Field evaluation of thermal and acoustical comfort in eight North-American buildings using embedded radiant systems

We performed a post-occupancy assessment based on 500 occupant surveys in eight buildings using embedded radiant heating and cooling systems. This study follows-up on a quantitative assessment of 60 office buildings that found radiant and all-air buildings have comparable temperature and acoustic sa...
