This paper conformed the indoor air quality evaluation of buildings in Lingui, using the designed evaluation system combined subjective assessment with objective evaluation. By calculating and analyzing the experiment data and survey data, the comfort and the main effecting factors of public buildings in Lingui was put forward herein. Eventually appropriate measures were proposed to improve the indoor air quality.

Quality Evaluation System

This paper presents the thoughts about application of saliency map to the video objective quality evaluation system. It computes the SMSE and SPSNR values as the objective assessment scores according to the saliency map, and compares with conditional objective evaluation methods as PSNR and MSE. Experimental results demonstrate that this method can well fit the subjective assessment results.

This work focuses on indoor air quality evaluation of commercial buildings in Kuantan. Some buildings have been selected to monitor indoor air quality. The research has been carried out only in Kuantan, which focused on hotels and government buildings. Some sample measurements were taken which include air temperature, relative humidity, and air movement, carbon monoxide (CO), carbon dioxide (CO2), ozone (O3), respirable particulate matter (PM 10), formaldehyde and total volatile organic compound (TVOC). In addition, questionnaires were conducted on a number of workers in each building to determine the level of health and illness caused by air in the building where they work. Hence, this study has analyzed the link between the questioner results and the results of indoor air measurements that were carried out. From surveys, it appears there are four buildings that have low air flow, four buildings have a lot of dust and five buildings have a high temperature. In contrast, four buildings have a good indoor air quality.

The paper presents a study aimed at investigating the indoor air quality (IAQ) and people’s perception regarding the indoor environment of schools and public buildings in Timisoara. The indoor air quality monitoring was performed during the cold season, in the period January 2020 – February 2021. Six public buildings – schools and administrative edifices belonging to the municipality were subject of monitoring. An Andersen microbial air sampler was used to enumerate the numbers and different kinds of respirable bacteria and fungi inside of the selected classrooms and offices. The results of the specialized laboratory analyses indicate that the microbiological contaminant counts, expressed in colonyforming unit (CFU/m3), fall within the permissible limits for all monitored rooms. No beta-hemolytic streptococci or Staphylococcus aureus were identified, conditionally pathogenic bacteria for the upper respiratory tract. Most moulds were of the genus Penicillium, without having a pathogenic significance for humans. Occupants’ perception on indoor air quality, thermal comfort, health complaints and symptoms such allergies or respiratory illnesses with possible connection to the Sick building syndrome were surveyed by questionnaire. The findings were analysed and a plan to improve IAQ in the public buildings was proposed, with specific measures to increase the comfort and health of the learning and working environment.
