BuiltZERO

Built environment · Digital & sustainability

Build it once.Build it to zero.

BuiltZERO brings digital delivery and sustainability performance under one roof — so the data that designs a building is the same data that certifies it, operates it and proves it.

What we do

Two practices, deliberately joined

Most consultancies sell one or the other. The problem is that the model, the carbon assessment and the certification evidence all describe the same building — and when three firms own them separately, the client pays to reconcile them.

How we work

The single-thread
advantage

  • One team for both halves

    A digital twin without a carbon model is a dashboard. A certification without structured data is a document. We hold both scopes so nothing falls between the two.

  • Upstream of the tools

    We take no software commissions and resell nothing. Our value is the information requirements, standards and governance that decide whether the tools pay for themselves.

  • Evidence that survives review

    Assessors, lenders and tenants all ask for proof. Everything we produce is structured to withstand that scrutiny the first time it is submitted.

The BuiltZERO edge

Eight hours of credit analysis.Fifteen minutes.

ZERA is our AI automation layer for sustainability certification. It does the GIS-heavy, lookup-heavy work that Accredited Professionals do by hand — tracing boundaries, counting and classifying buildings, aggregating transit schedules — and routes every result through professional sign-off.

It automates the counting. Never the accountability.

The process

From brief to evidence

The same three movements whether the output is an ISO 19650 delivery framework or a certified rating.

  1. Diagnose

    We start from how your projects actually run today — the standards in use, the data that exists, the gaps nobody has had time to close.

  2. Define

    Requirements, targets and a sequenced plan tied to live projects and real budgets rather than an abstract future state.

  3. Deliver

    Execution alongside your team, through to audited models, submitted evidence and people trained to carry it forward.

A building is only as sustainable as the data you can prove it with.

The full scope

Everything we are asked for, in one engagement

Scoped individually or combined. Most clients arrive needing one and discover they needed both.

BIM strategy & delivery

ISO 19650-aligned information management, from EIR and BEP through to model audits and handover.

DigitalView

Digital twins

Connecting the as-built model to live operational data so the twin answers questions, not just renders geometry.

DigitalView

AI for the built environment

Applied machine learning and generative AI where it measurably shortens a workflow — not where it demos well.

DigitalView

Digital transformation

Roadmaps, standards and capability building that survive the consultant leaving the room.

DigitalView

Life cycle assessment

Whole-building and product LCA to EN 15978 and EN 15804, used to drive specification, not just to report.

Automating a full LEED credit: from a working day to fifteen minutes

LEED v5 credit LTc3, Compact and Connected Development, is worth six points and is among the most data-intensive in the rating system to evidence. Documenting it by hand means digitising a site boundary in GIS software, generating the 400 m study buffer, counting and classifying every rooftop inside it from aerial imagery, then cross-referencing each nearby transit route's published weekday and weekend timetable stop by stop. A senior sustainability analyst is typically given a full working day to produce it — for one credit, on one project.

Where we work

Registered in Estonia.Working everywhere.

BuiltZERO OÜ is an Estonian company, built remote-first from the start. Certification schemes, information standards and carbon methodologies are international — and so is the way we deliver them. Time zones are a scheduling problem, not a capability one.

Who we work with

Across the whole AEC chain

  • Commercial real estate

    Offices and mixed-use assets where certification, connectivity and operating cost decide leasing outcomes.

  • Developers & investors

    Portfolio-level carbon strategy, due diligence and asset-by-asset improvement roadmaps.

  • Contractors

    ISO 19650 delivery capability, model coordination and handover data that satisfies the client's information requirements.

  • Design practices

    Embedded BIM management and LCA support that scales with the workload rather than the headcount.

  • Public & institutional

    Estate-wide digital standards, decarbonisation planning and evidence for public reporting obligations.

  • Somewhere else in the chain?

Our story

Built from the model up

BuiltZERO started from a pattern we kept seeing on projects: the digital team and the sustainability team were modelling the same building, at the same time, and never speaking. The carbon assessment was rebuilt by hand from drawings that a federated model already described perfectly.

We founded the company to hold both scopes — so structured information feeds the assessment, the assessment informs design while it can still move, and the evidence trail is a by-product of the work rather than a second project.

What we hold to

  • Evidence over assertion

    Every recommendation traces back to a model, a calculation or a standard. If we cannot evidence it, we do not claim it.

  • Early, where it counts

    The decisions that move carbon and cost happen long before certification. We would rather be in the room at concept than auditing at completion.

  • Vendor-neutral

    We take no software commissions and resell nothing. The tool recommendation you get is the one we would use ourselves.

  • Capability, not dependency

    The engagement should leave your team more capable than it found them. We write the standards down and train the people who inherit them.
