Roof Garden, Make Our Earth Healthier
There are too many ways that we can do to participate about reducing global warming. One simple thing that we can do is making roof garden as component of architecture design while you plan your home.
Green space that included roof garden as a campaign, gave evidence that city temperature decrease until 4,2°C, absorb pollutant gas (carbon dioxides, dust particles), reduce heat island, and reduce sun radiation (until 80 persen), reduce noise.
Roof green garden absorb rain water and keep a while in soil layers, and cooling the roof, so we can reduce our AC power. Roof garden as natural insulator cooling building from 58°C to 31°C, and decrease room temperature 3-4° lower than outside, so we can save AC power supply at least 15%/year.
Roof garden converts and absorbs rain water until 75% to use to pour closet, plants, wash your car. Roof garden protect your waterproofing from ultraviolet radiation, extreme fluctuation of temperature, physically damages, and give more ages for the building at least 20 years.
Roof garden with 155 m2 of wide produce oxygen that enough for one man per 24 hours. Roof garden with trees produce oxygen for 10 people pe hours. The optimalization of roof garden become accessible public space increase environment friendly and power saving property value in 6-15% (USA, UK, and Singapore).
Two Function
Roof garden has two functions, intensive characteristic and extensive characteristic. Intensive means that activities that do in roof garden really active and have variations, also many people involved. Extensive means that roof garden only have one activity, and limited people.
Roof garden little bit different then conventional garden. You have give attention about sun light, temperature, air, wind, rain, and security especially for children.
Although roof garden technology growth rapidly, we can make it with simple technology and cheaper. Technically, roof garden development requires stronger roof structure then usually in order to hold addition load. The thickness of plants media influence the roof mulberry.
Tecnology progresses make plants layer media can be 10-20 cm of thickness. Garden roof consist of waterproofing base layer, sub drainage, geotextile or palm fiber and sands, topsoil, soil coverer (grass, or bush). To plant trees, there are separated pots.
Garden roof design growth rapidly, follows building needed. Garden roof can develop become open café, pool, sports field or mini golf, organic vegetables, therapy garden, connector plaza between buildings, etc.
At garden roof, we sun panels can be placed as power sources. Building greening as roof garden in huge building will change common people perception while they build their own house, so they interest to build environment friendly house. Hope so…
