Thermal comfort with natural ventilation

This LEED Platinum building maximizes its thermal mass by using night cooling in the summer. In the winter, the control system monitors indoor and outdoor temperatures to ensure that the automatic windows will open to lower indoor CO2 levels without compromising thermal comfort. Sitting at USDA zone 5b with average low temperatures of -15˚ to -10˚F, thermal comfort is key in addition to access to fresh air. These design elements enhance occupant productivity and wellbeing without the aid of energy-consuming mechanical systems.
