MEP building services engineering
Saint-Étienne, AURA

In Saint-Étienne, MEP design applies first and foremost to existing buildings, with networks and boiler plant that are often oversized, inherited from a period when the envelope was far more heat-losing than after refurbishment. Resizing after insulation is the technical point most frequently overlooked on these projects, and the one that most degrades actual efficiency. The presence of an urban district heating network also alters the choice of energy production for schemes that can be connected. We work across HVAC, plumbing and high-current/low-current electrical (power and data), from diagnosis through to works supervision.

In Saint-Étienne, the sizing of the HVAC, plumbing and electrical technical packages determines summer comfort, RE2020 compliance and operating cost. Integrated MEP design, coordinated with equipment acoustics and the BMS, avoids costly rework on site.
