The real estate developer neuplan is planning a landmark project for the construction of sustainable office buildings in the Berg am Laim district of Munich. The property with around 30,000 m² gross floor area is to be characterised by future-oriented planning and carbon neutral operation. This includes flexible usage options and measures to increase resilience to climate-related changes.
Arup was commissioned with the building services engineering, the building envelope, lighting and acoustics design, as well as funding advice and sustainability and energy consulting.
Carbon neutral building operation
The energy performance for the operation of the office building is to be carbon-neutral. Air-water heat pumps in combination with photovoltaic systems on green roofs, façades and balustrades are to ensure a self-sufficient supply of heating and cooling. The degree of solar energy coverage generated by photovoltaic systems amounts to 37% of the total energy required. A significant amount of energy can be saved in the temperature regulation of the building through a mixture of natural and mechanical ventilation as well as heating and cooling ceilings that can be controlled according to demand.
Considering the effects of climate change in the planning
During the planning phase, making the building as climate resilient as possible was a major priority. Water retention and collection for heavy rainfall as well as risk of exceptionally hot weather are being addressed. Effective solutions, including green roofs, storage and use of rainwater for green space irrigation, and highly efficient heat pumps geared to the ever-higher outdoor temperatures, were all implemented to make this possible.
The buildings’ envelope consists of wood, glass and photovoltaic panels. The use of these materials depends primarily on the orientation of the façades. The aim is to make optimal use of both daylight and solar radiation ̶ which will increase in the coming years due to climate change.
With the surface optimisation of the individual façade components, including opaque and transparent surfaces, sun and glare protection, fixed and openable elements, the variation in the facades appearance represents the sustainable character of the building.
The highest possible sustainability goals are underlined by DGNB Platinum and WELL Platinum certifications. In addition, the WiredScore Platinum certification will ensure the highest standards of IT for the tenants. These certifications will be implemented during the project development.
