Meet Pei - our Sustainability lead & Passivhaus Designer

Pei is a Certified Passivhaus Designer and the sustainability lead at Oran Architecture with a strong commitment to sustainable, high-performance design. Through her accreditation, Pei has gained technical expertise in building physics, energy modelling using Passive House Planning Package (PHPP), and construction detailing needed to deliver buildings that meet the rigorous Passivhaus targets.

Pei is enthusiastic about translating her technical knowledge into practice and making a meaningful contribution to real-world Passivhaus and low-energy building projects. With a sharp eye for detail and a solid technical foundation, Pei believes that building design and building physics should go hand in hand in creating buildings that are not only visually striking and technically efficient, but also socially and environmentally responsible.

What is Passivhaus?

Passivhaus is an internationally proven standard for creating energy-efficient and comfortable buildings. By combining high insulation, airtight construction, efficient ventilation with heat recovery, natural daylight, and passive solar gains, it ensures superior performance while promoting health and wellbeing year-round.

The standard includes a robust quality assurance and certification process, guaranteeing real-world energy efficiency and occupant comfort. The result is reduced operational carbon, lower energy bills, and exceptional comfort and air quality.

At Oran Architecture, we advocate for Passivhaus due to its strong foundation in building physics and decades of proven success across Europe. It bridges the gap between design intent and real-world performance, delivering energy savings without compromising on beauty, resilience, or health. Passivhaus reduces energy demand through intelligent design, ensuring long-term sustainability without solely relying on renewable technologies.
