## 1.2. Communication with other applications of the InstalSystem package

Instal-therm is a component of the InstalSystem package, which also include Instal-heat&energy for calculating heat losses and seasonal heat demand in buildings. Data exchange is made with the use of a data file, which is assigned to both Instal-therm and Instal-heat&energy. Heat losses of rooms calculated by the latter application are saved to the file with a distinction made of the so-called reduced heat losses (losses exclusive of heat loss across partitions that constitute the heating surfaces), enabling proper sizing of both convectors and radiant surface heating units. If radiators are sized by Instal-heat&energy, this information is also transferred to Instal-therm. The structure of the building (storeys, apartments and rooms) is recognised and presented by both applications in the same manner. When using base drawings made with CAD software and loaded onto Instal-therm by means of DWG or DXF files, it is possible to calculate heat losses in the building with Instal-heat&energy and then to make diagram and system calculations with Instal-therm.

The package is supplied with an application for scanning building plans and for combining and rescaling these scanned plans. Files created with this application are in the form of bitmaps and they may be used to make a drawing background for drawing the plan of the heating system and also for drawing floor plan with the use of objects predefined in Instal-therm (walls, rooms, etc.).

Another component of the package is Instal-mat, which gathers information on materials from one or more projects created with Instal-therm and Instal-san and on that basis draws up a collective bill of materials and materials order. At this stage the bill is appended with prices.
