The Indoor Environmental Quality (IEQ) refers to the quality of indoor spaces in relation to the health and well-being of users. IEQ is a holistic concept considering various components of the overall indoor comfort: thermo-hygrometric, lighting, air quality and acoustics. Each component is described through specific performance indicators and benchmarks. The quality of the built environment is assessed at different stages from design to operational phase. The scientific literature reports several case studies related to the assessment of the individual components of the IEQ Tools aimed at the evaluation of the overall IEQ. The paper proposes an assessment tool based on the SB Method (Sustainable Building Method) and the Multi Criteria Analysis for the evaluation of IEQ during the operational phase of a building. Each component of IEQ is analysed through objective indicators and calculation methods. The tool provides two main outcomes: a global score expressing the overall performance of the building from the IEQ perspective; quantitative evaluations of all indoor comfort components through monitoring and measurement of the environmental variables. The above contributes to select intervention areas to optimize indoor design and to identify technologies aimed at ensuring the best IEQ levels for users at the operational stage. The system was applied to an open-plan working space of an office building. Monitoring activities and measurements are carried out to detect the indoor and outdoor variables affecting the IEQ. All aspects of IEQ were analysed and quantified so to evaluate the overall performance of the building and provide data to improve the working conditions.

Despite the rapid growth in the number of LEED-certified homes, little data is currently available about the actual effects of LEED-certified affordable homes. The purpose of present study is to conduct a comprehensive performance evaluation for LEED-certified Habitat for Humanity residences in terms of (1) energy efficiency, (2) indoor environmental quality, (3) health impact, (4) residential satisfaction, (5) quality of life, and (6) environmental attitudes and behaviors. A case study was conducted with 15 households living in LEED-certified Habitat for Humanity homes in Kent County, Michigan using observation, in-depth interviews, and surveys. Findings revealed overall housing satisfaction was very high although some residents indicated lower satisfaction with their neighborhood. Most of case study homes had 30-50% lower electricity and natural gas bills. Most participants were satisfied with indoor environmental quality (IEQ) including thermal comfort, indoor air quality, amount daylight, quality of artificial lighting, and acoustical condition. Most participants agreed that since moving into their current homes they have experienced improved family relationships, better health conditions, more positive attitudes, and better performance of their children. The major findings of this case study support the positive effects of LEED-certified low-income homes on residents’ behavioral, social, and psychological aspects of well-being.

This study was done to investigate the relationship between indoor environmental quality and prevalence of Sick Building Syndrome in six small offices inPenangIsland. Indoor environmental quality measurement was conducted according to relevant standards. There are totally Sixty workers were selected to participate in an electronic questionnaire survey. Questionnaire was used to record the comfort level of respondents in the case studies and level of sick building syndrome faced by respondents. Through indoor environmental quality measurement, it is found that most of the offices facing the lighting and noise problem. The result from the questionnaire shows that in overall, the occupants satisfy with their working environment in term of indoor environmental quality although the result also shows the opinions of occupants on dissatisfaction on certain indoor environmental parameter according to case study. The study also found that most of the occupants feel drowsy and fatigue when they work within the offices. Besides, due to the difference of the indoor environmental quality of the buildings, the occupants are suffered from different symptoms of the sick building syndrome.

Decent quality of indoor air is important for health and wellbeing of building users. We live, work and study in indoors of various types of buildings. Often people are exposed to pollutants at higher concentrations than these that occur out-doors. Continual investigation of indoor air quality is needed for ensuring comfort and healthy environment. Measuring and analysis of occurrence of physical, chemical and biological factors is the first step for suggestion of optimization measures. Inside school buildings there are often inadequate indoor climate conditions such as thermal comfort parame-ters or ventilation. The aim of this study was determination of indoor environmental quality in selected offices in the building of elementary school in Slovakia. The values of operative temperature were not within the optimum range of values for the warm period of the year in one of the monitored offices. The intensity of illumination was lower in the two offices. Low levels of particulate matters were measured except the one office where permissible value was exceeded by 7.6%.

Purpose This paper aims to identify the indoor environmental quality in an affordable housing, as well as the health condition of users. Furthermore, it aims to find the relationship between quality of the indoor environment (IEQ) and sick building syndrome (SBS) and the satisfaction level of the occupants towards the IEQ factor, as well as the importance of the factors in the occupants’ view. Additionally, the purpose of this pilot study is to validate the questionnaire and identify the possible outcome of this research for the main study. Design/methodology/approach There are a few methods to achieve the objective of this paper: first is by literature review and second is by a survey. There are two types of survey made: observation survey and questionnaire survey. The purpose of observation survey is to survey the surrounding and the condition of the apartments, while questionnaire survey was distributed to the respondents in the affordable housing area. Next, is analysis and discussion of the survey, and finally, summary. Findings Aside from achieving the validity of the questionnaire survey, the results of the survey have found that the respondents are dissatisfied with the noise and glare level, as well as the amount of artificial lighting in their unit. Additionally, they have rated health, ventilation and amount of air movement as the most important IEQ factors. More importantly, the occupants have experienced the symptoms of SBS and the health condition of the building occupants. The results show that the most frequent symptoms affected the respondents are fatigue, dizziness and a headache. Originality/value This paper has indicated the IEQ in the affordable housing and identifies the health risk of occupants, specifically in Malaysia.
