Energy-intensive building

This wooden passive residence project is exemplary in terms of both its urban integration and its environmental and energy performance. Indeed, the project must respond appropriately to the challenge of addressing the future residence, an important symbolic issue, not only for the Housing Fund, but also for the municipality of Steinfort. The expression of the building is sober and contemporary, the volumetry integrates harmoniously into the profile of the Arlon road. Most of the building, apartments and roofs are constructed of wood, while the basement and vertical walkways are constructed of concrete. The building is designed to meet the Passive Energy Performance Class (AAA) according to the Grand Ducal Regulations and to obtain the international certification label of the PassivHaus Institute Darmstadt. In summary, the present passive residence project has been developed taking into account all relevant stakeholders and aims to propose a consensual solution in the spirit of sustainable development, social responsibility and respect for the environment.

Owner approach of sustainability

- The objective was to conceptualize a sustainable and passive building. - The specificity of the project is that the basement that was built in concrete as well as the common circulations are not in the thermal envelope.

Architectural description

The present passive residence project has therefore been conceived in the spirit of sustainable development, social responsibility and respect for the environment
