STTC ENGINEERING S.R.L. - SOCIETA' BENEFIT

What STTC ENGINEERING S.R.L. - SOCIETA' BENEFIT does

STTC ENGINEERING S.R.L. - Società Benefit is a Bergamo-headquartered engineering and architecture firm founded in 2022 by Ing. Daniele Carissimi as Studio Termotecnico Carissimi and incorporated as an SRL Società Benefit in October 2024. The firm delivers integrated design services across four disciplines—energy, electrical, mechanical, and architectural—for civil and industrial building projects, with a stated focus on energy efficiency, building renovation, and sustainable construction. It serves four customer segments: residential (individuals, condominiums), industrial (manufacturing and warehouses), tertiary/commercial (offices, sports and cultural centers), and public administration (schools, hospitals, municipal buildings). Operations are concentrated in Lombardy, with project references spanning Bergamo province and Milan province.

The underlying technology stack relies on BIM (Building Information Modeling) and BEM (Building Energy Modeling) methodology, finite element thermal bridge analysis, and specialized design of full-electric heat pump systems. Core products are organized as four design services (Progettazione Energetica, Progettazione Elettrica, Progettazione Meccanica, Progettazione Architettonica) applied across four sector verticals (Residenziale, Industriale, Terziario, Pubbliche Amministrazioni). The firm is CENED-qualified for APE (Energy Performance Certificate) issuance in Lombardy and holds certifications to bid on public tenders.

The business model is project-based professional services: revenue is generated through fees tied to project scope and complexity, with multi-year contract cadence covering consultation, design, and construction supervision. Ancillary revenue comes from managing incentive paperwork (Superbonus 110%, ecobonus, Conto Termico). Go-to-market is sales-led via direct consultation, public tender participation, professional-network referrals (notably ARPO Studio and Studio Belloni e Associati), and content marketing through the company blog. Customer base is highly distributed across project types with no disclosed repeat-anchor accounts.
