What Citae does

Citae is a French specialist consulting firm headquartered in Montigny-le-Bretonneux that advises real estate developers, investors, asset managers, social housing providers, tertiary building owners, and public collectivities on energy performance, environmental certification, and sustainable real estate strategy. Founded in 1998, the firm operates 7 agencies across France with 50+ expert collaborators and reports having served 3,000+ clients over 25+ years. The company is a subsidiary of BTP Consultants group.

The firm's service portfolio is organized around six pillars: (1) environmental certification Assistance à Maîtrise d'Ouvrage (AMO) for NF Habitat, HQE, BREEAM, and LEED; (2) energy efficiency services including OPQIBI-certified audits, Decree Tertiaire compliance, Decree BACS advisory, RE2020 thermal studies, ISO 50001 energy management, and B2B energy procurement support; (3) occupant comfort and wellbeing covering acoustics, WiredScore/R2S connectivity, OsmoZ, and WELL certification; (4) VALAE by Citae — a 2026-launched sub-brand providing sustainable finance and ESG advisory across SFDR, EU Taxonomy, CSRD, Article 29 LEC, and ISR labeling; (5) low-carbon corporate strategy including BBCA, BEGES, and CRREM trajectory work; and (6) circular economy (PEMD diagnostics, reuse AMO) and technical/ESG due diligence. The firm holds OPQIBI, ISO 50001, ISO 9001, and ISO 14001 certifications and maintains in-house BREEAM Assessor, BREEAM AP, and Cerqual Referent Technique qualified personnel.

Citae generates revenue through project-based professional services engagements priced by scope, complexity, building typology, and certification level, typically structured as multi-year contracts. Go-to-market is enterprise field sales with consultative selling, supported by a professional website, regulatory content marketing via blog, and a 48-hour expert callback commitment. The firm maintains strategic partnerships with the major French and international certification bodies — Certivéa, Cerqual Qualitel, BRE Global, and Alliance HQE-GBC — which provide anticipatory insight into referential evolution and preferential access to certification workflows. All operations are domestic to France.
