For everyone who wants to build or renovate climate-efficient buildings . Worldwide.

Openly advises, trains and issues CO2 certificates.

    • Planning and construction cost savings through Building with a system (Motto: Not every architecture firm has to reinvent everything)

    • PlusEnergy:
      Increase in net rental income due to very low ancillary costs and ZEV. (see PlusEnergy yield properties by Valley Architects)

    • Yield:
      Buildings as C-sink
      Increase the yield (or reduce the construction costs) through the Openly CO2 certificates.

    • Circularity: Biogenic building materials are renewable, reusable or recyclable and represent a value at the end of their useful life.

    • Yield: Additional income from solar system and building control (software).

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

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

    • EU taxonomy
      Compliance with ESG criteria and internal company requirements

    • Better & healthier indoor climate for users

  • Openly creates CO2 balances and variant comparisons.

    Which variant (new replacement building, extension, extension) has which CO2 footprint and which operating energy?

    How can the concepts be optimized?

    What additional monetization and financing opportunities arise?

    Excerpt from a current consulting mandate for OOS Architects.

  • Our project support is provided on an hourly basis during the usual planning phases. The expenditure - over the entire construction phase - amounts to approx. 2% of the construction costs, whereby these are cost-neutral due to savings made by the planners.

    • Planning (and execution) is carried out locally by architectural firms.
      We help to set up the general planning team

    • This team receives free access to OPENLY Data with plans, proofs, suppliers and purchase prices

    • We accompany & coach the project throughout the entire construction phase and take on the role of client representative and project coaching.

    • We help with the creation of the building description &
      component catalog

    • We help with the selection of contractors and implementation on the construction site.

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

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

    • We retire the certificates for their insetting or place them on the voluntary carbon market.

  • The greatest leverage lies in the built environment. Renovations can also become a C-sink.
    Our consulting service for real estate portfolios and asset managers:

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

    • 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 create the CO2 certificates from your construction project for your insetting or sale on the voluntary carbon market.

  • Our subsidiary Valley Architekten AG specializes in the construction of apartment buildings as well as office and educational buildings and implements these projects as a general planner.

    • Ordering principle:
      Together with you, we define the CO2 reduction targets for your construction project

    • We complete your competition or tender documents.

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

    • We accompany the construction project as the client's representative and ensure that the team of architects and specialist planners reaches the finish line and adheres to the project specifications.

    • We calculate the CO2 balance of the construction project and provide the municipality with the resulting CO2 certificates for an insetting

  • As an architectural office, use the OPENLY construction system 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.

    If you would like to submit a project as a consortium, our subsidiary Valley Architektur AG is at your disposal.

Our guiding principle: Avoid CO2 emissions.

CO2 neutral construction

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

Zero emission operation

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

Durability
with value retention

Through the uncompromising use of high-quality materials, the focus on re-use & recycling, as well as a control dimension in the supporting structure, Openly engineered buildings are designed for a long and adaptive use.
