“…Another benefit of dimensional coordination and standard materials supplies is the ability to reuse the materials at the end of buildings' life cycle, aligning with the concepts of the circular economy (Molina-Moreno et al, 2017). To reduce waste generated by the construction industry, designers' waste management measures should go beyond immediate construction activities and current use to which the building is put.…”

Notwithstanding that efforts made at the design stage of building construction projects have significant impacts on project outcome, most waste management efforts are usually focussed on construction stage. This is albeit the understanding that construction waste could be significantly reduced through design activities. This study investigates the underlying design measures that are capable of minimising waste generated by construction and demolition activities. Using exploratory sequential mixed method research, the study employs focus group discussions and thematic analysis at the exploratory phase, while questionnaire and structural equation modelling were used at the explanatory stage of the study. The study suggests that construction waste could be significantly reduced by designing for standard materials size and by designing for modern method of construction, thereby minimising waste due to breakage, materials leftover and other major causes of waste. The study further suggests that the design process and design documentation are key underlying measures for mitigating waste in construction projects. This could be enhanced through such critical success factors as a collaborative delivery process, which is characterised by early involvement of contractors and adequate coordination of design between various disciplines involved. Findings of this study would assist designers and other construction stakeholders in understanding the significant measures for designing out waste in construction projects.

“…Another important effect of smart lighting on sustainable development without worsening environmental impact is the increase of productivity in human activities [40], particularly factories [41] and office environments [42]. The economic benefits arising from these productive philosophies are an objective of many matters currently developing within the framework of circular economy, whose coupling with lighting is really fruitful, as shown in several studies to date [43][44][45].…”

In the last decades, lighting has evolved from a branch of engineering ensuring safety and performance in indoor and outdoor installations, to a key discipline interacting with a wide spectrum of fields and having a deep impact on our daily lives. Although this evolution also applies to other areas of knowledge, the special features of lighting make its potential and also its limitations different. It is not the typical field where a well-established mathematical framework allows a departure from well-defined input and identifying clear effects and conclusions. The reason is that lighting is a field dealing with the interaction between a physical phenomenon and a physiological and psychological system, the human being. In addition to the complexity of its basis, the relationship between lighting and sustainability has become stronger in recent years. This relationship is bi-directional in some cases: on one hand, advanced societies require more and more complex lighting installations, which means high energy consumption, use of raw materials, financial costs, manufacturing and maintenance processes, waste and emissions to the atmosphere. On the other hand, good lighting has an impact on issues like productivity, well-being, happiness, disease avoidance, safety, and many other qualitative aspects whose direct or indirect impact on sustainability is remarkable. This work will analyze how lighting can give answers to questions related to sustainability, not only from the classic topics of energy consumption and waste management, but from a wider and global perspective. The results of these works are analyzed, and the basis of the new framework of total lighting, discussed.

“…Due to the increasing concern over these environmental problems, the principles of circular economy (CE) are becoming stronger every year, exerting increasing pressure on decision makers [7][8][9]. In this scenario, engineers are gradually moving from the classical perspective of "manufacture-use-throw" to a circular economy engineering, considering the after-life use of components and systems as technological nutrients [10].…”

The Use of Led Technology and Biomass to Power Public Lighting in a Local Context: The Case of Baeza (Spain)

The impact of public lighting on consumed energy, financial cost, use of raw materials, and the environment is a major concern nowadays. The high amounts of energy needed to satisfy the increasing demands of cities around the world has led researchers to look for alternatives to classical fossil sources, with low implementation in public lighting up to date. In this context, circular economy (CE) proposes a new perspective of engineering based on smart design for the future life of products where even wastes have an added value as technological nutrients for other applications. A convergent consideration of CE and the urgent necessity of more sustainable public lighting leads to this proposal. The ad hoc use of a local biomass plant for powering the public lighting of one small city is considered, and important conclusions reinforcing the link between lighting and CE are presented.
