Energy certificate
The cantonal certificate: an assessment of the envelope and the building services, expressed in two classes.
ViewFirst establish where the building stands. Then decide in what order to invest — and only then, what support exists for it.

ViewA construction standard with a calculation behind it, not just a label: evidence, certification and inspection to handover.
ViewReplacing oil or gas: feasibility, flow temperature, envelope work required, running costs.
ViewThe common mistake is to replace the plant before looking at the envelope. A heat pump in an uninsulated building needs high flow temperatures, performs poorly and costs more to run than expected. Conversely, insulating without adjusting the controls gives back part of the gain.
So every energy study we do starts with a survey and a calculation, and ends with an order of works rather than a product recommendation.
It depends on the canton, the triggering event and the building category — the rules are not the same everywhere. Describe the situation and we will check what applies in your case.
As a rule yes. An application submitted after the work has begun is usually refused. The sequence is part of the planning.
Often, but the answer depends on self-consumption, not on roof area. We calculate the profile before recommending anything.
Tell us the building and the stage it is at. You will get an assessment and a fixed fee per phase, with no obligation.
