Accounting for the weather in new builds

Overheating in Buildings: Why It’s Still Being Missed Overheating remains a major risk in UK buildings, despite improved modelling and regulation. We explore the gap between design intent, TM59 compliance, Part O, and real occupant experience — including why much of the existing building stock is still vulnerable. Designing for a Hotter Future How CIBSE future weather data are created, common misconceptions, and how engineers should actually use climate scenarios to avoid designing for outdated conditions. Visual Comfort, Glare & Shading Why shading is underused in the UK, why TM59 models both with and without shading, and how human behaviour, glare, and daylight expectations influence real-world performance. Passive First: What Really Works Evidence-backed passive strategies that genuinely reduce overheating — including shading, night ventilation, glazing choices, and layout — versus box-ticking solutions.   Useful Links: Wellbeing and productivity in offices
