“…Planning the life cycle of a building (or building elements) becomes imperative to support the decision-making process, and this is demonstrated by the numerous studies in which optimization strategies, based on very different approaches, are developed in the literature, ranging from genetic algorithms to combined Life Cycle Assessment (LCA) and LCC procedures [6][7][8][9]. This allows an increased awareness of the burden of both the costs and environmental impacts of alternative technological and design solutions at every stage of the life cycle (from the raw materials supplied for the construction process to the demolition at the end of its useful life) [10][11][12][13][14]. In Italy, the attempts to apply technical-economic evaluations on energy saving strategies are numerous and are not only limited to the building envelope components but also extend to the technical systems, which are designed to maintain comfort conditions [15][16][17].…”

Energy Upgrading of Residential Building Stock: Use of Life Cycle Cost Analysis to Assess Interventions on Social Housing in Italy

The debate on the relevance of the global sustainability (including energy, environmental, social, economic, and political aspects) of building stock is becoming increasingly important in Europe. In this context, special attention is placed on the refurbishment of existing buildings, in particular those characterized by significant volumes and poor energy performance. Directive 2012/27/EU introduced stringent constraints (often disregarded) for public administrations to ensure a minimum yearly renovation quota of its building stock. This study describes how Life Cycle Cost analysis (LCC) can be used as a tool to identify the “cost-optimal level” among different design solutions to improve the energy performance of existing buildings. With this aim, a social housing building located in the town of Pisa (Italy) was chosen as the case study, for which two alternative renovation designs were compared using the LCC methodology to identify the optimal solution. The two alternatives were characterized by the same energy performance—one was based on the demolition of the existing building and the construction of a new building (with a wooden frame structure, as proposed by the public company owner of the building), while the other was based on the renovation of the existing building. This study can provide useful information, especially for designers and public authorities, about the relevance of the economic issues related to the renovation of social housing in a Mediterranean climate.

“…Other works addressed the management of mechanical equipment status considering the BIM authoring perspective [58]. However, as far as the management of the buildings' equipment is concerned, most studies focused on refurbishment methods based on BIM [59], while research on their life cycle maintenance activities is poorly addressed [42].…”

“…In recent years, these issues have also received greater attention in the construction sector, focusing on the development of solutions for sustainable buildings [41]. In fact, most studies have investigated the application of a life-cycle thinking approach to improve the environmental performances of buildings [42]. Whereas a few studies have addressed facility management by means of the PSS approach, discussing its integration with BIM solutions has only occurred thus far at a general level [43,44].…”

A BIM-based PSS Approach for the Management of Maintenance Operations of Building Equipment

The service-centered economy has grown considerably in the last few years, shifting from product-based solutions towards service centered offerings, i.e., Product-Service System (PSS) solutions. Such an approach is also emerging in the context of building equipment, where maintenance activities play a fundamental role in facility management. In this field, Building Information Modeling (BIM) based tools are diffusely used to improve the performances of facility management. However, few studies have addressed the above issues while considering a shift from product-based approaches in favor of more advanced servitization models. The study aims at integrating BIM based approaches in a PSS context for the improvement of the management of maintenance operations of building equipment. A general framework for maintenance management has been developed, merging the implementation of the PSS components in a BIM model for the definition of maintenance management. A first application of this methodology to a real case study concerning the elevators of an existing building has shown the efficacy of the proposed approach. The study highlighted the benefits that can be achieved, especially in terms of reduced periods of equipment unavailability, reduced costs and augmented customer satisfaction, while enhancing the information exchange between the PSS actors. Hence, although further research is still needed for its validation, the proposed approach can offer practical insights for the development of promising BIM-based PSS solutions for facility management in the construction industry.

“…Developing timber buildings can be a good solution for sustainable and circular cities. Hossain and Ng indicate that in comparison to residential buildings constructed with concrete, about 25% lower carbon emission level can be achieved if residential buildings are made of wood (Hossain & Ng, 2018). Therefore, wood can be considered as a circular material, additionally being renewable and thus sustainable as well.…”

The concept of circular economy have gained a popularity in the scientific areas for the past decades due to raising influence of climate change, overpopulation, deforestation, resource depletion, urbanization, pollution and other global issues. Real estate is crucial aspect for every human being, because majority of people spend majority of their lifetime in buildings which are mainly located in cities. Purpose of the study is to reflect how built environment and real estate industry can benefit from the features of circular economy concept while promoting the practices of sustainable development. Authors have carried out a study based on the methodology of literature review and state of the art review to show how features of circular economy can support practices of sustainable construction. Results show that the construction processes can be supported by features of circular economy throughout the whole life cycle of construction project including logistics, supply chains, design, manufacturing process, exploitation and maintenance of real estate and reusing the building materials. Research indicates that urban circular economy contributes to the development of sustainable societies. Additionally, efficient implementation of circular construction requires profitability for majority of stakeholders.
