ARERA Smart

ARERA Smart is an impartial energy service that helps people understand and reduce their energy use, with appliance-level monitoring, AI forecasts and comparisons with similar households.

Problem

90% of Italians can’t read their energy bill properly. Without understanding what they consume, people can’t tell where they waste energy or how to use less.

Solution

An impartial energy service that makes consumption understandable to everyone, regardless of their technical background. It monitors energy appliance by appliance, uses AI to predict the upcoming month, and compares each user with similar households in the same area.

Analysis of the challenge

Many people use too much energy because they don’t understand how much they’re using.

Energy services rarely explain to people what they’re consuming. We started by researching how Italians perceive their bills, and the numbers showed how widespread the problem is.

User needs

Asking “why” five times took us from the cost of energy to its real cause, and to four user needs.

01Understand how to read their bills
02Quantify their energy consumption
03Compare themselves with others
04Understand and reduce their energy consumption

Ideation

“How might we” questions broke the problem down into possible solutions.

How can wemake information about energy consumption understandable to users to help them adopt more informed and sustainable consumption habits?

How might we…

Feature

make users visualise and quantify the energy they consume?

Consumption divided by appliance, and comparison with similar users

change the experience of reading the bill?

A clear and engaging bill explanation

propose a more efficient energy model to optimise consumption?

Identifying inefficient appliances and forecasting future consumption

make users aware of how much renewable energy comes into their home?

Understand where the energy provider buys its energy from and distribute that data over the user’s consumption.

help inform users about the energy field?

AI could recommend, based on user preferences, which articles to read and on which topics to inform themselves.

Service

An impartial service that makes energy consumption understandable to everyone.

It’s designed for Italian bill holders who want to reduce their consumption and stay informed about the open market, regardless of their technical background or energy literacy.

Why ARERA

We imagined the service as part of ARERA, the Italian energy regulator, because it has no energy to sell.

Data & AI

We set the goal of each AI feature first, then the data it needed, then the algorithm. The main source is the 2G smart meter, which records consumption every 15 minutes.

Energy disaggregation

Shows what each appliance uses, from the meter’s total signal. NILM.

Clustering

Groups similar households to make the forecast more accurate. K-Means.

Forecasting

Predicts next month’s consumption, the number to beat. Deep neural network.

Interface

The first wireframes risked overloading people with data, which led to a metaphor.

The first screens organised the data but had no clear narrative. We went back to paper wireframes to simplify the information and make the visualisations clearer.

Homie

At mid-fidelity, the challenge was finding an engaging and intuitive scale for energy consumption. Homie is that scale: five statuses that show how your consumption matches the AI’s prediction.

Excellent, Good, Mediocre, Bad, Terrible.

Design system

Cards, vibrant colours and the Homie metaphor simplify the complexity of energy data and make the app feel youthful.

User test

Tests with bill holders shaped the final interface.

Bill holders of different ages and levels of digital literacy completed the main tasks while thinking aloud. Besides the changes below, the EasyBill stories now follow the Instagram format more closely, and housemates have their own section in Profile.
