Indoor Environmental Quality

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
