Indoor Environmental Quality

This workshop session will consist of a series of presentations by members of the Board for the Indoor Environmental Quality – Global Alliance (IEQ-GA). The AIVC is one of the founding members of the IEG-GA, and its representatives have participated in the formation of the Global Alliance as well as active members in planning for the next stage of its development. The Alliance is expected to be an independent international NGO whose members are public or non-profit entities that are involved with advancing knowledge on common indoor environmental quality issues.

As one of the founding partners of the IEQ-GA, the networking with other organisations within the global alliance is for AIVC very important.  
Whereas AIVC has primary a focus on good indoor air quality (by using ventilation) and good thermal comfort during warm periods (by using intensive ventilation), it is clear that an overall approach to indoor environmental quality is important.  

In these three presentations, we review the origins and history of the Indoor Environmental Quality Global Alliance, AIVC’s view of the potential value of IEQ-GA, and directions it is taking and may take over the next decade. 

Indoor environmental quality (IEQ) is generally taken to encompass four main factors: indoor air quality (IAQ), thermal conditions, visual quality, and acoustical quality. Although there is an implicit concern for safety, the predominant metrics all four in standards for design of buildings are based on perceived quality or comfort.

Through history; a large body of research has found a relationship between the IEQ and the recovery of patients in healthcare facilities. IEQ factors include natural ventilation, daylighting, acoustics, materials off gassing, etc... This research is to identify the guidelines to healthy daylighting in hospital buildings. Research methods include grounded theory finding through intensive literature review and analysis of successful international examples.

There is little knowledge on if and how indoor environmental quality influences students’ attendance and productivity. However, this issue has been of growing interest the recent years in the scientific community and results are showing that student learning performance is significantly affected by indoor environmental quality factors. In the present study the learning performance is examined through numerical test scores achieved by primary school students in their classrooms.

This paper reports the effects of air quality and thermal environment on motivation and performance forstudents. The psychological condition of subjects can strongly influence their performance for learning.In this paper, the motivation for learning is evaluated by using a questionnaire as a self-assessmentform. According to the previous research, motivation for learning becomes biased when the learningperformance of the student is measured.

The use of electricity in buildings constitutes around 16% of Singapore’s energy demand. To incorporate energy efficiency measures is one of the key mission to ensure that the economy is sustainable. The recently launched building energy efficiency labell
