Renovation to create an ecological apartment building
Apartment house modernisation
The thermal insulation must be replaced and brought up to modern standards throughout the entire building. This includes replacing all windows and exterior doors. But well-insulated buildings have an insufficient supply of fresh air, which increases the risk of mould formation.
Therefore, it is sensible to install ventilation ducts as well. All in all, the cost and the amount of work required are high.
Reasons for choosing this heating system
After talking to their construction advisors and energy consultants, the house owner decides to replace the old gas heating system with a modern heat pump. They also plan to use a modern ventilation system on every floor to prevent mould from forming and protect the substance of the building.
These two systems have been tried and tested in practice and continually improved for many years. They will still be state of the art for many years to come.
Heat pump systems use energy from their surroundings. They do not need any fossil fuels or produce exhaust gases that are harmful to the climate. The electricity required to run them is converted into heat with great efficiency. The owners can generate this electricity using an on-site photovoltaic system installed on the roof. This improves the ecological footprint of the system still further.
Modern appliances feature practical automatic functions. More and more manufacturers are starting to equip their systems with smart home interfaces and provide apps for controlling the systems from a smartphone. These allow the owners to monitor and adjust the appliances even when they are not at home.
Economically sensible investment
The investor can claim high subsidies for the entire renovation. This saves a large part of the investment costs.
The remaining investment costs pay off in the long term. This is because the heating demand of the building is reduced to such an extent that it can be completely covered by the heat pump heating system. The owner of the house makes himself independent of the costs of fossil fuels, which have been high up to now and will continue to rise in the future. The running costs are very low. The heat recovery of the ventilation system saves additional energy.
All this reduces the service charges to be passed on to the tenants and makes the flats even more attractive. In addition, the owner creates more security for himself. Because with this particularly sustainable heating system, he also fulfils the legal requirements in the long term, which may be extended in terms of climate protection.

Renovating older buildings is worthwhile
By optimising the building envelope of the old apartment block and coordinating the systems precisely, the owners can run the heating system exclusively using renewable energy. This also makes the project eligible for attractive subsidies and will be extremely convenient for future tenants when it comes to heating their apartments. Furthermore, the building will continue to fulfil efficiency requirements in coming years.
