Prof. Dr. Brian Norton: Smart cyber-physical renewable energy production and use


To achieve buildings with low energy use and attendant mitigation of greenhouse gas emissions requires changes in the fabric and operation of both existing and new buildings. Highly advanced low heat loss, glazing systems allow large areas of a building fa├žade to be glazed without large attendant heat losses.

However, they require the addition of an ability to switch from transparent to opaque to avoid excessive solar heat gain and to control glare. The use of photovoltaics to power such switchable glazing can lead to smart distributed-controlled adaptive building facades. The design parameters for smart PV self-powered switchable glazing systems for adaptive low energy buildings are presented. An illustrative example of system optimization is given for a particular combination switchable glazing, photovoltaic and battery.
