Munich: HVB Tower awarded LEED Platinum certification

Für die neue Gebäudehülle wurden insgesamt rund 2.500 Fassadenelemente ausgetauscht.

The corporate headquarters of HypoVereinsbank in the Bogenhausen district of Munich has been awarded LEED Platinum certification. The building received the highest score awarded in this category in Germany to date. Following comprehensive refurbishment, the building – which is over 30 years old – now meets the most stringent internationally established sustainability standard. Drees & Sommer’s role in the project includes real estate consulting, project management, engineering, and the conduct of LEED certification.

The first construction stage of the HVB Tower has already been completed. The facade of the 114-meter office tower was renovated within the space of three years, while modern work environments were realized in the interior. From the outset, the focus was on sustainability aspects, as well as on energy and space efficiency.

The existing heritage-protected facade was replaced by a new, multi-layered and multifunctional casement window facade that entirely preserves the appearance of the building. The inner shell comprises openable triple glazing. The frame element has inlet and outlet vents that allow natural ventilation of the offices.

The interior features a modern indoor climate concept that meets the high expectations of the users. Warmth in the groundwater is used for heating in winter, while in the summer the building is cooled by cold extracted from the ground. This is expected to reduce heat consumption by half and power consumption by about a quarter. Collectively, these measures have helped the HVB Tower achieve the highest LEED score in the 'New construction and major renovation' category and Platinum certification.

Drees & Sommer has been supporting the HypoVereinsbank with this project since 2010. It started with a feasibility study on which the remediation decision was based, after which the experts also took over the management of the project. As part of the energy rehabilitation, the company's Green Building team also undertook LEED certification. Drees & Sommer will continue to act as consultant to the HypoVereinsbank during the second stage of the project, which will be implemented through 2019.
