Summary report tab

Contains controls used to view a summary report of the ASHRAE Heat Loss calculation results.

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 ASHRAE Heat Loss calculation. Selecting Design basis in the selector panel (left) updates the reports display panel (right), scrolling to the Design basis display. 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 fabric losses using room and location information. Heat loss model — Displays the name of the heat loss model used for the calculation. 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 the losses attributed to the room constructions and infiltration on the design day. Room ref. — Displays the name of each room included in the calculation. Inside temp. — Displays the inside design day temperature. Fabric loss — Displays the total losses through the room surfaces, including walls, ceilings, roofs, floors, doors and windows for each room. 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 infiltration loss for each selected room. Infiltration losses result from the movement of outside air into the room through wall cracks, wall joints, electrical outlets, and through the materials in the building constructions. Total loss — Displays the total loss for each room. Total loss is 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 the losses attributed to the room constructions and infiltration on the design day.

Room ref. — Displays the name of each room included in the calculation.
Inside temp. — Displays the inside design day temperature.
Fabric loss — Displays the total losses through the room surfaces, including walls, ceilings, roofs, floors, doors and windows for each room. Heat flow through each exposed wall is computed from the wall area, U value, cooling and load temperature differences.
