Information

Test Case 950 of the ASHRAE 140-2007: Calculation of heating/cooling loads for room version heavy excited by internal and external gains.

Boundary conditions

  • yearly profile for outdoor air temperature and solar radiation in hourly steps
  • no heating and daily profile for set temperatures of cooling
  • constant internal gains and daily profile for infiltration rate
