These include at the top of the table collective results for the entire project, such as:

No. of sources | number of sources in project |
Total no. of terminal units | number of all terminal units in project |
Total no. of pipe-runs | number of all pipe-runs in project |
Total no. of manifolds | total number of manifolds in the system under design |

Total spec. heat loss in room Q/F | total specified heat loss in rooms | [W]
Total spec. output of TU Qreq/Freq | total output of terminal units specified in project | [W]

Results assigned to individual heat sources in the project are displayed below. Source data are described in the first line:

- Source <source_name>

- Application <Heating / Cooling>

- Medium < medium_ name> – type of medium specified in the data table and, if medium other than water, concentration.

Next part of the table contains the following information:
