Case studies

Green Idea House demonstrates how a comprehensive refurbishment can combine net-positive energy, waste reduction, water savings and community engagement, using design strategies focused on life-cycle thinking and operational performance.

This bank branch in Germany demonstrates how bioclimatic design and a low-tech climate control approach can combine comfort, energy efficiency and a positive annual energy balance in an office building.

Entrepatios Las Carolinas explores an alternative way of developing and inhabiting urban housing, combining high environmental performance, low-carbon construction and a cooperative model that places the community at the centre of the project.

The refurbishment of a 1970s detached house in Germany demonstrates how a strategy focused on reducing energy demand can transform an existing building into a positive energy home.

A logistics facility in Leutkirch, Germany, eliminates mechanical ventilation and uses daylighting and biogas‑based heating to reduce energy use.

The project combines thermal insulation, controlled ventilation and solar generation to balance heating, cooling and electricity needs.

A university research building in Valladolid showcases net‑zero operational carbon through bioclimatic design and exclusive use of renewable energy sources.

The refurbishment of a residential and office building dating from 1982 in Ravne na Koroškem, in Slovenia, is presented as an example of industrialised deep renovation aimed at improving the energy performance of an existing multi-family building.

The new Médecins Sans Frontières headquarters in Geneva combines spatial adaptability, energy efficiency and passive design strategies. The vegetated envelope, solar protection measures and the use of locally sourced timber contribute to its environmental performance.
