Zero Consulting is a Barcelona-headquartered sustainability consultancy (legally registered as Ecotec Enginyers S.L.P.) that advises real estate developers, building operators, and corporate clients on energy efficiency, environmental certification, and ESG strategy across primarily the Spanish market. The firm's core offering is structured around three service pillars: New Construction and Renovation (LEED, BREEAM, WELL, VERDE, and DGNB certification advisory, energy consultancy, life cycle analysis, and commissioning), Existing Buildings (in-use certifications, CRREM-aligned decarbonization plans, green policies, and energy audits), and Corporate ESG (EU Taxonomy verification, ESG strategic plans, and corporate carbon footprint). It supports a portfolio of named enterprise engagements including Decathlon, Lidl, Segro, Roca, Veeva, Ferrovial, Heineken, Catalana Occidente, and Templus, with documented outcomes ranging from 40-75% energy savings to 25-86% water consumption reductions.

The company has developed proprietary technology layered onto its consulting practice: an Environmental Analysis Software Suite for energy simulation, LCA calculation, and solution comparison; a contractor-facing ZeroConsulting Academy training platform delivered via TalentLMS; an Online Sustainability Tracking Application for real-time construction-phase monitoring; and a publicly distributed Zero Consulting Tools platform comprising the Multilayer Construction Solutions Generator, Zero Obra Impact, EPD Search Engine, Space Generator, Space Data Configurator, and Resource Library Manager. It holds LEED Proven Provider accreditation from Green Building Certification Inc. (GBCi), conferring faster correction cycles and quality guarantees on LEED projects. The firm operates offices in Barcelona and Madrid with a registered office in Mora d'Ebre (Tarragona).

Zero Consulting generates revenue through project-based professional services engagements priced via custom quotes, sold through a consultative sales-led go-to-market combining educational content (71+ certification articles, 34+ nZEB articles, 11+ ESG articles), pre-evaluation tools, case study publications, and direct enterprise outreach. Since 2024 it has operated as a subsidiary of Accumin, a global real estate valuation, consulting, software, and risk management group, which provides strategic backing and cross-sell potential into adjacent real estate services clients across Europe and Latin America (including Chile).
