Vanderweil has piloted post-occupancy review to determine how buildings are used and discovered that gaps in installation, operation, and maintenance, which can result in excess energy and resource use, may be avoidable. Post-occupancy evaluation requires a small investment but yields results that can help alleviate owner issues with controls, circulation, and operational strategy. This session will share ways that project design, process, requirements, and communication can influence responsible use of building resources, and describe how the RGV360 program has helped evaluate and inform the design approach for upcoming projects.
