CAALA

Core Features

CAALA’s methodology is built around parametric life-cycle analysis: a method that links all relevant design and operation parameters so that any change in geometry, materials or building services immediately shows its effect on environmental and economic performance over the full life cycle. This approach allows LCA to be used in early design while remaining robust enough for certification and reporting, for both new projects and existing portfolios. Building on this workflow, CAALA’s software environment offers several concrete capabilities:

• Model-based lifecycle metrics - CAALA calculates operational and embodied CO₂ emissions, energy demand and life-cycle costs for each design variant or existing asset, using geometric models and parameter inputs rather than accounting spend data.

• Variant and scenario comparison - The software supports parallel variants and parametric studies, so planners can compare multiple design or refurbishment options in real time and understand the trade-offs between emissions, energy and costs.

• Broad CAD/BIM connectivity - CAALA connects to SketchUp and Rhino via plug-ins and imports models from Revit, Allplan and Archicad through IFC and gbXML, while existing buildings can be generated from OpenStreetMap data via Mapbox.

• Portfolio and renovation planning - Beyond single projects, the Portfolio Manager aggregates results to identify cost-efficient retrofit measures and decarbonisation pathways across portfolios, including quick assessments of refurbishment scenarios.

• Certification and policy alignment - CAALA’s LCA results can be used to support building certifications and sustainability reporting; the knowledge base includes guidance on QNG compliance and EU Taxonomy use cases.

• Flexible exports and reporting - Results and model data can be exported for reports, certification submissions or further processing in other tools, supported by dashboards and a CO₂-performance report tailored to different stakeholder needs.

Closing Insights

CAALA was founded in 2016 in Munich by Philipp and Alexander Hollberg to bring research on parametric life-cycle assessment into everyday planning practice. Alexander’s doctoral work at Bauhaus University Weimar developed the CAALA method (Computer Aided Architectural Life-cycle Assessment) and was recognised with the Deutscher Bauforschungs-Nachwuchspreis and several innovation awards for its structured, practitioner-oriented approach to integrating LCA into the design process. Philipp’s background in energy and climate-innovation programmes at EIT InnoEnergy and Climate-KIC helped shape CAALA as a SaaS platform that gives planners real-time feedback on environmental and economic performance, even without deep prior expertise in energy modelling.

In practice, this research-driven foundation has made CAALA a tool used both in commercial projects and in teaching and research at institutions such as Bauhaus University Weimar, ETH Zurich and RWTH Aachen. Real-estate companies including EnBW, Sonar Real Estate, Instone Real Estate and GLS Bank cite CAALA for portfolio decarbonisation decisions and investment analysis, while engineering and construction groups such as Köster integrate it into their service offerings.

For organisations that want to embed life cycle thinking into everyday design and asset management, CAALA offers a structured way to move from ad-hoc calculations to continuous, portfolio-wide analysis, backed by in-house advisory services and a dedicated academy for training project teams.
