Maintenance Stage

Cleaning is one of the important activities during the operation and maintenance stage to any type of core business. Schools nowadays are looking seriously at the cleaning aspect as they realize the availability of health and environmentally friendly facilities that encourage academic performance and staff welfare. These concerns are due to the conventional cleaning practices and products used to keep the school clean. The cleaning contractors are responsible to understand that chemicals with high levels of volatile organic compound (VOCs) emissions and other carcinogens plus dust from poorly filtered vacuums can have a negative impact on the health of students, staff and janitors. Thus, it is a good time for the building managers to make a move to green cleaning practice in school, as a rising number of green cleaning products that are much more effective are available. This study was hence conducted to identify the critical benefits that can be gained through the implementation of green cleaning practice in Malaysian school. Twelve benefits were identified from the literature, and a questionnaire survey that involved green cleaning experts was carried out. Frequency analysis and Importance Index calculation were performed to rank the benefits. The result indicates that “improve indoor air quality (IAQ)” and “provide a safe and healthy environment to occupants and janitors” are the most important benefits of green cleaning practice during operation and maintenance stages in Malaysian school. The findings of this study can provide a significant contribution to the built environment industry. By knowing the benefits that can be gained through green cleaning implementation, efforts can be carried out to explore measures that can be taken to implement the green cleaning practice in Malaysian school or other types of building.

Due to unprecedented urbanization, UAE had built many new residential projects with poor choices of material and ventilation. This social phenomenon is leading UAE to Sick Building Syndrome (SBS) faster than any other countries. The Dubai Municipality regulates the indoor air quality with strict stipulation, but the detailed regulations are still insufficient. The objective of this paper is to measure the indoor air quality of new residential projects in Dubai to suggest the improvement of the regulations for indoor air quality. As a methodology, a field survey was conducted to investigate the status of indoor air pollution in residential buildings. Based on the field survey data, lab experiments for building materials were conducted and a computer simulation on radon gas was conducted. The result had shown that radon gas was mainly detected in new townhouses and labor camp houses, and its concentration was found to exceed the standard. Volatile organic solvents (VOCs) and formaldehyde (CH2O) were mainly detected in showhouses and new townhouses, and the concentration distribution was about 10 times higher than that of outdoors. It was proven that emission concentration of radon gas from various building materials were detected, and the order was red clay, gypsum board, and concrete. Volatile organic solvents (VOCs) are mainly detected in oil paints and PVC floor and the radiation amount of all pollutants increased with temperature increase. In computer simulation, it was found that a new townhouse needs a grace period from 20 days to 6 months to lower the radon gas concentration by 2 pCi/L. This study will serve as a basic data to establish more detailed regulation for the building materials and improve the IAQ standards in Dubai.

Volatile organic compounds (VOCs) are the main source influencing the overall air quality of an environment. It is a well-known fact that coated furniture units, in the form of paints and varnishes, emit VOCs, reducing the air quality and resulting in significant health problems. Exposure time to such compounds is also an important parameter regarding their possible health effects. Such issues also have a greater influence when the exposure period is extended. The main objective of this study was to review some of the important factors for the emission of VOCs from coated furniture, from the perspective of material characteristics, as well as health concerns. Some methods for controlling VOC emissions to improve indoor air quality, from the point of view recent regulations and suggestions, are also presented in this work.

Interdisciplinary Character

The main research hypothesis put in the article is: Populist parties have a negative impact on the functioning of liberal democracy in Poland. The article attempts to characterize and define the main criterion distinguishing populist parties and anti-system movements against the background of standard political parties. The article also attempts to characterize the process of functioning of liberal democracy in Poland. The text has an interdisciplinary character, the research problem has been analyzed from a political, sociological and philosophical perspective. While verifying the hypothesis put in the work, it was noticed that there is a high probability that the election success of populist parties and movements had a negative impact on the process of functioning of liberal democracy in Poland after the parliamentary elections. An attempt to verify the research hypothesis can make a significant contribution to further studying the functioning of the party and anti-system movements in the process of electoral rivalry in Poland.
