Light and heavy energy refurbishments of Mediterranean offices. Part I: energy audit of an institutional building on the Naples coast

摘要

The public hand has a demonstrative role in matter of energy efficiency of owned or occupied buildings. Here, the energy audit of a high-rise university building is proposed. The methodology adopts the Cost-Optimal approach, as imposed by the European guidelines (EU Directive 2010/31/EU), based on feasibility studies performed with transient energy simulations. In particular, in situ surveys (infrared thermography and measurements of U-values) have been used for building, as detailed as possible, the building model for the numerical study. The analysis evidenced high-energy demands, mainly for the space heating and cooling. A second study discusses a cost-effective energy retrofit.
