What OTEC does

OTEC is a privately held Brazilian sustainability and ESG consulting firm founded in 2008 and headquartered on Avenida Paulista in São Paulo. The firm operates with 11 employees and targets enterprise clients across three primary verticals: commercial and residential real estate developers, construction companies, and infrastructure and urban development operators. Founder David Douek remains actively involved in the business. The firm has accumulated 18 years of experience and reports having served over 18 million square meters of built environment across national and international projects.

The company's technology backbone is its exclusive Brazilian distribution rights to DesignBuilder, an integrated building performance simulation suite comprising a central 3D modeler and 11 specialized modules covering energy simulation (backed by EnergyPlus), HVAC, natural ventilation, daylighting, acoustics, and computational fluid dynamics (CFD). OTEC complements the software with a Revit Add-In for BIM interoperability and a Results Viewer for post-processing. Around this technology stack, OTEC organizes its services into six practice areas: Energy Efficiency (audits, zero-energy building design, ISO 50001), Water Efficiency, Environmental Management (LCA, carbon footprint), Environmental Comfort Assessment, iBIM / Construction & Asset Management, and Certifications advisory across LEED, WELL, Fitwel, EDGE, Envision, and GNFZ standards.

OTEC's revenue model is a hybrid of three streams: (1) professional services fees from sustainability consulting engagements, (2) recurring software resale and licensing revenue from DesignBuilder distribution in Brazil, and (3) training and education services delivered via remote webinars, in-person sessions, and a YouTube tutorial library. Pricing is quote-based and not publicly disclosed, with go-to-market conducted through direct enterprise field sales via phone, email, and website contact. The firm is founder-owned with no disclosed institutional investors, parent company, or funding rounds.
