Residential Night Ventilation Cooling Field Monitoring Project
Project Number PGE 0710 Organization PG&E End-use HVAC Sector Residential Project Year(s) 2007 - 2008Project Summary
This project analyzes and tests the integration of night ventilation cooling technology into a standard heating, ventilation, and air conditioning (HVAC) system. Night ventilation systems automatically ventilate houses using the normal air handler, supply, and return duct system, as well as a smart thermostat, mechanical damper, inlet and exhaust ducts. The smart thermostat monitors indoor and outdoor temperatures. When the outdoor temperature is lower than indoor, the system turns the air conditioning system off and ventilates the house with 100% outside air. Ventilation occurs throughout the night, exhausting the building mass and preparing the house for the next day. For more information, please contact the sponsoring organization.
