The Global Environment Centre Foundation (GEC) is an entity that supports the UNEP’s International Environmental Technology Centre (IETC), based in Japan.
This strategy uses the outside air to cool an internal environment, without allowing external and internal airstreams to directly mix. Cool outside air is drawn through a heat recovery unit then immediately exhausted, while internal air is drawn from the room and circulated through the heat recovery unit before being re-introduced to the room. The outside air?s cool thermal energy is thus transferred to the internal air via the heat recovery unit without the two streams directly mixing.
