Gaining certification for 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.
In this context, property sustainability certificates allow compliance with sustainability criteria to be measured and compared in accordance with nationally established and internationally recognised certification systems.
These include the three best known and most widely used systems for end-to-end building assessment: BREEAM (Building Research Establishment Environmental Assessment Method), LEED® (Leadership in Energy and Environmental Design) and the German Sustainable Building Council (DGNB) .
The French sustainability certificate HQE (Haute Qualité Environnementale), which is also based on a comprehensive ESG building assessment, has now become known outside France as well. In addition, the topic of health and well-being is gaining in significance. WELL certification enables properties to be designed and optimised so that they create a healthy and comfortable environment for people who spend time in them.
Excellence in sustainability: The Edge, BREEAM Outstanding.
Deka Immobilien’s portfolio includes The Edge – one of the most sustainable office buildings in the world.
In a time when using resources sustainably, reducing CO2 emissions and paying attention to health and well-being are more important than ever, certifications are becoming increasingly significant. In recent years, various certification systems for sustainable buildings have been developed on the basis of the three pillars of sustainability: the environment, the economy and society. The range of assessment criteria used in these systems provides a form of guidance. Around the world, there is a large number of certification systems with a wide range of approaches and objectives.

BREEAM, LEED® and DGNB are the main sustainability certification systems in Europe. The evaluation is based on a variety of criteria that assess the sustainability performance of buildings in a structured manner. The HQE sustainability certificate was launched in France in 2005. As a result, HQE certifications are mainly awarded there. These building certification systems are based on an end-to-end assessment of sustainability performance. To reflect the changing legal framework, the most recent updates focused more strongly on life cycle, resilience and climate neutrality. Economic aspects also play a major role in the DGNB’s evaluation, and an attestation of conformity with the EU Taxonomy can also be obtained at the same time as the certification. The EU Taxonomy generally forms part of all widely used certification systems in Europe.
The WELL Building Standard, which has been awarded since 2014, focuses primarily on the health and well-being of users. Other certification systems dedicated to specific topics have emerged in recent years, such as WiredScore, which assesses a building’s digital connectivity, or net-zero carbon certifications, to name two examples.
Examples of sustainably certified buildings here
BREEAM stands for Building Research Establishment Environmental Assessment Method. This certification system was developed in 1990 in the United Kingdom (UK) by BRE Global Limited (UK 1990). Founded in 1921, BRE is an independent UKAS-accredited research and certification body and a subsidiary of the BRE Trust. It launched the first certification systems on the market in 1990.
Since their launch on the market, more than 2.3 million buildings have been registered and over 600,000 certified. BREEAM currently operates in 93 countries. BRE Global Limited is the system provider for BREEAM in the United Kingdom and other countries. It is mainly responsible for the development of the BREEAM system variants. The company also has partners around the world known as National Scheme Operators (NSOs), which are granted an exclusive licence by BRE Global to develop country-specific BREEAM systems. This involves adapting existing versions of BREEAM systems to reflect local regulations, taking into account standardisation, legislation and the building culture while ensuring comparability with the international BREEAM standard. There are currently five NSOs in Europe. TÜV SÜD Industrie Service GmbH in Frankfurt am Main became an exclusive licence partner of BRE Global in October 2016, making it the sole standard-setting body for BREEAM systems in Germany, Austria and Switzerland. There are other NSOs in the Netherlands, Sweden, Norway and Spain.
Depending on the desired level of certification, various minimum requirements must be met. As a rule, new construction and renovation projects, existing buildings, districts and infrastructure projects can be certified. Residential buildings are covered by a dedicated system known as Home Quality Mark.
Ratings are based on the degrees of fulfilment, which are indicated by stars. Depending on the degree of fulfilment, 1 to 5 stars are awarded for new buildings, and 1 to 6 stars for modernisations and existing buildings.
BREEAM rating for existing buildings
BREEAM rating for new buildings and modernisation projects
The BREEAM assessment system for new buildings includes nine main categories and an additional category for innovations. BREEAM covers all the life cycle phases of properties in accordance with the Code for a Sustainable Built Environment.
This category encourages the adoption of sustainable management practices in connection with design, construction, commissioning, handover and aftercare activities. Optimising projects on the basis of their forecast life cycle costs is an important part of this category.
This category is used to rate the comfort, health and safety of building occupants.
The energy criteria are aimed at promoting energy-efficient building solutions, systems and equipment and reducing CO2 emissions, especially through the use of renewable energies.
The criteria in this category rate the location and location infrastructure, e.g. proximity to public transport and local amenities. The implementation of alternative transport solutions is also encouraged.
This category is aimed at reducing the consumption of drinking water by using the most water-efficient equipment indoors and outdoors and utilising rainwater and grey water.
The criteria in the materials category encourage decisions that reduce the negative environmental impacts of the construction materials used during design, construction, maintenance and repair.
This category is used to rate sustainable management of construction and operational waste.
This category encourages sustainable land use, habitat protection and the improvement of biodiversity at the location.
This category rates the prevention and control of pollution and surface water run-off associated with the building’s location.
This category rewards exemplary performance and innovation.
For the purpose of assessing existing buildings, the additional categories of resources and resilience were introduced with the current system variant v6 in order to promote the circular economy and adaptation to climate change.
