Indoor comfort is a critical determinant of the holistic educational experience, significantly influencing the well-being, concentration, and performance of students within the confines of school environments. Despite the widespread implementation of heating, ventilation, and air conditioning (HVAC) systems in educational institutions, achieving satisfactory thermal conditions, acceptable acoustics, and optimal daylight levels for occupants continues to pose a considerable challenge. In this review, we specifically delves into the parameters characterizing Italian school environments, recognizing their direct impact on students’learning and concentration. The primary objectives of this review are conducting a thorough examination of the current acustic conditions in Italian schools. The initial phase of our search strategy involved retrieving data from key databases, namely, Scopus, Web of Science, ScienceDirect, PubMed, and Google Scholar. Following the elimination of duplicate articles (n = 289), a total of 135 distinct papers remained for analysis. A critical review of the existing literature is presented based on these criteria, offering guidelines and recommendations for forthcoming studies. The critical review underscores various shortcomings in the current design, deployment, and documentation of multi-domain studies, signaling the need for enhanced quality in future research efforts.

“…However, because the western region straddles two major terrain steps in China, the terrain is undulating, the geological structure is complex, there are many fault zones, and the geological forces are very active [ 8 ]. The precipitation in the western region is concentrated, and the human agricultural production activities are strong, causing large-scale geological disasters [ 9 ]. Therefore, with the vigorous development of China's market economy, the economic losses caused by geological disasters will be even greater, seriously threatening the life and property safety of the Chinese people, and the development of China's economic and social construction will also be affected and constrained [ 10 ].…”

With the progress of the industrial revolution and the development of modern science and technology, China’s urbanization process has been promoted. Urban and rural economic and social construction has greatly improved the local appearance and social structure. Human activities and natural ecology have affected the whole geological-ecological process, further aggravated the geological-ecological damage, and caused more serious geological disasters, especially in some places (especially in mountainous areas). In recent years, strong geological disasters have occurred in Wenchuan, Yushu, and Lushan regions of China, which not only seriously endanger the life safety and social life of the affected people, but also damage the geological-ecological structure and social functions of the region, especially in the geographically sensitive Alpine urban areas. It also produced many secondary disasters, such as landslides and land collapses. Mountainous cities and towns have special requirements for construction land, which is difficult to construct. Industrial land resources are in short supply, urban and rural comprehensive construction land is not active, and cultivated land area resources are tight. Compared with plain towns with superior geological conditions, mountain towns are more vulnerable to adverse geological environment such as geological ecology, landform, ecological vegetation, and hydrology. The geographical natural environment, as an organic whole that combines and interacts with the geomorphic natural environment, the biological-ecological environment, and the human social management environment, is the main reason that affects the development of mountain towns. Once the mountain geological ecology is destroyed, a series of geological disasters will often be induced, which will seriously restrict the healthy development of mountain towns. Scientific management of the geological environment plays an important role in the assessment of the geological environment restoration of mountain towns after disasters. Therefore, taking the most beautiful counties in China, Baoxing City, and Tianquan County as examples, on the basis of studying the complex geological-ecological theory of geological disasters, this paper further improves the traditional ecological footprint model in China, and using the interval direct fuzzy information constructs the metric index of ecological restoration scheme of mountain towns, and determines the evaluation index and optimal scheme of ecological restoration. From the aspects of landscape layout construction, disaster prevention and mitigation planning and improvement, and environmental restoration project, the future geoecological restoration and response strategy of Lushan County are pointed out, which provide guidance for the postdisaster geoecological safety layout construction.

“…In the Northern European region, where the heating season lasts for 5-6 months, heat recovery systems are of particular importance [38,[56][57][58][59]. Mechanical ventilation systems with heat recovery stand as a pivotal component in the operation of energy-efficient buildings, as they can lead to significant energy savings [38,60,61]. A study by Evola et al (2017) emphasized that the adoption of CMV systems with heat recovery in residential units is a cost-effective and energy-efficient solution, offering significant energy savings and favorable payback periods, especially in cold climates, while addressing concerns related to indoor air quality and mold formation [62].…”

As building energy consumption gains ever-increasing attention worldwide, the focus on addressing it through the examination and optimization of efficient heat recovery solutions continues to intensify. With well-insulated and airtight buildings, the proportion of heating needs attributed to ventilation is growing, leading to the widespread integration and optimization of heat recovery solutions in mechanical ventilation systems. Heat recovery in ventilation is a highly efficient strategy for reducing heat losses and conserving energy. This study involves the investigation of a ventilation unit installed in an apartment situated in Riga, Latvia, as a practical examination of heat recovery system efficiency within the Latvian climate conditions, representing a cold climate region. The objective of this study was to examine the heat recovery efficiency of the ventilation system in the Latvian climate with variable outdoor and exhaust air parameters, given that the dry heat recovery efficiency is different from the actual heat recovery efficiency. The ventilation unit was equipped with a plate heat exchanger at an airflow rate of 105 m3/h. To evaluate heat recovery efficiency, extensive measurements of air temperature and relative humidity were conducted. The collected data was analyzed, employing statistical regression analysis to ensure measurement reliability and assess correlations. The findings indicated a strong correlation between variables such as heat content, moisture content, and sensible air parameters. It was observed that the actual heat recovery efficiency was 6% higher than the calculated dry efficiency, emphasizing the importance of considering real-world conditions in heat recovery assessments. Additionally, regression analysis demonstrated a positive linear correlation with a coefficient of 0.77, highlighting the dependency between actual measurements and the theoretical model. These quantitative outcomes provide essential insights for optimizing heat recovery systems and enhancing energy-efficient ventilation practices, especially in cold climate environments. Moreover, this study highlights the strong correlation between variables such as heat content, moisture content, and sensible air parameters. Findings offer essential insights for optimizing heat recovery systems and enhancing energy-efficient ventilation practices, especially in cold climate environments.
