ABSTRACT: The paper will discuss the design of a bi-directional thermo-hygroscopic façade as a dedicated outdoor air system to cool and dehumidify outside air. The system is a variant of dedicated outdoor air systems to separate dehumidification and cooling in air-conditioning equipment and locates components within the building envelope. The integrated hybrid-building envelope relies on... Read more »
