The Special Issue entitled "Phase Change Materials and Building Systems Dynamics" aims to provide an integrated approach to the interactions and modeling between phase change materials embedded in the passive and active engineering systems dynamics of the built environment towards economic growth decoupling from resource depletion and environmental degradation in different levels. This Special Issue belongs to the Section "Sustainable Materials". ----------------------------------------------- Dear Colleagues, Phase change materials and their integration in the built environment, both in passive and active systems, are one of the promising methods to provide latent storage towards peak load reduction and/or energy savings optimization. Since engineering systems interact with their environment, knowledge of their impacts is always of utmost importance toward the transition to sustainable living. The linkage between the sustainable life circles of phase change materials and the optimal modeling of interaction dynamics, the cost-effectiveness, and the strategic mechanisms to support the guidance of the framework of the system are of paramount interest, especially in recent years that technosphere and ecosphere boundaries urgently require a balance. In addition, many efforts are directed on, as well as debating, decoupling economic growth from resource depletion and environmental degradation at different levels. Within this context, phase change materials and systems dynamic interactions seem to be crucial substances for comprehension in the light of challenging issues, which are still unsolved. Synergies with established tools and standards and efficient symbiosis taking into account the dynamics and hidden potential provide a deeper insight, due to materials’ impact on the whole economic and social life of human activities, the built environment, the production and consumption systems, and the supply chain procedures, to name some. The Special Issue seeks to identify contributions referring to design and modeling of latent storage systems, the quality of phase change materials and system dynamics interactions, business and management model deployment, phase change materials and energy stock and flows in ecological processes, the functionality and optimal operation research modeling, nature-inspired design and biomimicry, decision-making processes, and indirect metamaterials analysis effects. Best practices and case studies are also welcome. Dr. Vasileios C. Kapsalis Guest Editor https://www.mdpi.com/journal/sustainability/special_issues/PCMBSD

Dear Colleagues, The tremendous effort to achieve sustainable energy production and consumption has been acquiring a global interest, since it includes variable competitive approaches and contradicting preferences of the stakeholders. The technological advances, the socio-economic parameters involvement and the environmental impacts, outline a wide range of applicability of novel models and establish a better insight of the mechanisms of the market diffusion processes. The 18th European Roundtable for Sustainable Consumption and Production (ERSCP2017), which will be held on the island of Skiathos, Greece, 1–5 October 2017, discusses the latest advances in a regional and global level of the above issues and attracts the scientific interest of many first order experts in the field. In this sense, this Special Issue selects papers that are subject to a rigorous peer review procedure, and disseminates an active interaction between the multi-disciplinary dynamics of the discussion outputs, the resource efficiency necessity and the low carbon transition, accordingly. We welcome literature reviews, research papers and case studies with a comprehensive interaction with the abovementioned topics and may not be restricted to those presented during the 18th ERSCP2017. Keywords: Energy, Renewables, Environment, Industry, Sustainable Development, Environmental Systems, Technology Economics This special issue is now open for submission to the following link: http://www.mdpi.com/journal/energies/special_issues/ERSCP_2017 Energies is an open access journal of related scientific research, technology development, engineering, and the studies in policy and management and is published monthly online by MDPI.
