Monitored 30 homes for a year to go beyond what people say to understand what they do Surveyed 2,313 households to quantify how many people use heat in these ways Modelling to quantify the heat this uses Small scale field trial in 12 homes to understand how people use remote and zonal heating controls Usability evaluation of 7 heating controls What people say What people do How much heat this uses How many do this Research approach Consortium lead by: Social research by:

©2014 Energy Technologies Institute LLP - Subject to notes on page 1 How we are using insight One example of how we are using this insight is to accelerate heating control technologies. We have issued two requests for proposals to develop better heating controls and gather robust evidence on how they work in practice. We will use this evidence to catalyse a transition to a lower carbon energy system.

©2014 Energy Technologies Institute LLP - Subject to notes on page 1 Summary The ETI is working with government, industry and academia to harness technologies that will increase energy efficiency and reduce CO 2. The Smart Systems and Heat Programme is building a capability to design and deliver practical, cost-effective, energy efficient, local heat systems. We have started a range of projects to understand what people need heat for and how this could be provided using less carbon. Early evidence reveals the need to improve control within homes and support more strategic local area heat planning. We are actively forming partnerships required to meet this challenge.
