“…Studies have further revealed that those working in a building with inadequate internal environmental quality are likely to suffer from reduced well-being and productivity. Furthermore, buildings with more optimal microclimate quality are typically valued between 3-7% higher when sold or rented, and operating costs are 13-15% lower [5].…”

In order to forecast certain microclimatic parameters in a room, such as relative humidity, it is necessary to collect a large amount of data. For this reason, an electronic system for providing comfortable conditions in a room has been developed, which is based on the becoming largely popular Internet of Things (IoT) technology. On the basis of the obtained data, the future change of the relative humidity in a room can be forecasted, which aims to ensure the health and well-being of its inhabitants. It should be noted that working with large datasets requires more sophisticated methods for prediction, and for this reason, this paper presents results obtained from a modified ordinary differential equation approach for forecasting relative humidity. For the purposes of the study, a program code was developed in Matlab. The resulting predicted relative humidity values are comparable to actual measured values, which would help to improve indoor air quality and provide thermal comfort to occupants.

“…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.

“…According to Che Kasim et al (2015), IEQ is one of the six standards of GBI that are needed to be achieved by building owner to be recognised as a green building in Malaysia. Garnys, as cited by Abdul Tharim and Abdul Samad (2016a, 2016b), describe IEQ as the measurement of key factors that are affecting the comfort and well-being of the occupant of a space.…”

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.
