Motivation: Thermal comfort drives

~40% of residential use, with the

smart thermostat promising to

improve comfort, sustainability, and

economics.

Challenge: Current dataset are

insufficient for studying the internal

workings of the building physics.

Vision: Automate current control

systems that interact with building

physics. Built upon user behavior

models in order to keep occupants

comfortable and away from

intervention.

Goal: Create a smart home emulator

that mimics building physics by

bridging information from devices like

Ecobee, Raspberry Pi, Home

Assistant and Smart plugs.

Building energy simulations poorly

capture impact of thermostats and

occupant behavior. This prototype

enables physically testing these

variables without costly field tests.

• Edit, share, and implement advanced control algorithms.

• Integrate emulator into whole building simulation.

• Develop models that interact with building physics, social

cognition and human psychology to create robust human in

the loop infrastructures
