Buildings worldwide consume around 40 percent of global primary energy. Energy costs are one of the biggest cost factors for operating expenses. The greenhouse gases released due to the energy consumed also make a major contribution to climate change.
We work continuously to reduce the energy consumption and CO2 emissions of our portfolio properties, while simultaneously improving the customer experience for tenants in our buildings.
For many years, Deka Immobilien has preferred investing in "green buildings" — buildings developed with a main focus on sustainability and that satisfy high environmental, technical and socio-cultural (well-being) standards. Deka Immobilien has a certification rate of around 70 percent, based on the total value of its real estate portfolio, making its real estate holdings among the biggest in Germany.
We are working with the technology company MeteoViva on another important measure for achieving our goals by implementing potential optimisations during regular operation. The patented MeteoViva Climate smart data solution provides buildings with the right "intelligence" to maintain a constantly comfortable indoor climate while significantly reducing energy use.
Unlike conventional building control systems, MeteoViva Climate does not simply react to building conditions and external temperatures — instead, it anticipates future environmental conditions and usage parameters and proactively adjusts the building services. As a result, just the right amount of heating, cooling and fresh air flow into the building interior at the proper time to create a comfortable climate.
Use of the innovative smart data solution reduces energy costs by an average of 15 to 45 percent. We are using this digital solution for 100 properties in the Deka Immobilien portfolio, with the aim of reducing CO2 emissions by up to 15,000 tonnes a year. In comparison, a beech tree needs to grow for 80 years to compensate for one tonne of CO2 emissions.
