Abstract
In this paper the subjective evaluation of the indoor environment of a secondary school in Treviso (Italy) is presented. Field campaigns have been carried out during the winter season in order to assess people overall satisfaction about the environment, their behavior towards discomfort and their interactions with the building and the systems. A specific questionnaire has been elaborated, paying particular attention to the occupants target and to the questions needed to grasp not only the comfort feedbacks, but also the dynamics and the individual students’ attitudes that can influence the building energy performance. A first general evaluation has been elaborated for all the comfort areas (i.e. thermal, visual, acoustic and air quality) applying the method proposed by the EN 15251 for thermal comfort to all the comfort aspects. Then, further analyses have been implemented focusing on thermal conditions, in order to integrate the results and to check if an average comfort evaluation can be significant and representative of all the spaces in the building. Results show that specific classrooms conditions seem not to match completely the overall general analysis, even if representative differentiated spaces were selected for the analysis.
