The method of calculating the cooling rate of a room when the heating system is turned off there is an important practical task. As a result of such calculation, the time within which the room will cool down to an acceptable temperature, is indicated. During this time, emergency brigades must restore heating in the building. The aim of the work is to provide some refinement of the existing fundamental calculation formula by taking into account additional factors affecting the cooling process of the room. These include: taking into account the time of the initial irregular cooling process, taking into account the heat storage capacity of internal enclosing structures and furniture or equipment in the room, consideration of the initial temperature conditions in external and internal enclosing structures when calculating their heat capacity. The proposed approximate engineering technique is verified by comparing the calculation results with the results of direct calculation by the numerical method of the non-stationary thermal regime of the room in the full statement.
