Check your energy efficiency

Anyone who is interested in improving the energy efficiency of their home should consider a GEAK or a GEAK-Plus audit. A GEAK audit gives you, as property owner, an objective assessment of the energetic state and efficiency of your building. The report helps you better determine what steps and measures you could take to improve your home by, for example, changing heating from oil or gas to a much more efficient heat pump system, update your insulation, update your water heating system, and many other valuable recommendations. Most cantons also offer subsidies to cover much of the costs for a GEAK.

Save money

Changing to a heat pump or updating the insulation involves a certain investment. It is important to understand how such an investment will save you money in the short to medium term. This is why the GEAK report also contains a part relating to profitability. The GEAK is also recognized by various financial institutions, which leads to favorable terms for mortgages. And through the GEAK, the value retention of a building becomes clear and various renovation options are comparable. In addition, topics such as investment optimization and funding measures are addressed in the GEAK advisory report, which gives house owners, or potential buyers and sellers, an excellent overview of this topic.

Necessary for heat pump subsidies

If you have already decided to install a new heat pump or to do some other substantial energy improvement to your home, a GEAK report is still essential. It does not only help you in determining which heat pump is the best fit for you, but it is also needed in order to get the cantonal subsidies, which could be up to 25'000 CHF.

Benefits in a Nutshell:

  • Necessary for heat pump subsidies
  • Helps house owners understand how to make their home more energy efficient
  • Helps house buyers and renters understand energy needs and costs
  • Valid for 10 years
  • The official standard in Switzerland, which means transparency and comparability
