Francois founded Greenplan Consultants in 2007 after realising the huge impact buildings have on energy and building material resources. He is a passionate champion for the use of building performance simulation to aid designers and developers to create better buildings. He holds an M-Eng. in Aeronautical Engineering from the University of Stellenbosch and is a registered professional engineer.
Computational Fluid Dynamics
Sewis Van Zyl is responsible, amongst others, for general building performance modelling at Greenplan Consultants. With almost 10 years of experience in Computational Fluid Dynamics (CFD), he has a deep passion for combining the art and science of developing effective CFD solutions for complex natural ventilation and wind flow problems. Sewis holds a Ph.D. in Mechanical Engineering from the University of Stellenbosch. Prior to Greenplan Consultants, Sewis did post-doctoral work at both the University of Stellenbosch and National Renewable Energy Laboratory in the USA.
Kenny Allen is responsible for, amongst other tasks, general building performance modelling. He enjoys the field of Thermo-Fluid Dynamics, and the related topics of power generation and renewable energy systems and technologies. He spent eight years doing research on thermal storage, with a focus on packed beds. Kenny holds an MSc(Eng) and a Ph.D. from the University of Stellenbosch and has also completed post-doctoral research at the same university.
Building Performance Assessment
Sven Oxtoby conducts SANS 10400-XA rational energy assessments and mechanical ventilation designs. Prior to joining Greenplan Consultants, he worked as a mechanical consulting engineer at WSP on Heating, Ventilation, Air-conditioning and Cooling; and previously specialised in thermal and daylight modelling. Sven holds a BSc in Mechanical Engineering from the University of Cape Town.
"I'm completely blown away by the standards to which you and your team are being industry leaders locally and the level of competency and professionalism to which you all work; it's quite inspiring and respectful to tell the truth and has left me motivated to raise my own game where I can.
