Cost-optimal analysis of Italian office buildings through the application of a quasi-steady state model validated by detailed dynamic simulation

In the paper a methodology for identifying the cost-optimal levels of minimum energy performance requirements (according to Directive 2010/31/EU), already introduced in a previous work, is applied to Italian reference office buildings, different in the glazed area. The optimal energy efficiency measures, resulting from the application of a quasi-steady state numerical model, are then modelled by means of a dynamic simulation tool and the deviations are discussed. The aim is to validate the simplified model and to pave the way for future researches on cost optimality by applying energy performance simulation.
