Deka Immobilien: Focusing on sustainability

A commitment to sustainability lies at the very heart the Deka Group business strategy. Deka Immobilien has taken the basic principles of its parent company's approach to sustainable corporate governance and used them to create its own sustainability strategy to ensure that the issue is treated with the appropriate significance.

Central elements and key points of our operating activities:

Achieving an overall reduction in CO2 emissions
Including more green contract clauses in property, facility and lease agreements
Reducing operating expenses using sustainable management and energy-related renovations
Integrating environmental and social concerns and good corporate governance into processes related to real estate and fund management

UN Global Compact and German Sustainability Code

Deka Immobilien formally recognised the UN Global Compact and German Sustainability Code in 2015.
The United Nations Global Compact is the furthest reaching and most important initiative for responsible corporate governance in the world. Based on 10 universal principles relating to human rights, labour standards, environmental protection and the prevention of corruption, it promotes a vision of an inclusive and sustainable global economy that benefits all people, communities and markets both today and in the future.
The German Sustainability Code was prepared by the German Council for Sustainable Development after extensive dialogue with representatives from corporate groups, medium-sized companies, financial analysts and financial service providers. Its aim is to develop a declaration on the environmental, social and economic aspects of sustainability—including criteria for sustainable corporate governance—that can be easily implemented and applied to the key elements of the business model of a company.
Deka Immobilien also regularly takes part in meetings held by the "EU and international" committees and the "Responsible investment" and "Sustainability in real estate funds" working groups of BVI as well as the "Corporate Social Responsibility" committee and the "Climate protection plan 2050/Inventory" working group of ZIA in order to obtain and exchange information about the latest political and legal developments. Deka Immobilien is also a member of the Institut für Corporate Governance (ICG), which engages in the further development of sustainable governance structures in real estate companies.

Sustainability filter

Sustainability filter for universal investment fund liquidity

Since 2018, a sustainability filter has been in use for mutual and specialised investment fund liquidity. This filter is based on the ten principles of the UN Global Compact and excludes a variety of controversial areas of business. Approximately EUR 6.2 billion has been managed using the filter as of 31/12/2019.

Every transaction is checked by the EIRES database (Ethical Investment Research Service) for violations of the following criteria:

  • Environment & biodiversity
    Failure to adequately address serious environmental scandals
  • Chemicals that destroy the ozone layer
    Production and sale of chemicals that destroy the ozone layer without an exit strategy
  • Controversial weapons/armaments
    Production of controversial weapons or relevant system components, and/or offering related services
    (cluster bombs, anti-personnel mines)
  • Human rights & employment rights
    Failure to appropriately address violations of international human rights conventions or key ILO labour standards (child labour, forced labour, discrimination, freedom of assembly)
  • Money laundering
    Failure to appropriately address cases of money laundering
  • Corruption
    Failure to appropriately address cases of corruption and bribery

Energy and CO2


Deka Immobilien focuses on renewable energy

Since 2013, we have been helping to mitigate the effects of climate change by sourcing certified green energy. Building operations such as lighting and air conditioning require high amounts of energy and therefore present an excellent opportunity for reducing CO2 emissions. "Grey energy" is a term that can be used to refer to energy generated from conventional sources, i.e. a mixture of nuclear energy, fossil fuels (such as mineral oil, coal and natural gas) and renewable energy sources (such as wind and solar energy).
Converting the communal spaces and technology at the majority of the German properties in the Deka Immobilien portfolio from grey energy to 100% green energy could save up to 30,000 tonnes of carbon dioxide per year. We also switched to green gas on 01/01/20, which will further offset approximately 9500 tonnes of CO2 emissions per year.


Smart data solutions for enhanced wellbeing and energy efficiency

As a responsible investor, we pay great attention to the issue of energy efficiency in our buildings, as well as the wellbeing of our tenants. To that end, we began an exclusive partnership with the technology company MeteoViva in 2019.
By 2022, at least 100 of our buildings worldwide will be equipped with the MeteoViva Climate smart data solution as a means of actively controlling and monitoring building operations using smart data. (As of Q1 2020: installed and operating in 10 properties). 
Using MeteoViva technology in Deka properties will have a significant impact on sustainability by reducing CO2 emissions, while also improving the quality of life for building tenants and increasing the intrinsic value of our real estate portfolio.

Our initial experiences indicate that this technology has led to a reduction in climate-related tenant complaints, and we are also expecting to reduce CO2 emissions by an average of 20%.

MeteoViva Climate

The MeteoViva Climate smart data solution provides buildings with the right "intelligence".

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 calculates the best settings for technical building services to achieve the required indoor climate.
As a result, just the right amount of heating, cooling and fresh air flow into the building interior at the proper time to produce the required indoor climate.

The MeteoViva Climate records all relevant factors affecting indoor climate so that the existing technical building services can be controlled proactively. These include energy prices, demand rates, building physics, technical building services, information on usage and local weather data for the next three days.

„Green Building“

Deka applies its social responsibility to several divisions within the company.

In 2019, Deka Immobilien awarded a Deutschlandstipendium [German scholarship] for the first time, within the scope of long-term cooperation with different universities.

The scholarship is supporting a Bachelor's student in the "Green Building — Building technology, energy efficiency, people and the environment" study programme at University of Applied Sciences and Arts in Lower Saxony (HAWK). 

By awarding this scholarship, Deka Immobilien is supporting a scientific approach to the issues of sustainable construction and digital planning.


Sustainable portfolio revaluations

Going forward, one of the major issues for the real estate industry will be the conservation of resources.
As a long-term property investor, we oversee properties throughout their entire
life cycle. At certain points in this cycle, every building requires some sort of modernisation in order to stay marketable. Portfolio revaluations ensure that value is retained, which in turn benefits the environment as well as our tenants and investors.
In 2019, Deka Immobilien extensively modernised and completely refurbished 8 buildings with a total volume of EUR 180 million, all while taking compliance with sustainability criteria into account. We are helping to conserve resources by actively improving the energy efficiency of our buildings.

You can find a selection of our portfolio upgrades here.


Sustainability Certificates

Certification of a large number of our fund properties is an important part of our commitment to sustainability. This focus on sustainability in the building sector is based on a comprehensive approach to the property life cycle using environmentally-friendly technologies, while ensuring profitability at all times. Property sustainability certificates allow compliance with sustainability criteria to be measured and compared based on nationally established and internationally recognised certification systems. These include, for example, the Building Research Establishment Environmental Assessment Method (BREEAM*), Leadership in Energy and Environmental Design (LEED®) and the German Sustainable Building Council (DGNB).

Certification systems - Similarities and differences

The core purpose of these certification systems is to rate the environmental, social and functional quality of buildings. The German DGNB rating is the one that reflects the "complete" definition of sustainability: ecology | economy | sociocultural issues. BREEAM and LEED mainly focus on the environmental aspects.


Sustainable Portfolio

We focus on sustainability and our high quality portfolio boasts 258 certified sustainable properties at the end of 2019, including, for example “The Edge” in Amsterdam, “Kings Place” in London, “Tower 185” in Frankfurt, “Silvers” in Dusseldorf or “DC Tower 1” in Vienna. As at the end of 2019, certified buildings represented 68 per cent or EUR 26.7 billion of our global real estate assets under management. Thus, our »Certification Ratio« has more than doubled in the past five years.

Selection of certified buildings

“The Edge” in Amsterdam sets new sustainability standards

Deka Immobilien’s “The Edge” property in the Zuidas district of Amsterdam is one of the most innovative buildings in the world. “The Edge” received BREEAM New Construction sustainability certification with a rating of “Outstanding”, and in December 2014 achieved the highest score received so far for a sustainable office building anywhere in the world. In 2016, “The Edge” office building won the BREEAM Award in the "Office New Construction" category.


“Kings Place” in London wins 2017 BREEAM Award


The building itself is already unusual. Located directly on the Regent Canal in London, the property includes office space as well as a restaurant, art and event areas and a theatre. Building management received an “Outstanding” rating under the BREEAM In-Use rating system, achieving the highest score ever granted in the United Kingdom. The building implements a well-thought-out sustainability design with features ranging from showers for bicycle riders to support green travel, to a green roof to improve biodiversity.
“Kings Place” received the 2017 BREEAM Award in the Office In-Use category in March 2017.


“Silvers” in Düsseldorf receives LEED Platinum certification following revitalisation


The “Silvers” is the first existing property in Düsseldorf to receive Platinum rating – the highest level of LEED certification. An energy-oriented renovation introduced energy- and water-saving equipment and grey water use. High quality interior and exterior communication areas and additional green areas in the external grounds are used to create a pleasant environment.


“Skylight” in Frankfurt receives LEED® for Commercial Interiors Platinum certification.


“Skylight” is one of the first office buildings in Frankfurt am Main to be equipped throughout with LED lighting with daylight-dependent regulation. This decreases power consumption by around 70 percent, which is the equivalent to reducing CO2 emissions by 190 tonnes a year. The property received LEED® Platinum for Commercial Interiors certification.
