Light and heavy energy refurbishments of Mediterranean offices. Part II: cost-optimal energy renovation of an institutional building

摘要

A previous study has evidenced the poor energy performances of a building owned by the University of Naples Federico II. In detail, a reliable energy audit, by means of calibrated input, has been performed, and it revealed energy requests, polluting emissions and energy costs very high. By taking into consideration the exemplary role of the public hand, according to the EU Directives 2010/31/EE and 2012/27/EU, here a cost-optimal energy refurbishment is proposed, by analysing several energy efficiency measures, firstly singularly analysed and then combined in order to evaluate the super-positon effect.
