Energy efficiency

Many properties lose energy unnoticed - and therefore cause higher heating costs than necessary. If you know the typical weak points, you can take targeted countermeasures and make a big difference with simple measures. Owners benefit twice over: from lower operating costs and a better indoor climate. Windows and doors: more than just passages Leaky window frames or poorly closing...

Photovoltaic systems are no longer only to be found on new buildings - more and more owners of existing properties are also relying on the power of the sun. The system becomes particularly efficient with its own electricity storage unit. This maximizes self-consumption and significantly increases independence from the electricity supplier. More self-sufficiency with battery storage Without storage, the...

With the boom in electromobility, the demand for private charging options is also growing. More and more owners want to charge their electric car conveniently and safely at home - ideally overnight, at low rates and with self-generated electricity. But what options are there and what needs to be considered during installation? Wallbox instead of household socket For regular charging, we recommend the...

With the rising temperatures in summer, protection against overheating in living spaces is becoming increasingly important. However, not every property is sufficiently equipped for this. Owners can effectively prevent this with targeted structural and technical measures and thus ensure greater living comfort - without the need for air conditioning. External sun protection is best provided by roller shutters, awnings and blinds...

Heat pumps are regarded as one of the key technologies for climate-friendly heat generation. But while they have long been standard in new buildings, the question often arises in older buildings: is it worth installing them here too? Check technical requirements For efficient use, the building should be well insulated. Without sufficient insulation, heat pumps work less effectively, as the...

Not every owner or tenant can install a conventional photovoltaic system on their roof. Nevertheless, there are attractive options for using solar power and thus making a contribution to the energy transition. Tenant electricity models, balcony power plants and investments in solar parks in particular offer alternatives for anyone who wants to be independent of their own roof. Balcony power plants -...

Summers in Germany are becoming increasingly hot. For owners and tenants, the question arises as to how living spaces can be kept pleasantly cool despite rising temperatures. With a few structural measures and clever everyday tricks, the heat can be effectively reduced and living comfort increased. Structural measures for a better indoor climate An effective measure against summer heat...

Why the energy efficiency class plays a decisive role The energy efficiency of a property is increasingly becoming a key factor when buying and selling. Buyers are paying more attention to the energy efficiency rating of a building, as this has a major impact on ongoing operating costs and the need for refurbishment. For owners, this means that a good rating increases the value of the property and...

Energy costs can be reduced and living comfort increased with intelligent heating systems. Smart thermostats and networked heating systems enable precise control of the room temperature and help homeowners save money in the long term. How does smart heating control work? Smart heating systems automatically adapt to the habits of the residents. With the help of sensors and...

Rising energy costs and the desire for greater independence from electricity providers make photovoltaic systems an attractive investment for many property owners. But when is the installation really worthwhile and what are the benefits for owners? Cost savings through own solar power A photovoltaic system enables homeowners to generate a large proportion of their own...
