S&C will design a shut the sash pilot program to be implemented at a building with a VAV CFH system. The Beckman Institute has been identified as an acceptable building to launch the pilot program and the administration at this building is in full support. The pilot program will use various methods to maximize compliance. S&C staff will work with building personnel and occupants to refine methods, training, and components needed to develop a model program. Metrics to track success are discussed below. Once the pilot program is complete, data will be evaluated and recommendations will be made for implementing the model program in other buildings. The pilot program will last 3 months (12 weeks). In the weeks prior to initiation of the pilot program S&C will develop a pilot program plan, develop informational media, and collect baseline metrics. Once all of the baseline data has been collected, informational literature about the pilot program will be posted and distributed to affected principal investigators (PIs) and in-person informational briefings will be held. The evening before the pilot program is to begin S&C will post “shut the sash” placards on each of the CFHs and leave informational literature in a conspicuous location within the laboratory. S&C will make weekly CFH inspections throughout the pilot program period to collect data (data collected will depend on metrics) and reinforce benefits of shutting the sash. Metrics that will be used to monitor the effectiveness of the program are detailed below.
