# 3. Project and its data

## 3.1. General information on the structure of project data

The basic structure on which operates is the project saved to one file on disk. Project files have an ”.ISB” extension, and spare copies of previous versions have an “~IB” extension.

The file may include only the data used by Instal-heat&energy to do heat calculations for a building, only data of the system (Instal-therm) or it may include both.

The file may also be created with Instal-therm and include graphically generated plan views of storeys and then it can be used in Instal-heat&energy or in both applications simultaneously.

Project data, in the most extended case, consist of:

- descriptive information about the project,

- general data of the system,

- general data of the building,

- tabular information on the structure (layers) of applied partitions,

- data on building components entered graphically,

- data on building components entered in tables,

- data on system components entered graphically,

- calculation options,

- results of heat calculations of the building,

- results of system calculations,

- messages of the most recent diagnostics or calculations, from each program,

- component configuration settings (appearance in drawings),

- information on the catalogues used.

If you intend to work on one project with both applications: Instal-heat&energy and Instal-therm, then it is advisable to use one file common to both applications. This ensures constant updating of data and results introduced by the other application. Otherwise heat loss calculation results must be copied from one application to the other or entered manually.

The possibility of making heat calculations of the building using graphical data obtained on the basis of plan views of storeys created with Instal-therm or imported from DWG/DXF files is a prominent feature of the package. These data may form the base for system plans.

The project file can cover one or more systems (installations) of any size and is divided into sheets, which usually consist of plan views of individual storeys (“Plan view” type sheet), one or more schematic views of the system (“Schematic view”) and optionally of drawings, which are not subject to calculations (“Sheet not calculated”). The editor is used for arranging and marking radiators, heating zones and manifolds on plans and the entire system (or only the part not shown on plan views) on the schematic view. In particular it is possible to represent the entire system on a schematic view only (e.g. radiator heating systems or cooling medium circulation systems) or on a plan view only (in the case of a small radiator or floor heating system).

If there is more than one source in one project, systems supplied from these separate sources must not be interconnected in any way. The type of system (heating / cooling) is defined by the source selected in the data table. If a system is supplied from a boiler, then the heating type is assigned automatically.
