Setting	Description
Design basis	Used to display key design parameters considered for the ASHRAE RTS 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 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. External shading is/is not considered — Indicates external shading is or is not considered. The use of external shading for gains calculations is set in the Default Manager dialog box’s Simulation run-time control panel. If you opt to include external shading, the calculation will check if each window is shaded by external obstructions at each hour of the day. Shaded windows will receive diffuse solar radiation only. Fins are/are not considered — Indicates fins are or are not considered. The use of external shading for gains calculations is set in the Default Manager dialog box’s Simulation run-time control panel. Outside drybulb temperature — Displays the maximum outside drybulb temperature experienced on the design day. This value comes from the weather profile being used for the project. No Additional fresh air — Indicates no additional fresh air changes due to forced fresh air ventilation or opening windows will be conisdered in the calculation Rooms included — Displays the number of rooms included in the calculation.
Results for room: [Room name]	For each included room, the peak heat gain and peak hour will be displayed for the room. The project total loads for all the included rooms are produced by adding room loads on an hour-by-hour basis for each of the 24 hours of the design day. The coincident peak hour for all rooms is that hour which has the maximum coincident load. If fresh air loads are specified with the design data, these will be included in the project total loads. Sun Time — Displays the hour of the peak design day from 1 through 24. Outside temp. — Displays the outside temperature for each hour of the design day. The outside temperature is derived from the weather data associated with the project location. Envelope — Heat flow through each exposed wall is computed for each hour of the design day 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. Glazing — For each window, and for each hour of the design day, the maximum solar gain on the sunlit portion is determined, and the actual sunlit and shaded areas of glass are computed from the window dimensions and the side and top projection distances. Cooling load factors for each hour of the day are applied, depending on whether interior shading is specified or not. The shading coefficient is incorporated for all window types. For the glass in the shade, the wall cooling load factor for north facing, shaded walls is used. The thermal weight used is that specified for the room. Orientations are rationalized from angles to the nearest ASHRAE orientation (N, NNE, NE, etcetera). Rooflights are treated in exactly the same way as windows, except that they are assumed to be unshaded and subjected to radiation for a horizontal surface. Infiltration — The infiltration heat gain for each hour of the design day is found from the room volume, the infiltration air change rate, and the inside and outside temperatures. Infiltration gains are separated into their sensible and latent components. Internal — Gains from internal sources for each hour of the design day are determined. Internal gains are separated into their sensible and latent components. Outside air — For each hour of the design day, outside air may be introduced locally to rooms, in which case it will affect the room load. Outside air from the central plant will form part of the supply air and will be a load on the central plant as well. Conditioned primary air will be supplied at the defined supply temperature, with optional supply humidity control. Conditioned primary air will affect both room loads and central plant loads. If conditioned primary outside air is specified and this outside air requires heating at the central plant, when the building requires cooling (or vice versa), then the outside air heat load will be excluded from the central plant loads. Outside air gains are separated into their sensible and latent components. Total load — Displays the sum of all the loads in the room for each hour of the design day.
