Comparison of simplified and advanced building simulation tool with measured data

In the future building design must progress to a format where CO2 neutral societies are optimized as a whole and innovative technologies integrated. The purpose of this paper is to demonstrate the problems using a simplified design tool to simulate a complicated building and how this may not give sufficiently good results in terms of actual performance of the real building. This is illustrated by example of Viborg Town Hall using a simplified Danish tool Be10 and a dynamic Building Simulation Programme IES-VE. The model is evaluated based on actual weather data. In addition, IES-VE is evaluated using a Monte Carlo simulation in order to evaluate the confidence level of the models’ accuracy for Viborg Town Hall.
