AUTOMATION OF THE CALCULATION OF HEAT LOSS THROUGH HORIZONTAL EXTERNAL ENCLOSING STRUCTURES WITH THE BREAKDOWN OF THE FLOOR OF THE ROOM INTO ZONES

Introduction: The calculation of heat loss of the room is a mandatory part of any project. Most of the information required for calculations is present in the building information model and can be extracted from it automatically. An example that requires the transformation of digital model information is the task of constructing room zones when calculating heat loss through the floor. Existing software products do not have modules that allow you to automatically calculate the heat loss of a room, including through the floor, breaking it down into zones. The object displacement functions built into the software products are not intended for constructing floor zones and cannot be used as a component of the developed module. These reasons determine the need to develop an algorithm for constructing zones that are necessary for calculating heat loss through the floor, and its implementation. 
Materials and methods: An algorithm for the formation of floor zones of a room is presented. The algorithm allows you to build zones for placing an arbitrary layout. 
Results: A plug-in for Autodesk Revit, which implements the proposed algorithm, was tested on the calculation of heat losses in the rooms of the technical floor of the building. As a result of the experiment, a reduction in the time required for the preparation of the initial information and for the calculation, from 4 hours to 2 minutes, was revealed. 
Conclusions: The developed software module, designed to calculate the heat loss of premises through the floor of premises, broken down into zones, is a step in the development of software products that use a digital building model as initial information.
