PowerPal

THE PROBLEM: Energy bills continue to rise, yet many renters and homeowners and renters don’t understand what is driving the increase. Most energy monitoring tools show raw data without context, leaving users to guess instead of make informed decisions.
THE SOLUTION:
DESIGN SPRINT 1

User Flow
I began by identifying the core user needs:
Reduce energy bills
Understand cost drivers
Lower carbon footprint
Competitor Research
I analyzed existing energy monitoring platforms, including Loop, to understand how they:
Present consumption data
Motivate continued engagement
Reinforce habit-building
This helped identify gaps in clarity, personalization, and behavioral motivation.
User Journey Mapping
I mapped the typical energy experience:
Bill arrives
User reacts to high cost
Attempts temporary reduction
Forgets to continue new energy saving habits until next bill arrives
DESIGN SPRINT 2

Site Architecture
I structured the app around:
Dashboard
Graphs
Devices
Energy Education
Energy Management (Goals)


Low-Fidelity Wireframes
Focused on:
Clear hierarchy
Multiple data visualizations (bar, line, bubble)
Device breakdown
Goal-setting feature

Testing & Affinity Mapping
I conducted user tests with:
4 participants
Renters (20s)
Homeowners (30s)
~10-minute sessions over Zoom
Key Findings
50% of users struggled to find “Energy Consumed Today” outside the dashboard.
50% showed little interest in energy education and preferred specific usage details instead.
Users preferred bar charts for quick comparisons rather than lines.
A correlation emerged between interest in Goal Tracking and higher frequent app use.
Three users recommended friendlier, more vibrant colors.
Affinity mapping helped cluster issues around:
Discoverability
Label clarity
Visualization hierarchy
Motivation
DESIGN SPRINT 3
New Changes

Added “View More” buttons for clearer navigation pathways
Made the Bar Chart the first visible visualization
Displayed Goals first on the Energy Management page
Renamed:
“Device List” → “My Devices”
“Set Up Device” → “Add Device”
and “Graphs” → “Graphs & Usage” for simpler, and friendlier language
Created a toggle button Line/Bar chart on the Dashboard
Updated “Energy Consumed Today” to include breakdown by device
Reduced emphasis on Energy Education (still accessible but secondary)
Testing (Sprint 3)
Testing the revised wireframes revealed a larger behavioral insight:
Users may not need extensive energy education because they primarily check the app near their billing cycle.
This raised a new challenge:
How can we keep users engaged throughout the month?
This led to the introduction of gamification.
DESIGN SPRINT 4
Introducing Gamification: PowerPal
To increase engagement frequency, I introduced PowerPal, a gamified feature that transforms energy-saving into a rewarding experience.
Concept
A PowerPal turns energy saving into a rewarding journey. By completing personal goals or daily challenges, users earn Eco Points. With Eco Points, they can grow a virtual garden, forest, or energy-efficient city, while saving money and reducing their environmental impact in real life.
Core Mechanic
Goals became the primary way to earn points
Daily challenges encouraged consistent check-ins
Visual growth reinforced positive behavior

Testing PowerPal
To test users and better know what the goal function could include, users were asked:
What do you think PowerPal is for?
How would you view your current goal?
How would you set a new goal?
How would you customize your PowerPal world?
What energy-saving goals would you set?
Findings
Users clearly understood that PowerPal was tied to progress
Goals were the strongest motivator
The virtual growth system increased emotional investment
Gamification successfully addressed the low mid-month engagement issue.
DESIGN SPRINT 5
In the final sprint, I tested the high fidelity prototype.
Users were asked to:
Check live energy consumption
Identify appliances currently in use
Check energy usage by room
Add a device
View and edit goals
Access PowerPal
Results
Navigation labels were significantly clearer
Live consumption was easier to locate
Goal creation was intuitive
PowerPal added perceived motivation
Visual hierarchy improved data readability
Final Outcome

Sign In & Dashboard

Graphs

Devices

PowerPal & Goal Setting
The redesigned energy monitor transforms passive bill-checking into an engaging, goal-driven system.
Instead of reacting once a month, users are encouraged to:
Track daily usage
Identify cost drivers
Set meaningful goals
Earn rewards
Build long-term energy-saving habits
By combining smart data visualization with behavioral motivation, the app empowers users to reduce costs and their carbon footprint consistently, not just at the end of the month.
