- Abstract
- In buildings with stratified room air temperature, improved accuracy in calculated annual energy consumption and air temperatures should be obtained by including a two zone or linear temperature stratification model in the simulation programs. This paper reviews the principles of a two zone model and a model with linear temperature stratification and shows how the latter can be implemented in existing simulation programs with one air node in each zone. The model is implemented in the Norwegian simulation program FRES (Flexible Room Climate and Energy Simulator). The model is applied on an existing atrium, and the results are compared to measurements. Two models are tested, constant air stratification and a model using a separate heat balance for the air volumne near the floor. The results are promising, and some further work should be carried out to evaluate the model for a wider range of conditions.
