Research Interests

Based at PassivSystems as part of a TSB funded Knowledge Transfer Partnership, my work will be to persuade home-owners with the company's domestic Advanced Heating Controls to save energy - and to find ways of increasing home-owners' engagement with the service and product.  

Keeping homes warm and with plentiful hot water is by far the largest use of energy in homes, and is also the largest potential source of energy savings.  Conventional heating systems ask home owners to set heating schedules for when the boiler should come on and go off, and the home owner has to guess or use trial and error to set this time so the home is comfortable when they are in, and so there's enough hot water when they need it.  PassivSystems' product however learns how quickly a home heats up and cools down and when and how much hot water is used, and will work out when to fire the boiler so the home is warm just in time for when the home-owner is in, avoiding wasteful heating when they are scheduled to be out or away. 

Making domestic heating more efficient has wide scale benefits by reducing carbon emissions, helping the UK meet difficult targets and potentially helping improve equity in society by reducing fuel poverty.  At a smaller scale, helping home-owners to make savings in their energy use frees up income that can be used towards other ends, which is a benefit for all home owners, not just those in fuel poverty.  Most heating controls are left on the factory-default schedule however, and additional savings and improvements in comfort could be made if the heating schedules more closely matched the home-owners' actual occupancy.  The first challenge is to facilitate home-owners interacting with their heating systems, so that they match their heating schedules to their daily lives.  After that, how can we supply homeowners with information they need to make decisions about their energy usage, and give them the tools to support sometimes difficult behaviour changes that energy saving entails?
