    Abstract

    This paper deals with a simple model which predicts the vertical temperature gradient in a heated room. The gradient is calculated from a dimensionless temperature profile which is determined by two room air temperatures only, the mean temperature in the occupied zone and the mean temperature in the zone above the occupied zone. A model to calculate the two air temperatures has been developed and implemented in Suncode- PC, a thermal analysis programme for residential and small commercial buildings.
    The dimensionless temperature profile based on measurements in a laboratory test room is presented, and the improvement of the programme is validated by comparing laboratory measurements with simulated results
