Passive House Architects & Sustainable Design

MosArt are Ireland’s leaders in Passive House architecture and sustainable building design, delivering high-performance NZEB buildings since 1993

Understanding

Architecture both shapes the way we live now and impacts our planet into the future. As Passive House architects, our deep understanding of building physics helps us design homes, buildings and urban spaces that are not only visually striking but also environmentally responsible, energy-efficient and healthy for the people who live and work in them.

Adaptability

We deliver world-leading, low-carbon sustainable building design and architectural solutions, partnering with developers and house builders in various capacities – from full turnkey design to seamlessly integrating into your existing zero emission building design team.

Vision

As Ireland moves toward Zero Emission Building (ZEB) design, choosing a ZEB approach gives you a competitive edge while offering occupants lower running costs, greater comfort and a more sustainable future. Our passion for innovation and sustainable building design ensures your projects are both forward-thinking and environmentally responsible.

Expertise

Our expertise, gathered over 30 years working in this industry, enables us to create spaces that lead the way in sustainability, moving towards Zero Emission Buildings (ZEB) as the future of Passive House architecture in Ireland.

FAQs

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.
