Heat loss
Under the Heat Loss menu, you will find the results of the Heat Loss module. The Heat Loss module contains two types of results: tables and reports.
Statistics
In the statistics, you will find an overall summary and, per room, the various components for Heat Loss. The generic functions of the tables can be found on the Tables webpage. This also allows the results to be displayed in 3D.
Statistics on building (complex) level

| ΦT,iae [W] | Heat loss due to transmission to adjacent unheated spaces |
| Φextr [W] | Heat losses that do not always (simultaneously) occur |
| ΦT,ig [W] | Heat loss due to transmission to the ground |
| Φadd [W] | System losses |
| Φi [W] | Heat loss due to infiltration |
| ΦHL, verd. [W] | Power generator/flow through distributor |
| Φgain [W] | Heat gain |
| ΦHL,v per op [W/m²] | Power generator/flow through distributor per surface area |
| ΦHL,v per vol [W/m³] | Power generator/flow through distributor per volume |

| Φvent [W] | Heat loss due to ventilation |
| Φhu [W] | Surcharge for operational limitation |
| Φgain, v* [W] | Heat gain through ventilation |

Flexible Word Report (docx)
The Word report for Heat Loss can be arranged flexibly. Adjust the layout in MS Word (DOCX) settings before recalculating Heat Loss at Calculation Status. These settings allow:
- Flexible chapter order
- Toggle chapters on/off
- Toggle rooms and zones on/off
- Automatically generated floor plans
- Unlimited images via project settings
- Improved Word export with navigation pane and table of contents
In the Word report, you find all results and assumptions. Navigate using the left menu. The top toolbar offers various view options.
Toolbar functionality:
- Print/export to Word
- Jumping to a page shows its top
- Scroll updates page number
- Search updates live, continues with F3 or magnifier
Images in the report
New in the Heat Loss report is the ability to add an unlimited number of images. You can add images to the report by uploading them in Project Data. You can also save a 3D image in the geometry section, which can be found under Photos and Drawings. Floor plans are automatically included in the report.
An image’s placement in the report depends on its type (Cover Page/Floor Plan/Image/Impression).
Cover Page
- Warmteverlies
The first image under project data with the type Cover Page is used for the cover page of the report.
Image
All images with the type ‘Image’ are included in the report.
Floor plan
- Warmteverlies
In the heat loss report, floor plans are added automatically. You do not need to generate these with the floor plan button. This button is still available for other reports as long as the report has not been updated there.
All images generated with the Save Floor Plans button are automatically given the type Floor Plan. These are not included in the heat loss report because the floor plans are generated automatically during the calculation. If you still want to add the floor plans to the report, you need to change the type to Image.
Floor plans generated during the flow visualization Ventilation Flows WV are included in the report.
Impression
- Warmteverlies
Impressions are not included in the heat loss report. If you want them to be included, change the type to Image.
Text (TXT)
The Text (TXT) report contains the same sections as the Word report. This report can be printed and exported as a PDF.
