“…Accurately estimating the real energy and economic savings of a building (Pallis et al, 2021;Yun et al, 2020;Giraudet, 2020;Dominguez-Delgado et al, 2020) requires an adequate knowledge of the building-plant system, or the characteristics of the building envelope, but also of the plant components present and how these two systems interact with each other. Enhancing the energy supply chain of Italian hospitals (Moro Visconti et al, 2020;Klemeš et al 2020;Sarkis, 2020;Martiniello et al, 2020) is a strategic priority that requires investment, simplification of authorization procedures and a push to the conversion of traditional buildings in the key of circular economy (Khadim et al, 2022, Marino & Pariso, 2022. In this context, energy efficiency can make an essential contribution to the transition to stimulating economic growth (Khan et al, 2021;Kahouli, 2018;Zhou et al, 2021).…”

Analyzing the complex structures of 1062 Italian hospitals, the present research aims at evaluating the performance relating to the sustainable energy management. The monitoring activities were carried out both to analyze the building and structural context and to analyze the energy consumption of Italian hospitals during the period 2016-2022. Furthermore, the paper elaborates a comparative analysis the other European countries, highlighting how is possible to improve the energy efficiency of Italian hospitals. The energy analysis concerned the breakdown of electricity consumption, analysis of the consumption of the last six years derived from the monthly bills of hospitals, the consumption now, distribution of electricity consumption, and air conditioning needs; the organizational analysis concerned the plant characteristics of the structure, the age of the building and building maintenance over the last 6 years. In the discussion, possible solutions emerge, operational interventions, to make the energy management of hospitals, more efficient. The presence of different services provided highlight different profiles of energy consumption linked to two main categories: hotel-type consumption for the well-being of patients and staff and consumption more closely related to health functions supported by treatment and diagnosis equipment. In recent years, numerous opportunities for energy upgrading of buildings have not been implemented by creating energy profiles of obsolete and inefficient hospital facilities. In this context, the role of the energy manager and the presence of structures dedicated to energy management emerge as the main bottlenecks for achieving better energy efficiency. After the introduction, the paper elaborates a conceptual background focused on sustainable energy management. The section 3 show the methodology applied, the main results are included in section 4 and the discussion section have been developed in section 5. Finally, the conclusion highlights that the sustainable energy management is an open question and the output of discussion linked to the research suggest that the hospitals' energy efficiency must be seen as under constant development and re-interpretation.

“…Additionally, several valuable and depleting resources are wasted because of ineffective quality standards, negatively impacting project sustainability and the economy (Siddiqui et al 2016;Shafiei et al 2020). In the era of growing sustainability demands and focus on efficient resource utilization with minimum waste and reduced costs, this paints a negative image of the construction industry, especially in the industry 4.0 times (Khadim et al 2022).…”

Quantifying the cost of quality in construction projects: an insight into the base of the iceberg

Construction projects are complex endeavors where achieving higher quality standards is challenging due to the intrinsic difficulties and dynamic quality management processes. Several quality management techniques exist to overcome quality concerns, such as the cost of quality (COQ). However, implementing COQ in building construction is challenging due to the absence of a comprehensive quality cost-capturing system. Several studies have tried to quantify different quality costs but are mainly focused on visible failure cost—the tip of the iceberg while the base of the iceberg has rarely been explored. This study develops and quantifies each component of the visible and hidden quality costs—the base of the iceberg. Accordingly, a modified prevention, appraisal, and failure model is developed and applied to the primary data of 25 building projects. The findings highlight the unfamiliarity and passive attitude of the involved construction firms towards quality, thus, incurring higher failure costs amounting to over 12% of the total project cost. Most of this cost remains hidden as traditional accounting systems cannot capture it. Such costs must be eliminated by implementing COQ systems as utilized in the current study. Further, a quality costing framework is established for building projects and applied to the local construction industry to reduce construction failures and improve the quality performance of building projects.

“…The integration of circular economy (CE) principles, operations, and business models in the planning, design, construction, operation, maintenance, and deconstruction of buildings, civil engineering, and infrastructure projects provide unprecedented opportunities to decouple construction activities from finite resource consumption and depletion (ARUP, 2016; Circular Construction Economy, 2018; Kubbinga et al, 2018). CE is implemented at the micro (e.g., processes), meso (e.g., buildings), and macro (e.g., organizations, industry) levels of the built environment (Khadim et al, 2022).…”

The transition to a circular economy in the construction industry provides enormous opportunities to decouple construction activities, processes, and practices from finite consumption of natural resources and environmental externalities. Circular construction leverages the interconnected models of narrowing, slowing, and closing resource loops to minimize extractive and wasteful use of natural resources, eliminate waste and pollution from the outset, and retain construction products and materials in use for a longer duration. However, construction practitioners have struggled to implement circular economy principles into construction projects successfully. This study systematically reviewed the critical success factors for implementing circular construction projects. The results revealed 51 critical success factors for circular construction projects, clustered into six typologies: technological (n = 10, Σ = 93, μ = 9.30), supply chain (n = 14, Σ = 84, μ = 6.00), organizational (n = 9, Σ = 82, μ = 9.11), institutional (n = 7, Σ = 43, μ = 6.14), stakeholder success (n = 7, Σ = 73, μ = 10.43), and management success factors (n = 4, Σ = 27, μ = 6.75). A Pareto analysis revealed 30 vital critical success factors for circular construction projects. Thus, the study established the first comprehensive set of critical success strategies for circular construction projects and enriches the knowledge of construction organizations and project team members on how best to implement circular economy principles in construction projects.
