This model adds another element for the roof. Roofs commonly
exhibit the same excitations as exterior walls but have different coefficients
of heat transfer due to their orientation. Adding an extra element for the roof
might lead to a finer resolution of the dynamic behaviour but increases
calculation times. The roof is parameterized via the length of the RC-chain
nRoof,
the vector of capacities CRoof[nRoof], the vector of resistances
RRoof[nRoof] and remaining resistances RRoofRem.
The image below shows the RC-network of this model.
