The ultimate energy-efficient high-rise
In collaboration with Studio Vulkan and ARUP, OSA has planned a 65-metre-high building on Rosenheimer Straße in Munich. The core structure of the existing office building, which was constructed in the 1970s, will be retained and extended by two additional volumes. The building will be clad with a facade of green photovoltaic louvres, which generate around 25% of the building's energy requirements.
The East Gate building complex can be realised as a low-energy building with the extremely high energy efficiency standard EG 40 in combination with the goal of net zero emissions in operation. To achieve this, the highest efficiency standards for buildings and technical building equipment are set and combined with the maximum use of on-site renewable energy (RE), such as solar energy.
Proven passive strategies are used that take advantage of local climatic conditions: Green roofs to reduce the heat island effect, natural or mixed ventilation and the use of adiabatic cooling for ventilation. The digital and smart building strategy also serves to further increase efficiency, minimise hot water, heating and cooling needs, provide efficient low-temperature heating and supply high-temperature cooling mainly through electric heat pumps incorporating environmental heat.
Passive design optimisation and high performance envelope: optimising the building form and envelope to primarily reduce energy demand and the need for an active system.
Building automation and tenant engagement: Reduction of energy demand through intelligent control systems and tenant engagement to achieve the overall goals of the project.
Efficient building services solutions: Requirements and measures to use the best strategies in the field of energy efficiency with the aim to prioritise sustainable low-tech solutions and efficient active systems (e.g. low-temperature systems for heating, uncontrolled dehumidification,..)
Electrified supply: Requirements, measures and potential technologies to aim for a clean, emission-free energy supply concept that enables the main goal of a climate-neutral building to be realised
Renewable energies: Requirements and measures and implementable technologies to maximise the use of on-site renewable energy sources for thermal and electrical supply and for the procurement of project-specific renewable energy to meet the remaining electricity demand (e.g. PPAs, integrated PVs).
