Curriculum Vitae Ingo Ratsdorf

Ingo Ratsdorf

BE Arch. Reg. Architect NZ & DE, Building Biologist IBN & BBE

I am a registered architect, engineer and building biologist with a passion for sustainability, not only in architecture but in a much broader sense.

My knowledge in ecology, physics and life cycle assessment allows me to develop sustainable procurement and company policies as well as procedures and frameworks.

Our company, envirology, provides me with the required research background.

I have always spent much time outdoors, however my passion for sustainable design was triggered whilst studying architecture at the University of Applied Sciences in Frankfurt, Germany where I developed a special interest in building physics and ecology which I further expanded throughout my career.
Due to involvement in heritage projects back in Germany, I developed a broad knowledge of traditional building techniques which have provided me with a unique insight into modern ecological design principles.

I love hands-on building, particularly with timber, clay and lime.
Am a big fan of Life Cycle Assessment, open source software, hiking, mountaineering and scouting.

I love my family, the passive solar house we mostly built ourselves and the village we are living in.
Our whole family strives to live conscious, consume as little resources as possible and be careful with the products we are buying. We buy organic (not only the food), have own chicken, fruit trees and veggie patch, use LED lights and drive two Toyota Prii.

Sustainability is however not about buying organic or having a solar hot water panel. It’s about a different mindset.
I am educating staff and clients on that matter in an attempt to achieve true sustainability. Not by add-ons, but by creating a deeper understanding of the issues and ultimately a change in behaviour.
