One especially important facility which “Lacasa” offers is the possibility to switch between two different simulation modes at any time:

1. Determination of loads: After the definition of the desired target conditions such as room temperature, humidity and CO2 content of the air, the system determines the required heating and cooling requirements as well as the amount of fresh air needed for a given architecture, climatic conditions, usage and construction.

2. Determination of the actual state: If the system was modelled, properly dimen­sioned and equipped with tools to regulate the desired target conditions, its capabili­ties can then immediately be determined by a simulation that corresponds to real — life operating conditions.

All calculated data is stored with a time stamp in a so-called MAT-file that can currently be displayed with 6 different graphical options. In addition, data are provided in tabulated text files.
