What makes mWz different · Dossier D-04

Carbon is a design input, not a closing purchase.

Sustainability added at the end costs money and convinces nobody. Treated as a parameter at the start, it changes orientation, massing, envelope, systems and material selection — where the savings actually live — and it produces the evidence that green-linked lenders and ESG mandates now require. We set the target before concept, model against it at every stage, and verify it after the building is occupied.

01 · PROCESS MAP

How the work moves

Input

Target set

Operational and embodied carbon targets fixed before design begins.

Engine

Designed against

Passive strategy, systems and materials modelled to the target at each stage.

Output

Verified

Assured at completion, then measured in occupation against prediction.

02 · WORKFLOW

Step by step, with the gates that stop it

Diamonds are stage gates. Work does not pass one until its criteria are met — which is what keeps a programme honest when it is under pressure.

01 Baseline and target set

Operational and embodied carbon targets are agreed against a named standard and the local climate and grid, before any design decision constrains what is achievable.

02 Passive and climate-responsive design

Orientation, massing, envelope, shading and daylight resolved first. The cheapest kilowatt-hour is the one the building never needs.

Gate A — Target verified against design

The modelled design meets the stated target. If it does not, the design changes — the target does not.

03 Energy systems and generation

Efficient systems selected and on-site generation, storage and grid strategy sized against the actual demand profile rather than a rule of thumb.

04 Embodied carbon and materials

Structural options and material selections compared on embodied carbon alongside cost and programme, with local supply reality accounted for.

Gate B — Assured against standard

Independent assessment or certification evidence is in place and consistent with what was modelled and what was built.

05 Measurement and verification

Metered performance in occupation is compared with prediction, and the gap is reported rather than quietly closed.

03 · ENGAGEMENT

What we need, what you get

What we need from you

Your target or obligation — certification sought, lender covenant, corporate ESG commitment.
Operational profile — how the asset will actually be used, hour by hour.
Grid and utility context — tariff structure, grid carbon intensity, export rules.
Appetite for capex/opex trade-off — payback period you will accept.

What you receive

Carbon target statement tied to a named, recognised standard.
Energy and carbon models issued at each design stage, not just at the end.
Embodied carbon assessment with material alternatives priced.
Post-occupancy verification report comparing measured performance with prediction.

Publishing the gap between predicted and measured performance is uncomfortable and unusual. It is also the only claim about sustainability that a lender can actually test.
