CERLES

The getting-started experience for Siena's first renewable energy community

Period
2022 — BSc thesis
Context
BSc thesis with Comitato Siena 2, promoter of the Siena Nord renewable energy community (CER)
Role
Sole UX designer across the full cycle — research, strategy, UX and UI up to the hi-fi prototype
Programme
BSc thesis — Communication Sciences, University of Siena
6

16

Problem

The energy transition asks citizens to become active players — prosumers — but the road into a renewable energy community (CER) is paved with fragmented, contradictory, overly technical information and a legislative process in constant motion. Interest is growing; understanding isn't.

Target user

Carmine

51

Profile
Pragmatic; wants to verify the primary substation and the current legislative status before moving.
Goal
Understand whether his home can technically join the community.

Laura

38

Profile
Focused on the economics: discovering the incentives and monitoring how they are split.
Goal
Know exactly what joining is worth on the bill.

Rosa

32

Profile
Environmentalist, social-media savvy; wants clarity on panel disposal and environmental benefits.
Goal
Contribute to the planet without greenwashing doubts.

Giuseppe

70 — retired

Profile
Low digital literacy, helped by wife and daughter; prefers traditional and phone contact.
Goal
Understand whether he can participate without solar panels.

My role

As the sole UX designer I owned the entire design cycle, acting as the bridge between Comitato Siena 2 — the community's promoting body — and the local citizens: research and strategy (interviews, benchmark, competitor analysis), UX (information architecture, personas, journeys), and UI (iterative mock-ups up to the hi-fi version).

Process

  1. 01

    Empathize

    FAQ analysis (Enel, ènostra, GSE…), heuristic benchmark of communities like Grupo Creluz (Brazil) and Brooklyn Microgrid, and 16 contextual interviews.

  2. 02

    Define

    4 research-based personas, 8 user journeys exposing pain points like the POD code and the GSE site, and How-Might-We questions.

  3. 03

    Ideate

    Two storyboard iterations to place the energy community inside citizens' daily lives, and a progressive-disclosure information strategy.

  4. 04

    Prototype

    6 iterations driven by weekly feedback with the client, from the information architecture to the hi-fi prototype.

User journey — Giuseppe, 70: joining without panels
  1. 01 · Trigger

    Actions
    Giuseppe hears about CERs on TV and looks them up on the internet.
    Pain point
    The search returns a confusing mass of different pages and sources.
    Opportunity
    A very simple guide gathering all the key information.
  2. 02 · Phase 1

    Actions
    After reading a few sites, it's still unclear whether he can join without solar panels.
    Pain point
    Information that should be immediately clear to everyone isn't.
    Opportunity
    Spell out the community roles directly on the home page.
  3. 03 · Phase 2

    Actions
    He asks his daughter to check online for him, but even she can't figure it out.
    Pain point
    The answer is hard to find or given as obvious — it can make interested users give up.
    Opportunity
    Write out even what seems obvious.
  4. 04 · Phase 3

    Actions
    He wants to talk to a person: he calls the number in the site's contact section.
    Pain point
    He'd have preferred to find the answer on the site itself.
    Opportunity
    The FAQ section must contain these answers.
  5. 05 · Goal

    Actions
    He completes his membership in the CER as a consumer.
    Opportunity
    Give the FAQ a highlighted position on the site.

Key decisions

  • Progressive disclosure: bureaucratic depth is revealed gradually so first contact never overwhelms.
  • A podcast-style audio explaining the basics — an access route for users who won't read normative text.
  • A searchable FAQ in a highlighted position, answering even the “obvious” questions the interviews proved weren't obvious.
  • An expression-of-interest form where the POD code is optional — it speeds up paperwork without blocking whoever can't find it.

Final result

The sixth iteration is a hi-fi prototype built on Wix: an impact home stating the energy transition plainly, benefits split into economic, environmental, and social, searchable FAQs, a news section tracking the legislation — the trust builder — and the simplified expression-of-interest form.

What I learned

  • Design for trust: in projects with real economic and social stakes, clarity beats aesthetics, and transparency about the law is what reassures most.
  • Weekly iteration with the client was vital to keep the prototype aligned with the community's real needs.
  • Turning technical terms (POD, primary substation) into concepts people can absorb is the designer's real mission in this sector.
