Recent Advancements in Ventilation Systems Used to Decrease Energy Consumption in Buildings—Literature Review

Abstract

The need for healthy indoor conditions, the energy crisis, and environmental concerns make building ventilation systems very important today. The elements of ventilation systems to reduce energy intensity are constantly the subject of much scientific research. The most recent articles published in the last three years are analyzed in this paper. Publications focused on the topic of reducing energy consumption in ventilation systems were selected and divided into five key research areas: (1) the aspect of the airtightness of buildings and its importance for the energy consumption, (2) the methods and effects of implementing the concept of demand-controlled ventilation in buildings with different functions, (3) the possibilities of the technical application of decentralized ventilation systems, (4) the use of earth-to-air heat exchangers, (5) the efficiency of exchangers in exhaust air heat-recovery systems. The multitude of innovative technologies and rapid technological advances are reflected in articles that appear constantly and prompt a constant updating of knowledge. This review constitutes a relevant contribution to recognizing current advancements in ventilation systems and may be helpful to many scientists in the field.

Investigation of Thermal Comfort, Productivity and Lighting Conditions in Higher Education Buildings

“…Room users who feel comfortable in terms of temperature are more likely to engage in work, which translates into increased productivity and the quality of services provided. Previously, the authors focused on the phenomenon of the sick building syndrome (Krawczyk et al 2023), while the present paper analyses selected indoor environment parameters and their impact on human sensations due to the importance of this issue in several aspects (Amanowicz et al 2023. The insufficient data available in the literature regarding the analysed research area needs to be supported by new data, which is the aim of the present paper.…”

Model-Scale Reproduction of Fan Pressurization Measurements in a Wind Tunnel: Design and Characterization of a New Experimental Facility

“…Since the 1970s, many studies have highlighted the impact of poor airtightness on building energy consumption. More recently, Amanowicz et al [2] presented new studies that confirm the energy impact of buildings' airtightness. In particular, Simson et al evaluated the infiltration heat losses for two reference cases in Estonia [3] and estimated that they represent, in most cases, 13 to 16% of the total building heat losses but can reach 50% for the highest wind speeds configuration.…”

Evaluation of the Suitability of Using Artificial Neural Networks in Assessing the Effectiveness of Greywater Heat Exchangers

“…Borowski [1] pointed out that this resource is necessary in the context of improving living conditions and ecological development. For this reason, the implementation of efficient and cheap heat recovery systems seems to be a necessity [2][3][4], especially since basing modern energy policy solely on renewable sources may lead to periodic energy shortages [5]. Gualotuña-Gualoto et al [6] noticed that the use of energy irretrievably lost in buildings may contribute to the decarbonization of the economy.…”
