Lo-fi explorations
By creating 30+ device wireframes and 50+ App wireframes, we defined key elements, ensuring a clear and user-centered design foundation.


Turning inspiration into UI directives
We created a moodboard as a visual representation of the keywords "green and affordable" to inspire our UI design. Starting with over 350+ images, we refined the selection to 70+ and finalized 20 key images that guided our design direction. Based on the moodboard, we established design directives to guide our UI, focusing on color palette, typography, use of negative space, and consistent shapes.
Building a Cohesive Design System
Using our UI Directives, we created a design system with defined colors, typography, and reusable components, ensuring consistency and scalability. Detailed documentation streamlined collaboration and upheld our vision of a green, user-friendly interface.

Schedule
The schedule feature lets users customize daily thermostat settings for comfort and energy savings. With Eco Mode as the default, it automatically adapts to outdoor temperatures, ensuring optimal efficiency without manual adjustments.

Edit Schedule
The edit schedule feature allows users to personalize their thermostat settings by adjusting modes and temperatures for specific days and times.

Custom Mode
The Custom Mode feature lets users create personalized modes to match their unique preferences. Users can define temperature ranges, assign custom colors, and select icons, with the app adapting its interface to reflect the selected mode.

Energy Analytics
The Energy Analytics feature provides users with detailed insights into their energy usage, costs, and trends. It displays data on mode usage percentages, average temperatures, and savings achieved, empowering users to make informed decisions to optimize energy consumption.
