Environmental certification for climate resilience and sustainability
In addition to intensive greenery to enhance thermal comfort in the courtyard and gardens, the planning process also focused on rainwater management and biodiversity. Large unsealed areas, combined with extensive green roofs and retention boxes, ensure that not a single drop of rainwater flows into the sewage system.
A diverse selection of plants and vegetation structures, along with the installation of a bee hotel on the roof, actively promote urban biodiversity. Furthermore, the targeted use of ground-based façade greening helps to reduce and improve thermal storage capacity.

The greenpass Certification aligns with our strategy for developing future-proof, sustainable real estate. Especially in times when adapting to climate change is becoming increasingly important, the greenpass Certification has shown us the small details that can make a big difference.

Through the use of simulation-based analyses, the environmental impacts of the property were holistically optimized during the planning phase with greenpass. In particular, the qualities in the areas of climate and energy were significantly improved through a collaborative process. Simple measures, such as additional shrubs and trees, as well as their strategic placement, help reduce the air temperature on a typical hot day by up to -0.3°C. By reducing the thermal load score, the project also has a positive impact on the urban climate.
The project also demonstrates high thermal comfort, which was improved compared to previous designs, resulting in a temperature reduction of up to -16.9°C in perceived temperature. Additionally, the water demand for plants was reduced during the optimization phase, while CO₂ storage was increased. The approximately 0.4 hectares of green space and over 40 trees sum up to nearly one hectare of leaf surface.
In the bonus topics of biodiversity, resources, and social impact, the project also makes significant contributions, such as community areas, barrier-free outdoor spaces, smart lighting concepts, the prevention of animal traps, and the use of regional and ecological materials in garden and landscape design.

First greenpass Gold in Germany
Just as a passport serves as an official identification for people, the greenpass acts as an official confirmation document. The greenpass transparently summarizes the climate resilience and sustainability of real estate and their open spaces.
The climate-fit residential complex in Frankfurt am Main achieved a certification level of 76% after successful optimization, earning greenpass GOLD.

Conclusion
Not only for successful climate change adaptation are future-proof and sustainably designed developments essential, but also in the responsibility of developers to demonstrate the environmental impacts on the population, residents, and the city. Greenpass is consciously an active tool and communication medium during and after the planning process and implementation, showcasing the many contributions of buildings, materials, and plants to the environment and to us humans. With KUHLIO, SRE is taking a pioneering role in sustainability and demonstrating how contemporary, climate-active, and future-proof properties can be designed.
