Abstract

The paper presents an experimental study for an energy and structural upgrade of an existing school buildings in the north east of Italy. The first objective regards the identification of optimal measures of intervention for energy improvement toward nZEB requirements. The methodology is based on the guidelines of the IEA-EBC project Annex 56 "Cost-Effective Energy and Carbon Emissions Optimization in Building Renovation". According to the Italian legislation (D.M. 26/06/2015) the research defines a set of parameters for intervention on envelope and systems through the minimization of the energy demand and the associated carbon dioxide emissions with the least possible financial commitment. Each measure is analyzed in terms of by a dynamic simulation for energy performance and also by an estimation of the global costs (intervention costs, maintenance and exercise) related to a reference period of 30 years. The second objective concerns on a seismic adjustment using innovative techniques of intervention. The use of new high-performance materials such as FRP (Fiber Reinforced Polymer) and lightweight fiber-reinforced concrete allows consolidation of the most vulnerable structural elements by means of a minimally invasive intervention, thus ensuring the static improvement of the building while respecting its historical and architectural identity. The seismic retrofit project was developed by a survey carried out in situ, in order to obtain the main information on the state of the structure and its components, and to identify the main critical issues. The characterization of the soil and the building followed with the Italian Building Code. The structural system was defined in a Finite Element Model (FEM) to study the seismic behavior through a software for structural analysis and calculation. At last a proposal was developed to find the best global behavior of the building by intervening on the vulnerable structural elements.
