Some of the most common things people ask us.
Passivhaus (or Passive House) architecture is a rigorous approach to building design that prioritises energy efficiency, comfort, and long-term sustainability. Passivhaus architects use advanced techniques and materials to minimise energy use while maximising indoor comfort, often achieving zero emission building design. Our team of expert Passivhaus architects in Ireland and the UK specialise in creating homes and buildings that meet the highest standards in energy performance. Blending sustainable building design with aesthetic and functional excellence, we champion green architecture in Ireland through thoughtful, future-focused solutions.
A zero-emission building is designed to produce no carbon emissions during its operation, typically by using ultra-efficient insulation, airtight construction, and renewable energy sources. This approach is central to Passivhaus architecture, which aims to drastically reduce a building’s energy demand. At MosArt, our Passivhaus architects in Ireland and the UK are experienced in delivering buildings that meet both Passivhause (also known as Passive House) and zero emission standards. Through careful Passivhaus design, we help create spaces that are not only comfortable and cost-effective to run but also aligned with ambitious climate goals.
With over three decades at the forefront of sustainable building design, MosArt stands as Ireland and the UK’s leading authority in Passive House and zero emission building design. Since 1993, we’ve been delivering high-performance, energy-efficient buildings.
Our difference lies not only in what we build, but in how we educate. As recognised leaders in Passivhaus training, we offer both online and in-person Certified Passive House Designer (CPHD) courses, equipping architects, builders, and consultants with the knowledge to design and deliver truly sustainable buildings.
