Cities are vulnerable to the effects of climate change. Extreme weather conditions, such as very hot summers and increasingly strong storms, cause floods, heat problems and poor air quality. Sustainable spatial planning, such as green roofs, play an important role in climate-proof construction. The city of the future is definitely a green city.

A climate-friendly city starts on your roof! That’s why ECCOsedum tiles are extremely climate-friendly.

In comparison, conventional sedum slabs are prone to drought and will soon have to be watered during dry periods because the substrate thickness is limited, while ECCOsedum slabs contain more substrate and are therefore more resistant to climate change. Unlike most other sedum slabs on the market, ECCOsedum slabs are slightly heavier. They weigh 75 to 80 kg/m² when fully saturated with water. Other similar lightweight sedum slabs weigh only 50 to 55 kg/m². The extra weight is provided by the higher water storage capacity of these ECCOsedum slabs. Thanks to this, it will help to provide a cooling effect in summer.

To reduce the increasingly frequent disruptions caused by heavy rainfall, it is becoming increasingly important to apply water retention to roofs. Studies show that green roofs can store at least 50% of precipitation in the drainage layer, substrate and vegetation.

Air and water purification

Green roof plants filter particles from the air and convert CO2 into oxygen. In this way, green roofs contribute to a better environment by purifying the air. Green roofs also provide water purification: since polluted precipitation first flows through the green roof, some of the pollution is filtered out before it reaches waterways.

Surfaces with plants warm up more slowly and retain less heat. In addition, plants evaporate water, causing the air to cool. This creates a cooler and more pleasant urban climate.

In addition to thermal insulation, a green roof also has a sound-absorbing effect. The combination of substrate, plants and entrained air in a green roof system provides good sound insulation. Sound waves are collected and reflected. The substrate blocks lower sound waves, while plants block higher frequencies. Consider the noise from aircraft and traffic, as well as heavy rain and hail. Green roofs provide a 3 dB reduction in sound reflection and up to 8 dB of sound insulation. This reduction may not seem like much, but to the human ear, a 10 dB reduction in noise is a 50% reduction. Sound insulation depends on the thickness of the green roof structure.

The efficiency of solar panels on a green roof is up to 16% higher than the efficiency of solar panels on a conventional roof.

Solar panels are most efficient at low ambient temperatures. For example, temperatures on a black/bitumen roof can reach around 60 to 70°C, compared to only 35°C on a green roof. This significantly increases the efficiency of the solar panels. In addition, lower temperatures also reduce wear on the solar panels, so they last longer. In fact, the roof covering lasts about 2 to 3 times longer. Biodiversity is also improved by solar panels, as other plants will establish themselves in the shaded areas under the panels.

A green roof primarily has a thermal regulation effect. This effect is greatest in summer. With traditional roofing, large fluctuations in indoor temperatures can occur. In summer, the building heats up because the grey roof absorbs the sun's heat. When a green roof is installed, direct sunlight is reflected by the vegetation instead of being absorbed. In addition, the moisture in the vegetation evaporates, providing additional cooling. This together ensures that the temperature in the building remains lower and you can save on energy costs for air conditioning.

The view of greenery has a positive effect on a person's mood and, consequently, on a person's physical health. In addition, the vegetation changes depending on the seasons, which provides a pleasant variety of views.

A green roof lasts longer than a conventional roof covering (up to twice as long compared to a flat roof with a bitumen coating). The presence of a layer structure protects the roof covering against: UV radiation, heating of the roof surface, freezing and temperature fluctuations, uneven heating of different roof layers and mechanical damage.
