Purpose Exposure to poor indoor air in refurbished buildings is a matter of health concern due the growing concentrations various contaminants as result building airtightness without amendment ventilation, or use materials such glue, paint, thinner and varnishes. Recent studies have been conducted measure pollutants assess risks affecting quality life, productivity well-being human beings. However, limited review recently provide an overview state knowledge. This study aims conduct scoping (IAQ) context energy-retrofitted buildings. Design/methodology/approach A systematic screening process based on PRISMA protocol was followed extract relevant articles. Web Science, Scopus, Google Scholar PubMed were searched using customised search formulas. Among 276 potentially records, 38 included final covering period from 2015 2022. Findings Researchers mapped out measured compounds selected found that carbon dioxide (CO 2 ) (11%) total volatile organic among most commonly contaminants. Two trends research including (1) impact ventilative properties IAQ (2) introducing IAQ. Originality/value The contribution this lies summarising evidence measurements buildings, discussing recent advancements, revealing significant gaps limitations, identifying drawing conclusions regarding future directions topic.

A naturally-ventilated operational classroom was instrumented at 18 locations to assess spatial variations of air pollution (CRAP), thermal comfort and ventilation indicators under 10 different scenarios (base scenario without purifier (AP); three single AP scenarios; with two APs same locations; locations). Unlike PM2.5, monitored PM10 CO2 concentrations followed the diurnal occupancy profile.

Children spend significant amounts of time at school, making the school environment a potentially important contributor to air quality exposure. The SAMHE initiative has dual aim: 1) develop and test bespoke citizen science framework for collecting indoor data in classrooms, alongside contextual capable enriching analysis, an unprecedented scale; and, 2) simultaneously use these methods raise awareness among communities regarding their exposure pollution environment. To achieve this aim, project was initiated deploy more than 2 000 low-cost monitors classrooms. A Web App been co-designed with schools support large comprehensive dataset (including buildings' characteristics, operation behavioural patterns) enable students teachers interact gathered school. We present design interface visuals that have 20+ tested 120+ schools. Within one week launch week, 537 had registered join project, writing (just seven weeks later) number grown around 800 This highlights potential novel provide step-change way datasets are national potentially, international level while enabling better manage empowering reduce environmental health risks.

This study aimed explore the role of in reducing pollution at community level Tainan City, Taiwan, using quality sensors street-view imagery. We also collected number road trees around each sensor site identified species that were best absorbing PM2.5. Three greenness metrics used assess this study: two Normalized Difference Vegetation Indices (NDVI) from different satellites Green View Index (GVI) Google Street (GSV) images. Land-use Regression (LUR) was for statistical analysis. The results showed a higher GVI within 500 m buffer significantly associated with decreased Neither NDVI circular Evergreen lower ambient PM2.5, compared deciduous semi-deciduous trees. Because localized changes profoundly affect public environmental equity, our findings provide evidence future greenspace planning its beneficial impacts on pollution.

Aerosols such as dust, pollen, smoke, soot, or viruses in our environment can significantly affect air quality, impacting climate and health. For example, virus transmission through aerosols is an important mode of spread for certain respiratory viruses, including the SARS‐CoV‐2 responsible COVID‐19 pandemic. Numerous measures were proposed mitigating harmful effects aerosol on Though these are effective, they found to have intrinsic disadvantages. Combined intervention promising, with progress being made combining different technologies enhance removal improve indoor quality. While combined layered was previously a rational measure overcome some disadvantages associated individual approaches, there lack availability quantitative experimental data at least many possible combinations from viewpoint number particles removed surrounding environment.
