The office building of the Nord/LB Bank that was built in 2002 became a landmark of Hannover. A huge proportion of the building is naturally ventilated. The interior is designed with progressive energy concept with superstructure exposed and windows that provide ventilation. The building is also protected from noise and vehicle emissions through the areas of double façade, which also serves as a duct transferring clean air from the central courtyard to the individual offices. The reflection of daylight is increased through the large areas of water in the courtyard which also contributes towards a beneficial microclimate. The building is also equipped with generous roof gardens which not only provides aesthetic benefits but also improves the general climate for the occupants, and collects rainwater for irrigation and use within the building. The building is owned by Norddeutshce Landesbank and was designed by BEHNISCH, BEHNISCH & PARTNER (Reference 2).

Focus
Creation of new green areas
Project objectives
To provide an environmentally conscious and convenient working environment (Reference 1) among others with the help of:
- green roofs: to improve the general climate for the occupants, and to collect rainwater for irrigation and use within the building" , and to soften its appearance (Reference 2)
- pond: to increase the reflection of daylight and contribute towards a beneficial microclimate" (Reference 2)
-Areas of ‘double facade’: to provide protection against noise and vehicle emissions, whilst also serving as a duct transferring clean air from the central courtyard to the individual offices (Reference 2)
Implementation activities
- implementing a 1500 m2 large intensive green roof with 25 cm thick intensive substrate that is planted with herbaceous perennials
- implementing an altogether 3500 m2 large extensive green roof on 13 surfaces with approximately 11 cm thick extensive substrate that is planted mostly with sedum species and flower bulbs
- supporting the green roofs with a drainage system that ensures balanced water / air supply and adequate draining (Reference 3)
- a 3000 m2 large pond was created in the courtyard (Reference 1)
Climate-focused activities
Climate change adaptation:
- Implement green walls or roofs to lower indoor temperature and provide insulation
- Implement sustainable urban drainage infrastructure (e.g. to make space for water)
