    Allreal creates value through long-term business activities geared towards sustainability

    Allreal has developed a sustainability strategy (ESG) that sets ambitious and specific goals and can be measured against these annually in the future. Allreal creates value through full CO2 neutrality (Environment) By 2050 at the latest, Allreal aims to achieve full CO2 neutrality for its investment property portfolio. By the end of 2022, the company will therefore ensure full consumption recording of the investment properties and develop individual property strategies. In addition, the company will start a broad-based expansion of photovoltaic systems and building management systems. In order to achieve the reduction path, partial compensation of the CO2 emissions will be made from 2022. The active control of user behavior should make a further contribution to lowering emissions. In addition to “green lease” contracts, there is also the promotion of electromobility and the creation of financial incentives to encourage sustainable user behavior among tenants. By the first half of 2024, at least 20% of the garage parking spaces will be equipped with an electric charging station (800 charging stations).


    With a view to the activities of general contracting, Allreal relies on the consistent use of reusable materials. In the case of in-house projects, the entire life cycle of a material is taken into account as quickly as possible. Allreal creates values by assuming responsibility (social) In the area of society, Allreal advocates comprehensive occupational health and safety as well as real equal opportunities. The company already offers an attractive working environment which, thanks to the flexibilisation of working hours (part-time work / partial retirement), enables work and family to be reconciled. Further related measures are being expanded on an ongoing basis.

  • Milestone for sustainable building is being created in Zug

    Milestone for sustainable building is being created in Zug

    The construction project for V-ZUG ‘s new production and assembly building called Zephyr Ost in the Zug Tech Cluster is the largest to date in which CO2-enriched concrete has been used. It is made from recycled concrete from the building materials group Holcim , which is enriched with CO2 using a neustark process. According to a press release , the construction work started on Wednesday. The building is scheduled to go into service in 2023.

    For this climate-friendly concrete, CO2 from Switzerland is being used for the first time. The start-up based in Bern and spun off from the Swiss Federal Institute of Technology Zurich ( ETH ) in 2019, neustark extracts the CO2 from the wastewater treatment plant of the ara region Bern AG .

    The recycled granulate for concrete production is processed by the recycling processing plant Arge EvoREC in Oberdorf NW. This is a joint venture between Holcim Kies und Beton AG and Zimmermann Umweltlogistik AG . The granulate is then carbonated by neustark using the dry process. The technology has been tested in the past few months and is now being used commercially.

    With the use of 4,200 cubic meters of recycled concrete and the binding of CO2, a total saving of 71 tons of CO2 is achieved compared to conventional construction. That corresponds roughly to the annual CO2 uptake of 3500 Swiss firs.

    “We are pleased to be able to come one step closer to our vision of climate-neutral and circular concrete production with the help of the innovative neustark process,” said Giovanni Barbarani, Head of Concrete Performance at Holcim Switzerland. “This project is a milestone on the way to sustainable building in Switzerland, also thanks to its regionality and short transport routes.”

    The Metall Zug Group wants to create “a new piece of the city for an industrial ecosystem” in the Zug Tech Cluster. Other industrial companies, start-ups, technology-related service providers, training institutions and apartments are also to be located there.

  • Swiss Life Arena produces ice in a CO2-neutral way

    Swiss Life Arena produces ice in a CO2-neutral way

    The Swiss Life Arena should be “a showpiece in terms of energy efficiency”, writes the electricity company of the city of Zurich ( ewz ) in a press release . It created the energy concept for the ice rink in Zurich Altstetten. “We have incorporated our many years of experience in the planning, implementation and technical operation of arenas such as the Hallenstadion in Zurich, the Swisspor Arena in Lucerne or the Vaudoise Arena in Lausanne,” says Christoph Deiss, Head of Energy Solutions at ewz Communication cited.

    The heart of the concept is the arena’s energy center, which produces the cold for the ice surface and the energy for the indoor climate. The waste heat produced by the four refrigeration machines is used on the one hand to heat the rooms. On the other hand, the arena is to be connected to the Altstetten and Höngg energy network. In this way, the waste heat from the refrigeration machines will contribute to the heat supply of households connected to the energy network in the future. “We decided on an energy concept from ewz that guarantees ecological sustainability,” said Peter Zahner, CEO of the ZSC Lions , in the message. “We were particularly impressed by the innovative approach to utilize synergies – not least from an economic point of view.”

    In order for the Swiss Life Arena to meet the Minergie standard for ice arenas, a photovoltaic system with an output of 400 kilowatts peak will also be installed on the roof of the stadium. Heating and cooling as well as the electricity additionally supplied by ewz are produced “100 percent CO2-free”, writes ewz. A building automation system should control the systems in a demand-oriented and energy-efficient manner.

  • Umwelt Arena implements lighthouse project in Urdorf

    Umwelt Arena implements lighthouse project in Urdorf

    The development of the Umwelt Arena in Männedorf received the Watt d'or 2021 from the Federal Office of Energy. The two multi-family houses in Männedorf can cover their energy needs with photovoltaic modules on the facades and roofs and two wind turbines. This means that your residents are exempt from electricity and heating costs up to an upper limit.

    The Umwelt Arena is now following up with a new lighthouse project. In Urdorf, three more energy self-sufficient residential buildings are to be realized, is explained in an article on energeia + . The blog of the Federal Office of Energy will accompany the implementation of the project in a loose series of articles. In the first article, Walter Schmid, investor and initiator of the Umwelt Arena, explains the planned development.

    As in Männedorf, the buildings in Urdorf will also produce their own energy, explains Schmid. “Photovoltaic systems are installed on the facade, on the flat roof or the entrance to the underground car park.” Excess energy produced in summer is to be fed into the gas network and withdrawn in winter. In order to convert the gas back into electricity and heat, a hybrid box will be installed in the basement of the building. The tenants of the residential buildings are to be exempted from electricity and heating costs up to an upper limit.

    In the brochure for the project, the development in Urdorf is referred to as a “national future project”. Because the project should show "that it is worthwhile to build energy-efficiently and win everyone in the process," says the initiator Schmid. Männedorf has already shown that the idea works, that the larger project in Urdorf should "make it even cheaper, more economical". Because this is the only way to attract imitators.

  • Buildings of the Zurich city administration will be CO2-neutral

    Buildings of the Zurich city administration will be CO2-neutral

    According to a media release from the City of Zurich, all of the properties owned by the city administration are to become CO2-neutral by 2035. City Councilor André Odermatt (SP), Head of the Building Construction Department, presented a strategy for this this week.

    According to the announcement, a large part of the operating emissions can be traced back to fossil heat generation. Among other things, all fossil heating systems should therefore be replaced by alternative heat sources. The heat will come from heat networks or district heating systems. Further measures include technical innovations, improvements in energy efficiency and changes in behavior.

    The portfolio of Immobilien Stadt Zürich (IMMO) includes school complexes, office buildings and workshops. Since 2007, thanks to various measures, it has already been possible to more than halve the buildings' annual CO2 emissions by around 23,000 tonnes to around 20,000 tonnes. A reduction of 90 percent is to be achieved by 2030, before the buildings become completely CO2-neutral in 2035.

    “The goal is ambitious, but the size of our portfolio with around 1,800 buildings also obliges us to set ambitious goals. IMMO can make a significant contribution to urban climate policy, ”Odermatt is quoted as saying.
