How to proceed

An energy renovation typically consists of several mutually supportive measures. Smaller building technology adjustments combined with larger measures, such as geothermal heating or heat recovery, often produce good results. Combining energy renovations with other major renovations, such as plumbing, is often a cost-effective option.

These are the steps for an energy renovation

  1. 1
    How to get started

    As your first step, discuss the possibility of an energy renovation with the board of the housing company. Options for getting started include contacting the energy advice service, requesting quotes from industry operators, or approaching consultants to commission an energy efficiency survey. The experts at the energy advice service for housing companies will help and guide your housing company in the right direction, considering your initial situation.

  2. 2
    Authorisation from the general meeting

    Discuss the energy renovation at your general meeting and obtain its authorisation to investigate further and potentially commission an energy efficiency survey. The cost of an energy efficiency survey for a housing company is usually a few thousand euros, which is a fraction of the total investment in an energy renovation. Measures with smaller impacts, such as the purchase of a solar power system, require less surveying than larger ones.

  3. 3
    Commissioning an energy efficiency survey if necessary

    Commission an energy efficiency survey and identify the best energy efficiency measures. The content of an audit can vary a lot depending on your initial situation and the needs of your housing company. The audit can compare different heating methods and combinations of various measures. However, not all energy renovations will require a separate energy efficiency survey. Use the energy advice service to assess your audit needs and prepare your call for tenders.

  4. 4
    Planning

    Use the results from your energy efficiency survey to make a plan to improve the energy efficiency of your building. Use the results of the energy efficiency survey, the tenders you receive and the assistance you get from the energy advice service to make a plan to improve the energy efficiency of your building. Consider other renovation needs and how you can combine them with the energy renovation.

  5. 5
    Competitive tendering and implementation

    Invest in the most cost-effective measures and use a professional to plan and manage your renovation. Use the energy advice service to help you evaluate the tenders.

The city’s energy experts support housing companies in the process, but the housing companies are responsible for the actual contracting, implementation, and payment for renovations.
