“…We are generally following the characterization framework of life-cycle impact assessment (LCIA), which is rooted in toxicological and epidemiological research, and has been widely applied in studies of outdoor ,,,,,− and indoor air pollution, particularly inside or near dwellings. − LCIA considers many parameters, but the one that is most similar to the HI is the EF, which has the units of DALY / kg . The HI can be related to the EF using a breathing rate (BR), which can be assumed to be constant. normalH I k , i = E F k , i · normalB normalR BR is a standardized annual breathing rate of 5402 m 3 /person/year. − …”

This study presents a health-centered approach to quantify and compare the chronic harm caused by indoor air contaminants using disability-adjusted life-year (DALY). The aim is to understand the chronic harm caused by airborne contaminants in dwellings and identify the most harmful. Epidemiological and toxicological evidence of population morbidity and mortality is used to determine harm intensities, a metric of chronic harm per unit of contaminant concentration. Uncertainty is evaluated in the concentrations of 45 indoor air contaminants commonly found in dwellings. Chronic harm is estimated from the harm intensities and the concentrations. The most harmful contaminants in dwellings are PM 2.5 , PM 10−2.5 , NO 2 , formaldehyde, radon, and O 3 , accounting for over 99% of total median harm of 2200 DALYs/10 5 person/year. The chronic harm caused by all airborne contaminants in dwellings accounts for 7% of the total global burden from all diseases.

“…As such, several countries have agreed on the necessity of developing and implementing a novel sustainable energy paradigm in the building, transport, and industrial sectors. For this reason, novel pillars of development for the future and a sustainable energy system have to be varied and flexible, such as the waste to energy paradigm [4], a reduction in energy consumption, the circular economy [5], improved quality of life for people [6], pollution and climate change adaption [7], carbon neutrality with the overall goal to reach zero emissions by 2050 [8], etc. To increase the penetration of renewable energy into society, significant care must be taken with issues related to the management of the excess production of renewable electric energy [9], which leads to several severe issues in terms of grid management [10].…”

“…For instance, there is a significant focus on examining IAQ in renovated and retrofitted residential buildings [3][4][5][6], while other studies delve into the impact of the age of construction on IAQ [7][8][9][10]. The construction type itself has also been a subject of studies [11,12] concerning its influence on IAQ, with recent attention directed toward exploring the IAQ levels in high-performance and green buildings [13][14][15][16][17].…”

Adverse health effects can arise from indoor air pollutants, resulting in allergies, asthma, and other respiratory problems among occupants. Concurrently, the energy consumption of residential buildings, particularly concerning heating, ventilation, and air conditioning (HVAC) systems, significantly contributes to global energy usage. To address these intertwined challenges, heat recovery ventilation (HRV) has emerged as a viable solution to reduce heating and cooling demands while providing fresh ventilation rates. This study aims to investigate the indoor air quality (IAQ) of an experimental tiny house building equipped with an HRV unit by simulating real-life scenarios contributing to IAQ. The research evaluates the effectiveness of HRV compared to natural ventilation in managing particle matter (PM), total volatile organic compounds (TVOC), formaldehyde (CH2O), carbon monoxide (CO), and carbon dioxide (CO2) levels. This research significantly contributes to the understanding of the different ventilation strategies’ impact on IAQ in tiny houses and offers valuable insights for improving living conditions in a unique building typology that is underrepresented in the research literature.
