and urban design.
with CEA-4.
What is the energy demand of the site in 2050?
What is the on-site solar energy potential?
How dense can we build if we want to achieve 15% solar penetration?
PV panels on facade? What is the design strategy?
How should we retrofit for minimised emissions?
What is the site's emission timeline?
Which buildings are to be connected to a district thermal network?
Which buildings are likely subject to heat stress?
Want mixed-use? How to programme the site for minimised emissions?
We transfer knowledge for decarbonising cities from such world-leading research institutions as ETH Zürich and Singapore’s Future Cities Laboratory .

*CEA is an urban building energy modeling (UBEM) software and one of the first open-source initiatives of computation tools for the design of low-carbon and highly efficient cities. CEA combines knowledge of urban design and energy systems engineering in an integrated simulation platform. This allows to study of the effects, trade-offs and synergies of urban design scenarios and energy infrastructure plans.
Born and hosted since 2013 at A/S Research Group of ETH Zurich, the open-source CEA has enabled architects, urban designers and engineers worldwide to perform building energy simulations and conduct research on multiple scales from neighbourhoods to cities.
“CEA has been a fantastic tool for research and teaching purposes.”
“We look forward to seeing and applying the upgraded CEA in the upcoming term in the teaching modules of our programme.”
