Green roofs are increasing in popularity because of both their pleasant appearance and their positive effects for the urban ecosystems and the building indoor climatic conditions. Though this technology has already been applied all over the world, it is still commonly considered of difficult application and management. Easy and fast approaches for green roofs must therefore be examined and encouraged in order to increase their number to counterbalance urban overheating. This thesis case study aimed to represent a prototype of a green roof integrated with a residential function in order to achieve an easy management of the cultivation area. The project was designed in terms of sustainability and was analyzed for its social, environmental and economic impacts, pointing out the numerous benefits that can be derived by the combination and juxtaposition of humans and native plants. The proposed solution is favorable in terms of a sustainable development: it aspires to be reproduced and extensively applied to other facilities of a city as a solution for the overheating and overpopulation of contemporary cities.

Arthropod Abundance

Worldwide, urban areas are expanding both in size and number, which results in a decline in habitats suitable for urban flora and fauna. The construction of urban green features, such as green roofs, may provide suitable habitat patches for many species in urban areas. On green roofs, two approaches have been used to select plants—i.e., matching similar habitat to green roofs (habitat template approach) or identifying plants with suitable traits (plant trait approach). While both approaches may result in suitable habitats for arthropods, how arthropods respond to different combinations of plants is an open question. The aim of this study was to investigate how the structural complexity of different plant forms can affect the abundance and richness of arthropods on green roofs. The experimental design crossed the presence and absence of annuals with three Sedum sediforme (Jacq.) Pau (common name: stonecrops) treatments—i.e., uniformly disrupted Sedum, clumped disrupted Sedum, and no Sedum. We hypothesized that an increased structural diversity due to the coexistence of different life forms of plants on roofs is positively related to the abundance and richness of arthropods. We found that arthropod abundance and richness were positively associated with the percent of vegetation cover and negatively associated with substrate temperature. Neither arthropod abundance nor richness was influenced by the relative moisture of substrate. We also found that arthropod abundance and richness varied by green roof setups (treatments) and by seasonality. Arthropod abundance on green roofs was the highest in treatments with annuals only, while species richness was slightly similar between treatments containing annuals but varied between sampling periods. This study suggests that adding annuals to traditional Sedum roofs has positive effects on arthropods. This finding can support the development of biodiverse cities because most extensive green roofs are inaccessible to the public and can provide undisturbed habitat for several plant and arthropod species.

Analytical Review

Over the past 20 years, a large number of studies have been published on reducing storm runoff by various types of green roofs. This article analyzes the results of experimental studies presented in 39 publications on green roof runoff reduction in a climate similar to the climate of Russia: in Canada, the USA, Finland, Norway, France. An analytical review found that the ability of green roofs to retain rainfall varies from 20 to 99.5% depending on climatic conditions (duration and intensity of rains, duration of dry periods, solar radiation, temperature and humidity, wind conditions), the properties of green roof layers (moisture capacity of the substrate and a drainage layer, the substrate thickness), the type of vegetation, the geometry of a green roof (slope and orientation). Green roofs can be a useful tool for reducing urban storm water runoff. However, in order to ensure high efficiency, it is necessary to use green roof technology with other measures to reduce runoff.

Research Challenge

The research challenge in the problem of the sustainable development goals is to find solutions for development control through the application of green roofs in residential areas, which is the feasibility of the role of the community. This research was based on the discipline of architecture by considering the role of the community in managing architectural green-space substitution. The purpose of this study was to identify patterns of the role of the community for green roofs feasibility based on housing, conducted in some parts of Sumatra, Java, and East Nusa Tenggara, Indonesia. Data were collected using a survey questionnaire. Data were calculated based on percentages and analyzed using the chi-square method. The results indicated that the optimization of the community role was needed for the sustainability of the green-roof from all economic levels, both urban and rural. The aspect of public awareness and knowledge of the benefits of the green-roof is very high, but the object of the green-roof in Indonesia is still very limited because participation is still not optimal. Therefore, it is necessary to promote the green-roof application to the community by adapting local culture in sustainable green-roof technology innovation.

The concept of sustainable urban design has appeared in different perspectives to minimize and reduce the negative impacts of urban expansion in terms of climatic and environmental drawbacks. One of the undeniable approaches of sustainable urban design is the adoption of green urban roofs. Green roofs are seen to have a substantial role in addressing and resolving environmental issues in the context of climate change. Research investigations have indicated that green roofs have a remarkable impact on decreasing rainwater runoff, reducing the heat island effect in urban spaces, and increasing biodiversity. Nevertheless, green roofs in urban spaces as a competent alternative to nature remains a standing question. To what extent can green roofs mimic the biodiversity that is seen in nature? Moreover, to what level is this approach practical for achieving a tangible reconnection with nature, or so-called biophilia? This study attempts to discuss the essence and impact of green roofs in urban spaces based on a case study approach. The study reflected lessons from the New York High Line Green Roof regarding biophilia and biodiversity in this case study. It concludes with key lessons that can be transferred to other urban spaces with similar settings.

The problems related to sustainable development (SD) cover changes over time and space, as well as the interpenetrating relationships in economic, social, environmental, institutional and spatial spheres. The development, in line with the concept of sustainable development, takes place when all changes occurring in the environment are focused on improving the quality of life of the Earth’s population, following the principles of environment resources’ protection at the level allowing the development of future generations. SD concept remains one of the goals underlying developmental policies conducted at the global, EU, national and regional level. Therefore, the question arises how the developmental changes in one area manifest in others in the space of territorial units. The research was conducted for socio –economic areas, where through improvements in economic activity conditions, positive effects in areas of unemployment and poverty are expected. The analysed phenomena, described using indicators, are structured in accordance with the principle: from a problem to its solution, PSR (pressure‑state‑response). Methodology of the SD evaluation in the PSR framework is based on aggregate measures, correlation analysis, spatial statistics and macro evaluation of changes using `change matrix’. The analysis was carried out for the panel of data referring to the poviats in Poland in the period 2009–2014.

The 2030 Agenda for Sustainable Development brought the critical challenge of how private capital can support its new goals—the Sustainable Development Goals (SDGs)—to the attention of finance, business and policy actors. Impact finance instruments, which aim to obtain both financial and positive social/environmental returns simultaneously, can serve as effective institutional mechanisms to support the financing of SDGs. Social impact bonds (SIBs) are part of this emerging field. SIBs represent multi-stakeholder partnerships, built on outcome-based contracts, designed to harness private impact-oriented investors, service providers and public entities to address social or environmental problems. SDG 17 considers partnerships priority instruments for the achievement of SDs targets. This paper provides an exploratory analysis into the field of Social Impact Bonds and aims to (i) understand how such instruments are suitable for involving sustainable economy actors in SDG-based partnerships; (ii) determine the interplay between SIBs and SDGs. In order to address these questions, the article presents a multiple case study that includes a cross case analysis of four SIBs experienced in different social policy areas and different countries. As secondary step, the study matches phases and activities of SDG-based financial partnerships derived from a literature review with those experienced by each SIB case study. The results show that SIBs are fully compliant with SDG-based financial partnership structures derived from the literature, and their architecture reveals a high degree of SDG investment readiness. The originality of the research consists of including SIBs in the analysis of the new financial tools for the achievement of the SDGs, and extending them into the field of partnerships for the Goals, at the center of SDG 17. The paper fills the significant gap in the current research related to the issues of financing sustainable development and financial sector instruments on sustainability.

In this period of increasing urbanization, cultural heritage can play a key role to achieve sustainable development, as widely recognized by international institutions (i.e., United Nations (UN), UN Educational, Scientific and Cultural Organization (UNESCO), International Council on Monuments and Sites (ICOMOS)). In this perspective, it is necessary to operationalize the principles stated at international level and thus new approaches and tools are required. The paper aims to understand the relationships between the implementation of adaptive reuse projects and their success (or not) in terms of impacts on the buildings themselves and on the urban context. The assessment framework for evaluating the impacts of heritage conservation and rehabilitation projects is described through the analysis and comparison of two Italian case studies: the Ancient Market and the Basilica of St. Peter the Apostle, in Siracusa (Italy). Although realized both in the same place (Ortigia, the historic centre of Siracusa), during the same period and by the same architect, these two interventions have produced different results in terms of urban development. A set of indicators, deduced from recent scientific studies, has been used to analyse the different impacts on physical, cultural, social, environmental and economic systems. To understand in depth the causes of these two different results, a survey has been carried out involving experts. The proposed indicators used for the ex-post evaluation can be also adopted in other contexts and for ex ante evaluation, in order to orient the strategic design choices in cultural heritage adaptive reuse projects.

Mediterranean Conditions

Green roof typology can vary depending on buildings structure, climate conditions, substrate, and plants used. In regions with hot and dry summers, such as the Mediterranean region, irrigation plays an essential role, as the highest temperatures occur during the driest period of the year. Irrigation might reduce the heat island effect and improve the cooling of buildings during this period, however, the added cost of maintenance operations and additional energy consumption could outrun the benefits provided by the project. Moreover, in situations where water is scarce or primarily channelled to other uses (e.g., domestic, agriculture or industry) during drought occurrence, it is advisable to implement green roof projects with the lowest use of water possible. The objective of the present work is to investigate solutions to optimize water use in green roofs under Mediterranean conditions, such as those of southern Europe. Two case studies are presented for Portugal, and potential techniques to reduce irrigation requirements in green roofs were tested. These addressed the use of native plant species, including the extreme type of a non-irrigated green roof (Biocrust roof) and techniques for plant installation. Plant drought tolerance was found to be an advantage in green roofs under these climatic conditions and, for the species studied, aesthetic value could be maintained when irrigation decreased.

The Impact

In urban areas, a considerable proportion of energy demand is allocated to buildings. Since rooftops constitute one-fourth of all urban surfaces, an increasing amount of attention is paid to achieving the most efficient shapes and component designs compatible with every climate and urban context, for rooftops of varying sizes. In this study, three types of rooftop technologies, namely insulated, green roof, and rooftop greenhouse, are evaluated for energy and thermal performance using computer simulations. Water surface exposure, absorption, and intrusion are the three important factors in the calculation of hygrothermal models that impact energy consumption and building envelope performance; however, a few studies are specifically focused on providing realistic results in multi-dimensional hygrothermal models and the assessment of the impact of moisture in roofing solutions. This paper aims at evaluating the performance of three different roofing technologies through a two-dimensional hygrothermal simulation in software WUFI. To accomplish this, a precise localized microclimate model of a complex urban context on the scale of a neighborhood was employed to evaluate the cooling and heating loads of the buildings, the impact of the water content in the green roof on the thermal behavior of the roof surface, and the feasibility of designing a building with nearly zero cooling needs. A two-story building in the city center of Bologna, Italy is modelled. Simulation results have shown that during the cooling period, the performance of the designed rooftop greenhouse is the most effective by 50% reduction in cooling loads. Besides, the impact of moisture in green roofs has been detected as a negative factor for thermal and energy performance of the building in the Mediterranean climate. The results ultimately highlighted the capability of passively-designed rooftop greenhouses to create a building with nearly zero cooling needs.
