The Bijloke site in Ghent, steeped in rich history and diverse architecture, presents a unique challenge in the quest for a sustainable future. The diversity in use, ownership and age of the buildings on the site makes energy optimization and fossil-free heating a complex task. Nevertheless, the City of Ghent and Hogeschool Gent joined forces to draw up a well thought-out plan, with special attention to the historical context and heritage value of the buildings.
HISTORICAL CONTEXT AND HERITAGE VALUE
The Bijloke site is a patchwork of historic buildings with varying functions and ages. However, their common weakness lies in limited energy efficiency and significant CO2 emissions from heating. The challenge is to address these flaws without compromising heritage value and preserving the unique historic atmosphere.
INTEGRATION OF RENEWABLE ENERGY SOURCES
A key step in the project is to identify and valorize opportunities to insulate the building envelope without compromising the heritage value and biodiversity of the site. In particular, this involves detailed exploration of the potential for geothermal energy, taking into account the site's rich archaeological history. In addition, suitable locations for air-water heat pumps will be actively sought, with minimal impact on the appearance of the buildings and low acoustic impact on the park environment.
A key aspect of the project includes mapping the various energy sources on the site. These sources are then integrated into three fossil-free concepts. These concepts are subjected to a thorough assessment in both energy and financial terms, with a view to maximum sustainability and cost efficiency.
LONG-TERM VISION AND CONCEPT
The ultimate objective of this study is to establish a long-term vision and concept for the Bijloke site: striving to significantly reduce CO2 emissions, improve indoor comfort, increase renewable energy production, and prepare the buildings for the next 50 years. During this process, a long-term goal is set, with intermediate steps to meet short-term legal obligations such as EPC NR energy label, mandatory PV installations, and renovation obligations.
A crucial aspect of the project is the close cooperation with site owners, managers and users. Joint efforts not only achieve sustainable goals but also meet the needs and obligations of all stakeholders.
The Bijloke site is poised to become an example of how historic sites can evolve into sustainable, energy-efficient spaces without compromising their unique heritage value. This joint effort between the City of Ghent and Ghent University promises not only a brighter future for the site, but also an inspiration for similar projects.

The Parc du Cinquantenaire in Brussels, steeped in centuries of history and architectural diversity, is facing a large-scale renovation. This ambitious undertaking is driven not only by the need for restoration but also by the urgent need to meet climate goals. In this regard, the development of an energy master plan plays a crucial role.
For the Flemish Energy and Climate Agency (VEKA), Ingenium recently completed the study on cost-optimal levels in new construction of non-residential buildings. The conclusions are not only useful for the government but also allow us to provide even faster and more accurate advice to our clients.
To achieve its sustainability goals, the city of Antwerp is fully committed to district heat networks. These heat networks serve as a sustainable solution for heating buildings within the city. However, not every location within Antwerp is suitable for the implementation of such heat networks.
