EU Taxonomy Assessment for Buildings

IN2 Engineering provides EU Taxonomy technical assessments for Irish developers, investors and asset owners.

EU Taxonomy assessment for Irish building projects

IN2 Engineering provides technical EU Taxonomy assessments for new developments, building renovations and real estate assets in Ireland. We help developers, investors, asset owners and project teams identify the relevant activity and technical screening criteria, build an evidence plan, and assess whether a building activity can support a Taxonomy-alignment claim for finance, CSRD reporting or investment decisions.

As an EU member state, Ireland is directly subject to the Taxonomy Regulation. That doesn’t mean every project has a mandatory Taxonomy reporting obligation, but it does mean the framework applies without the cross-border complications a non-EU project faces. Early, well-documented technical work helps a team test feasibility before design decisions, procurement and evidence gaps become harder to resolve.

What is an EU Taxonomy assessment?

The EU Taxonomy is the European Union’s classification system for environmentally sustainable economic activities. For buildings, an assessment considers a defined economic activity and its current technical screening criteria, not a generic sustainability label applied to a project.

IN2’s role is to provide the building-performance and project evidence analysis needed for that assessment. This can support a client’s wider Taxonomy reporting, lender or investor due diligence, green-finance process, or voluntary disclosure. Legal interpretation, corporate reporting responsibility and confirmation of an undertaking’s minimum safeguards remain matters for the client and its legal, governance and reporting advisers.

When is an assessment needed?

A Taxonomy assessment is commonly requested when:

  • a project is being considered for green finance or EU sustainable finance labelling;
  • an investor or lender requires alignment evidence as part of due diligence;
  • an organisation needs robust project data for its own CSRD sustainability disclosures; or
  • a client wants to compare design options or set a performance brief for a portfolio asset ahead of a voluntary disclosure.

Article 8 of the Taxonomy Regulation requires certain undertakings subject to sustainability reporting under the Accounting Directive (transposed into Irish law via CSRD implementation) to disclose Taxonomy-eligible and Taxonomy-aligned activities. The Disclosure Delegated Act sets the reporting methodology and templates, including turnover, capital expenditure (CapEx) and operating expenditure (OpEx) indicators for non-financial undertakings.

That doesn’t mean every developer, owner, contractor or building project in Ireland has a mandatory Taxonomy reporting obligation. Scope depends on the entity, group structure, applicable reporting regime, financial product and how CSRD has been implemented for that entity type. A project outside mandatory reporting may still be asked for technical evidence by a funder, investor, purchaser or tenant.

The Disclosure Delegated Act was simplified from 1 January 2026, with conditional materiality flexibilities including a 10% threshold for certain non-financial undertaking turnover and CapEx assessments. This isn’t a general project exemption: where an activity is assessed as financially material, it must be assessed in full, and the applicable reporting rules and transitional options need checking for the relevant reporting period.

[DESIGN NOTE: Consider a short “who this affects in Ireland” box: large undertakings and EU-listed companies under CSRD, developers seeking green finance, and asset owners responding to investor due diligence.]

Irish planning authorities and SEAI’s sustainability requirements can also intersect with Taxonomy evidence on some projects, for example where energy performance data prepared for planning or SEAI purposes overlaps with the technical screening criteria for activity 7.1 or 7.2. Where that overlap exists, it’s worth coordinating the two evidence streams rather than producing them separately.

Eligibility versus alignment

Taxonomy eligibility is the starting point. An activity is eligible if it’s described in a Taxonomy delegated act, whether or not it meets the criteria.

Taxonomy alignment is a higher test. Under Article 3 of the Taxonomy Regulation, the economic activity must:

  • make a substantial contribution to at least one environmental objective;
  • do no significant harm (DNSH) to the other relevant objectives;
  • comply with the minimum safeguards; and
  • meet the applicable technical screening criteria (TSC).

A new building may be eligible under the construction activity but not aligned if its energy target, climate-risk response, circular-economy evidence or other applicable criteria aren’t met or can’t be evidenced. Alignment shouldn’t be claimed from eligibility alone, or from one favourable design feature.

Which environmental objectives apply?

The Taxonomy Regulation sets six environmental objectives:

  1. climate change mitigation;
  2. climate change adaptation;
  3. sustainable use and protection of water and marine resources;
  4. transition to a circular economy;
  5. pollution prevention and control; and
  6. protection and restoration of biodiversity and ecosystems.

The applicable route determines which objective the activity contributes to substantially and which DNSH criteria apply. A building activity assessed for substantial contribution to climate change mitigation must still meet the applicable DNSH requirements for the other five objectives. A separate route may apply where construction or renovation contributes substantially to one of the four non-climate objectives instead.

Minimum safeguards sit apart from these six objectives. They concern the undertaking’s procedures for alignment with the OECD Guidelines for Multinational Enterprises, the UN Guiding Principles on Business and Human Rights, the ILO’s fundamental conventions and the International Bill of Human Rights. A project document review alone can’t establish these; they need organisation-level evidence and ownership.

What does IN2’s technical assessment cover?

IN2 reviews the technical information required by the relevant Taxonomy route and builds a clear project evidence trail. Scope is tailored to the activity and design stage, and can include:

  • activity mapping and confirmation of the assessment boundary;
  • a criteria register identifying substantial-contribution, DNSH and evidence requirements;
  • review of energy modelling, primary energy demand and the relevant NZEB benchmark under S.I. No. 183 of 2019 and TGD L;
  • climate-risk and vulnerability evidence, and the response to material physical climate risks;
  • review of water, materials, construction and demolition waste, pollution and biodiversity information against the applicable DNSH criteria;
  • review of lifecycle global-warming-potential information where required;
  • a gap assessment, responsibilities schedule and recommended actions for design, procurement and construction; and
  • an evidence pack or technical memorandum for the client’s CSRD reporting, finance or assurance process.

The exact evidence is criterion-specific. It can include drawings, specifications, energy calculations, building regulations submissions, Building Energy Rating certificates, site and ecological information, climate-risk assessments, bills of quantities, material declarations, waste-management records, commissioning information and procurement evidence. We identify what’s available, what needs developing and who’s best placed to provide it.

How does the assessment support design and approval decisions?

The best time to address the Taxonomy is before key performance, façade, services, material and site decisions are locked in. IN2 can translate the technical screening criteria into an early design brief, test likely constraints against TGD L, and identify the data needed to keep a credible alignment pathway open.

As the design develops, we coordinate the technical evidence with the project team and track changes that affect the assessment. This avoids a late-stage scramble where a project has good sustainability intentions but lacks the calculations, specifications, procurement controls or records needed to demonstrate compliance with the chosen criteria.

A Taxonomy assessment sits alongside other project obligations, not instead of them: planning, building regulations, environmental assessment, SEAI-related energy requirements, life-cycle assessment and the client’s financing requirements. IN2’s sustainability services can be delivered independently or alongside our building-physics and energy-and-infrastructure input, where that supports a coordinated building-performance strategy.

What will you receive?

Depending on the commission and project stage, IN2 can provide:

  • an EU Taxonomy activity and criteria applicability note;
  • a requirements matrix for the relevant delegated-act criteria;
  • a technical eligibility and alignment assessment, with assumptions and limitations stated clearly;
  • a design-stage gap analysis and action plan;
  • an evidence schedule allocating inputs across the client, design team, contractor and advisers;
  • technical documentation for lender, investor or CSRD reporting-team review; and
  • updates as the design, procurement information or completed-asset evidence changes.

Our outputs distinguish clearly between what’s been verified, what’s still required and what falls outside the technical building assessment. They’re built to support informed decisions, not to overstate the status of a project or an organisation’s disclosure.

What information is needed to get started?

Share what you have: project location and stage, intended activity and environmental objective, drawings or BIM/CAD model, energy model and TGD L compliance route, specifications, sustainability targets, programme, procurement route, relevant site or planning studies, and any lender or investor template. For existing assets, share the construction date, Building Energy Rating certificate, operational energy data where available, and acquisition or ownership context.

If the assessment supports a CSRD reporting undertaking, it also helps to know the reporting period, KPI context, group or SPV structure where relevant, and who at your organisation owns governance and minimum-safeguards evidence.

It all starts with a plan. Contact us today to chat about EU Taxonomy for your next project.
