Intelligent building control using smart data technology

Deka Immobilien is relying on smart data technology to improve energy efficiency and promote decarbonisation. An intelligent building control system uses a digital twin to manage building operations optimally.

We use intelligent, scalable solutions in order to significantly reduce our portfolio’s energy consumption and CO2 emissions in the long term. MeteoViva is one of the partners helping Deka Immobilien achieve our ambitious sustainability goals.

Optimised indoor climate, lower operating expenses

Many buildings consume energy unnecessarily by allowing technical systems such as heating, cooling and ventilation to run even though the user does not need them at the time. Higher operating costs for the building and a worse carbon footprint are the result.

Digitalisation and connectivity measures make it possible to reduce a building’s ecological footprint compared to the average. This is where the smart data technology MeteoViva Climate developed by MeteoViva comes in. The tech company from Jülich, Germany, has developed building control software that amalgamates relevant operating data (such as energy and service prices, building physics and technology, as well as weather forecasts) in a dynamic digital building model and analyses it to proactively optimise the management of building services equipment.

Future environmental conditions and utilisation parameters are anticipated and used as a basis for calculating the most favourable settings for the building’s systems in order to achieve the desired indoor climate. The simulation model determines the ideal operating parameters for the systems and then intervenes directly to help control them. As a result, just the right amount of heating, cooling and fresh air flow into the building interior at the proper time to create the desired indoor climate.

MeteoViva Climate smart data technology gives buildings the right “intelligence”:

Smart data solution for greater well-being and energy efficiency

This technology provides a variety of benefits for anyone who uses a building.

  • Lower operating costs by adapting energy consumption to users’ needs

  • Reduced CO2 emissions throughout the building

  • Optimised indoor climate conditions and fewer employee complaints

The use of innovative smart data technology can save between 15% and 45% of indoor climate-related energy costs on average. We are initially aiming for this digital solution to help 100 Deka Immobilien portfolio properties achieve a real reduction in CO2 emissions of up to 15,000 tonnes per year.

Forward-looking examples of a sustainably optimised indoor climate that reduces energy consumption

The two Hamburg office and commercial buildings “Fleethof” and “Hohe Bleichen 7” are among the first fund properties to be equipped with MeteoViva’s smart data technology. Initially launched in Germany, the partnership was extended to include buildings in other European countries and the US in 2021.

Data-based building management gains importance in certification

For the real estate industry, planning, building and managing buildings sustainably is the order of the day. That is why certifications for sustainable buildings – such as DGNB, BREEAM or LEED – play an ever more important role. They enable a structured approach to rating buildings based on social, ecological and economic criteria while also acting as an external indicator of a building’s sustainability.
