How to significantly reduce energy demand and CO2 emissions

Switzerland has set itself the goal of emitting no more greenhouse gases by 2050 - at least on balance. You know this ambition under the term "net zero target". However, this can only be achieved if private individuals also reduce or offset their emissions. And this is where homeowners are particularly challenged.

Inform now and act soon enough

Cantons and municipalities are already rolling out corresponding measures. For example, there are neighbourhoods where fossil-fuel heating systems are banned in the medium term and must therefore be replaced. Such regulations are a trend that will certainly increase - because the pressure from politics will continue to rise. Be sure to deal with the topic of energy refurbishment so that there are no surprises. Here we have summarised the most important points for the right approach:

Step 1: Know the property

Do you know your property well enough to be able to assess where the energy improvement potential lies? If not, you should definitely tackle it: It's a bit like knowing your own state of health. An important basis for decision-making, isn't it? With Liiva, for example, you have the opportunity to create a kind of digital twin of your house free of charge. With just a few clicks and in a completely self-explanatory way, you enter the key data of the components of your property. Based on this key data, our modernisation assistant calculates the annual CO2 emissions and energy costs as well as your energy consumption and energy efficiency. In this way, you know where you stand and quickly recognise where there is a need for action. Based on these values, you can see whether it is worth pursuing the topic further.

Step 2: Know the possibilities

Now you should find out what the concrete measures could be to improve the condition and future viability of your property. Liiva also offers this free of charge - and quite cleverly, because it is holistic. With Liiva you find out:

• which concrete measures you can take to reduce CO2 emissions and energy costs or increase your energy efficiency.

• when best to invest in which measures, with a focus on value enhancement

• which measures are interdependent, and how

• what investment costs can be expected in the process

The advantage of such a holistic view is obvious: your property is assessed comprehensively and not reduced to individual components. Individual measures will also have an influence. But you will achieve by far the best effects if you renovate your property holistically and with the corresponding interdependencies.
With Liiva it is also possible to try out different scenarios and compare them with each other: What happens if I only renew the heating but not the façade? When does what make sense - and in what order? You should also consider whether you want to tackle energy renovations together with visual or other value-enhancing renovations. This decision mostly concerns old buildings.

Step 3: Secure funding

Have you made a plan for your measures? Then the next thing to do is to look into financing. Part of this should be clarifying possible subsidies. This way you can increase the profitability of your investments even more. There are now many subsidy options: for example, federal programmes in the area of heating or photovoltaics, or numerous cantonal programmes. The federal government and the cantons offer a helpful overview with the so-called "Building Programme".

There are various financing options. Basically, it is necessary to distinguish between loans and mortgages - and in some cases also to convert them. The best solution is individual and depends above all on the current condition of the property. For planned more comprehensive renovations, however, mortgage top-ups or renovation mortgages are usually discussed. Liiva also provides support here: Our platform offers a mortgage comparison for renovations and refurbishments.

Now it's up to you: Will you take your renovation project in hand?
