Our approach

Construct an accurate model

Consider the specifics of the house

Consider weather forecast

Consider door and window profiles

Construct a game and compute equilibria (comfort and energy)

Experiments: Improve comfort and save energy (up to 60%)!

Computational expensive (Control computed by an internet service)

Pros and Cons

PROS CONS

• More thermal comfort • User needs to provide information• Energy savings • Relies on stochastic data• Gives user more control options • Internet (security and robustness)

Questions

Do you feel empowered to be able to contribute to energy or emissionstargets for your city or country? (yes, a little, no)

Have you ever thought about the tradeoff between your heating comfort athome and emissions or overall energy use in your city? (yes, a little, no)

Do you think there are technologies that might be able to take complextradeoffs into account? (yes, maybe, no)

How much time would you be prepared to put in to specifying yourpreferences on tradeoffs into your energy control system? (a lot, a little, nomore than setting a thermostat)
