“…On one side, the target has been to build a tool able to simulate the human body reactions to environmental conditions, so as to obtain a complete thermal environment meter. In this direction the papers by Bedford e Warner [3], Botsford, [4] and later Kuehn et al [5], who proposed devices sensitive to air humidity as well; Madsen [6], who proposed a tool that could simulate the human body answer to sensible heat exchanges, based on a human thermo-regulation model grounded on the Fanger theories; and eventually Mendes e Da Silva [7], who more recently proposed a device that could simulate the human body reactions to both sensible and latent heat exchanges.…”
