Thermal Activated Buildings Systems;the Resulting Thermal Comfort

摘要

A new approach to design adequate solutions for the indoor climate of buildings was developed during the last years.Radiant Heating Systems or also called Thermally Activated Building Systems,with thermo activated concrete is used in combination with natural supply ventilation and mechanical exhaust ventilation.In four of these new buildings,one office and three schools,the systems were examined and measurements were undertaken and questionnaires held to determine the thermal comfort generated by these new indoor climate concepts.The calculated PMV values indicate a slightly better thermal comfort than is perceived by the users according to the results of the questionnaires.TABS itself can assure an acceptable indoor temperature.Most of the users are satisfied during winter.Questionnaire shows that the building users are slightly less satisfied in summer.Overall the new TABS concepts lead only to a small improvement in the winter situation.
