Extensive green roofs

An extensive green roof consists of a thin layer of vegetation and a large portion of substrate. It is relatively light, easy to install and requires little maintenance.

Intensive green roofs

An intensive green roof is a roof vegetation consisting of a deeper substrate layer and a wide variety of plants. This requires more maintenance and irrigation than an extensive green roof.

Advantages of green roofs

01.
Good for the environment

Green roofs help reduce the urban heat island effect, improve air quality, and decrease greenhouse gas emissions.

02.
Rainwater retention

It reduces water runoff and helps retain rainwater that can be used for irrigation.

03.
Better solar panel efficiency

The efficiency of solar panels on a green roof will increase by 6 to 24%.

04.
Air-Purifying

A green roof of 300m² captures 1 ton of particulate matter.

05.
Financial value rises

A green roof enhances property values and mitigates the carbon footprint.

06.
Increased roof life

A green roof provides protection against UV radiation and extreme temperatures.

The green roof as an air enhancer

The green roof as an air enhancer

We all know some of the benefits of green roofs: they help buffer rainwater, improve aesthetics, thermal and acoustic insulation of the roof, create additional useful space and contribute to increased biodiversity. Several independent studies now also show that green roofs improve air quality and thus also play a role in slowing climate change.

PIR insulation is not suitable for intensive green roofs

Some cities and towns mandate the installation of extensive green roofs on new flat roofs. By doing so, they aim to provide a temporary water buffer on the roofs that helps prevent overloading the sewer system during heavy rainfall. Although the other benefits of an extensive green roof, such as better thermal and acoustic insulation, increased biodiversity and better protection of the roof waterproofing are also nice to have. Such benefits are not always felt directly by the client or user.
How to thoughtfully manage water harvesting on a blue roof?

How to thoughtfully manage water harvesting on a blue roof?

A blue roof surpasses a green roof in buffering capacity, acting as a harvesting system on the roof. As a designer, you can achieve multiple goals at once: saving valuable ground-level space and avoiding additional costs for constructing buffer basins or tanks. An additional benefit is the reduction of pressure on the sewer system during heavy rainfall.
