Heat Loss Report

The Heat Loss Report is produced when a heating design day has been created. The report has 4 distinct sections:

1. Project Details

Figure 3.1.1: The Project Details section of the Heat Sizing Report.

The Project Details section of the report provides some details on the report, including the name of the TBD file and the date the report was generated.

2. Heat Loss Breakdown

Figure 3.1.2: The Heat Loss Breakdown section of the Heat Sizing Report.

The Heat Loss Breakdown section gives a breakdown, for each zone, of the heat losses within the zone. It starts off by stating some of the inputs entered into the wizard for the zone, along with the area and volume of the zone. Below that, a table lists the heat loss by conduction for each building element in the zone. Underneath the table, the total heat loss through the building elements is listed, along with the heat loss due to infiltration, ventilation and air movement. Finally the total heat loss for each zone is listed, taking into account of the size fraction applied to the zone.

3. Building Summary

Figure 3.1.3: The Building Summary section of the Heat Sizing Report.

The Building Summary section provides a breakdown of the heat losses for the building. At the top, it reports the total floor area and volume for all reported zones. Then, in the table, it reports the heat loss by conduction through each building element in the building. Underneath the table, the total heat loss through the building elements is listed, along with the heat loss due to infiltration, ventilation and air movement. Finally the total heat loss for the building is listed, taking into account of the size fraction applied to each zone.

4. Zone by Zone Breakdown Table

Figure 3.1.4: The Zone by Zone Breakdown Table on the Heat Sizing Report.

The Zone by Zone Breakdown Table just summaries the: fabric losses, infiltration losses, ventilation losses, air movement losses, size fraction, radiant proportion and total heat loss for each zone.
