Honeywell
Innovative App Design for a Global Tech Leader



Project description:
Smart Design Makes Energy Visible
With over 120,000 employees and operations in 95 countries, Honeywell is among the world’s leading technology companies. With the new Heat Load Calculator, Honeywell brings this expertise directly into the hands of professionals and end customers. Fully compliant with DIN EN 12831, the app combines precise engineering with intuitive design. It allows users to quickly and transparently analyze rooms and identify where valuable energy is being lost.
When planning heating and cooling systems for new builds or modernizations, determining the heat demand is a critical step. In existing buildings, however, this process is often complex and difficult to assess. This is exactly where the app delivers: it translates intricate calculations into an intuitive user journey that requires no expert knowledge. Step by step, data is captured, visualized, and transformed into clear, actionable results.
The interface makes the process transparent and reduces complexity to its essentials. Clean typography ensures readability and a clear information structure, significantly enhancing user perception and interaction.
As a digital tool, the app supports professionals in customer conversations by instantly visualizing results and highlighting potential savings. At the same time, it serves as a powerful brand touchpoint: every interaction with the Heat Load Calculator reinforces trust in Honeywell – through clarity, precision, and a user experience that makes the brand’s values tangible.
