Active Heat Exchanger
The Active Heat Exchanger (AHE) research programme started as an engineering development project, and discovered first an engineering research question and then a health research question. The AHE is a retrofit ventilation device which solves the problem of there being no large-scale, long-term environmental epidemiology data for indoor air quality, despite most humans spending most of their lives indoors. The device addresses the ventilation component of sick housing while generating the continuous surveillance data the field needs. ...
