What are the root causes hindering the implementation of green roofs in urban China?

Function-Based and Multi-Scale Approach to Green Roof Guidelines for Urban Sustainability Transitions: The Case of Bogota

“…Several authors have found a correlation between the higher number of implemented green roofs and walls in specific regions and the existence of policy instruments and guidance tools, in comparison to local environments where the latter do not exist and which display a lower number of implementations [28]. This is partly due to the fact that guidelines build understanding of the technology, which creates capabilities to overcome uncertainties and myths associated with a niche practice [29]. Lack of knowledge and proper understanding of the set of physical components of a socio-technical system results in failures that slow down or constrain the growth of a given practice-in this case, green roofs [18].…”

“…Given the multifunctional nature of green roofs and other forms of infrastructure, and the multiple benefits associated with them, this practice is among the most effective ways to trigger positive incremental change in cities [3]. Thus, the role of local governments and participatory networks like non-governmental organizations (NGOs) in guiding multiple key actors through local guidelines is crucial to overcome barriers [29]. We support authors who argue that participatory guidelines contribute to acceptance, good perception, and awareness from various parties, and that they can encourage the niche growth in developing countries [37].…”

Solar Green Roofs: A Unified Outlook 20 Years On

“…Four root causes were lately identified by Chinese scholars to limit green roof penetration in China's cities: increased maintenance, design and construction costs, poor arrangement of the use of green roofs, and lack of incentives toward developers . The team recommended the deployment of financial incentives and new mandatory regulation together with better dissemination of the benefits “particularly lifecycle cost benefit, among building stakeholders.”…”

[42] The team recommended the deployment of financial incentives and new mandatory regulation together with better dissemination of the benefits "particularly lifecycle cost benefit, among building stakeholders." [42] No better dissemination argument, we add in conclusion, than focusing on the prolonged economic benefits offered by a solar green roof whose enhanced electricity production will rapidly repay the extra cost incurred to install and maintain the green roof, especially today when the state-of-the-art PV modules are certified to last at least 30 years while losing less than 0.4% of their original productivity every year.…”

Solar Green Roofs: A Unified Outlook Twenty Years On

“…[39] Four root causes were lately identified by Chinese scholars to limit green roof penetration in China's cities: increased maintenance, design and construction costs, poor arrangement of the use of green roofs, and lack of incentives towards developers. [40] The team recommended the deployment of financial incentives and new mandatory regulation together with better dissemination "of the benefits, particularly lifecycle cost benefit, among building stakeholders". [40] No better dissemination argument, we add, than focusing on the immediate and prolonged economic benefits derived by the installation of a solar green roof whose electricity production is enhanced in comparison to a conventional rooftop PV array substantially paying by itself the extra cost incurred to design, install and maintain the green roof, especially today that a PV array will last at least 30 consecutive years with today's state of the art modules (most of which are produced in China) losing less than 0.4% of their original productivity every year.…”
