Tom is the founder and director of Except, and the visionary force behind its development. Starting Except at the age of 19 in 1999, his vision was to find systemic solutions for our societal challenges by combining science, business, design and communication. His vision shows that we can flourish globally when we integrate environmental, societal, economical and technical aspects at the same time. In the past decades Tom developed over 500 projects pioneering projects for cities, buildings, business, policy, and industry.
Tom has been increasingly recognized as a leader in sustainability thinking, the circular economy and systemic innovation. In 2014 he was elected number 38 of most influential sustainability professionals in the Netherlands by the national newspaper Trouw, and ranked number 21 on the Dutch Sustainable Real Estate awards. In 2017 his initiative, the UCo center for sustainable entrepreneurship in Utrecht opened, bringing together over 150 sustainability pioneers in the first energy neutral, circular and healthy listed heritage building in Europe.
Tom develops the Symbiosis in Development (SiD) methodology that lies at the core of Except’s operations. SiD combines systems thinking, complexity analysis, iterative design thinking and co-creation in multi-disciplinary teams. With SiD Tom leads transdisciplinary teams to develop pioneering solutions that breach the frontier of what's possible. These include solutions for the circular economy, natural capital, smart urban redevelopment, bio-based economy, and resilience research and development.
As director and designer, he's driven Except's bio-based architectural and urban designs, such as the Merredin Algae plant, Shanghai vertical agriculture tower systems and the urban redevelopment of large and small cities around the world. This includes their energy systems, ecosystem services, resource metabolisms, business models and the health and happiness of their people. In 2016 he launched the concept of Catalytic buildings. He spearheads developments ranging from software for supply chain optimization to sustainable agriculture systems such as Polydome.
After his Master in Industrial Design Engineering from Delft, Tom studied Architecture in Australia at the University of Western Australia, and obtained his Masters in Architecture & Urban Planning from Yale University. Tom has worked and lectured in Australia, Canada, China, the Netherlands, Belgium, Italy, and the United States. He teaches as a guest-lecturer in various universities and publishes articles regularly.
The land we grow our food on, water that flows through it, animals and plants living in this environment, and the oceans - the birthplace of life. This, and more, is our natural capital; the value represented by our ecosystems, species, and everything in between that we rely on to persist on this planet. All of our natural systems are declining fast, and this threatens our future. It puts at risk the continuation of any business with a complex supply chain, and jeopardizes the resource availability of any nation.
The Natural Capital (NC) movement attempts to halt and reverse this trend by embedding the value of natural systems into economic systems. This article talks about how Natural Capital works, what the pitfalls and opportunities of such a system are, and how we can accelerate implementation in government and business.

Overal in Nederland kraken wijken en steden in hun voegen; ongeschikt voor de hedendaagse samenleving en niet in staat om zichzelf aan te passen. Een patroon dat al langer zichtbaar is in economieën als Frankrijk, India en Brazilië. Probleemwijken, leegstaande kantoren door faillissementen en arme populaties nemen toe. Er is maar één conclusie: het oude vastgoedmodel is failliet. Rondom de wereld stijgt de vraag naar veerkrachtige en bloeiende wijken, maar hoe ontwikkel je die?
In recent years, global environmental policy has become almost a single-issue arena: most companies and policy makers are seemingly fixated on climate change. Though the fate of our climate is undeniably an extremely important issue, in the context of achieving a sustainable future as a whole, it is just one piece of the puzzle, which cannot even be addressed without adopting a broader perspective.
Our world is littered with the physical remnants of past ideologies calcified in the form of buildings, plazas, and streets. One of the most ubiquitous of these is the result of the conversion of the early Modernist utopian vision into cheap, rapid-to-build housing estates carrying the promise of a “modern” life for everyone. The postwar reconstruction effort saw these housing estates efficiently stamped out all over the Western world.
Nuclear energy has recently seen national policies and public opinion turn in its favor. Governments around the world, including Italy and Sweden, are lifting bans on new plant construction. Not alone in the developing world, India and China are pursuing ambitious expansions of their nuclear power programs.
According to a 2010 International Atomic Energy Agency (IAEA) report, 20 countries without nuclear power plants are expected to have nuclear power on line by 2030 (1). Headlines such as “Nuclear’s Great Expectations” (2), “Power up! The rise of the nuclear option” (3) and “Going Nuclear” (4) attest to a paradigmatic shift from looking at nuclear (fission) energy as a 20th century problem towards seeing it as a 21st century solution. In the Netherlands plans to construct two new nuclear power plants are in an advanced stage, seemingly undeterred by the Fukishima events.
This article documents research on increasing Solar Updraft Tower efficiency by introducing multiple uses, agriculture, urban applications and co-generation of solar energy.
Urban transportation issues can be alleviated by encouraging and enabling a higher degree of pedestrianization and bicycle use.
