Abstract

The improvement of school buildings is a primary aim which cannot be ignored in a vision of a more sustainable and safe society. Because of the widespread degradation state of Italian schools, it is undelayable to ensure safety conditions not only in terms of structural behaviour but also of users' comfort and hygienic conditions, improving at the same time the energy performance and efficiency of buildings (Directives: 2010/31/UE on nearly zero energy buildings and 2012/27/UE). The aim of this research work is to define an optimized and integrated survey method for the assessment of building energy performance and comfort deficit in order to identify the design solutions for the enhancement of the building potentialities. The proposed method is based on a holistic-systemic approach with an experimental validation that integrates the methods of instrumental investigation in situ with post-occupancy evaluation through the users' involvement and their subjective evaluation of comfort conditions (ASHRAE scale), during the actual use of the building. In order to reduce survey time and to optimize resources utilization, this method also proposes the identification of sample areas with different use conditions, orientation and position inside the building, for the assessment of the energy performance of the whole building. The school building choice was made as a function of the energy behaviour that is representative and comparable to that of buildings with certain widespread typological and constructive characteristics in Italy (reinforced concrete buildings of the 60s-70s). The assessment of the building energy performance and of lighting and thermal comfort, arising from the integration of objective data with the subjective users' perceptions, was the basis for defining a number of improvement works on both the building envelope (opaque and glazing surfaces) and systems, also through the use of renewable energy sources (RES) and better management strategies. The hypothesized interventions were of the step-by-step type, in order to identify benchmarks of minimal improvement in function of the scarce available resources optimization.
