Simulation programs are widely used in the design of heating and cooling devices. However, modeling of
the whole building with simulation programs is exceptional at least in Finland. We have built and utilized
whole building models in a commissioning project to estimate the energy consumption and the indoor
climate in an educational building. We have also used component models in the commissioning of a
ventilation system.
One of our pilots was modeled very accurately using IDA-ICE. Finnish engineering office Granlund
LTD has modeled the same building with a simulation program called RIUSKA, which is based on
DOE-2. We present an analysis based on verification results of simulation to measured energy
consumption, and the results of component models to the actual properties of HVAC system
