For all those who want to build or renovate net zero buildings. Worldwide.

Build economically, ecologically, openly

    • Return on investment: Planning and construction cost savings through building with a system (motto: don't reinvent everything)

    • Return on investment: building ecologically is not more expensive

    • Yield: Increase in net rental income due to very low ancillary costs (PlusEnergy building)

    • Yield: additional income from solar system. The building as a power plant; sale of energy to users in the building

    • CAPEX: Longer payback period due to building useful life & flexibility

    • Annual CO2 sink for your operational CO2 balance through PlusEnergy buildings (insetting)

    • Buildings as C sinks
      CO2 certificates from the construction and refurbishment of own buildings (insetting / compensation)

    • Yield: Sale of CO2 certificates via OPENLY Markplace

    • Fulfillment of ESG criteria and in-house strategic requirements

    • Better & healthier indoor climate for users

    • Customers want to see concrete, credible and comprehensible actions

    OPENLY briefly summarized:

    We focus on avoiding CO2 emissions in the construction industry. By using innovative ecological building materials and approaches, we avoid around 70% of the usual emissions in the construction process. The philosophy encompasses more than just the building itself; it is about rethinking architecture, moving away from purely design aspects towards a functional, environmentally conscious perspective.

    Buildings are seen as future CO2 reservoirs. By using materials such as straw or hemp, which bind CO2 as they grow, buildings can become net-zero or even CO2-positive structures. These materials are used as insulation in buildings and thus contribute to the storage of CO2. The innovative concept offers a natural alternative to mechanical CO2 storage technologies and underlines the potential of nature in the fight against climate change.

  • Our project support:

    • Together we define the scope, goals and framework conditions of your new construction project

    • According to the motto "start right", we prepare a preliminary study including a rough cost and component catalog as a basis for your decision and investment.

      Implementation with the OPENLY construction system (consulting costs approx. 2% of the construction costs):

    • The planning is done locally. We help to set up a general planning team with architecture and specialist planners.

    • We offer training & team building for your project team: OPENLY Academy

    • Free access to OPENLY Data with plans, proofs, suppliers and purchase prices

    • We accompany & coach the project throughout the entire construction phase and represent the client.

    • We create a building description &
      component catalog

    • We prepare the CO2 balance:
      - At the time of building application
      - After completion of construction incl. data for further certifications (LEED, etc.)

    • We procure the CO2 certificates for carbon storage in your property.

    • We delete the certificates for your insetting or sell them on the market via the OPENLY marketplace

    • We are happy to mediate in the financing of multi-family house projects.

  • Hourly advisory services for real estate funds and asset managers:

    • We carry out an assessment of one of your recently completed refurbishment projects and draw up a CO2 balance sheet.

    • We create a strategy & implementation concept for future refurbishments in line with your reduction targets

    • We accompany & coach the next renovation project and provide the construction system

    • We prepare the CO2 balance after completion of construction

    • We procure the CO2 certificates from your construction project for your insetting or sale on the market via the OPENLY marketplace

  • Would you like a detailed CO2 balance for a current or completed construction project?

    Our life cycle assessmentteam of specialists will be happy to provide you with a detailed Scope 3 balance sheet (i.e. including the production, transportation and installation of building materials) on an hourly basis

    We help you interpret the data and work out the fields of action, in particular the possibilities of insetting your own construction activities. This area is particularly exciting for listed companies (EU taxonomy).

  • Together with you, we draw up an ecological building contract and define the scope of services(see checklist).

    We help you to select a local architectural firm and, where required, provide our external team of specialist planners.

    In the planning and realization phase, we support your project on an hourly basis.

    We are happy to help with the financing of multi-family house projects. If required, we can also create the entire residential complex as a TU for private developers.

  • Would you like to be the first federal state, canton or city to construct a CO2-neutral building?
    (consulting services on an hourly basis)

    • We prepare competition and tender documents.

    • We support the evaluation of the project winner and prepare a realistic construction cost estimate for the winning project

    • We accompany the construction project as the client's representative and ensure that the team of architects and specialist planners reaches the finish line (net zero).

    • We calculate the CO2 balance of the construction project and provide the municipality with the resulting CO2 certificates (insetting).

  • As an architectural office, use the OPENLY construction system openly for your competition entry. We support you in the areas of components, verifications, construction cost calculation and circular economy and sustainability. (see OPENLY Data)

    Depending on the size of the competition, we may also be able to get our network of specialist planners interested in your submission.

OPENLY is like a virus, because wherever an OPENLY is built, an entire ecosystem of specialist planners, suppliers and contractors develops that build CO2-optimized and fossil-free. The name OPENLY was chosen very deliberately - sharing and openness are the key and our core motivation. It is a contribution to the "building turnaround" that you - and we - are making.

Our guiding principle: Avoid CO2 emissions.

CO2 neutral construction

Thanks to the use of low-CO2 building materials, some of which also store CO2, our houses are already low-CO2 or even net zero during construction.

Zero emission operation

Due to the good insulation values, the high storage mass, reduced window areas, the use of photovoltaics and our intelligent energy management system (OPEN SYSTEM©), our houses reach PlusEnergy standard.

Durability
with value retention

With uncompromising use of high-quality materials, a focus on reuse and recycling, and a regulation scale and above-average ceiling heights, our buildings are designed for long and adaptive use.
