Green Roof Benefits

Overlake Hospital Medical Pavilion Rooftop

Increases the feeling of well-being

Living and working in a green environment has a positive effect on the well-being of people. Greenery offers relaxation and reduces stress.  

Offers healing environment

Greenery encourages faster recovery for patients, resulting in a shorter hospital stay. A persons tolerance of pain is higher  in a green environment. This is also known as a ‘healing environment’.

A green roof protects the roofing material from external influences such as the sun, rain, wind and temperature fluctuations and doubles or triples the life span of the roof to up to 60 years or even longer. You will recoup the investment in your green roof within 8 to 21 years.

Plants absorb sunlight, 50% is absorbed and 30% reflected; so green roofs help to create a cooler and more pleasant climate. For the indoor climate this means that the air conditioning doesn't have to work so hard, which in turn means energy savings. And this too has an extra positive effect on the climate in the immediate vicinity of your building and on the temperature in the city. Overall, it means a 3°C temperature reduction in the city.

The Sedums, herbs, grasses or host plants that are included in a green roof promote the habitat of birds, butterflies and insects, especially in the city environment which is mainly concrete and asphalt.

A green roof absorbs rain water by the water buffering in the plants, substrate and drainage layer. This delays the discharge of rainwater to the sewage system, purifies the rainwater, and water also evaporates through the plants. This all helps to stabilize the groundwater level, reduces the peak load on the sewage system and reduces the risk of flooding.

The natural and sustainable appearance, combined with a reduction in energy costs and extension of the life span of your roof, means an increase in value of your property.
