It makes sense to start with the insulation so that the heat from the new heating system is not lost through the uninsulated walls or roof. Besides, a smaller heater will be then sufficient, which will cost less and consume less if you insulate the walls first. It is best to consult an expert from the Houzy network, who will plan and execute the renovation for you step by step.

The federal government, cantons and individual municipalities provide financial support for energy-efficient renovations. The Energy Calculator of Houzy shows all subsidies when you simulate energetic measures and their effects. On dasgebaeudeprogramm.ch you will find an overview of the subsidy measures in your canton, and on energiefranken.ch you can use the locality or zip code to query all the subsidy programs available to you.

That depends on the measures. With our energy calculator and renovation calculator, you can estimate the approximate investment costs. The energy calculator also shows how much subsidies you will receive. The investment costs are comparatively high, and the annual savings seem low at first glance. Nevertheless, an energetic renovation is worthwhile. On the one hand, because a large part of the costs would be incurred sooner or later anyway, for example for a new heating system. On the other hand, because the prices for oil and gas will increase significantly in the next few years due to rising taxes and incentive taxes.

All energy-related renovation measures make sense. Which ones are suitable for your house depends on many factors. Most heat is lost through the building envelope, which is why better thermal insulation often makes sense. But you can also save money in the long term, preserve resources and protect the environment with a new heating system or a solar power system on the roof. With our energy calculator, you can easily simulate the effects of the measures and find out which ones make sense for you. Then you can ask an expert from our network for a free quote and plan the energy renovation step by step with him.

Energy-efficient renovations are measures that reduce energy consumption, for example with better thermal insulation or new windows, or replace fossil fuels such as gas or oil with renewable energies such as self-produced solar power. Because individual measures influence each other and should therefore be coordinated, a careful planning pays off. This includes a comprehensive analysis of the current situation by experts.

The Houzy Energy Calculator takes into account the building standard and renovations, just like the GEAK® building energy certificate of the cantons. In this way, we define the actual state of a building and derive from it the renovation potential of the building envelope, the systems engineering and all electrical installations. For our analysis of the actual state, we also take into account the heating and electricity profile as well as the hot water distribution.
