Green as the foundation for healthy urban sports

In the Utrecht district of Kanaleneiland, an outdated gym hall was sustainably renovated into a future-proof sports facility. With a SemperGreenwall Outdoor, the building gained a green identity that naturally connects health, physical activity and urban greening.

Healthy sports environment

Greenery contributes to fresh air and a pleasant environment for exercise and sports.

Green in the city

Vertical greening makes an impact, especially in densely built neighbourhoods.

Future-proof renovation

The green façade gives an existing building a new perspective and appearance.

A fresh impulse for a familiar place

The gym hall in Kanaleneiland has been a familiar place for sports, play and education in the neighbourhood for decades. Commissioned by the Municipality of Utrecht, the forty-year-old building underwent a thorough and sustainable renovation in 2014. The goal was clear: to once again make the gym a place that encourages movement, with attention to health and long-term value. By adding a SemperGreenwall Outdoor to the exterior façade, the building not only gained a completely new look, but also a clear message. This is a sports facility that embraces health, both literally and figuratively.

Exercising in a healthy environment

A healthy sports environment goes beyond good indoor facilities alone. The surroundings in which people exercise also influence how they feel. Greenery reduces stress, improves air quality and creates a more pleasant microclimate. The SemperGreenwall Outdoor contributes to cleaner air around the gym hall and turns the building into a fresh, inviting place to move. For children, young people and sports clubs, the gym feels less closed and more connected to the outdoors.

Gym halls play an important role within education. They are the places where children learn to move, cooperate and push their limits. By greening this gym hall, health becomes a visible part of that lesson, not only inside but also outside. The building shows that physical activity, wellbeing and a healthy living environment are inseparably connected. In this way, the green façade supports the broader ambition to embed health structurally in education and daily routines.

Green in a densely built neighbourhood

Kanaleneiland is an urban district where space is scarce and buildings dominate the streetscape. This is exactly where vertical greening makes a difference. By using the façade, additional greenery is created without sacrificing valuable square metres. The green wall softens the streetscape, brings nature back into the neighbourhood and contributes to climate adaptation through cooling and water buffering. A relatively simple intervention with a major impact on the quality of the living environment.

The design of the green façade, created by Frowijn de Roos Architects, fits seamlessly with the sustainable renovation of the building. The SemperGreenwall turns the gym hall into a recognisable and future-proof sports facility. The project demonstrates how existing public buildings can be upgraded with greenery, not by building new, but by renewing intelligently. This way, the gym hall remains a healthy place for sports and social interaction, now and in the future.

Green as a natural air filter

Plants play an important role in improving air quality, especially in an urban environment. The vegetation in the SemperGreenwall captures fine dust, binds harmful substances and contributes to oxygen production. Around a sports facility, where children and young people are physically active, clean air is especially important. The green façade helps create a fresher and healthier environment, both directly around the building and throughout the neighbourhood.

Plant mixes tailored to location and climate

For outdoor green façades, Sempergreen works with a variety of carefully composed plant mixes. These are tailored to factors such as sun orientation, wind exposure and the local climate. Sun-exposed façades require different species than shaded locations. Thanks to this smart plant selection, the façade remains vital, green and balanced throughout the year. The result is a façade that functions technically and visually fits its surroundings, while subtly changing with the seasons.
