One Energy-optimised building envelope is much more than just the outer shell of your house. It provides a cosy living climate without draughts and cold surfacesreduces energy consumption - and therefore heating costs - and increases the Value of your property in the long term. At the same time, homeowners are making an active contribution to climate protection by reducing CO₂ emissions.
In this article, we show the many advantages of a well-insulated building envelope and explain why an investment pays off, especially in Switzerland, thanks to subsidy programmes and stricter energy regulations.
More comfort and a better indoor climate
A refurbished building envelope noticeably increases living comfort. High-quality insulation and tight windows ensure stable indoor temperatures and prevent draughts and cold walls. In summer, good insulation also protects against overheating.
In addition, less noise penetrates from outside, which improves the peace and quiet in your home. All these factors ensure greater cosiness and a pleasant indoor climate.
Save energy and reduce heating costs
Heating accounts for the largest share of energy consumption in residential buildings - the savings potential is correspondingly high. In unrenovated old buildings, over 80 % of heating energy can be lost due to an inadequate building envelope. Modernisation can reduce energy requirements by up to two thirds.
The result: significantly lower heating costs and greater independence from energy price fluctuations. A house with low heating requirements is also better equipped to cope with rising prices.
Increasing and maintaining the value of your property
Energy-efficient refurbishment not only increases living comfort, but also the market value of your property. Improved energy efficiency and greater comfort make your home more attractive and ensure sustainable value retention.
Improved energy efficiency and greater comfort increase the market value of your property and ensure that it retains its value in the long term - while also reducing the risk of structural damage caused by cold or damp. In addition, the property moves into a better energy efficiency class (e.g. in the GEAK energy performance certificate), which makes it significantly more attractive to potential buyers and means you can expect a higher resale price.
Active contribution to climate protection
In Switzerland, buildings are responsible for around a third of CO₂ emissions. Every kilowatt hour of heating energy saved reduces CO₂ emissions. Better insulation can reduce the heating requirements of an old building by more than half.
This is how you can actively contribute to the climate targets: The building sector should be CO₂-free by 2050 - this can only be achieved with more efficient building envelopes.
Funding programmes and legal framework conditions
Strict energy regulations apply to new buildings in Switzerland. For existing buildings, there are attractive subsidy programmes that provide financial support for renovations. Owners can apply for subsidies for insulation measures or the replacement of heating systems - it is important that the application is approved before construction begins.
In addition, the costs of an energy-efficient renovation can be deducted from taxable income, which makes the investment even more attractive.
Future-proof: keeping an eye on energy costs and standards
An energy-efficient refurbishment of your building envelope is also an investment in the future security of your property. Heating energy prices can fluctuate greatly - the less energy your home requires, the more relaxed you can react to price increases.
In addition, energy standards are constantly being tightened. With a well-insulated façade and an efficient roof, you are one step ahead of the upcoming regulations. Experts predict that a building with high-quality insulation will still fulfil the legal requirements in 10 or 20 years' time - this can save on expensive retrofitting in a few years' time.
Conclusion: More convenience, lower costs, more future
A well-insulated building envelope pays off in many ways: It increases comfort, reduces energy costs and secures the value of your property in the long term. You also make an active contribution to climate protection and make your home fit for the future.
