Information

Test Case 8 of the VDI 6007 Part 1: Calculation of indoor air temperature excited by a radiative and convective heat source for room version S with two exterior walls. It is based on Test Case 5.

Boundary conditions

  • daily profile for outdoor air temperature in hourly steps
  • daily profile for solar radiation on the exterior wall
  • daily profile for solar radiation through the windows in hourly steps
  • sunblind closes at >100 W/m2
  • no long-wave radiation exchange between exterior wall, windows and ambient environment

This test validates reaction of indoor air temperature at mixed internal gains and outdoor impacts including solar radiation on exterior walls.
