Using digital tools as a catalyst for better and more sustainable design.

This blog represents our ongoing findings on vision and reality about utilizing digital tools in the architectural and urban design field.
We believe that in sustainable design the really significant decisions happen in the early stages. Hence the focus of this blog is on green building design tools for architects and planners that are easy to learn and apply.  To be successful in the architectural community these tools shall be interactive and provide visually comprehensible output. They shall enable the designer to make informed decisions based on simulation results and support clear client communication.

  1. Hi,

    Here is a story I thought you might find interesting:

    There are islands of plastic debris the size of Texas floating around in the Pacific and other oceans. Home appliance maker, Electrolux, is going to turn them into vacuum cleaners.

    To inspire people into solving the issue and bring awareness to the situation, Electrolux will go to the scene of the crime and gather plastic from the plastic islands, and from the material gathered, turn it into vacuum cleaners.

    The global initiative is called “Vac from the Sea” and aims to bring attention to the issue of plastic pollution and at the same time combat the scarcity of recycled plastics needed for making sustainable home appliances

  2. Hi,

    I love your blog!

    I work with Valentin Software. We develop and distribute solar design software for both PV and Solar Thermal systems. The company was founded 20 years ago in Berlin, Germany.
    Why don’t you have a look at our web site?
    You might find our software products interesting, especially because you guys have a German background, too.

    Best regards,

  3. Hello,

    New inovative software pvPlanner, for solar radiation site analysis and yield assessment available now at:

    This tool is perfect alternative to PVGIS, which is free but in other hand not so accurate and reliable.

    With pleasure we can say that our software works with the best solar data presently available on market (recent study of University of Geneva in collaboration with International Energy Agency; February 2011)
