Calculation of building heating demand in EPIQR

Energy and exergy analyses of space heating in buildings

“…The temperature factor is consequently 0 for construction elements facing the outdoor air [15]. The ventilation heat loss _ Q V (W) can be calculated by using the following equation:…”

“…g j is the total energy transmittance of the glazing and can be estimated to be 0.75 for double glazing. F sh is the possible shading effects of other surrounding buildings and the F no correction for non-orthogonal radiation on the windowpanes and both of them can be estimated to be 0.9 for most cases [15,27].…”

“…They found that the results of energy labeling are very similar for both simulation programs. Wittchen and Aggerholm [15] studied calculation of building heating demand in EPIQR based on energy analysis. Prager et al [16] investigated the effect of painted facades with spectrally selective properties on the energy balance of a building and compared real measured data from an outdoor test of facade samples with data calculated using the ESP-r simulation program.…”

“…The values are taken from [14]. : The utilization factor of heat gains; based on a graph from [18]. : The solar radiation per area of windows.…”

“…: The reduction factor due to shadowing effects, based on [18]. : The reduction factor due to the entire glass area being less than the total window area, based on [18].…”
