The revised European buildings directive requires new buildings owned by public bodies to meet the zero-emission standard from 2028. The standard will apply to all other new buildings from 2030.
Most of the city of 2030, however, already exists. The central architectural challenge is therefore to transform homes, offices, hotels and public facilities without removing their usefulness or identity.
From certificate to strategy
Effective renovation combines insulation, solar protection, ventilation, efficient technical systems and renewable energy. The objective is to reduce demand before additional equipment is installed.
Renovating without erasing
Historic and occupied buildings require phased solutions. Architecture must preserve valuable proportions, materials and urban character while improving indoor comfort.
Thinking through the full life cycle
Future quality will also depend on maintenance, adaptability and material choices. An efficient building that is difficult to repair can quickly become a new financial burden.
