Before and After: Honeywell Prestige 2.0 Thermostat Final Re-design + Design Process Overview

Saturday, December 28th, 2013 | Posted by bhavini.patel



Last week we presented our final re-design of a programable thermostat for Rapid Ideation and Creative Problem Solving. Our problem for 8-weeks was to re-design the existing Honeywell Prestige 2.0 thermostat system. Final Iteration 6 here as well as an overview of the design process and reflections below:

Understanding Complexities

As part of our design research, we engage in a problem space to help us understand the complexities of a system.  So I manually went through each screen of the Honeywell thermostat to create Concept Model 1.  Going through this process helped me zoom in and out of details to conceptualize an Ideal System.

Ideal System

My ideal system informed users about their energy consumption, air quality, incorporated color as part of temperature control and featured the list below.

Features List (should include at minimum)

  • Adjust temperature to warmer / cooler
  • Switch between heating & cooling
  • Turn the system on and off
  • Turn the fan on and off
  • Set / edit a 7 day schedule
  • Interrupt the schedule to adjust the temperature


1. 1950s Honeywell Thermostat by Henry Dreyfuss.  The design was simple but that’s why it was beautiful to me.

2. Nest. Their integration of motion sensors inspired me to completely move away from manually programming a thermostat for while you are away.

3. Less but better… Dieter Rams.  My main framework for balancing design solutions and user feedback for each iteration.

Lessons and Final Thoughts 

When we started this project over 8-weeks ago, I thought the design process was to refine our initial wireframes by designing with and for people AND doing this over and over till we came up with a “good” design.  Which was part of it, but this process also allowed me to explore alternatives for design solutions.  In hindsight, this process has taught me a lot about myself and how to handle design problems moving forward, especially as we move into problem spaces not as well defined as a thermostat.
