Fencalc XA2021
Study Compliance One Check at a Time
Text-only courses that help you understand the SANS 10400-XA:2021 workflow across envelope design, fenestration, services and reporting. Start with the calculator logic, then build the evidence pack behind each decision.
Recommended Study Path
Follow this order when you want a smooth self-study route through the compliance workflow.
Confirm orientation, climate context and the assumptions that drive later checks.
2 Check fenestration firstMeasure glazing percentage, U-value and SHGC using the right grouping.
3 Resolve envelope riskWork through shading, roofs, walls, floors and building sealing evidence.
4 Coordinate servicesReview hot water, lighting and air-conditioning requirements beside the envelope work.
5 Prepare the evidence packTurn calculations into review-ready notes with clear limitations and references.
