Sustainability

Construction has exceeded the planet’s limits, defined by the Planetary Boundaries – seven of which have already been exceeded globally. The construction industry accounts for 39% of global carbon emissions and is the world’s largest consumer of materials. As such, it is a major driver of climate change and biodiversity loss.

At CEBRA, we work on reducing our footprint in three ways: as activists, by helping push science-based legislation and decision-making through the Reduction Roadmap; through research, by participating in projects that expand knowledge and develop new tools; and through architecture, by integrating the potential for reduced environmental impact into our design process with our clients.

We enable informed decision-making. Balancing your needs, scope, and local conditions, our specialists help you identify where and how to reduce climate and biodiversity impacts guided by climate science.

The Butterfly Framework

Based on climate science, CEBRA uses the Butterfly Framework to guide your environmental strategy, with a focus on two interconnected priorities:

Climate Stability – Reducing CO2-equivalent emissions

Functioning Ecosystems – Reversing biodiversity loss and supporting land restoration

Four project-specific approaches

The dual Butterfly Framework enables us to address both carbon reduction and nature regeneration, informed by the research-based report ‘Beyond the Roadmap’ by the Reduction Roadmap initiative. Guided by these insights, we have defined four strategic project-specific actions that support your team in making informed decisions on footprint:

Climate stability impact assessment

We measure the lifetime carbon emissions of your project using Real-Time LCA. Based on the results, we explore optimisation and propose low-carbon design solutions and material choices for your team.

Functioning ecosystem impact assessment

We are co-developing tools to assess a project’s lifetime biodiversity impact and inform strategies for both reduction and potential regeneration.

Guided by validated data and research, we aim to assess the climate-nature interdependencies and help you understand how different design and planning choices affect the footprint across the project scope.

Potential for refurbishment and adaptive reuse

Within your team’s scope, we assess the design potential of preservation, refurbishment, and repurposing of the built environment, adding compelling chapters to architectural heritage. Based on this, we can provide reuse, circular, and recycling strategies for materials to reduce the extraction of virgin resources.

Supporting longevity

Based on your team’s ambitions, we aim to design bold, beautiful, and poetic architecture that owners and users alike will value and care for. Using adaptive strategies and durable materials, we aim to increase the likelihood of a 120+ years lifespan to limit short-term developments and demolition, as well as interference with surrounding nature.

Additional frameworks

In parallel with the Butterfly Framework, we can help define and work towards targets for environmental impact and well-being through additional services, tools, and certifications.

Specialised services

Our specialists can help you define and implement design strategies towards environmental and social targets. Our services include, among others:

Design with biogenic materials such as mass timber and CLT construction

Consultancy in progressive construction methods

Landscape strategies for climate adaptation and SuDS rainwater management

Development and implementation of smart technologies/PropTech

Strategies and implementation for user-involvement, positive social impact, and well-being

Open-source digital tools

Our studio develops, translates and shares open-source tools and knowledge in collaboration with industry specialists and research institutes. Our open-source resources include, among others:

LCA Volume – Volume-based climate impact estimates for early-stage parametric planning, directly in Rhino

The Butterfly Framework – Biodiversity and climate targets aligned with the Planetary Boundaries

Reduction Roadmap – Paris Agreement-aligned climate impact targets for new construction

Certifications and standards

Together with the project team, we provide environmental and social impact documentation within frameworks such as:

EU Taxonomy

Life Cycle Assessment (LCA) and Life Cycle Costing (LCC)

DGNB

Estidama

LEED
