Temporary gas radiating heaters were installed in Alkmaar's 'St.Laurenskerk' (St. Lawrence's Church) in the winter of 1998/99, in addition to the existing floor heating, to be used during events. Because the application of gas radiation heaters is being considered as a permanent solution for the thermal comfort problem in the church, the city of Alkmaar commissioned ECN to investigate the effects of the functioning of the heaters. The main concerns are comfort, energy use, and possible negative effects of this type of heating on the building (and the organ). A detailed image of the interior climate of the church was obtained by use of infrared photographs, hourly measurements of air temperature and humidity, comfort measurements and infiltration measurements
