Algunos de los beneficios incluyen:
Rooftop gardens can lead to less and more effective use of energy. They provide added insulation, minimizing heat loss in winter and keep temperatures cool in summer thanks to its protection from direct sun exposure. This energy conservation means fewer greenhouse gas emissions. Additionally, rooftop gardens contribute to a decrease in the use of heating, ventilation, and air conditioning systems.
Control del sobrecalentamiento urbano
The Urban Heat Island (UHI) concept is based on the increased temperature levels found in urban areas. Solar radiation warms up concrete and asphalt faster and to warmer temperatures than trees, plants, and greenery. The result is a big zone of hot air –a heat island– surrounding urban environments. Even though this might be beneficial in winter; it makes cities unbearably hot in summer. The resulting rise in energy demand, by the use of air conditioners and other cooling equipment, puts an excessive pressure on electrical grids. Through transpiration and evaporation, plants cool down entire cities. Therefore, the UHI effect decreases as more green spaces are incorporated to the city.
Compost como medio de reducción de residuos
Organic waste is an unfortunate and abundant addition to land fill areas around the world. Buildup of this decomposing organic material causes a rise of methane gas which is highly toxic to the air and soil. It is also 20 times more effective at trapping heat into the atmosphere than carbon dioxide is, contributing enormously to global warming.
Placed in the stairwell of each floor of our building, you’ll find waste bins separated by type of debris. Organic matter can be deposited by our guests, which is brought upstairs and added to our active compost pile. Within 45-90 days this waste in turned into remarkable compost, which gives needed nutrition to our garden. As a city-wide effort to make use of organic refuse still does not exist, we make the effort to gather a great deal of refuse from many of the local vegetable stands and add it to our compost turner.
Uso eficaz del agua de lluvia
Otro de los beneficios de una terraza con huerta orgánica es que controla el agua de lluvia. Luego de llover, las plantas almacenan agua para utilizarla luego y le regresan el resto al medio ambiente a través de transpiración y evaporación. Además, la escorrentía de este tipo de terrazas verdes reduce su volumen y es más pulcra que el de las terrazas convencionales, por lo que aliviana las infraestructuras locales y los sistemas cloacales.
Reducción de smog e incremento de la calidad de aire
One of the greatest benefits of roof gardens is their ability to filter polluted air particles, as well as gases, and to reduce the production of smog. Green roofs filter the air not only through plant’s photosynthesis process, but also by deposition in the soil of the growing area. This leads to lessening greenhouse emissions in urban areas.
Preventing combined sewer overflow.
Reducing carbon monoxide impact.
Removing nitrogen pollution from rain.
Neutralizing acid rain effect.
