Planting in containers prevents added stress to the roof's waterproofing. Plantings in containers are used extensively in roof top gardens. Hydroponics and other alternative methods can expand the possibilities of roof top gardening by reducing, for example, the need for soil or its tremendous weight. The garden may be on the roof of an autonomous building which takes care of its own water and waste. An urban garden can supplement the diets of the community it feeds with fresh produce and provide a tangible tie to food production.” At Trent University, there is currently a working rooftop garden which provides food to the student café and local citizens.Īvailable gardening areas in cities are often seriously lacking, which is likely the key impetus for many roof gardens. “In an accessible rooftop garden, space becomes available for localized small-scale urban agriculture, a source of local food production. “If widely adopted, rooftop gardens could reduce the urban heat island, which would decrease smog episodes, problems associated with heat stress and further lower energy consumption.” Roof gardens are obviously very beneficial in reducing the effects of temperature against roofs without gardens. The study shows temperature effects on different layers of each roof at different times of the day. Ī study at the National Research Council of Canada showed the differences between roofs with gardens and roofs without gardens against temperature. The study was performed by the University of Cardiff. Plant surfaces however, as a result of transpiration, do not rise more than 4–5 ☌ (7–9 ☏) above the ambient and are sometimes cooler." This then translates into a cooling of the environment between 3.6–11.3 ☌ (6.5–20.3 ☏), depending on the area on earth (in hotter areas, the environmental temperature will cool more). "The primary cause of heat build-up in cities is insolation, the absorption of solar radiation by roads and buildings in the city and the storage of this heat in the building material and its subsequent re-radiation. Plants have the ability to reduce the overall heat absorption of the building which then reduces energy consumption for cooling. Roof gardens are most often found in urban environments. Infinity edge pool at Sands Sky Park, Marina Bay Sands Hotel, Singapore Īmong the Seven Wonders of the Ancient World, The Hanging Gardens of Babylon are often depicted as tall structures holding vegetation even immense trees. The medieval Egyptian city of Fustat had a number of high-rise buildings that Nasir Khusraw in the early 11th century described as rising up to 14 stories, with roof gardens on the top story complete with ox-drawn water wheels for irrigating them. A roof garden has also been discovered around an audience hall in Roman-Byzantine Caesarea. An example in Roman times was the Villa of the Mysteries in Pompeii, which had an elevated terrace where plants were grown. I would highly recommend Lisa to anyone looking to transform their outdoor spaces, gardens and land.Humans have grown plants atop structures since the ziggurats of ancient Mesopotamia (4th millennium BC–600 BC) had plantings of trees and shrubs on aboveground terraces. It was also part of the towns submitting to the ‘Britain in Bloom’ competition in 2019 The project has been recognised by Harrogate in Bloom, who presented the school with a special trophy at their annual awards ceremony in recognition of the quality of the garden. The wellbeing, wildlife garden area will be a lasting and sustainable resource for children of all ages to enjoy and learn in a creative and beautifully designed area. Throughout the process, Lisa has shown the flexibility to adapt her design, involve the whole community and show real dedication and commitment in finding ways to fund the different elements of the project. Lisa has considered the needs of all children and has made the garden fully open and accessible to children with a wide range of needs. It makes maximum use of the space available and cleverly weaves the themes of sustainability, care for the environment and care for wildlife together in a way, which places the child’s experience at the heart of the design. The school’s new wellbeing, wildlife garden area cleverly connects areas for growing, exploring learning and coming together for shared activities. Lisa has done an outstanding job in transforming an overgrown and underused area of land into a superb garden area, which exceeds the brief that she, was originally given.
