# 3. Project and its data

## 3.1. General information concerning structure of project data

Basic structure, on which the program Instal-heat&energy operates is a project, saved in one file on a disc. Project files have an extension ”.isb” and spare copies of previous versions -„~IB”. A file can contain only data used by the program for thermal calculations of a building or as well data of system. It is then used also by Instal-therm program. A file can be created in Instal-therm program and it can contain graphically created plan views of storeys and then it can be used in Instal-heat&energy for further work.

Project data in most extended case consist of:

- descriptive information about a project,

- general data of system,

- general data of a building,

- tabular information concerning definition (layers) of applied partitions,

- data concerning graphically entered elements of building,

- data concerning tabular entered elements of building,

- data concerning graphically entered elements of system,

- data concerning tabular entered elements of system (heaters),

- calculations options,

- results of thermal calculations of a building,

- results of system calculations,

- messages concerning last performed diagnostic or calculations, for each program,

- settings of elements configuration (appearance on drawings),

- information about used catalogues.

If it is intended to use both applications in one project: Instal-heat&energy and Instal-therm, it is recommended to work on one file, common for both applications. It will guarantee permanent update of data and results entered by the other application.

A significant advantage is the possibility of performing of thermal calculations of a building on graphical data, formed from storeys plan views, which have been created in Instal-therm or have been imported from DWG/DXF files. These data can act simultaneously as a base for system plan views.
