Abstract [en]

The interest in alternative green solutions in cities is increasing in Sweden due to increased urban densification. As cities become dense it is usually at the expense of green areas. Creating green infrastructure on buildings, for example with help from different types of green walls, is a way to solve this problem. Many benefits of green walls are highlighted by its proponents, including a positive impact on the environment and health. The newest addition among green walls is so called living walls where the root system grows on substrate in modules or other system placed on the facade. These differ from the more traditional green facades with plants that are planted in the soil and then grow vertically up the facade. It is only in recent years that living walls have been built in outdoor public places in Sweden and a lot of knowledge and experience are still missing concerning the process and organization to plan, build and maintain living walls in Sweden. This study presents the experiences of challenges and opportunities connected to the planning, implementation and maintenance of living walls in a Swedish climate. Interviews with stakeholders involved in five existing Swedish living wall projects have been included in the study together with a literature review. The result of the study indicates a number of challenges and opportunities in connection to living walls in a Swedish climate based on six general areas - technology, plants, organizational and regulatory framework, knowledge and experience, finance, and operation and maintenance. Among other things, a lack of knowledge and experience of living walls is identified, both among the public and potential new customers as well as in the industry, which impedes with the development of living walls in Sweden. More good examples and increased dissemination of the knowledge and experience from existing living wall projects is requested. Meanwhile, it is already possible to see a positive trend with an increasing number living walls in Sweden where the knowledge and experience is increasing with each new project. This study also shows the importance of good cooperation and communication between the stakeholders involved, where especially the organization that is responsible for maintenance plays a very important role for the survival of a living wall. Experiences show that close cooperation, at an early stage of planning, between those who put up the wall and those who will later be responsible for maintenance gives a better end result, while the non-existent collaboration is regarded as a considerable obstacle for the later maintenance. More challenges include the management of advanced irrigation systems, plant survival during the winter and a high investment cost. This report is only available in Swedish.
