Pilabz Heat Pump Dashboard

A real-time embedded dashboard designed for a campus heat pump installation, making technical performance data understandable at a glance for both engineers and non-technical employees.

01 — Problem

Dense engineering data. 3 seconds to read it.

The dashboard had to show six live metrics — COP, electrical power, heat delivered, cumulative savings, and daily averages — on one fixed screen. There was no interaction, scrolling, or second-level detail.
The challenge was to make dense engineering data readable from a distance and meaningful within a few seconds.

02 — Design decisions

Three choices that defined the screen

Led with system value, not system data

The dashboard leads with COP and cumulative savings because they answer the user’s first question: “Is the system performing well, and is it creating measurable value?”

Instead of starting with raw sensor readings, the screen begins with the metrics that turn system behaviour into a clear performance story.

Rejected

A sensor-first dashboard that showed all engineering values upfront and left users to interpret the outcome themselves.

Used a visual anchor for performance understanding

COP is not shown as a number alone. The gauge gives the value context by showing its position within a performance range.

The large 5.5 Instantaneous COP supports precision, while the gauge helps users understand direction and performance quality at a glance.

Rejected

A simple numeric COP card that was accurate, but lacked range, context, and quick interpretability.

Made business impact impossible to miss

Cumulative savings is treated as a primary metric because it translates technical efficiency into a business outcome.

This made the dashboard useful beyond engineering users. A facility manager, business owner, or stakeholder could immediately understand what the system was contributing without needing to decode technical readings.

Rejected

Placing savings below engineering values, which would make the system’s business impact feel secondary.

04 — Reflection

What this project taught me

This project taught me that UX is not always about interaction. In an ambient display, the main job is clarity. The screen has to communicate without asking the viewer to stop, tap, or explore.
