What EFFEKT does

EFFEKT Arkitekter ApS is a Copenhagen-based, privately held architecture and research collective founded in 2007 by Sinus Lynge and Tue Hesselberg Foged. The firm employs 50+ multidisciplinary experts — architects, landscape architects, urban planners, and researchers — and delivers architectural design, urban planning, landscape architecture, and transformation projects at every scale, from furniture and housing prototypes to multi-hundred-hectare city masterplans.

The firm's core technology stack centers on science-based, open-source research frameworks — the Reduction Roadmap and its Butterfly Framework evolution, the Doughnut for Urban Development manual, and the Urban LCA tool — co-developed with academic and industry partners (Stockholm Resilience Centre, DEAL, Aalborg University, DTU, CEBRA, Artelia, Frederiksberg Kommune, and others). These frameworks translate the Paris Agreement and planetary boundaries into industry-specific CO2 reduction and biodiversity targets for the building sector, with documented outcomes such as a 3x lower CO2 footprint in Living Places Copenhagen (3.85 kg CO2/m2/year vs. 12 kg/m2/year Danish baseline), an 81% material-impact reduction for CPH Metro surfaces, and the mobilization of 600+ companies and municipalities for regulatory alignment.

EFFEKT operates a professional-services, project-based revenue model, acquiring work through open and invited design competitions, direct commissions, and public tenders from a diversified client base spanning Danish municipalities, real estate developers, cultural and educational institutions, corporate partners (e.g., VELUX, Better Energy), and international clients across 10+ countries. Research initiatives are funded separately by major Danish foundations including Realdania, Villum Fonden, and Dreyers Fond. The firm has expanded its leadership to four partners (2023), partners with CREE Buildings on the modular Biome housing product, and maintains international recognition including a Golden Lion at the 2006 Venice Biennale and the Nykredit Sustainability Prize.

Core offering

EFFEKT is a Copenhagen-based architecture and research collective providing architectural design, urban planning, landscape architecture, and applied research services. It develops and applies proprietary research frameworks (such as the Reduction Roadmap and the Doughnut for Urban Development) on housing, urban development, and sustainable design projects for municipalities, real estate developers, cultural institutions, and industry clients.

Product overview

EFFEKT is an architecture and research collective that offers a portfolio of architectural design services and research frameworks rather than a unified software product. Their core offering includes architectural master planning and design services across residential, cultural, educational, and public realm projects. Alongside traditional architecture services, they provide open-source research tools and frameworks including the Reduction Roadmap (climate-aligned building targets), Doughnut for Urban Development (planetary boundaries framework), Urban LCA (life cycle assessment tool), and the Compass Model (sustainable design guide). Their Living Places concept and Biome modular housing system represent proprietary approaches to sustainable development that combine architectural services with methodological frameworks.
