National and EU energy programmes, including the panel renovation subprogramme and related home renovation calls, typically open annually in defined months and accept submissions until the budget runs out or a fixed deadline. Exact timing changes yearly, so always follow the official call of the given year.
District and city programmes follow a different logic: they usually align with the local budget cycle and appear in spring or early summer, after the annual budget has been adopted.
Bank green loan products, by contrast, are continuously available with no narrow submission window, so they can be treated as flexible supplementary funding for own contribution.
An effective practice is for the supervisory committee to keep a simple annual grant calendar recording when each programme usually opens, and to prepare the base documents in advance: energy certificate, meeting authorisation for a project type, own contribution plan.
It is also worth considering that implementation of a project often has to be completed within a given calendar year or before the next heating season under the funding contract, so the implementation deadline belongs in the plan too.
Merbo keeps a grant calendar tailored to each managed building's profile, containing not just submission deadlines but also the preparation steps, so no relevant opportunity goes unused.
This kind of forward planning matters especially in a year when several sources open at once and priorities must be set.
