Summary report tab

Contains controls used to view a summary report of the results of the CIBSE heat loss calculation conducted using the Simple Model steady state heat loss model.

Tip: You can open the Results Viewer utility to step through the calculations for displayed results by selecting the result value and clicking for more information (as prompted).

Setting	Description
Design basis	Used to display key design parameters considered for the CIBSE heat loss calculation conducted using the Simple Model steady state heat loss model. Selecting Design basis in the selector panel (left) updates the reports display panel (right). Scroll to the Design basis display to view these design data properties: Location — Displays the project location set for the project in the Properties dialog box’s Properties For: Site panel. Design Day — Displays the day on which the greatest loads are experienced. The design day is used to compute sun positions and solar gains and to calculate the hourly outside dry and wet bulb temperatures using the weather database information for the specified location. Heat loss model — Displays the steady state calculation model to used for calculating the heat losses. CIBSE Heat Loss (Simple) – Set by default, the specified design air or resultant temperatures are used. Rooms Included — Displays the number of rooms included in the calculation
Summary results	Summary results give a single line summary for each room showing the inside temperature and fabric and infiltration losses. Room ref. — Displays the name of each project room. Inside temp. — Displays the mean inside temperature for each room. Fabric loss — Displays the total losses through the room surfaces, including walls, ceilings, roofs, floors, doors and windows. Heat flow through each exposed wall is computed from the wall area, U value, cooling and load temperature differences. The temperature difference value is automatically included in the calculation, and a correction is made for wall color, inside temperature and average outside temperature. The wall color correction is carried out using the wall absorption coefficient to solar radiation. Infiltration loss — Displays the total losses through infiltration. The infiltration losses are found from the room volume, the infiltration air change rate, and the inside and outside temperatures. Total loss — Displays the sum of the fabric and infiltration losses.

Summary results

Summary results give a single line summary for each room showing the inside temperature and fabric and infiltration losses.

Room ref. — Displays the name of each project room.
Inside temp. — Displays the mean inside temperature for each room.
