Abstract:

In the Swiss research project OptiControl (www.opticontrol.ethz.ch), new predictive building control strategies are developed and applied to a fully occupied, well instrumented demonstrator building. The demonstrator building is a typical Swiss office building located in Allschwil close to Basel. The building has 5 levels and a conditioned floor area of ca. 6’000 m2. Heating and cooling are mainly done with the aid of thermally activated building systems (TABS). Hygienic air change is ensured by an air handling unit including energy recovery.
This work presents our experience with the application of integrated predictive Rule-Based Control (RBC) to the demonstrator building. In a companion paper (Model Predictive Control of a Swiss Office Building), the results of the implementation of novel model predictive control on the demonstrator building are presented.
The newly developed control strategies integrate heating, cooling, ventilation and blind control. This integrated approach differs strongly from most conventional control solutions, where different control parts of the plants are but only loosely coordinated, if at all. Comparison of measurements and simulations for our demonstrator building showed that the newly developed control strategies are superior to the reference (original) control strategy in terms of control performance and operation. The benefit of using weather forecasts was found to be due to improved blind operation as well as due to anticipating future weather with slow heating and cooling systems. Moreover, it was found that the newly developed RBC strategies can in particular reduce tuning effort significantly.
