The challenge of a generation, but we can get there together.

Innovative and informed building design consultancy

The challenge of addressing climate change is the most pressing of our time, and at QODA we are placing net zero carbon at the centre of our designs.

Buildings are complex, a set of inter-relating systems and components, more like a biological organism than a set of parts. Our building physics and building services teams work together with design partners to reduce complexity and make use of natural energy flows to help regulate buildings, designing out waste and inefficiency.

Our aim is for building users and occupants that are genuinely delighted with their created spaces with zero impact on the natural environment. All human activity should be circular in nature and buildings are a key part of that. We work to ensure that both embodied and operational carbon emissions are zero, or as close to it as is feasible for our clients and their buildings, sites, and campuses.

At QODA we think there is no more important task than the creation of amazing human spaces which, rather than degrading it, contribute positively to their wider natural and human environment.



Chris Swinburn

Chris joined QODA in November 2018 and now leads the Oxford sustainability team. He is responsible for a team of modelling engineers providing energy, thermal, and daylight simulations for buildings, as well as looking at advanced modelling techniques and sustainable design practices. He is passionate about making buildings healthy, comfortable, and genuinely low energy through use of passive design and simple servicing strategies.

Chris has over 10 years’ experience in mechanical services design, building simulation, and low energy building design, for a wide variety of different types of building. He is a certified Passivhaus consultant and played a key part in delivering Oxford University’s first Passivhaus.

Joel Callow

Dr Joel Callow has been designing buildings for natural light for nearly 20 years. Always seeking to balance the art and science of natural light, he has wide-ranging experience across many sectors, working in partnership with creative designers.

Joel utilises climate-based daylight modelling (CBDM) and façade solar mapping to understand how people experience natural light on aggregate – and ensures the building design respects and works with the natural environment’s resources. The result he aims for is happy, healthy people occupying buildings that harness nature to its best effect.
