Case studies

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.

A residential building in Zaragoza that applies the Passivhaus standard as a strategic prototype to generalise nearly zero-energy consumption in real estate development.

A tertiary complex that optimises orientation, envelope design and solar radiation control to reduce energy demand in an office environment in Madrid.

A contemporary library that combines energy performance, efficient use of water resources and spatial quality in a new-generation public facility.

Intervention on existing buildings in Paris that combines reuse, urban energy systems, and hybrid ventilation, with a primary energy consumption of 55.3 kWhep/m²·year.
