With the cluster project High Tech – Low Ex, a concept for an energy-efficient further development of the Berlin Adlershof science quarter was developed from 2011 to 2013 with the aim of achieving 30 % primary energy consumption compared with “business as usual”. Its implementation is taking place in sub-projects. With a running time of 2013 to 2016, the first follow-up project “Energy Strategy Berlin Adlershof 2020+” comprises the coordination, planning and networking of energy efficiency measures, in particular for further EnEff projects in Adlershof, the planning of an intersectoral energy infrastructure, the establishment of an energy manager with inter-site tasks, the development and use of quality and risk management tools, as well as collaboration with model districts in Germany, Austria and Switzerland (D-A-CH region) on the topic of “Energy hybrid systems”.

Project description
Project structure
WISTA-MANAGEMENT GMBH (state-owned operating company for the site) is responsible for coordinating the cluster and realising the project. The subsidiaries Adlershof Facility Management GmbH (AFM), and Adlershof Projekt GmbH (AP) as a fiduciary development agency of the State of Berlin, are supporting its implementation.
Project aims
The aim of the project is to develop an exemplary form of organisation for complex EnEff:Stadt projects, which would enable the optimisation and acceleration of innovative individual projects, and guarantee the overall success of the project “minus 30 % primary energy by 2020”. In addition, complex energy facilities for grid-bound energy sources that allow for an energy network in Adlershof are planned. This is taking place with the involvement of international experience and a thorough professional exchange with model districts in the D-A-CH region.
Follow-up projects
The application for the follow-up project “Energy Grid Berlin Adlershof” will soon be submitted by the Technical University of Berlin, the University of Applied Sciences Berlin, and Siemens AG. The aim of this project is to create a network of energy flows, a Smart Grid Alliance, and the associated energy planning guidelines.
Results of the concept phase
With the cluster project High Tech – Low Ex, a concept for an energy-efficient further development of the science quarter was elaborated from 2011 to 2013. The following results were achieved by the project:
- Inventory and analysis of energy infrastructure and supply; analysis of existing buildings and building-related implementation concepts for selected properties
- Forecasting of future energy demand (primary and final energy, German Energy Saving Ordinance and energy process engineering) of the entire area, including two development paths for the future development of the 47-hectare extension area
- Building summaries with suggestions for building performance optimisation for, amongst others, Helmholtz-Zentrum with BESSY II, four institutes of Humboldt University, Studio Berlin, and WISTA properties
- Scenarios for supply and transmission rights, and technical options for an open heating network
- Analysis and review of implementation options for waste heat technology (waste heat from refrigeration systems, brine networks, with the example of Max Born Institute)
- Cooling concept for “Bunsensaal” event building (including adiabatic exhaust air cooling)
- Concepts for building-related measures for four reference buildings (WISTA administrative buildings, the “Barracks”, Max Born Institute, and Lise-Meitner-Haus)
- Analysis and review of the potential contribution of renewable energy (wind, PV, shallow geothermal energy, deep geothermal energy, aquifer storage, CHP), with the result that aquifer storage, PV, biomethane and CHP should be implemented in light of primary energy savings and economic feasibility; a follow-up application will be submitted
- Preliminary investigations for a smart grid and a DMS connected to a ring circuit with 40 companies, 8 consumer units and 2 feed-in points with the result of submitting a follow-up application to implement this
- Analysis of building typologies for industrial, commercial and campus-like areas; follow-up application for pilot tests of the instrument of “Energy planning guidelines” to be submitted
- Development of a competence network at the site and beyond
- Development of an energy efficiency concept for the project area of Berlin Adlershof 2020 with a focus on “Primary energy saving measures”.
