The design seamlessly integrates with the modernist architecture of the Tilburg University Campus. Its circular ambitions are reflected in the renewable nature of its wooden construction, walls, floors, stairs, frames, and finishes. We implemented a unique dry construction system, utilizing wooden ribbed floors—CTL floors reinforced with beams—that enable large free spans meeting the high acoustic requirements necessary for the program. By proposing a wooden structure in our vision for the tender, we motivated the client to take the next step in sustainable educational buildings. Together with Tilburg University, we further elevated the ambitions during the design process to achieve a maximally circular and energy-neutral design.
The complex is situated on the forested campus of Tilburg University. The Portuguese natural stone facade directly references the iconic 1962 Cobbenhagen Building by Jos Bedaux. The natural stone, with its long lifespan and ability to be disassembled, confirms the circular ambitions. The stony volume harmonizes with its surrounding, forming an intriguing contrast with the lush wooded environment.
We took the Cobbenhagen Building as a starting point for spatial qualities but brought the design into the 21st century by opting for a palette of natural, circular materials such as wood, terrazzo, and plasterwork. Our design aligns with Bedaux's architecture with muschelkalk stone facades and rhythmic window divisions. In doing so, we emphasize a strong connection with the natural environment.
Marga Klompé Building is designed with the latest insights in sustainability based on the Trias Energetica principle, including very low energy consumption and smart use of natural resources. A well-insulated building envelope does the rest for a passive contribution to low energy usage. We chose a special material: the insulation partly consists of recycled denim jeans. Textile waste that would otherwise be incinerated is now used to create cotton insulation. It is sustainable and has proven to be an excellent way to improve the building's acoustic comfort. The Marga Klompé Building can proudly boast a BREEAM Outstanding certificate and achieves nearly energy neutrality. It also has an impressive circular assessment with an MPG score of 0.5, a BCI score of 0.61, and an MCI score of 72%.
Marga Klompé Building accommodates a foyer, 1 auditorium, 13 lecture halls, and self-study spaces for approximately 1,000 students. Its distinctive architecture pays homage to the monumental Cobbenhagen Building on the campus while also serving as a model for the highly sustainable ambitions of university campuses in Europe.
The design maximizes the number of PV panels and integrates energy-efficient installations. Ventilation and lighting feature smart control systems that adapt to actual demand. Heating and cooling are provided by an efficient ground storage system with a heat pump. Despite the strong emphasis on energy efficiency, the indoor climate meets Fresh Schools Class A standards.
Thanks to the thoughtful design of the building, the use of climate installations can be minimized. Stringent requirements for air quality have led to the integration of ventilation and climate systems. Furthermore, the atrium has been cleverly utilized to harness return ventilation. This has resulted in a significant reduction in the required ductwork, contributing to an impressive circular assessment. Thanks to close collaboration between architect, structural engineer, and installation consultant, the Marga Klompé Building has been realized, with innovative solutions leading to an optimal result. The lecture halls have impressive spans of 9.2 meters, achieved with CLT ribbed floors. This enabled us to meet requirements for vibrations and acoustic comfort.
"From the outset, we knew we had the right partner. The decision for a wooden construction was surprising but fitting with our sustainability goals. Despite challenges, the ideas remained intact, allowing us to follow a clear course. The process was characterized by passion, dedication, and communication. This has led to a unique project that strengthens the identity of our environment." - Richard Antens (Project Manager, Tilburg University)
