The granularity is set once the Tile is fixed, which is why [[design-sequence-priority|Building Services is overlaid only after the Leasing Plan]] — a Tile-level climate zone can only be drawn correctly once the Tiles themselves are known. ## Why the Tile is the right unit A [[key-plans-and-tiles|Tile]] is already the smallest geometrically complete leasehold unit Woodfine leases against, sized to the equipment and circulation geometry of a specific professional use. Matching the climate zone to that same unit means a Building Services Collaborator is zoning against a boundary that already exists in the leasing geometry, rather than inventing a separate zoning boundary that has to be reconciled with it afterward. Special Tiles are the one case sized differently — larger configurations built for leaseholds that take up to three-quarters of a floor around the Elevator Lobbies. Because a Special Tile is large enough to function as its own leasehold, it is given a self-controlled climate zone rather than sharing the standard Tile-sized zone. ## What it replaces The standard replaces individual-leasehold environmental control as Woodfine's default. Tenant-level control sounds like a better amenity, and Woodfine tested it. A broad group of Building Services Collaborators working across Canada, the United States, the United Kingdom, and continental Europe independently reported the same finding. Systems built to give individual tenants their own control led to significant maintenance and reliability problems, and the resulting service failures created real dissatisfaction among tenants and their Users. Woodfine's own environmental control is instead run centrally, as part of property management, on the basis that a centrally optimized system outperforms a patchwork of individually run systems and is what a Class-A building's tenants should expect by default. ## Where a tenant can still get more control The default is not absolute. A tenant leasing a full Corporate Office — roughly a full Tile-sized unit on its own, an eighth of a floor at minimum — reaches the scale at which individual environmental control becomes practical to offer. A tenant that wants distribution beyond that can install and pay for its own higher-end systems, provided the installation does not interfere with the building's shared systems. A smaller tenant sharing a Tile with other leaseholds does not have that option and instead escalates a climate issue through the building's tenant-facing service channel or directly with the on-site building manager. ## Consequence for tenant experience and maintenance cost Because the zoning boundary is fixed at the Tile rather than negotiated leasehold by leasehold, the standard avoids the specific failure mode Woodfine identified in individual-control systems: unreliable service driving repeated maintenance calls and escalating tenant frustration. Sizing the zone to the Tile also means the standard travels unchanged with the [[fixed-floor-plates|Fixed Floor Plate]] into every deployment of the same prototype class, rather than being redesigned building by building. ## See also - [[key-plans-and-tiles]] — the Tile unit this standard zones against - [[design-sequence-priority]] — why climate zoning is set only after the Leasing Plan - [[fixed-floor-plates]] — the floor plate discipline this standard travels with - [[geometry-of-sustainability]] — the regulatory-standard approach to building-level operating performance
