A fire broke out in late October 2024 at the Treurenberg building in Brussels, the city’s first net-zero energy structure. The fire, likely caused by the building-integrated photovoltaic (BIPV) panels on the facade, prompted an evacuation. Fortunately, no injuries were reported. Authorities are still investigating the exact cause of the fire, and insurance assessments are underway. Preliminary damage estimates suggest a loss of around $1 million.

In late October 2024, a fire broke out at the Treurenberg building in Brussels, the city’s first net-zero energy structure. The building, which is equipped with building-integrated photovoltaic (BIPV) panels, is a flagship example of sustainable architecture. The fire occurred on the upper facade, likely sparked by the solar panels, according to Brussels’ fire brigade.

The Treurenberg building, commissioned by the European Commission in 2016 and designed by Assar Architects, is a prominent example of eco-friendly design. AXA Real Estate Investment Managers owns the building, while VK architects+engineers participated in its construction. The fire led to an immediate evacuation of the building, and fortunately, no injuries were reported. The fire brigade quickly cut off the inverter to safely manage the situation and partially dismantled the panels to reach the insulation beneath.

The exact cause of the fire is still under investigation, and the insurance report is awaited. Early estimates indicate that the damage caused by the fire could be as high as $1 million, which includes potential damage to the solar panels and the building’s infrastructure.

This incident highlights the importance of early fire detection, especially in buildings with integrated solar systems. The Treurenberg building’s use of BIPV panels shows how renewable energy solutions can be integrated into architecture, but it also underscores the risks involved when such systems are not adequately monitored.

Planck Vision Systeme offers advanced thermal imaging solutions that can provide constant monitoring for potential fire hazards. Our TRX600 robotic system and thermal imaging cameras can detect abnormal heat signatures before they escalate into major fires. This proactive approach helps to prevent costly damage and protects both human lives and valuable assets.
