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.

The buildings within Cinquantenaire Park are not only different in age and typology, but they also vary widely in their indoor climate requirements. Nevertheless, they share a common problem: limited energy efficiency and significant CO2 emissions due to current heating methods.

Energetic optimization

An in-depth study took place in collaboration with SUMProject SUMResearch and Study Agency Daidalos. The goal? To identify opportunities for improving energy efficiency and fossil-free heating, with particular attention to the historical context and heritage value of the site.

A focus of the study was to insulate the building envelope without compromising the heritage value. At the same time, increased climate requirements of the museum and the expected increase in visitors after the renovation were taken into account.

The study took a deep dive into the potential of collective geothermal energy as a potential economy of scale for efficiency. Detailed research also focused on locations for air-water heat pumps to minimize visual and acoustic impacts. Various energy production options were integrated into three fossil-free concepts.

Energetic and Financial Evaluation

The resulting fossil-free concepts were subjected to careful evaluation in both energy and financial terms. A well-considered preferred scenario emerged as a blueprint for optimizing the buildings energetically during the planned renovation, thus meeting the Brussels Region's climate targets.

The study establishes a long-term vision and concept to reduce the site's CO2 emissions, improve the indoor climate for exhibiting masterpieces, increase renewable energy production, and prepare the buildings for the next 50 years.

An essential condition for the chosen scenario is the possibility of phased implementation. This is necessary given the size of the site and the lengthy renovation period. Involving owners, managers, and various users at the site is an integral part of this collaborative effort to meet legal requirements.

In the interplay of historic splendor and a sustainable future, Jubilee Park lays the groundwork for a restored, energy-efficient environment that will stand the test of time.
