Proposal text

Here's the matter we want to address together: click on each paragraph to add your votable contribution

Context

More residents are requesting EV (and plug-in hybrid) charging in the shared garage. We can either allow individual installations case-by-case, or adopt a building-level scalable system that avoids repeated works, electrical overload risk, and future disputes.

This decision affects safety (capacity, protections, fire risk), fairness (only users pay), and future-proofing (ready for more charging points). To demonstrate Concorder’s mixed-option depth, the options include attachments (guides/legal reference), pros/cons, and a separate vote on the works window using date ranges.

What we’re deciding

  • System architecture: individual-only, centralized infrastructure, or hybrid scalable
  • Non-negotiable requirements: metering, load management, safety inspections
  • Preferred works window for garage interventions

How to participate

Rank the system options, then select all mandatory requirements. Finally, select all works windows that are compatible for you (multi-select recommended). In comments: estimate how many EV users we may have in the next 12 months and note any garage constraints (cable routes, sensitive common areas).

Voting options

Vote on the different proposed options to find the best solution together.

A — Individual installs on request (with a technical rulebook)

Details

Residents install their own wallbox at their own cost, following a shared technical standard: cable routing rules, protections, max power, and metering approach, with prior notification to the building admin.

Best when

Only a few users today and we want a fast start.

B — Centralised infrastructure (dedicated panel + backbone) with user billing

Details

Install a building-level backbone: dedicated electrical panel, trunk line, protections, and activation-ready points. Energy is billed to individual users via sub-meters or a certified backend system.

Best when

We expect growth and want orderly, scalable management.

C — Hybrid scalable: minimal backbone now, progressive activations

Details

Install conduit/backbone and a minimal dedicated panel now, then add wallboxes progressively under one standard. Billing via sub-meters or backend; load management enabled from the start.

Best when

We want future-proofing without full investment upfront.
