Title: Energy Efficient Building Ventilation Systems: Innovative Building-Integrated Enthalpy Recovery

Program Document ·
OSTI ID:1046652

BEETIT Project: A2 is developing a building moisture and heat exchange technology that leverages a new material and design to create healthy buildings with lower energy use. Commercial building owners/operators are demanding buildings with greater energy efficiency and healthier indoor environments. A2 is developing a membrane-based heat and moisture exchanger that controls humidity by transferring the water vapor in the incoming fresh air to the drier air leaving the building. Unlike conventional systems, A2 locates the heat and moisture exchanger within the depths of the building’s wall to slow down the air flow and increase the surface area that captures humidity, but with less fan power. The system’s integration into the wall reduces the size and demand on the air conditioning equipment and increases liable floor area flexibility.
