Analisi della qualità degli ambienti interni

The aim of this work is to analyze the indoor environmental quality in buildings. There are several objectives: to study the parameters that define the indoor environmental quality, to study the methods of investigation in relation to the targets of the analysis and to analyze the influence of the occupants in the management of indoor parameters. In the first part of this work parameters that characterize the indoor environment are described; these are thermal comfort, air quality, lighting and acoustic. For each of them it will be analyzed the regulations and guidelines in force. The regulation UNI EN 15251 is described, because it is the primary reference for the definition of the indoor environmental quality. In addition, the standard is currently under review, bringing changes that are integrated with the topics discussed in this paper. In the second chapter the certification of building both energy and indoor is described. Three voluntary certification are presented, with a focus on the CasaClima certification, that has been used in a research on the analysis of air quality in hotels and, by the means of assessment questionnaires, in a global analysis for the re-certification of buildings. In the third part of this work measurement techniques are described, such as instrumentation monitoring and subjective measures carried out with questionnaires. Instruments described have been used in the analysis of the three case studies presented in chapter 4. In order to analyze thermal comfort, acoustic, lighting, management and heal of occupants and their mutual connections in residential buildings an apartment located in Padova has been analyzed. In it indoor air quality and ventilation problems were reported. The other two case study are non-residential buildings. Topics of indoor air quality, ventilation, energy efficiency and layout of school building and an office building have been analyzed. The school building, the School Stroppari located in Tezze sul Brenta, presents an innovative ventilation system with an ...
