... et al. consider that if the material is, after all, reused after its initial use, the building in which the material is reused should be rewarded with the environmental sav- ings resulting from the avoided processing and manufac- turing of virgin materials. As it is not always clear from previous case studies how environmental crediting of reuse/recycling is actually conducted (Allacker et al., 2014;Aye et al., 2012), EN 15978 (2012) states that benefits from reuse, recovery and recycling (module D in Table 1) should always be reported separately for reliable decision support. According to Allacker et al. (2014), an improvement in the product system model- ling could potentially be to accommodate the average number of times a material or element is recycled or reused, e.g. using the principles in the ILCD handbook. ...

The built environment—with its significant environmental impact and long lifespan—is a key sector in which to implement circular economy principles. So far, however, a coherent framework with circularity indicators has not yet been established.

... For example, in their research on the different types of LCA used to evaluate the effects of buildings on the environment, [19] compared the objectives, methodologies, and findings of three different types of LCA: traditional LCA, Life Cycle Carbon Emissions Assessment (LCCO2A), and Life Cycle Energy Assessment (LCEA). The researchers in [20] concluded that while there are differences in the focus of the LCA, all three are suitable to be used as decisionmaking tools to reduce the environmental impact of buildings. In [57], the authors also explored the use of LCA to aid decisionmaking through software development that can produce building energy audits and examine energy efficiency. ...

This review discusses the unsustainable nature of current production and consumption patterns, particularly in the civil construction sector. To address this, the circular economy model has been proposed as a solution, but the impact reduction of circular strategies (CS) is not well understood. Thus, aligning CS with ecodesign can help achieve sustainable development. We conducted a systematic review of studies on CS and ecodesign strategies (ES) in the built environment, which led us to identify 23 essential strategies, including reuse, recycling, design for disassembly, and design for life extension. This article expands on previous research by identifying 51 CS and ES, some of which are interconnected, and adopting one strategy may benefit another. The authors propose a framework based on the Plan-Do-Check-Act concept to support and manage trade-offs when selecting strategies and to facilitate a collaborative decision-making process. The framework can also help manage the effects of using these strategies on circularity and environmental, social, and economic performance, ultimately improving the construction sector’s environmental performance.
... Demand-side material efficiency measures aim to achieve desired levels of service from smaller cement stocks (Hertwich et al., 2019), including more intensive use (Grubler et al., 2018;Pauliuk et al., 2013) and lifetime extension (Cai et al., 2015;Miller, 2020) of in-use product stock, material-efficient design (Cao et al., 2021;Shanks et al., 2019), material substitution (Churkina et al., 2020;Göswein et al., 2022), as well as reusing building components (Eberhardt et al., 2018;Huuhka et al., 2015) and recycling Xiao et al., 2012) at the end-of-life. More intensive use of residential and commercial buildings by 20% lower area per person could globally reduce 56.8 Gt CO 2 equivalent (CO 2 -eq) greenhouse gas (GHG) emissions from material production during 2020-2060 (Zhong et al., 2021). ...
Demand-side material efficiency strategies could play a key role in decarbonizing the cement cycle as conventional supply-side measures leave little room for improvement and emerging technologies are still in their infancy and expensive. This study quantitatively evaluates CO2 reduction opportunities through China's cement cycle by more intensive use and lifetime extension during 2023-2060. More intensive use and lifetime extension can cumulatively save cement consumption by ~58 gigatons (Gt) during 2023-2060, resulting in CO2 emission reductions of ~33.8 Gt without considering supply-side actions and cement carbonation. If supply-side measures and cement carbonation are considered, China's cement cycle could achieve net-zero CO2 emissions by 2060 or even mid-century. Besides, it is important to assess social implications, opportunities, and challenges of lower per-capita stocks and longer service-life, when we aim to realize these emission reductions. Also, trade-offs between CO2 fluxes should be considered in cement decarbonization road mapping because more intensive use and lifetime extension can lower CO2 uptake by cement carbonation.

: Modular construction (MC) has gained attention due to its potential for fast construction, reduced construction waste, and lower environmental impact while having several other issues on stimulating sustainability. The circular economy (CE) focuses on better resource management through a closed-loop system. Even though MC enhances sustainable practice, several pitfalls barricade sustainability in MC (high initial investment, design consideration, and technology challenges). Nevertheless, the synergy between CE and MC has not been investigated in past studies to address
the issues in MC to achieve sustainability. This study investigates the integration of CE principles in MC to enhance sustainability. This study used a qualitative approach via the Delphi technique by conducting three semi-structured expert interview rounds with the use of a purposive sampling
method. The collected data were analysed using manual content analysis. This study identified nine notable issues in MC to achieve sustainability, and all CE 9-R (rethink, refuse, reduce, reuse, repair, refurbish, remanufacture, recycle, and recover) principles could address those identified
issues. Accordingly, thirty implementation strategies were recognised to fill the gap between the problems in MC and the potential of CE principles to solve the issues. The results provide insights for construction practitioners, policymakers, and researchers on integrating CE principles into MC
processes to achieve sustainability goals. Ultimately, this study highlights the significance of a holistic approach by theoretically combining MC and CE principles as a benchmark for future studies. As a contribution, CE strives to make the planet a safe place to live by combatting resource depletion.

To address Sustainable Development Goals (SDGs) and face climate change effects, it is necessary to adopt multidisciplinary methodologies and strategies for risk prevention and mitigation of the impact in urban contexts. These phenomena represent a risk for cultural heritage conservation, with negative consequences for local economies. To move from the analysis of climate impacts to adaptation measures and governance tools, it is necessary to deal with the different characteristics of the urban context in its physical, historical, cultural, and socio-economic components. The paper focuses on the collaboration between UNIGE Architecture and Design Department (DAD), and Colouree S.r.l. that has developed an analytical platform that uses artificial intelligence, geo-referenced data, and automated analysis to define the characteristics of the urban context. The aim of the research is the identification of parameters and solutions to respond to the effects of climate change in the urban environment, considering risk levels and context settlement; alongside the climatic skills, also the architects’ skills in environmental technologies, urban landscape, and cultural heritage have been given relevance. DAD aims to capitalize on the previous and ongoing experiences of Colouree, offering scientific and methodological support, to reach the definition of a detailed settlement analysis, providing indications on the risks associated with the main predictable effects (extreme weather events, heat island effect, water availability). The expected results will define a methodological structure to create a sensitivity mapping to meteorological phenomena, based on the data support from Colouree towards the carrying capacity of the urban fabric, making information more accessible thanks to the data visualization and web-based mapping, including, among the stakeholders, not only experts but also professionals and citizens.

Smart buildings can be considered the future development direction of constructions: IoT, which extended connections and intelligence to real-life objects, led to a revolution in building practices, making it necessary to obtain edifices equipped with new original features. Seeking to respond to climate-related challenges of the twenty-first century, the technologies triggered by the digital revolution led smart buildings to become the natural evolution of the “sustainable” or NZEB buildings, introducing a series of innovations toward positive changes, continuing the path of hybridization with other disciplines which characterized this digital era. Indeed, the term “smart buildings” conventionally refers to all buildings that show some kind of innovations, concerning technical plants but also building envelope components or the building system as a whole. Besides, it can be said that in the wake of recent directives issued by the EU concerning the Green Deal, the Renovation Wave, and the New European Bauhaus, the technological culture of architecture has evolved, affecting also the aesthetic domain. Therefore, the paper aims to understand the new paradigms of current architecture, analyzing the advantages brought in terms of innovative methods and tools for controlling the quality of construction projects and processes, but also considering new digital techniques for design and representation, smart high-performance materials, adaptive and innovative technologies and/or sensors; thus trying to understand how architectural objects became inspiring examples of the combination of technological innovation and design, and how they can play an important role in terms of environmental sustainability and reduced consumption of resources.

The environmental quality of the modern city is a central issue in the Italian and international design debate. The pandemic and the perspective of a post-pandemic phase have accelerated the inevitable transformation of the living spaces—indoor and outdoor, urban and domestic—bringing out renewed awareness and new quality requirements. The need to achieve results to limit energy consumption, reduce polluting emissions, promote less land consumption, and conditions of urban resilience is becoming gradually urgent, according to European and national strategic, political and regulatory indications. Space quality requirements, which correspond to different conditions of quality of living, are generally identified in the physical and social accessibility of places and dwellings, in the production and availability of energy from renewable sources, in the availability of green public spaces, and in the opportunity to carry out leisure and sports activities. The paper investigates the transformation of public residential neighbourhoods, highlighting urban and technological design opportunities within the paradigm of eco-district and biophilic urbanism. Two case studies within the INA CASA Plan in Reggio Calabria—Sbarre Inferiori and San Brunello—will be the object of analysis and meta-design transformation scenarios to test with green quality requirements. The scenarios aim to explore microclimatic improvements for the districts, the redefinition of outdoor spaces, the implementations of technologies for clean energy production, and the containment of resources consumption. The object of the contribution goes towards principles of health and well-being of the communities, recognising the urban risk factors implicated in the global pandemic and the need to restore the existing building stock and residential estates. Eventually, the paper suggests a framework of actions, green technologies, and design options to manage those environmental concerns.

This work was conducted to design a combined cooling, heating, and power (CCHP) system with photovoltaic energy which provides simultaneous generation of electricity, heat, and cold for a high-rise office building (23 floors) in the city of Mashhad in Iran. Our strategy was to supply load electric, thermal, and refrigeration with the help of solar energy. In addition, its superiority over other systems was evaluated. Analysis and study of solar radiation and the maximum level of solar panels use, according to the architectural plan, were carried out at the project site. The analysis of shadow points, the use of inverters and electrical detectors to increase the maximum solar power, and its cost-effectiveness were carefully studied via PVSOL software. Additionally, the amount of heat, cold, and electricity consumption was accurately calculated according to international standards and utilizing HAP software. The criteria for saving on the initial cost reduction, carbon dioxide emission reduction, operating cost reduction, payback period, revenue, and the minimum life expectancy of the equipment compared to those in other methods were also evaluated. The results obtained from the designed system of simultaneous generation of electricity, heat, and refrigeration, which combines gas microturbines as the primary stimulus, a combination of absorption and compression chiller to provide refrigeration load, a boiler for auxiliary heat load, and a thermal photovoltaic system to produce both electric and thermal loads, were finally revealed. This is believed to be a cost-effective strategy for high-rise residential or commercial buildings with a geographical location like that of Mashhad. Based on the electricity sales to the grid, with the rate of increase in inflation in electricity tariffs, this design in the Mashhad project was estimated to have an annual income of 166.676 thousand dollars. Moreover, the initial capital return period in this project was calculated to be 5.19 years.

One of the conditions toward mitigation and a zero-emission economy is to plan the transition to a sustainable urban energy system. The dimensional and typological variety of urban pattern, and the functional contribution of inhabitants, represent an important potential to reduce energy consumption and climate-changing gases. Despite this evidence, many studies focused on the energy transition have given limited attention to issues of scale, space, and context in urban settings and how they can shape different energy systems. This article deals with renewable energy communities in the urban context and, by presenting some results of research that, through pilot cases in Rome, aims to test mitigation and adaptation solutions in proximity spaces. In particular, it investigates how the different forms of already built urban fabrics, together with social and environmental resources, can influence the form and implementation of the decentralized energy system and vice versa.

The objectives and solutions that become necessary, within the green and digital transition, can radically interfere with existing methods for designing and producing buildings and portions of cities. The “factory” and the “construction site” were one and the same thing, in the production of buildings, up until the seventies of the last century. Following the advent of prefabrication, the factory has gradually been separated from the construction site, to the point where industrial manufacturing now accounts for much of the production value of buildings through the dry-assembly of factory-made products and components. The development of enabling technologies involves knowledge-intensive technologies associated with a high level of research and development, rapid innovation cycles, substantial investment costs and highly qualified jobs. The development of this field could produce a new chain of industrial services for companies based in our country.
