Indoor environmental quality (IEQ) is among six criteria of Green Building Index (GBI) that need to be achieved by building owner in order to recognize their building as ‘green’ in Malaysia. The benefit of IEQ is to create conducive environment for human health. Besides influenced their overall image, leasing and resale value of the buildings, does...

... On other hand, World Green Council stated that green building practices can reduce a building's operating costs by as much as 9 percent, increase building values by 7.5 percent and realize a 6.6 percent increase in return of investment. Figure 1 above demonstrates that the interrelations of the Green features level with occupancy rate and capital value and construction costs. The graph illustrate there are directly proportional and positive impact between green aspects and capital as well as the occupancy rate. ...

... With the continuous development of society, people's living standards and aesthetic abilities have increased, as has the importance of safety and comfort in the residential environment [6]. The quality of ILE has a direct impact on people's daily lives [7], affecting the well-being and satisfaction of residents as well as housing prices [8][9][10]. Thus, exploring the relationship between ILE factors and housing prices is essential. ...

The indoor living environment of residential buildings is an important part of the habitat environment, affecting the living experience and well-being of the residents, which in turn influences the price of housing. However, few existing studies systematically concentrate on the integrated influence of the various elements of the indoor living environment on prices, and even fewer analyze the relationship between the indoor living environment and housing prices of different houses within the same residential quarter from a microperspective. Therefore, we use the Taojinjiayuan Residential Quarter, located in central Guangzhou City, China, as a case study area and analyze the extent and direction of the effect of the indoor living environment on housing prices. The study found that the quantitative evaluation results of the indoor living environment were reasonable. The integrated indoor living environment factors are closely related to housing prices. Orientation, view, and acoustic environment are significantly and positively related to housing prices, which have a different intensity of influence. These findings are beneficial to real estate developers, building designers, and residential users in quantitatively understanding the value of the indoor living environment.
... The number of green residential properties in Malaysia has been steadily increasing (GBI, 2013). According to Kasim et al. (2015), the housing sector's need and demand were excessive, particularly in urban areas. This is due to the increasing demand for sustainability in building design and construction (Uche et al., 2013). ...
The number of green residential buildings in Malaysia is on the rise trend. However, there is an imbalance in the amount of green residential buildings available in main cities. Why do things like this happen? Is there a lower demand for green residential buildings in Malaysia's other main cities? Are potential homebuyers aware of the elements of green residential buildings? Therefore, this research was conducted to identify the demand for green residential building and to investigate potential homebuyers' awareness towards the elements of green residential building. The city of Ipoh, Perak, was chosen as the study's focal point, and Ipoh residents with good professions were chosen as respondents. This is because Ipoh has less green residential buildings than some other cities in Malaysia. A quantitative approach was adopted. A total of 384 responses were accepted for analysis. The collected data were analyzed using frequency analysis and the relative importance index (RII). According to the data, the majority of potential homebuyers in Ipoh, Perak, are aware on the elements of green residential building and are willing to purchase it in the future. This indicates that this residential concept is in high demand in the Ipoh market. Ipoh residents are also well aware of the elements of a green residential building. Hence, developers and the state authority would be able to increase the number of green residential developments in Ipoh.
... Material conservation contributes to economic sustainability by helping to reduce the expenses required for the production and transport of materials [9]. Rahman [31] argues that buildings with optimized indoor environmental quality are valued ~3-7% higher for sale and rental, and operating costs are 13-15% lower. Factor 4: ...
... Also, the fact that people spend about 90% of their time indoors [2,3] has made the implications of the indoor environment very important to designers. The benefits of an appropriate indoor environment have been documented by research [4][5][6][7]. As such, organisations strive to create the appropriate indoor environments for workers. ...
In this paper, we investigated the reason(s) why natural ventilation is not as popular as air-conditioned or mixed-mode ventilation systems in Green-rated office buildings in New Zealand. To achieve this, we had three objectives. Firstly, we reviewed the Green Star criteria for thermal comfort in office buildings to ascertain which ventilation system the NZ Green Star rating tool promotes. Secondly, we ascertained the perception of occupants in office buildings regarding thermal comfort. This was followed by an interview with building experts regarding factors that affect the use of natural ventilation in New Zealand offices. The findings showed that the NZ Green Star thermal comfort criteria encourage the use of mechanical ventilation over natural ventilation which results in designers opting for air conditioning systems in office designs. We observed that occupants of naturally ventilated spaces were least satisfied with the thermal comfort of their offices when compared with occupants of mixed-mode and air-conditioned offices. This study fulfils the need to encourage the use of natural ventilation in office environments by designers and building owners. Further study on other aspects of the indoor environment quality that is related to naturally ventilated systems such as lighting and noise is required in a bid to ascertain its viability in office environments.
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.
