ENLITEN

ENergy LIteracy Through an Intelligent Home ENergy Advisor

To reduce carbon emissions from energy use in dwellings by developing a low-cost intelligent home energy advisor that will

provide actionable prompts to households that they can use to save money and energy.

Building Occupant Model

I Understanding of the role of habit in occupants’ energy demand andattitudes to carbon saving.

I drawing on a range of sensing and human data analysis.

In-Building Interactive Tool (iBERT)

I A unique whole building energy model, bringing together the buildingenergy and occupant models.

I Interactive tool to help identify and improve energy habits.I Providing customised, actionable prompts rather than poorly

understood numerical energy estimates.

The Bottom Line

How can we help deliver the full potential of PassivHaus?

I Digital technologies are extremely good at producing information.

I But information 6= feedback.

I Feedback needs to be tailored, meaningful and immediate.

I We need to understand how each household “uses energy” tounderstand what feedback we should provide.
