Edwin is a Senior Engineer in Cundall’s Shanghai office. He is a LEED AP and CIBSE Low Carbon Consultant. He is an expert in dynamic thermal, energy and mechanical systems modelling, helping to develop low energy design strategies for a wide range of buildings, including the application of renewable energy technologies. He is particularly experienced in the field of adaptive thermal comfort, and HVAC simulation. In this presentation Edwin puts forward the idea that locality is key, a ‘sustainable’ solution for one location can be a disaster in another. It follows a discussion on the tools of the trade, what and how you need to model in a building to produce a sustainable outcome. He also presents two unique case studies to explain the above.

结束语

28. “Unmanageable complication is the enemy of good
performance. So why are we making buildings
technically and bureaucratically complicated in the
name of sustainability, when we can’t get the simple
things right?”
“冗余的复杂化是优越表现的敌人。 因此我们不能只追
求技术和名义上的可持续，适宜的简单设计亦能达到效
果！”
