A high‑efficiency building that combines reversible heat pumps, self‑consumption photovoltaics, and an optimised envelope with natural insulation and a modular timber structure to achieve outstanding energy performance.
The LSC Contern building constitutes a notable example of the coherent integration of energy efficiency strategies in a newly constructed office project. Its A-energy rating is achieved through a balanced combination of high‑performance technical systems and architectural decisions aimed at reducing energy demand from the design stage. The main climate control system is based on reversible heat pumps, a technically robust solution suitable for Luxembourg’s temperate climate, allowing optimisation of both thermal production and electricity consumption.
The building also incorporates photovoltaic installations for self‑consumption, which directly contribute to covering part of the energy demand and reducing dependence on the grid. This integration between renewable generation and the thermal system forms one of the pillars of the project’s overall energy performance.
The thermal envelope relies on materials and construction solutions with strong energy efficiency, including sheep’s wool insulation and a modular timber structure, which improve thermal behaviour and align with the circularity philosophy adopted for the building. Likewise, the decision to avoid false ceilings and keep materials exposed enhances thermal inertia and reduces the need for additional elements.
