Indoor air quality is a crucial component of green building because it affects all other ecological aspects of the building, such as the branches of a tree. It helps to maintain green technology, building materials and the people inside them for optimal health. Indoor air quality (IAQ) influences human health, productivity and well-being. Green buildings are believed to have better IAQ.
“Sick Building Syndrome” (SBS) describes a set of nonspecific symptoms experienced by occupants due to the time they spend in a building with poor IQ. Therefore, this study was carried out to evaluate the IAQ in green buildings and compare it with that of conventional buildings. The prevalence of SBS in both types of buildings is also being studied. In five pairs of green and conventional buildings, comfort parameters (temperature, &, relative humidity) and indoor air pollutants were measured using monitors.
The analysis was performed with SPSS16 and included Mann Whitney for the concentrations of contaminants in the IAQ and Chi-square for the prevalence of SBS. Similar indoor air quality was found in both types of buildings. The average temperature, CO2 and formaldehyde were statistically lower in green buildings. The prevalence of SBS was found to be 38.1% in green buildings and 53.1% in conventional buildings.
Therefore, to conclude, the poor maintenance of the green building has no additional advantage in terms of the occurrence of SBS. Indoor air quality is a key area of focus for the World Green Building Council (WGBC), which works to improve human health and reduce the environmental impact of built environments. By combining IoT sensors and advanced analysis software, you can take significant steps to improve indoor air quality in green buildings. These can be invaluable resources for green building managers seeking to develop effective strategies that improve air quality.
With this background, the present study was carried out to measure the levels of indoor air pollutants (PM10, PM2.5, CO, CO2, NO2, SO2, ozone, NH3, formaldehyde, total volatile organic compound) and climate factors (temperature and relative humidity) and evaluate their compliance with international indoor air quality (IAQ) standards in green and conventional buildings. This could be because indoor environmental quality only receives 12% of weight in the classification system for green buildings and, therefore, once certified, less importance is given to maintaining its “greenery”. Green construction involves principles of efficient use of resources, a reduction in environmental degradation and pollution throughout the life cycle of the building. Many of the best practices are more easily implemented through the use of cutting-edge technologies to regulate air conditioning and purification systems, allowing green buildings to introduce fresh air and, at the same time, filter out harmful microbes and particles.
However, achieving this requires going beyond established green building guidelines; it means understanding and implementing specific best practices for air quality. Green buildings promote innovations such as the use of fly ash, LED lighting, composting, toilets, rainwater collection, etc., designed to improve people's lives and health and, at the same time, protect the environment. In other words, just because a structure is designed in accordance with green building standards doesn't necessarily mean that it offers greater health and safety protection. The three most common symptoms in green buildings were cough (33.3%), runny nose (32.1%) and sore throat (27.4%).
The evaporation of chemical vapors from building materials or furniture is a potential cause of indoor air problems in modern buildings. He compared these measures to conventionally built residential buildings, following the requirements of the Green Building Tax Credit (GBTC) and the Leadership in Energy & Environmental Design (LEED) in New York. The control of emission sources, ventilation and the measurement of indoor air are the three main ways used in green building schemes for the management of IAQ. The objective of this article is to analyze how and to what extent indoor air quality (IAQ), as a subset of the IEQ, is taken into account in green building certifications around the world.
