Climate-based daylight modelling (CBDM) is providing the basis for yearlong indoor daylighting
performance predictions. However, evidence of long-term actual daylighting performance of indoor spaces in use is
limited. Since 2013, CBDM has been a mandatory requirement for the approval of school designs that fall under the
UK’s £6 billion Priority Schools Building Programme. Specifying daylight compliance of schools with CBDM metrics
increases the urgency for evidence of actual performance of classrooms. This paper describes a method for long-term
monitoring of classrooms in use. It also identifies the key confounding factors that make the validation of CBDM
metrics in practice a daunting task. Two UK classrooms are used as case studies and are monitored daily for six
months with a 10-minute resolution. Using a robust method, based on High Dynamic Range (HDR) imaging, this
work makes a case for the significance of real world daylighting performance measurements. Moreover it provides an
overview of the first steps toward the evaluation of the practical application of CBDM prediction methods and
metrics.
