The integration of renewable energy sources, particularly solar power, is becoming essential in sustainable construction. As competition intensifies, achieving high energy performance certifications is now critical for modern buildings, both from an economic and a regulatory perspective.
In the construction sector, the shift towards sustainable practices has become a necessity, driven by growing demand for more environmentally responsible buildings. “Real estate funds, in particular, are increasingly integrating solar panels systematically into new developments in order to meet energy performance requirements such as BREEAM or DGNB certifications,” explains François Neu, General Manager of Enerdeal Luxembourg and Group CMO.
The importance of solar panels in modern construction
Property developers and industrial companies are facing increasing pressure from shareholders and customers to equip new buildings with solar panels.
“This trend is driven by the need to achieve high-energy-performance buildings, making them more attractive from both a marketing and an economic standpoint,” continues François Neu. “A building with a high energy certification is often more competitive, both in terms of operating costs and perceived market value. However, it is important to note that the vast majority of today’s photovoltaic market focuses on existing buildings, which account for approximately 95% of installations, compared with only 5% for new developments.”
This imbalance is partly due to the fact that sustainability requirements are often stricter for new developments managed by real estate funds, while industrial companies remain somewhat less inclined to make these practices a priority.
Photovoltaics and e-mobility: a growing synergy
Another rapidly expanding area is the integration of e-mobility infrastructure, such as photovoltaic carports.
“These installations, which combine solar energy generation with parking facilities, address the growing demand for electric vehicle charging solutions. This type of project is becoming increasingly common, not only in new developments but also as part of upgrades to existing buildings. The visibility and strong visual impact of photovoltaic carports enhance a company’s environmental image while simultaneously addressing practical needs.”

The financial crisis has affected many sectors, including construction. However, the photovoltaic market appears to be following an independent trajectory.
“Although the number of new developments remains relatively limited, existing industrial and commercial buildings represent a major opportunity for solar installations. In some cases, pressure comes directly from customers or shareholders who require the installation of solar panels in order to maintain business relationships or strengthen the company’s image. For example, companies such as Volvo are urging their industrial partners to increase their use of solar energy, with the risk of losing contracts if they fail to do so.”
Despite the limited number of new industrial developments, there are notable examples of companies taking significant sustainability initiatives.
“I can mention Rotarex, which recently signed a contract for the construction of a new manufacturing facility in Bissen. The company decided to cover all rooftops with solar panels and install photovoltaic carports. This decision demonstrates that, even within the industrial sector, there is growing awareness of the importance of integrating renewable energy solutions from the very earliest stages of building design.”
Towards mandatory sustainability
It is becoming increasingly clear that sustainability will not simply be an option in the future but a legal obligation.
In Flanders, for example, new regulations require companies with more than 2,500 m² of roof space and an annual electricity consumption exceeding 1,000 MWh to install solar panels by June 2025, or face recurring financial penalties. Similar legislative developments are underway in France and Germany. These regulations clearly demonstrate the determination to strengthen the integration of renewable energy into both new and existing buildings.
“For developers and industrial companies, failing to anticipate the integration of renewable energy solutions such as solar power is now a serious strategic mistake. Whether to comply with legal requirements, meet customer expectations, or avoid a decline in property value, sustainability has become an essential component of every construction project. Those who fail to plan for solar installations or e-mobility infrastructure risk finding themselves at a disadvantage, both economically and from a regulatory perspective.”

The future of construction depends on the adoption of sustainable practices. Companies must prepare for an environment in which renewable energy will no longer be an option, but an unavoidable necessity.
