Ecopilot software is an add-on to an existing Building Automation System (BAS) that uses real-time data, indoor wireless temperature sensors, 5-day weather forecasts to exploit the building thermal mass to provide heating and maintain cooling within higher mass concrete building structures. The technology consists of hardware and software containing real time AI (artificial intelligence) algorithm that sends temperature setpoint offsets to central HVAC systems and creates dynamic scheduling of start and stop times of central HVAC equipment, such as boilers, chillers or AHU’s (air handling units).
