“…The extensive and comprehensive literature on this subject have pointed out that all the refurbishment interventions focused on building envelope rather than heating system renovation are very expensive and with a longer pay back time [7][8][9]13,15,17,19,29,31,40]. In particular, in [9] the authors have demonstrated that among the possible refurbishment solutions on a historical school building the lowest payback period is due to thermostatic valve installation (0.7 years), heat pump installation (2 years), and gas boiler replacement (4.5 years).…”

“…Recent studies on this subject have built up complete, integrated databases useful for the identification and checking of possible intervention strategies to reduce energy consumption in this sector [8,9] In particular, the authors have foregrounded the fact that a significant item regarding losses (i.e., energy, money, and costs) is due to inefficiencies in the management of building-plant systems that can be easily overcome by simple, low cost actions [8]. Educational buildings in Europe account for 20% of the entire non-residential floor space where good indoor comfort and air quality are essential for efficient educational development, but also increase of knowledge on how energy is used and consumed to enhance the awareness of school managers of the importance of improving energy efficiency and reducing energy costs [10][11][12][13][14][15].…”

“…Some authors have also highlighted that there is a considerable non-calculated potential for energy savings and improvement of indoor conditions in school buildings, promoting student and teacher productivity, and wellbeing [12,13]. In particular, in [21], the authors showed that, for high temperature cities (i.e., those located in hot regions such as Saudi Arabia and characterized by extreme changes in microclimatic conditions) school building architectural design could include natural ventilation techniques with the highest efficacy if cross-ventilation typology is realized for specific classrooms: the consequent benefits should lead to indoor air quality improvement, operation cost reduction, and satisfactory indoor thermal comfort.…”

Italy has a huge cultural heritage, most of which consists of historical buildings that have changed their original function and use over time. The complex question of building and plant system refurbishment and retrofitting mainly derives from this crucial aspect. The aim of this paper is to provide a simple provisional tool useful for the assessment of efficient, energy sustainable refurbishment solutions for historical buildings and their plant systems. The Dante Alighieri high school (with an important music department) in Florence was the case study. We proposed a method based on dynamic simulations that allows plant design guarantying indoor air quality (IAQ) and thermal comfort, as well as energy efficiency, but, at the same time offering reversibility and mobility as well as ease of management and maintenance. Transient simulations of building-plant system were specifically addressed dynamic control and adaptive proportional regulation, so as to ensure that the plant adapts to the change of building and indoor environment thermo-physics and thermo-hygrometric parameters. Results showed that important refurbishment and retrofitting operations for energy saving are possible and effective for historical buildings if they are oriented to sustainability-i.e., low environmental impact, indoor thermo-hygrometric conditions, ventilation, air quality, and user wellbeing improvement-in compliance with preventive protection constraints.

“…Recently, some studies have pointed out the high energy and environmental impact of school buildings (Gaitani et al 2010;Lassandro, Cosola, and Tundo 2015;Alshamrani, Galal, and Alkass 2014;Santamouris et al 2007;Wang et al 2015). In Italy, the current state of these buildings has been recognised as a national emergency (Antonini et al 2015).…”

Distributed, Renewable and Interactive energy Systems (DRIs) are revolutionizing the concept of infrastructure by introducing a set of new properties. The implications of the new system properties in the realm of Urban Design are often neglected. This paper proposes a procedure to reconcile DRIs and urban patterns. This procedure is tested on 23 school buildings in four urban regions of the Ostiense district in Rome. Findings suggest that the identification of existing buildings as active, neutral and passive nodes in DRIs can make a contribution to Urban Design decisions to exploit the renewable energy production capacity inherent in urban patterns.

“…Despite the plethora of research focused on school buildings and historic constructions, there are only a few papers that merge the three concepts this article is focused on, that is, POE, historic constructions and school buildings. Lassandro et al [31] introduced a new methodology combining POE, environmental monitoring, energy simulations and, as an innovative concept, a virtual tour to make audit results more friendly to the school community. IEQ analysis has also become a very important asset for POE investigations, as depicted by Hanna [32] who ran a wide study about daylighting, acoustics and thermal comfort using students' satisfaction responses at the Glasgow School of Art.…”

With attention increasingly shifting toward adaptation and energy upgrade of existing and historic buildings, research on Post-Occupancy Evaluation (POE) has grown notably in recent years. School buildings are a significant asset to the European building stock and an important field of investigation because of the peculiarities of the end users and the impact of indoor environmental conditions on their health and productivity. Building on recent literature, particularly the method of Povl Ole Fanger, this research presents the results of a quantitative and qualitative study performed to assess the thermal comfort conditions of a primary school located in a historic building in Villar del Arzobispo, Spain. As the study involves six and seven-year-old pupils, appropriate questionnaires for subjective thermal comfort evaluation were defined with the pedagogical support of the teachers, who also took part in the research and helped deliver the surveys to the children. The Predicted Mean Vote (PMV) and Percentage of Dissatisfied (PD) were then calculated for the evaluation of thermal comfort from measurements and questionnaires, for both pupils and teachers, using the classroom as a sample size. The results show a difference between pupils' and teachers' subjective opinions, with the children displaying a higher and more-difficult-to-reach threshold for indoor thermal comfort.
