4. General method
The general principle of the RT 2012 calculation is that of a conventional Dynamic Thermal Simulation (DTS) – i.e. with conventional input data – carried out at hourly time steps.
Bbio, Tic and Cep are calculated using the same method, applied with more or less conventional parameters and taking into account more or less elements, depending on the value sought.
The Bbio and Cep coefficients are calculated over a full year, while the Tic coefficient is calculated over a specific period of time.
4.1 General calculation principle, the nodal method
The calculation is carried out at group level, corresponding to a room or group of rooms whose air is assumed to be homogeneous in terms of temperature and humidity....
