Moisture management in buildings and industrial processes consumes an extensive amount of energy. The conventional approach of condensing the moisture through cooling to dew point temperature and subsequent heating to meet the desired dry bulb conditions makes the process highly inefficient and CO2 emissions intense. In order to meet our decarbonization goals a disruptive approach to moisture management in buildings is required. This session presents different dehumidification technologies based on novel materials and system architectures. The first two presentations focus on material characterization and innovation while the latter presentations demonstrate a novel highly efficient membrane based dehumidification technology.
