## 1.2. Co-operation with other programs of InstalSystem package

Program Instal-heat&energy is an element of InstalSystem package, also including Instal-therm program assisting in designing of convection central heating and water radiant heating systems. Due to possibility of co-operation with Instal-therm program, quick transfer of heat losses calculation results to central heating system data is also possible. Data exchange is realized by means of data file, which is common for both applications.

Because the data files can be read by both applications and they include data and calculation results and the building structure is specified in the same way in both applications (partition into storeys, flats and compartments), the building data created in Instal-therm during edition or import of storey plan views are read in Instal-heat&energy. This enables, among other things, calculations of heat losses for buildings, the storey plan views of which have been received from an architect in form of DWG/DXF files.

Defining of partition construction (layers) in building is performed in Instal-heat&energy program with help of material database and partition patterns library. Optionally it is possible to use partitions with enforced „U”- or “R”- value, without specification of their layers. It is also possible to declare thermal properties of inhomogeneous partitions being present in the project.

The user is able to complete in Instal-heat&energy program additional data of partitions and compartments, the basic geometrical data of which, together with structure of entire building, have been read from the plan view. Values of temperature in compartments can be completed in any application. Heat losses in compartments calculated in Instal-heat&energy are saved to file with pointing out of so-called reduced heat losses (without losses through partitions being heating surfaces), which enables appropriate selection of both unit heaters and radiant heaters. Return to Instal-therm enables creating of diagram and calculation of central heating installation for calculated heat losses.

Every change of data in Instal-heat&energy causes counting over of heat losses and makes possible later system update in Instal-therm program.
