Verification and validation of a simulation model for energy use in buildings

Different modeling approaches address the problem of energy efficiency in the building sector, being a multi-parametric problem. Physical or white-box approaches describe physical phenomena with sets of equations, and offer high interpretability in physical terms. Present work deals with a calculation-based monthly quasi-steady state simulation model for energy use in buildings based on ISO 13790 standard methodologies and presents its implementation. Model verification and validation is performed according to procedures of EN 15265 standard and against a real hospital usecase.
