Figure 6.34 Daily measured and calculated heating energy balance of the Town Hall in Scharnhauser
Park at a constant air change rate of 0.4 h − 1 . The calculated values for Sunday are highlighted

The dependence of heating energy on daily irradiance is small, which is shown for the
months of January and February in Figure 6.37.
To achieve a better agreement between measurement and simulation, a simple
dynamic model was then used (Keller, 1997). The building can have several zones at
different temperature setpoints and effective heat capacities C . As a consequence,
heat fluxes 12 between two different zones, the zone and the environment e and into
