The path traced in construction sector leads to an increased attention to building heritage and its refurbishment into “nearly zero-energy buildings”. The regeneration process of an existing building is complex and requires the designer to use the distinctive features of the building and of the site where is built in order to achieve the objectives. One of the most important moments of this process is the choice of the interventions. The objective of this research is to identify a replicable decision-making method to support the designer in identifying the optimum solution through the Operations Research.
More than thirty years after the definition of sustainable development, the commitment to protect the planet has been renewed, and all sectors of human activity have been called to contribute to this critical challenge of our time. Therefore, the construction sector can also make an essential contribution. Designers are called upon to modify their actions to consider the environmental, social, and economic impacts during the entire life cycle of construction. The digital revolution could be a suitable opportunity for a profound renewal oriented towards sustainability. The new digital technologies and the increased computing power are useful for managing the increasing complexity in current projects and supporting collaboration between the many experts involved. The presented research analyzes the current state and identifies the signs of change and the cues to imagine possible virtuous complicity between sustainable development goals and the digital revolution’s potential, which is supported by the operational features of optimization methods. Based on this in-depth analysis, an operational strategy has been defined, combining the three macro themes usually treated separately—sustainability, digitization, and optimization. This strategy can be a valuable tool to guide designers in optimizing the process of sustainable design and regenerative construction.
Small municipalities, if taken individually, have difficulty in implementing energy policy and sustainable projects (economic, environmental and social), because they do not have sufficient financial and human resources. The idea is to regenerate a territorial area following the principles of innovation and sustainable development, that is the applicability of the concept of Smart Villages on an entire “small” territory with homogenous characteristics (similar morphology, coastal village or bordering the coast, tourism as the main business, ect.) and with several villages with less of 3000 habitants; this is the “Golfo dell’Isola” in Liguria.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
