We have begun data collection to compare baseline energy consumption to energy consumption after installation of the pilot project - energy efficient HVAC control retrofit. Sensors needed were determined and installed. Data collection has begun with 4 weeks of data so far. Initial review of the data has identified several challenges with the HVAC already including heating valves that are leaking by providing heat where not required, which explains why the Air Handler is getting rid of heat even in the winter. The variable air volume system is also not varying as it should. This is demonstrating some pitfalls of pneumatically controlled HVAC systems.
