15 Interesting Green Roofs From Around the World

Green roofs, walls, and vertical gardens provide crowded cities with green areas, spaces for recreation and assist in the reduction of the greenhouse island effect. Research shows that green roofs and walls can drop the temperature of cities by 1-2 degrees Celsius.

Green roofs benefit not only the buildings they sit upon but also lower temperature levels in cities and create soothing visuals for city-dwellers.

These wonderful roofs and walls also benefit the interior of buildings. A well designed and maintained green roof can lower the inside temperature of a building by up to 1-degree and offset the cost of heating and cooling.

In addition to being a smart economic choice, green walls provide high levels of psychological value to city dwellers. Being either visually or physically close to green areas has a calming effect on many people.

Green roofs also absorb rainwater and provide much-needed habitats for urban dwelling animals. The benefits of green walls are endless and the idea isn’t new. Evidence of green roofs goes back centuries as a way of keeping buildings warm in winter and cool in summer.

We have collected 15 astonishing green roofs to show them off at every scale and purpose.

1. The Nanyang Technological University in Singapore rocks two 45-degree green roofs

The Nanyang Technological University hosts one of the most iconic lawned grass roofs in the world. The building of the School of Art Design and Media features two swooping roofs that slope to an impressive 45-degree angle.

Each roof is covered in lawn which not only contributes to the buildings' low energy use but provides an outdoor communal space. The green roof is composed of a combination of two kinds of grass, Zoysia matrella, and Ophiopogon.

Under this grass is four layers of substrate. Volcanic rocks and pumice provide depth while a layer of washed sand locks in the root system of the grass. The roof has a moisture retention mat. The grass is watered via an automatic sprinkler system that uses harvested rainwater.

2. The ACROS Fukuoka Prefectural International Hall of Japan, 15 terraces of Greenery

This green roof consists of 100,000-square meters of greenery stepped over 15 terraces that form the roof of the ACROS Fukuoka Prefectural International Hall. The impressive park was designed by renowned green architect Emilio Ambasz in 1995.

Controversially the government-owned building was proposed to be built on Fukuoka City's last remaining green site. Argentinian Ambasz was able to secure the contract for the design of the building by demonstrating he could provide both a park and a building.

The building and its greenery is still a leader in demonstrating the way green roofs can be used to both increases the economic viability of buildings by reducing heating and cooling costs as well providing necessary green space in dense urban environments.

3. City Hall, Chicago: Home to 20,000 plants and over 150 animal species

The green roof on the City Hall in Chicago started as a way to demonstrate the positive effects green roofs can have on reducing the greenhouse island effect in cities. To lead the way, City Hall planted more than 20,000 plants from over 150 species in a 3,530-meter space.

What is most impressive about this roof garden is that the plants are able to thrive in Chicago’s crazy weather conditions. The city experiences extreme temperature changes from snowy winters to humid summers.

The plants chosen for the rooftop are endemic to the area, meaning they have already adapted to survive in the local climate. Another unusual aspect of the green roof is that it was added to the building after completion. The roof garden has a very slim and lightweight profile as not to overload the existing building's structure.
