Building Envelope Engineering
The building envelope is far more than an exterior skin: it is a strategic interface between indoors and outdoors, directly influencing both energy performance and occupant comfort.
Climate-responsive envelope design
Our approach to building envelope engineering is based on analysing climatic conditions, functional requirements, and architectural ambitions. We design tailored solutions that integrate thermal insulation, solar control, natural ventilation, and daylight optimisation.
Innovative façades and building skins
Our engineers work closely with design teams to develop innovative systems, from breathable envelopes and advanced double-skin façades to building skins incorporating photovoltaic technologies. Each envelope becomes a driver of overall building performance, contributing to structures that are energy-efficient, comfortable, and adapted to their environment.

Our projects
Cities and buildings are at the heart of the 21st-century sustainability challenges. In Luxembourg, Sweco designs urban spaces and buildings that are sustainable, inclusive, and smart. Our multidisciplinary teams combine expertise in architecture, engineering, and environment to develop integrated solutions: resilient neighborhoods, low-energy buildings, and pleasant living spaces. Through digitalisation, circular materials, and biodiversity integration, we create environments ready for tomorrow.
