In the paper authors have undertaken a trial to present energetic effect developed by cooperation of a surface heating system and a building construction on the basis of object modeling using ESP-r software. Performed analyses concern impact of heat capacity of the building construction and different heating panels on final energetic effectiveness taking into consideration the algorithm of heating system operation control. The article is an example of a changing approach to building facilities designing ‒ in case of integrated method of design it allows for obtaining considerable improvement of energetic quality.
