EU Taxonomy real estate: aligning your office portfolio

Regulation 2020/852: two pathways, six objectives, one top 15% threshold

Taxonomy alignment is not worth 5 to 8% in documentary overcost below 5,000 m² consolidated: for an Asset Manager outside the CSRD scope, Regulation 2020/852 is a losing investment as long as the parent company does not fall under the reporting obligation. Above this threshold, however, alignment unlocks 20 to 50 basis points on Sustainability-Linked Loans and a green premium of 5 to 10% on prime assets (MSCI, Real Estate Climate Value-at-Risk, 2023). Kytom, founded in 2006, structures the diagnosis, DNSH, roadmap and works execution according to the Kytom method in 4 phases over 12 weeks, with ISO 9001 and Qualibat 5311 deliverables, arbitrating between assets where the Taxonomy creates value and assets where it destroys cash flow.

The climate delegated regulation (delegated act of June 2021, supplemented in 2023) sets two alignment pathways for existing office buildings:

Pathway 1, native performance: belonging to the 15% best-performing buildings in the national stock in terms of primary energy, a position justified by a level A or B EPC and a documented Cerema benchmark.
Pathway 2, major renovation: reducing primary energy demand by at least 30% after works, certified by an EPC or an equivalent audit.

The DNSH principle (Do No Significant Harm) requires in parallel not degrading any of the 5 other objectives: climate change adaptation, water, circular economy, pollution, biodiversity. The office sector represents about one third of heated floor areas in France (INSEE, Tableaux de l’économie française, 2024 edition), with an average consumption of around 200 kWh/m².year in final energy (ADEME, Chiffres-clés du bâtiment, 2023).

Our reading differs from the industry consensus on Pathway 1. The ESG advisory doxa presents the top 15% as a given as soon as an A or B EPC is obtained. In practice, across 9 assets reclassified 2022-2024 in the Kytom portfolio, a B EPC delivered in year N can drop out of the top 15% in year N+3 without any works, simply because the national stock is improving. Pathway 1 without a maintenance plan is an illusion of alignment.

At what threshold does Taxonomy alignment become profitable?

Above 5,000 m² consolidated and for a parent company within the CSRD scope. Below that, the documentary cost, of 5 to 8% of the retrofit budget, does not pay off. Above it, alignment unlocks 20 to 50 basis points on Sustainability-Linked Loans and a green premium of 5 to 10% at disposal (MSCI 2023).

Is a level B EPC sufficient for Pathway 1 of the regulation?

No, not durably. The top 15% of the national stock is a relative ranking that changes each year: a B EPC delivered in year N can drop out of the top 15% in N+3 without works, simply because the stock is improving. Pathway 1 requires a level A or B EPC, a documented Cerema benchmark and a performance maintenance plan to secure the position over time; without this plan, alignment remains an illusion.
