Overview
Why this canton page matters
In Valais, a clear local reading prevents general renovation aid from being confused with heating-specific cases. This page works as a local hub to place the right programmes, the right authority and the right timing before discussing a measure or a file.
Which local logic comes first?
The first question is not only "which subsidy exists?" but also "which project are we really talking about?". A heating replacement, an envelope renovation or a link with a federal programme do not belong to the same reading layer or the same timing.
How should canton, programme and project be connected?
The canton sets the local logic and the correct starting point. A heating project should then connect to the relevant heating project page, to the Building Programme for the cantonal layer and to the Impulse Programme when temporary federal support enters the picture.
Which entry point should be used on maprime.ch?
Use this page to qualify the Valais local framework. As soon as the question becomes technical, documentary or comparative, move to the programme or project page closest to the real case.
