ZEPHIR Passivhaus Italia

What ZEPHIR Passivhaus Italia does

ZEPHIR Passivhaus Italia (ZEPHIR SRL) is the Italian reference institute for Passive House (Passivhaus) certification, design, training, and research, operating since 2006 from Pergine Valsugana in Trentino. The company is internationally recognized by the Passivhaus Institut (PHI) in Darmstadt through its affiliate iPHA, granting ZEPHIR exclusive authority in Italy to deliver PHI-developed curriculum (CPHD, CPHT, PEPT), administer certification exams, and issue Passivhaus and EnerPHit certifications for buildings and components. Over nearly two decades, ZEPHIR has trained 5,000+ professionals, certified 200+ projects across 10 countries spanning Europe, North America (Canada), Oceania (Australia), and Asia, and developed the proprietary "Metodo italiano per la Casa Passiva" to adapt international Passivhaus standards to Mediterranean climate contexts.

The company's revenue is generated across five streams: professional training courses (CPHD/CPHT/PEPT modules and bundles priced €320-€3,195, with both on-demand and live formats); Passivhaus and EnerPHit building and component certification fees; software licensing for PHPP (€225-€250) and the DesignPH 2.0 SketchUp plugin (€475), plus upgrade fees and printed manuals; project consulting for designers, contractors, and owners; and publications (the "Passivhaus Book," €25). Core technology is the Passivhaus Standard methodology and PHPP (Passive House Planning Package) energy balance planning, with the DesignPH 2.0 integration into SketchUp enabling direct geometric export into PHPP. ZEPHIR distributes both Italian and English/German language software versions.

The firm serves three customer segments — businesses and craftsmen implementing Passivhaus construction, designers (architects and engineers) requiring CPHD certification, and end users including private owners and public entities (e.g., parishes). Distribution combines a WooCommerce-based e-commerce shop, the Passivhaus Academy self-serve training platform at passivhaus.academy, direct sales for enterprise certification and consulting, and an event-driven channel anchored by the annual National Passivhaus Conference (9 editions at MADE Expo) plus trade fair participation at YED and Klimahouse. The company is a privately held Italian limited liability company with €10,000 share capital and a lean ~10-employee organization.

Broad incumbents

• iPHA (International Passive House Association): iPHA is the global network of Passive House professionals and the umbrella organization that connects ZEPHIR with the Passivhaus Institut. It is a peer organization in the same ecosystem, providing dissemination, training events, and cross-border promotion of the Passive House standard.
• Ente Italiano di Normazione (UNI) - Building Energy Standards: UNI develops the Italian national standards (UNI/TS 11300 series) that govern building energy performance and certification in Italy. While not a direct competitor, it shapes the regulatory environment in which ZEPHIR's certification and consulting services operate and represents the broader standards-setting incumbent.
• Passivhaus Institut (PHI): Passivhaus Institut in Darmstadt is the global originator of the Passivhaus standard and the body that empowers ZEPHIR as an Italian affiliate. It operates the same building/component certification, training (CPHD/CPHT), and PHPP software ecosystem, but at a global scale and as the underlying standards authority.

Direct peers

• GBC Italia (Green Building Council Italia): GBC Italia is the Italian chapter of the World Green Building Council, administering LEED certification and GBC Home/BREEAM-aligned rating systems in Italy. It competes for the same architects, developers, and contractors seeking sustainable building credentials, offering an alternative certification pathway to Passivhaus.
• Logical Soft S.r.l. Logical Soft is an Italian software house specializing in building energy design and compliance tools (Termolog, Impiantus) used by Italian architects and engineers. It is a direct competitor in the building-physics software space and shares the same professional customer base as ZEPHIR's PHPP distribution.
• Passivhaus Austria: Passivhaus Austria (IG Passivhaus) is the national Passivhaus platform for Austria, providing Passivhaus training, certification support, and consulting for the Austrian market. It is the closest geographic analog to ZEPHIR, operating the same PHI-aligned model in a neighboring Alpine country.
• ANIT (Associazione Nazionale per l'Isolamento Termico e acustico): ANIT is the Italian national association for thermal and acoustic insulation that delivers technical training, software tools, and consulting to Italian building professionals. It is a peer in the energy-efficient-construction training and education market and addresses overlapping professional audiences.
• Edilclima S.r.l. Edilclima is a leading Italian developer of building energy performance software (EC700, EC601) used by Italian architects and engineers for energy certification and compliance. It competes with ZEPHIR's PHPP distribution in the Italian building-physics software category and addresses overlapping professional customers.
• Agenzia CasaClima: Agenzia CasaClima is the Bolzano-based public agency that issues the CasaClima/Klimahaus energy efficiency certification for buildings in Italy. It offers a nearly identical bundle of building certification, professional training, and consulting that ZEPHIR offers, making it the closest direct competitor in the Italian market.

Regional players

• PHIUS (Passive House Institute US): PHIUS is the U.S. counterpart to the German Passivhaus Institut, delivering PHIUS+ certification, CPHC training, and climate-specific Passive House standards for North America. It is a regional peer running the same certification + training + software model for a different geographic market.
