Experimental evaluation of thermal comfort on underground trains

As part of a programme of research investigating thermal comfort on underground trains in London, BRE designed and constructed an experimental facility to be as realistic as possible for "passenger " subjects. Tests were carried out to investigate passengers' thermal comfort in realistic summer conditions. 574 subjects completed questionnaires , the data were included in the analysis, a model was derived to predict passenger response. As expected , temperature was the most important parameter influencing passenger comfort.
