Increased value and energy efficiency for your building

About PAUL

We enable CO₂ neutrality in buildings to keep our planet livable.

PAUL stands for

  • Digitalization,
  • Artificial intelligence, and
  • Innovative solutions for energy-efficient buildings.


Beyond these, our expertise extends to the technical side of real estate management. We balance our roles as innovators and developers with practical experience. PAUL emerged from a sanitary company already focused on automating drinking water systems at the end of the 1990s.

The energy-saving potential identified there led to the formation of PAUL in 2017. As a tech company, we’re dedicated to solving one of the most significant challenges of our time: reducing the high energy consumption and harmful CO₂ emissions of buildings while maintaining profitability.

Our vision

We aim to transforming the real estate market to achieve carbon neutrality well before 2045.

Our mission

As an energy innovator, we create cutting-edge technologies and solutions to reduce CO₂ emissions from properties while enhancing their value.

We are proud of this

Our commitment to our customers

We serve a broad range of clients, including real estate investors, private and municipal housing associations, and companies with real estate portfolios, although that is not their core business.

Our solutions are effective for buildings with 20 residential units and scale up to portfolios with tens of thousands of residential units. They are versatile across all asset classes, including care properties, hotels, offices, residential, retail and even maritime applications like ships.

PAUL enhances the eco-friendliness of our client’s buildings and increases their value by improving their energy efficiency classes.
