“…Based on the investigation, the index weights were obtained based on the AHP and social WTP, and the LCA-LCC integrated model of the campus building was established. This LCA follows the ISO 14040/44 methodology [39,40], and the LCC refers to the ISO 15686-5 standard and the studies of Sun and Buyle et al [26,41,42].…”

“…The LCC method can be used to evaluate the cost of each phase of the product life cycle. Scholars have carried out building LCC and LCA analyses [26,27]. However, although these studies considered the environmental and economic indexes of buildings, they carried out the evaluation process separately.…”

“…At the same time, regional characteristics should be considered in the selection of building materials to avoid transferring the environmental impact of the construction phase to the construction operation phase. Some scholars have compared building materials [26,[57][58][59][60][61][62][63][64][65], and some scholars have considered the influence of the external environment when evaluating building materials [13,20,21,66] These studies can provide a reference for building designers to choose building materials.…”

The Impact Assessment of Campus Buildings Based on a Life Cycle Assessment–Life Cycle Cost Integrated Model

et al. 2019

The development of higher education has led to an increasing demand for campus buildings. To promote the sustainable development of campus buildings, this paper combines social willingness-to-pay (WTP) with the analytic hierarchy process (AHP) based on the characteristics of Chinese campus buildings to establish a life cycle assessment–life cycle cost (LCA–LCC) integrated model. Based on this model, this paper analyses the teaching building at a university in North China. The results show that the environmental impacts and economic costs are largest in the operation phase of the life cycle, mainly because of the use of electric energy. The environmental impacts and economic costs during the construction phase mainly come from the building material production process (BMPP); in this process, steel is the main source. Throughout the life cycle, abiotic depletion-fossil fuel potential (ADP fossil) and global warming potential (GWP) are the most prominent indexes. Further analysis shows that these two indexes should be the emphases of similar building assessments in the near future. Finally, this study offers suggestions for the proposed buildings and existing buildings based on the prominent problems found in the case study, with the aim to provide reference for the design, construction, and operation management of similar buildings.

“…The studies reviewed show mixed results when it comes to environmental benefits. In some cases it was possible to reduce emissions such as greenhouse gases (GHGs), however in some cases where the circular economy solution involved energy or material requiring an increase in emissions could be observed [123,124]. Furthermore, designing for recycling might not be beneficial if the recycling process itself is too resource demanding [123,125].…”

How Lack of Knowledge and Tools Hinders the Eco-Design of Buildings—A Systematic Review

et al. 2021

The building sector is responsible for extensive resource consumption and waste generation, resulting in high pressure on the environment. A way to potentially mitigate this is by including environmental considerations during building design through the concept known as eco-design. Despite the multiple available approaches of eco-design, the latter is not easily achieved in the building sector. The objective of this paper is to identify and discuss what barriers are currently hindering the implementation of eco-design in the building sector and by which measures building designers can include environmental considerations in their design process. Through a systematic literature review, several barriers to implementation were identified, the main ones being lack of suitable legislation, lack of knowledge amongst building designers, and lack of suitable tools for designers to use. Furthermore, two specific tools were identified that allow the inclusion of environmental consideration in building design, along with nine design strategies providing qualitative guidance on how to potentially minimize energy and material consumption, as well as waste generation. This paper contributes a holistic overview of the major barriers to and existing tools and method for the eco-design of buildings, and provides guidance for both future research and practice.

“…The authors of [42] also acknowledge that the employment of such a reverse logistics system on a wider basis would require investment in local recycling plants and a more in depth investigation utilizing agent based simulation may be required to fully understand the implications of such a system on a country basis. The work of Buyle et al [43] introduces the concept of demountable wall sections and their use in realizing Circular Economy goals within construction. The authors [43] also point to the current lack of quantitative studies assessing the environmental impact of such innovations in the construction industry.…”

Distributed Manufacturing: A New Digital Framework for Sustainable Modular Construction

This paper explores the notion of the modular building construction site as an applied instance of redistributed manufacturing; in so doing, this research seeks to reduce the environmental footprint of building sites, treating them as small digitally connected subunits. In seeking to provide a whole lifecycle appreciation of a construction project, it is noted that the presence of a framework to provide guidance on the consideration of Internet of Things (IoT) data streams and connected construction objects is currently lacking. This paper proposes use of embedded IoT enabled sensing technology within all stages of a modular building lifecycle. An expanded four-phase model of intelligent assets use in construction is proposed along with an outline of the required data flows between the stages of a given building’s entire lifecycle that need to be facilitated for a BIM (Buildings Information Modelling) representation to begin to describe a building project as a sustainable asset within the circular economy. This paper also describes the use of concrete as a modular sensing structure; proposing that health monitoring of the material in situ along with the recoding of environmental factors over time could help to extend the longevity of such structures.
