Planting within cities is nowadays widely recognized as a way to improve air quality and reduce overall heat, but lack of space and overpriced land makes it difficult to increase the amount of parks and natural space. This is when rooftop gardens come into the picture, and is the reason why they have become more and more popular over recent years, particularly in larger and more developed cities.
Rooftop gardens look good, have a great view, and provide a smart and quick way to enjoy a quiet retreat in the heart of the city. But beyond their decorative benefits, there are many other impressive and important advantages to building rooftop gardens.
Countries such as France, Switzerland, Canada , Japan , Korea, China and Singapore have all passed laws regulating and demanding that all new commercial and residential buildings have at least a partly green rooftop. In Sri Lanka, it is getting widely popular. Incorporating green roofs to buildings is an initiative that has been taken in the recent past.
When you continue reading , you will see the benefits of rooftop gardens, so you can see for yourself how amazing this architectural and environmental initiative is, and why it should be present in every building or home around the globe.
Imagine you’re at work and for your lunch break you decide to leave the office. You take the lift up to the highest floor only to emerge in a beautiful park with incredibly privileged views. Doesn’t sound too bad, does it? Rooftop gardens provide contact with nature in places where that has become a bit of a luxury, such as in big crowded cities.
According to recent studies it has shown that having regular contact with nature and green spaces in urban areas can help to keep you mentally healthy and aid with your overall happiness.
In addition, because of the decreased pollution levels and the increase in water and air quality provided by green rooftops, demands for health care and stress could be reduced.
Less stress levels also means happier and more productive employees, and therefore easier employee recruitment for companies.
2. Improved air quality
Rooftop gardens contribute to the reduction and filtering of polluted air particles and gases, not only through the plants and the photosynthesis process, but also by deposition in the growing space.
Green roofs also help reduce the distribution of dust in the air and the production of smog, which leads to decreasing greenhouse emissions in urban areas.
It is important to note, however, that one green roof in a city may not have a huge effect all on its own, but larger numbers of green roofs in a city will definitely have a noticeably positive impact.
3. Decreased waste
Rooftop gardens could potentially contribute to a decrease in waste, due to helping the materials and technologies used in the building to last longer. This can include the waterproofing membranes used on the concrete roof, and the decreased use of heating, ventilation, and air conditioning systems.
4. Effective use of rainwater
Rain is free water and energy we get from the environment, and rooftop gardens are perfect to make the most of it.
Plants on green roofs use the rain immediately, and sometimes the excess is stored so that it can be used later. After the water is used it is returned to the atmosphere through transpiration and evaporation. Plants in rooftops not only retain rainwater, but also help to moderate its temperature, acting as natural filters for any water that runs off the building. The chances of water run-off, however, is also decreased by rooftop gardening. It will also reduce the impact this may have to the city and the possibility of local flooding.
5. Urban Heat Island (UHI) effect ENERGY control
Probably one of the most impressive and important benefits of rooftop gardens is how they positively affect the Urban Heat Island effect.
The UHI concept is based on the increased temperature levels found in pretty much all urban areas. Because the sun warms up concrete faster than it does plants and trees, and because concrete is more abundant in urban areas, the city becomes a big hot-aired area (heat island) all year round. This makes cities extremely hot, leading to an increased use of air conditioners and other cooling technologies.
This effect decreases with the more green spaces we incorporate in a city. Through the daily evaporation cycle, plants are able to cool down entire cities, reducing the UHI effect. Therefore, the plants themselves will be covering what would have otherwise been a concrete rooftop, one of the main causes of UHI itself. Its is scientifically proven that by using the Bee Green garden mat, It acts as a great heat absorbing insulation and it keeps the temperature levels cooler. The Bee Green garden mat helps to reduce the air conditioning and in return saves energy by 20% to 30%. by having green roofs in your houses, apartments and in commercial buildings.
6. Urban agriculture
With rooftop gardens comes another environmentally friendly and booming initiative – urban agriculture. This involves using green roofs as miniature farms that actually produce fresh food. We at Bee Green has a range of 100% natural products to select from to make your rooftop a farm. You can grow tomatoes, bell pepper, cucumber, strawberries etc… all in your rooftop and eat fresh organic fruits and vegetables using our range of coir base products.
7. Less noise
The Bee Green garden mat that we provide for rooftop gardens not only can be applied to temperatures but also to noise. The combination of soil and plants can help to absorb, reflect, or deflect sound waves, providing the building with excellent noise reduction.
This could be greatly beneficial in decreasing noise pollution in busy cities or areas that are located near airports or underneath flight paths.
Other than the different types of bushes, trees, plants, and invertebrates rooftop gardens can harvest, they can also be a perfect habitat for many birds, and act as a stopover for migrating species, allowing two different type of these to come into contact.
