This paper proposes a visual field observation instrument for assessing the physical condition of building elements that are likely to have significant impact on school buildings’ IEQ.

Buildings are expected to serve their functional requirements throughout their operation and maintenance (O&M). During this phase, building elements such as walls and windows can deteriorate and affect the quality of indoor space they enclose.

Literature review reveals the limited empirical evidence on how physical condition of building elements affect indoor environmental quality (IEQ) parameters such air temperature, especially in schools.

This paper proposes a visual field observation instrument for assessing the physical condition of building elements that are likely to have significant impact on school buildings’ IEQ. This space level condition assessment (SLCA) instrument assesses five main aspects: the main enclosure (e.g. walls and floors); openings (e.g. windows); finishes (e.g. ceiling); electrical (e.g. lamps); and mechanical installations (e.g. air inlet).

Respective elements are assessed using four predefined defect severity and intensity levels. The visual assessment in conjunction with the use of predefined defect severity and intensity levels will minimize the SLCA’s implementation time and its subjectivity. Results of the SLCA will be used to determine the extent to which defects affect IEQ parameters and inform related O&M decisions. The SLCA will be of interest to school managers, and IEQ researchers interested in exploring IEQ and building elements condition relationships.
