Sustainability

Carbon neutrality

From day one, planning for the Siemens Campus Erlangen has focused on sustainability. 

All new buildings will be equipped with modern building services engineering and energy technology This will include implementing a broad number of solutions from Siemens' environmental and sustainability portfolio. Consistently combining and integrating state-of-the-art digital technology such as smart building applications and an intelligent smart-grid-based network connection will increase the sustainability of every building and the entire location. Our goal is to achieve LEED Gold certification, an internationally recognized standard that is only awarded to the most environmentally friendly, resource-efficient and sustainable new buildings. 

What's more, all office buildings and the Reception Building to be erected within Module 2 will be particularly sustainable and innovative structures of timber-hybrid design. This reduces the embodied carbon emissions of building construction by 80%. 

Moreover, Siemens has joined forces with the municipal utility of Erlangen to implement a district cooling and heating plan that will also enable the completed Siemens Campus Erlangen to be operated carbon-neutrally – in line with Siemens' goal to be one of the first major corporate groups worldwide to achieve climate neutrality by 2030. The location's electric power supply is to be sourced entirely from wind power, and is thus also 100% carbon-neutral. 

The biodiversity of flora and fauna in this new district of Erlangen will also benefit from the 160 new native pine, oak and poplar trees as well as exotic ginkgo trees already planted just within Module 1 alone, in addition to the 75 existing trees in the site's mature stands. Siemens is planting even more trees here than considered necessary so that the Siemens Campus Erlangen – the company's first carbon-neutral location anywhere in the world – entices passersby to relax and linger a while in the spacious outdoor areas and green spaces. 

Wood instead of concrete

The Siemens Campus Erlangen is a project that is continuously further developing. Such progress begins already with the type of construction being used, as building materials are advancing as well. 

The central Reception Building and four new office buildings of Module 2, for example, will be of a timber-hybrid design particularly sustainable and innovative in its construction. 

In such buildings, the load-bearing structural elements are of prefabricated in steel-reinforced concrete, while most of the building is constructed from wood. Before actual construction work begins, a virtual replica called a "digital twin" is generated of each building. For buildings of timber-hybrid system, this process – also known as building information modeling (BIM) – enables extensive industrial prefabrication of what in many cases are standardized building elements, including some pre-installed service-system supply lines. 

This reduces the embodied carbon emissions of building erection by 80% compared to conventional concrete structures, cuts the volume of concrete used by two thirds, and reduces the complexity of building services engineering. This latter advantage reduces maintenance cost and effort after building completion, and thus also the cost of running operations which can then actually be reduced even further thanks to the digital twin. 

Incidentally, timber-hybrid system is so new that Module 2 of the Siemens Campus Erlangen marks the very first time this technique is being applied on such a large scale. 

E-mobility

The Siemens Campus Erlangen will be setting whole new standards not just for its attractive campus structure and state-of-the-art working environments: sophisticated mobility planning and management aim to make the location a beacon of accessibility that shines across the entire metropolitan region. 

The e-mobility of the future plays a very special role in this conceptual planning. For example, the parking garages in Module 1 are already equipped with 50 charging stations for electric cars, and another 50 charging stations will soon be added. They also offer some 50 charging stations for e-bikes. 

More charging stations for electric cars and bicycles will be provided in Module 2. 

Sustainability and biodiversity

Numerous innovative processes, measures and applications will be used at the Siemens Campus Erlangen to achieve the carbon neutrality that Siemens is striving to reach. Such efforts begin with a holistic, systematic concept and ranges from comprehensive mobility planning and painstakingly sustainable development to minimizing water and energy consumption and using particularly healthy and resource-efficient materials. 

Biodiversity 

Sustainable, ecological and diverse – environmental aspects play a prominent role in planning and implementing the Siemens Campus in Erlangen. 

Nature conservation and biodiversity occupy an important position along with state-of-the-art building and energy technologies, environmentally friendly design, innovative district cooling and heating concepts, as well as the use of renewable energy. Consequently, not only are existing trees being kept, but additional new pines, oaks and poplars as well as ginkgo trees are being planted that thrive particularly well under the local climatic conditions in city centers.

All of the efforts taken to promote and preserve biodiversity on the Siemens Erlangen Campus are summarized in a comprehensive Biodiversity Brochure.

Energy

  • Thanks to its carbon-neutral energy supply concept, energy use on the Campus will be 35% lower than required by Germany's Energy Saving Ordinance (EnEV). 
  • Photovoltaic solar power systems for generating electricity will be installed on many of the buildings roofs. Just the systems installed in Modules 1 through 3 alone will produce some 1,175 megawatt-hours of electric power every year – enough to meet the demand of some 400 households. 
  • The entire Campus will be supplied with certified climate-neutral green power from physically allocated wind turbines operating in Germany. 
  • An agreement was concluded with Erlangen's municipal utility company to cool and heat the Siemens Campus Erlangen by climate-neutral energy production systems. A combined heat and power plant that cogenerates electricity as well as thermal energy for district heating and cooling is being erected next door to the Campus. 
  • In each building, the thermal storage mass of the building's structures will be activated, enabling additional energy savings to be achieved in combination with radiant heating and cooling ceiling systems and intelligent building services engineering and automation. 
  • The buildings are ventilated in part by automated systems that include heat recovery and needs-based control of the air flow quality utilizing appropriate sensors, weather data and presence detection. 
  • The innovative "Siemens Navigator" is used to optimize the operating conditions of the buildings' service systems to allow comprehensive, end-to-end energy management that considers all data from the building service systems. 
  • The office spaces are equipped exclusively with efficient LED luminaires that are automatically controlled on the basis of daylight and presence. 

Green spaces and parks

  • The developed outdoor areas and surfaces are designed to be environmentally compatible such as to minimize their impact on the local microclimate. 
  • The currently existing green spaces and their stands of trees are being extensively retained. Once completed, Modules 1 and 2 will be home to many more trees than were there before. 
  • The outdoor areas and green spaces are being planted with greenery featuring native plants fitting to the location, including a traditional "Franconian orchard" to the benefit of the local insect world. 
  • Many of the building rooftops will be planted with greenery and utilized for green-roof rainwater retention. This also serves to reduce buildup of heat in buildings exposed to strong direct sunlight. Rainwater will also be partially collected in storage tanks to water the green spaces. 
  • Thanks to the use of grass pavers, the developed grounds are not sealed at the surface. In addition, the site's own dedicated runoff storage sewerage system takes some of the burden off the public stormwater runoff network. 
  • Outdoor areas are only illuminated at specific locations to reduce light pollution and protect nocturnal wildlife. 

Construction and buildings 

  • Rules governing waste segregation are being strictly observed already during demolition of the older existing structures as well as during all new construction work. The current recycling rate is at a record level of over 90%. 
  • All building materials used are low-polluting, low-emission materials and substances, and all of the wood is certified. Preference is given to using regional building materials and resources as well as renewable raw materials. 
  • Many of the workstations in the new, highly insulated buildings are situated at windows to allow occupants to make optimum use of daylight. Outdoor window blinds automatically prevent occupants from being blinded by direct sunlight, while also preventing interior temperatures from rising too high. 
  • Drinking water demand is minimized by water-saving valves, continuously monitored and optimized. 
  • The indoor air and environmental quality are continuously monitored and optimized based on presence detection. 
  • Even for office furniture, only especially sustainable upholstery fabrics are used: made either from the natural virgin wool or synthetic fabrics manufactured 100 percent from first-time recycling materials – principally from melted-down plastic bottles made from PET – and subsequently woven into fabric. 
  • A business location that sets whole new standards for sustainability is thus being created by also implementing comprehensive building automation and monitoring systems fitted with state-of-the-art sensors and collected data evaluation by innovative Siemens solutions such as "Siemens Desigo" (for automation), "Siemens Navigator" (for energy management) and "Siemens MindSphere" (for data evaluation). 

Certifications

All buildings on the Siemens Campus Erlangen are being designed, planned and built for optimum sustainability, and will then be operated over their entire service lifecycle accordingly. This enables our buildings to achieve certification to the global LEED Gold standard. 

The internationally recognized LEED system is a certification process applied worldwide that defines a series of standards for environmentally friendly, resource-conserving and sustainable planning, construction and operation of buildings. The acronym LEED stands for Leadership in Energy and Environmental Design. 

The LEED Gold standard is only awarded to particularly ecofriendly, resource-efficient and sustainable new buildings. 

Honored with sustainability prize

The Siemens Campus Erlangen is the only project in Erlangen and one of only three in the region to be awarded the 2021 prize for "Sustainable Business Parks and Commercial Properties" by the Nuremberg CCI for Central Franconia. 

The CCI's jury of experts paid tribute to the Campus' "holistic sustainability concept offering employees a comprehensive range of services, amenities and mobility opportunities, as well as the wood-hybrid construction." The space-efficient design of the Campus and the greening of its building facades and roofs also received special recognition.

Conservation of the species and ecosystems also plays an important role in this concept. The Siemens Campus Erlangen has drawn together all these efforts in a new Biodiversity Brochure, available now to browse and read through at your leisure.
