Abstract

The article studies seven heating seasons’ data of heat consumption of heating in 24-storey residential apartment building in St. Petersburg with ventilated façade, office and commercial spaces on the ground floor. It is established that heat consumption for heating depends on the year passed in operation of building since completion. During the first three years increased heat consumption is observed due to drying of walls of the building, which must be taken into account in a design of the building’s heating and maintenance systems. It is concluded that in a period of no less than three years since completion, operated building should be tested to confirm values of required specific energy heat consumption for heating in the heating season.
