies such as underfloor air distribution, a vegetated green roof and a radiant floor heating system.
