“…Minimal air renewal rates, based on the overall room/building volume, for different activity sectors and occupancy rates, can be found in the applicable regulations [39,40]. However, indoor air quality is constrained not only by the renovation rate of fresh air from outdoors, but also by the quality of atmospheric air that is brought inside [41]. In densely populated cities or industrial regions, where atmospheric air quality is often very poor, these criteria and/or recommendations are not adequate.…”

Low indoor air quality is an increasingly important problem due to the spread of urbanization. Because people spend most of their time inside, poor indoor air quality causes serious human health issues, resulting in significant economic losses. In this work, the current state of affairs is presented and analyzed, focusing on the current problems and the available solutions to improve the quality of indoor air, and the use of nature-based solutions. These involve the cultivation of microalgae in closed photobioreactors. In these systems, photosynthetic organisms can capture CO2 and other pollutants generated in indoor environments, which they use to grow and develop biomass. Several possible layouts for the implementation of microalgae-based indoor air cleaning systems are presented, taking into account the systems that are currently available at a commercial scale. A critical analysis of the microalgae indoor purification systems is presented, highlighting their advantages and disadvantages, and suggesting potential improvements and future lines of research and development in the area.

“…It is noteworthy that the CO2 level in mixed-mode buildings under natural ventilation operation was predominantly lower compared to other building ventilation types. In general, the required ventilation rate and CO2 concentration are specified as adequate indoor air quality criteria, although there is no common index according to national and international standards [5]. In Brazil, ANVISA Resolution 09/2003 [35] specifies 1000 ppm, i.e.…”

“…Nowadays, it is estimated that people spend 60% to 90% of their time in indoor environments such as residences, educational institutions and offices [1][2][3]. In this way, it is important to study indoor air quality and its effects on thermal comfort since they are related to users' satisfaction, performance and health [4][5][6]. In fact, research has shown that high concentrations of pollutants have direct and indirect adverse health effects since air-conditioned environments can contribute to respiratory and cardiovascular diseases [7,8].…”

Since people spend most of their time in indoor environments, the objective of this work was to study indoor air quality perception and its effects on users’ thermal comfort. Based on previous data from a building with a central air-conditioning system and two mixed-mode buildings located in the humid subtropical climate of Florianópolis, southern Brazil, statistical analyses were performed. Each user subjective answer obtained through a questionnaire was combined with the corresponding environmental conditions – measured using microclimate stations, a portable thermo-anemometer and a CO2 analyser. Results showed that improvement in air quality was associated with the reduction of air temperature and humidity ratio. Also, there was a significant influence of thermal, air movement and humidity sensation and acceptability of air quality perception. Users felt more satisfied or neutral with air quality for being in thermal comfort, and not because of the CO2 level – which means that air quality perception is influenced by factors other than CO2. This study recommends the implementation of an air exchange device in split air-conditioners with air recirculation used in mixed-mode buildings in Brazil. It is important to provide suitable indoor ventilation to reduce pollutants concentration, ensure good air quality and prevent respiratory diseases.

“…It was found that the main difference of the adaptive comfort models relies on the choice of outdoor reference temperature, the extend of acceptable temperature ranges, and databases related to the field studies. Khovalyg et al [32] extensively reviewed EN 15251, ISO 17772, EN 16798, ISO 7730, ASHRAE 55 (2017), GB/T 50785 (in China), ISHRAE 10,001 (in India), SS 553, and SS 554 (in Singapore) standards, questioning the applicability of their comfort models on regional scales. Carlucci et al [33] reviewed the adaptive comfort models in ASHRAE 55, EN 15251, EN16798, ISSO 74 (in the Netherlands), and GB/T 50785 standards.…”

Overheating exposure over time can lead to discomfort, productivity reduction, and health issues for the occupants in buildings. The time-integrated overheating evaluation methods are introduced to describe, in a synthetic way, the extent of overheating over a span of time and predict the uncomfortable phenomena. This paper reviews the time-integrated overheating evaluation methods that are applicable to residential buildings in temperate climates of Europe. We critically analyze the methods found in (i) 11 international standards, namely,
