FAQ

  • How does this course prepare me for Net Zero regulations?

    The Certified Passivhaus Designer course equips you with the building science and PHPP skills that underpin Net Zero standards worldwide. By training with mosart, you’ll not only meet today’s NZEB requirements but also be ready for 2030’s Net Zero building mandate.

  • How long does it take to complete the course?

    Most learners complete the CPHD On Demand course in 3–6 months, studying around professional schedules. The flexible format means you can progress at your own pace and revisit modules as needed. Exam sittings are available three times a year, allowing you to choose the date that works best.

  • Do I need an architectural or engineering background?

    No. While many participants are architects or engineers, the CPHD course is open to anyone with experience in construction, design, or sustainability. Project managers, developers, and consultants have all successfully achieved CPHD certification. The training is designed to build your confidence, whatever your starting point.

  • How does CPHD compare to other sustainability courses?

    Unlike shorter awareness courses, the Certified Passive House Designer qualification is internationally recognised and directly linked to delivering high-performance, low-energy, and Net Zero buildings. It’s widely seen as the gold standard for sustainable building training, opening doors to career advancement, regulatory compliance, and competitive advantage.

  • Is Passive House the best way to achieve Net Zero?

    Yes. Passive House is widely recognised as the most reliable pathway to Net Zero energy buildings. By focusing on fabric-first design – airtightness, insulation, elimination of thermal bridges, and balanced ventilation – Passive House dramatically reduces energy demand. When this low demand is combined with renewable energy, buildings can achieve true Net Zero performance. This is why Passive House principles are embedded in many NZEB and Net Zero regulations across Europe, making CPHD training one of the most effective ways to future-proof your skills and projects.

  • Can I take the CPHD course if I’m based outside Ireland or the UK?

    Yes. The Certified Passive House Designer (CPHD) course is delivered fully online and is open to participants worldwide. Current students join from Ireland, Great Britain, and across the rest of the world, with the same expert-led teaching, course content, and certification pathway available regardless of location.
