Experiences of Using Models and Information of Building Automation System in Commissioning

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
