Regulations and funding schemes are evolving quickly from these strategies and will push the innovation within the greening sector forward. ![]() ![]() The successfully implementation of NBS in future requires know-how and constant training and education to recognize innovations and potentials and represent the basis for decision making to environmental issues. These will be triggered by pro-active strategies of cities who take greening technologies already strongly into account. According to the green market studies, a dynamic growth is expected for the next years due to rising awareness for the need of climate change adaption measures and investments in NBS. Various relevant framework strategies have been developed to aim towards a more sustainable, resource and energy efficient building sector. ![]() These research initiatives highlight the importance of market data as a basis for decision-makers. The study aims to show the strong economic potential of the green market using the examples of Germany, Austria, and the Czech Republic. As a result, the European Commission adopted the Renovation Wave initiative as part of the European Green Deal to support the capacity of green infrastructures. Therefore, Nature-Based Solutions (NBS) on buildings have gained ground in recent years due to their growing importance. The rising temperatures and the extreme weather events (heat, drought, storms), as well as changes in precipitation patterns, put pressure on ecosystems and urban population. But today’s green roofs tend to be larger, urban installations that may include wildlife habitat, gardening space, greywater filtration, and solar or wind technology.Our climate is being particularly challenged by different anthropogenic influences that amplify the negative impacts of climate change. Like the ancient roofs, the new ones absorb rainwater and provide insulation. The old sod roofs were “green” both literally and figuratively, but they aren’t the genesis of the living or eco roof that emerged in the 1960s. Turf roofs are still used for vacation houses in Norway, the sod applied now over a dimpled plastic drainage membrane atop bitumen roofing felt over wood sheathing. They enjoyed a romantic revival by the end of the 19th century, especially for mountain lodges and museum buildings. In rural areas, sod roofs were common into the 18th century, to be superseded by tile and metal. The grassy roofs are called torvtak in Norway and Sweden. Traditional Scandinavian roofs relied instead on several layers of birch bark (acting as a water seal) beneath the sod. In this 20th-century example, a layer of asphalt under corrugated cementitious material separates the turf (consisting of grasses, soil, and roots) from the roof sheathing. Reassembling it in the 1950s started the building careers of several local men. ![]() The technique is ancient and ingenious.Īt the top of a field of wildflowers, the Norwegian log cabin with a sod roof overlooks a secluded cove on a Maine island. The extra weight of the sod roof locks the stacked logs tightly in place, and prevents drafts. It also plays a critical part in the construction of the house: Each log is shaped to cradle with the log below it. The owners affirm that the old-world feature keeps the interior cool in summer and provides some insulation in winter. Crowning the Norwegian log cabin in Maine is a sod roof.
