Get building designs. Holistically optimized with AI-driven analyses.

Based on initial architectural designs (massing models/floor plans) and your goals, Metabuild generates the best design solutions – considering a huge range of options for the building envelope, HVAC and energy supply.

About this service

 

  • Required input data
    • Floor plans/massing models and planning details (heating, building envelope, etc.)
    • Location
    • Type of use
    • Optional: assumptions (e.g. occupancy plans, target values, etc.)
  • The results

    You will receive the simulation results in an easy-to-understand PDF report with a presentation of your results by our experts.

    This will provide you with the most suitable design solutions in comparison to other design solutions. The generated design solution is a specific combination of all design options and contains precise technical specifications (window-to-wall ratios per façades, structure and building envelope, heating, ventilation, air conditioning, lighting, energy generation and water systems.

    In addition, all evaluations are automatically assessed in detail in terms of economic efficiency, comfort and sustainability.

  • This is how design solutions are generated

    This service is applying a dynamic optimization process with more than 4,000 automated year-round simulations for your building. Metabuild automatically generates design scenarios that are then simulated, evaluated and improved.

    In this way, technically and economically optimal building designs are determined on a data-analytical basis during a server run. For each simulation, Metabuild takes into account the dynamic interaction of all parameters, including architecture, materials, building services, weather data, costs, comfort and sustainability.

     

     

  • About Metabuild's AI

    In artificial intelligence, an evolutionary algorithm is a subset of evolutionary computation. Evolutionary algorithms use mechanisms inspired by biological evolution, such as reproduction, mutation, recombination, and selection for complex optimization tasks.

    Metabuild’s evolutionary algorithm was tailor-made to fit the needs of BIM and building simulation. Its unique features allowed us to create the first platform that connects evolutionary multi-objective optimization with the power of building simulation and cloud computing.

    Backed by science: Our software was developed by leading scientists in the field of building simulation and optimization. Studies on the impact of our technology have been published in leading peer-reviewed journals. Through Metabuild’s partnerships with TU-Berlin and NTNU Trondheim we’re constantly improving our software.
