Engie's headquarters project showcases a comprehensive renovation of an energy-inefficient and poorly designed building from the 1980s, transforming it into a contemporary property that is LEED Platinum-certified. This renovation supports the revitalization of Milan's Bicocca district. The project fundamentally re-imagined the building's architecture, creating a lighter, more articulated form with new rooftop terraces offering panoramic views.
Key improvements addressed obsolescence and energy inefficiency, creating a dynamic workspace integrated with the revitalized neighborhood and connected to the underground station. The building’s orientation was redesigned for enhanced visibility, and the ground floor reception was expanded to showcase the adjacent green space.
A high-performance insulated glass façade maximizes natural light and external connectivity, featuring a double-glazed curtain wall with aluminum shading fins for exceptional insulation (0.7 W/m²K). Sleek aluminum accents add a refined aesthetic, while a striking glass and metal entrance pavilion with a protective canopy welcomes visitors.
The project’s LEED Platinum certification underscores its commitment to sustainability, particularly in water conservation. The landscape includes 5,100 square meters of green spaces filled with drought-resistant plants, supported by an 85 cubic meter rainwater tank for irrigation.
Sustainable strategies
Low-carbon strategies were central to the renovation, focusing on enhancing energy performance and minimizing environmental impact. Radiant ceiling panels efficiently regulate indoor temperatures, significantly lowering heating and cooling demands. The roof is equipped with photovoltaic panels, generating renewable energy. A smart Building Management System (BMS) optimizes functions such as lighting, HVAC, alarm management, and maintenance. Interior office spaces were redesigned for energy efficiency and soundproofing, enhancing the workspace environment.
A new porter's lodge, constructed from transparent glass and press-bent sheet metal, integrates with the building's perimeter. The floor-to-ceiling insulated double-glazing façade maximizes visual connection between the workplace and the external environment. Horizontal and vertical anodized aluminum elements subtly break up the building's scale, enhancing the interplay of light.
The Bicocca district, a former industrial site, has been transformed into a vibrant hub anchored by the University of Milan, featuring cultural and commercial landmarks. The recently inaugurated metro line enhances connectivity. The comprehensive redesign and technological modernization of ENGIE HQ align with this district's revitalization, enhancing its attractiveness for businesses.
Designed for adaptability, the project features modular workspaces and open layouts supporting future functional changes. The building's robust structure accommodates programmatic shifts, ensuring longevity and minimizing future demolition. Its architectural merit, smart working spaces, environmental sensitivity, and contextual awareness contribute significantly to the industrial area's revitalization.
