A breath of fresh air – how can we bring back natural ventilation?



Part of the City Conversations series, this event will discuss whether we are entering an era of passive design and environmental engineering and, if this is the case, how we should prepare for it.

Active cooling systems are the default response to overheating in city buildings. Sealing the envelope to protect the interior from noise, dust and fumes has been the justification. However, many believe that we are entering an era in which the reduced impact of new technologies in cleaner cities – electric vehicles being the prime mover – will change this development dynamic. A greater understanding of the impact of ‘control’ on the wellbeing of occupants is also a driving factor. 


Panelists include:

 – Sue Roaf, Professor of Architectural Engineering at Heriot-Watt University in Edinburgh 

 – Chris Twinn, founder of  Twinn Sustainability

 –  Jack Harvie-Clarke, director of Apex Acoustics

 – Steve Williamson, director and partner at Happold Foundation (Chair)


This talk is free to attend but booking is essential. Registration will be from 6pm and the talk will start at 6.30pm.

'City Conversations' is a series of informative thought-leadership discussions around the big issues that are changing our cities  – growth, technology, resource efficiency and climate change. The conversations will address not only the new and changing infrastructure of cities but also how these are brought about and their impact on the lifestyle and wellbeing of citizens. 

City Conversations are produced by The Happold Foundation with ngenuity Ltd and supported by The Built Environment Trust.
