CBDM + dynamic simulation to prove the passive design.
Climate-based daylight modelling and IES dynamic thermal simulation are used to maximise daylit, naturally ventilated space and to verify comfort, CO2 and Part L compliance before construction. Modelling the real climate (not static rules) lets the passive strategy be proven and tuned.
Using climate-based daylight modelling alongside IES dynamic thermal simulation allows the passive design strategy to be tested against real weather data rather than the simplified static assumptions of prescriptive compliance routes, enabling both optimisation and verified compliance for daylight, overheating and energy before anything is built. The value is not speculative — CBDM and dynamic simulation are established tools with a clear evidence base in the industry — but the record frames this as a solution rather than a standard deliverable, which is the honest position: rigorous early-stage modelling is still not uniformly applied on projects where programme pressure favours faster rule-of-thumb approaches. The constraint for a specifier is resource and programme: detailed simulation requires model maturity earlier than many project programmes allow, and the outputs are only as reliable as the inputs — occupancy assumptions, control strategies, façade specifications — which are often uncertain at the stage when the modelling has most leverage. The risk of treating modelling as a box-tick exercise late in design, rather than a generative tool from the outset, is that the compliance outputs are achieved but the genuine passive performance optimisation is missed.
