Void depth treated as a primary system-selection constraint.
Each system is assessed by the ceiling void it needs (from ~150 mm lighting zones up to 600-1000 mm for deep FCU runs) against the floor-to-floor available, since void depth often decides feasibility in a constrained or heritage shell. Treating void as a primary constraint avoids late, costly coordination clashes.
This is a design-process discipline rather than a discrete product: it proposes treating available ceiling void as the primary filter when selecting MEP systems, since the gap between structure above and ceiling below — from 150 mm in a tight lighting zone to 600–1000 mm for deep FCU runs — often determines which systems are physically possible before any other criterion is applied. The logic is sound on constrained sites, particularly heritage shells where floor-to-floor heights are fixed and cannot be renegotiated. Framing void as the first constraint rather than a late coordination check avoids the well-known pattern of system selection proceeding in isolation from spatial reality, only for clashes to emerge at detailed design when they are expensive to unwind. There is no deployment evidence on record and the approach carries no quantified performance claim — it is a coordination methodology whose value lives entirely in how rigorously it is applied in practice. The risk for a specifier is not that the idea is wrong, but that adopting it requires genuine multi-discipline coordination from the earliest stage, which in practice means a project culture and programme that support it.
