From: Dataset on occupant behavior, indoor environment, and energy use before and after dormitory retrofit
This figure compares indoor thermal conditions and HVAC energy use during extreme winter events, both before and after the retrofit. The site experienced an extreme cold spell before the retrofit in the last week of January 2022, when temperatures dropped to about −20 °C. A similar event occurred after the retrofit in the first week of February 2023, with temperatures dropping to around −21 °C. The figure shows a significant reduction in HVAC energy consumption during the extreme cold event after the retrofit.
