Cities and urban areas are where global issues are decided: Climate change, social justice, healthy living and working of the future. The real estate industry plays a significant role in answering these questions. We make an active contribution on the way to a sustainable, resilient and livable city. And we can only be successful in the long term in a stable economic environment if we pay attention to the overall well-being of the environment and people.

As a property developer and investment manager, the responsible use of people and resources is of utmost importance to us. We have set ourselves important sustainability goals in ethical, social, ecological and corporate terms. We focus on three areas here: Environment, Social and Governance (ESG). These ESG criteria are firmly embedded in our corporate culture and form the basis for corporate governance that is aligned with strong values.

ESG Scoring

We want to make future viability measurable: In order to reliably analyse social and ecological criteria of a property we have developed Quantum ESG scoring. This enables us to systematically consider criteria such as CO2 emissions, resource conservation, social tenant management, healthy living and working or combating inequalities when making investment decisions. We can therefore evaluate opportunities and risks on a property-specific basis.

Modern and healt­hy working environments

Sustainable, healthy office environments are part of a sustainable property economy. New information and communication strategies make it possible to work across spatial boundaries, and flexible office concepts are becoming more and more important. We support mobile working and the smart office concept to reduce the environmental impact, achieve better energy efficiency, and focus on holistic building concepts that create healthy working environments. Not least, the urban environment with its diversity of facilities and broad mix of uses also plays an important role.

Social housing

For us, a focus on sustainable property management also means social and target-group-oriented housing provision. In our investments and developments, for example, we pay attention to flexible and accessible building structures and a balanced mix of housing in an environment characterised by a variety of uses. Ensuring affordable housing and social tenant management are just as much a part of social housing provision as housing solutions for single-person households, families, older people or people with special needs.
