Multifunctional rooftop for Rotterdam University

A roof that does more than protect

Roofs are playing an increasingly important role in making cities more sustainable. While traditional roofs mainly provide protection from the elements, this rooftop serves multiple purposes at once. It combines stormwater retention, biodiversity, cooling and renewable energy generation in one integrated solution.

For Rotterdam University of Applied Sciences, the project represented an important step towards creating a future-proof campus. It demonstrates how existing buildings can contribute to the sustainability ambitions of both educational institutions and cities.

Stormwater management for a climate-resilient city

Rotterdam is increasingly experiencing intense rainfall events as a result of climate change. These downpours can put pressure on the city’s drainage system and increase the risk of flooding. The green roof helps mitigate these challenges by temporarily storing rainwater and releasing it gradually over time.

With a water retention capacity of 25 litres per square metre, the roof can buffer nearly 80,000 litres of rainwater. This reduces pressure on the urban drainage network and contributes to a more climate-resilient environment.

Green energy above the classroom

One of the most distinctive aspects of the project is the combination of rooftop greenery and solar energy generation. A total of 810 solar panels were installed across the Museumpark and Academieplein locations. The electricity generated is used within the educational buildings and supports the university’s sustainability goals.

For thousands of students and staff members, renewable energy has become a visible part of everyday campus life. The solar panels provide clean electricity for laptops, mobile phones and other facilities throughout the university.

A healthier learning environment

In addition to water management and energy generation, the green roof provides several other benefits. The Sedum roof helps reduce rooftop temperatures during warm periods and contribute to a more comfortable indoor climate. The vegetation also improves air quality by absorbing CO₂ and releasing oxygen.

The appearance of the buildings has changed significantly as well. Instead of looking out over a conventional grey roof, students and staff now enjoy views of a vibrant green landscape that remains attractive throughout the year.

Leading the way in sustainability

With approximately 40,000 students and 4,000 employees, Rotterdam University of Applied Sciences has a considerable environmental footprint. The institution therefore actively invests in sustainable solutions that contribute to Rotterdam’s climate ambitions. The city aims to become climate neutral by 2050.

The installation of these multifunctional rooftops represents an important step towards achieving that goal. The project shows how educational institutions can lead by example and make sustainability tangible for future generations.

The power of a Solargreen Roof

Combining a green roof with solar panels makes optimal use of available rooftop space. The Sedum roof protects the roof membrane from extreme temperatures and creates a cooler microclimate around the solar panels. As a result, the panels can operate more efficiently, as solar modules generally perform better at lower temperatures.

At the same time, the green roof delivers additional benefits such as stormwater retention, biodiversity enhancement and urban cooling. By combining renewable energy generation with climate adaptation in a single rooftop solution, Rotterdam University of Applied Sciences demonstrates how buildings can actively contribute to a more sustainable and future-proof city.
