Casa Zero

What Casa Zero does

Casa Zero is a privately held, bootstrapped sustainability consultancy founded by architect Luiza Franco and headquartered in Belo Horizonte, Minas Gerais, Brazil. The firm operates across three service pillars — Viver (Living), Projetar (Designing), and Empreender (Entrepreneurship) — delivering sustainable architecture consulting, ESG advisory, and environmental education to individuals, companies, schools, and government institutions. Core technical offerings include bioclimatic and biophilic design, LEED certification consulting, retrofit architecture, urban acupuncture, and circular-economy integration, complemented by a proprietary 31-card educational product, the Baralho de Gestos Sutis de Sustentabilidade, launched during the 2020 pandemic alongside sustainability-focused e-books.

The business model is a mix of project-based professional services fees for architecture and ESG engagements, recurring consulting/advisory retainers, product sales (card deck and e-books) through the firm's own website storefront, and revenue from talks, workshops, and lectures. Go-to-market is sales-led and content-led, anchored by an extensive blog, Instagram, LinkedIn, and YouTube presence, direct outreach via website form, email, and WhatsApp Business, and event-driven demand generation through partnerships with entities such as Globo.com, Fundação Roberto Marinho, ArcelorMittal Brasil, SEBRAE, the Prefeitura de Belo Horizonte, Centro Universitário UNA, and FIEMG. Pricing is opaque and quote-based, tailored to project scope.

Operationally the firm is small — approximately five employees — with Luiza Franco as the named founder/manager and Roberto Chafith as partner; the company has no disclosed subsidiaries, no funding rounds, no parent, and no AI/ML technology stack, and revenue is not publicly disclosed. Casa Zero is registered under CNPJ 34.239.021/0001-86 at Rua Groenlândia, 195 – Sion, Belo Horizonte – MG, CEP 30320-060.
