Daylighting Assessment of a Heritage Place of Instruction and Office Building in Alice, South Africa

Mitigation of post-occupancy building energy consumption has resulted in the change design to utilise ambient weather factors for indoor thermal conditioning and lighting. This increased construction new buildings with large glazing façades reduced adaptive use heritage as they are considered not designed meet modern requirements. paper evaluates daylighting performance a place instruction office building. A quantitative research approach based on information simulation tools was adopted. Autodesk Revit 2021 Integrated Environmental Solutions Virtual Environment (IESVE) were used modelling simulating performances. The building’s annual daylight analysed climate-based shows that points spaces within UDI300-2000 more than 50% occupied period (07h00 17h00) year. sDA300,50% found be 100% most spaces, which is favourable daylit space according Illuminance Engineering Society North America (IESNA). Further, discomfort glare analysis revealed imperceptible, an average probability 21.2%. 1:14 window–wall ratio contributes relative orientation without constituting visual discomfort. Overall, level meets IESNA requirements imperceptible glare.
