“…Although life cycle management methodology offers different life cycle sustainability assessment (LCSA) tools [35,36] for economic, environmental and social evaluation, it appears that potential added life cycle value is not tangible enough for the industry to comprehend and is thus overlooked in decision-making. A recent study examining both economic and ecological life cycle outcomes of a residential district energy design reveals that cost and emission savings are possible to identify through life cycle assessment methods, however, a life cycle approach is not traditionally utilized in decision-making [37]. In addition, many respondents questioned the ability to justify value for the uncertain future.…”

“…Examples of tools and methods are various life cycle sustainability assessment (LCSA) tools such as life cycle costing (LCC), environmental life cycle assessment (LCA) and social life cycle assessment (SLCA) [35,36]. Life cycle sustainability assessment tools have recently been applied in urban development to identify sustainable design and energy system options [37][38][39]. Through these tools a life cycle perspective in urban development is obtained and informed decisions can be made with a long term sustainable perspective.…”

Urban development bestows a great opportunity to increase sustainability in the built environment as cities are responsible for the majority of environmental impacts. However, the urban development process is fragmented and sub-optimization leads to unsustainable life cycle outcomes. The purpose of this study is to examine the urban development process from a life cycle perspective and identify how different actors understand life cycle management. By utilizing an inductive qualitative research design, 38 in-depth thematic interviews were conducted within the Finnish urban development industry including a case study and independent interviews from different phases of the urban development life cycle. The theoretical perspective is a combination of the ecosystem construct and life cycle management. Results show that there is no clear responsible actor for life cycle management in urban development. All actors claim that there is value to be added, mostly in economic, but also environmental and social terms. This study reveals that investors should be the responsible actor in the urban development process. By claiming responsibility and focusing on life cycle leadership we can improve sustainability in urban development, and respond to the urban sustainability challenge, thus improving the quality of life and welfare in our urban society.

“…Research has shown that this approach can be easily adopted for materials such as concrete [23,24]. Another merit of this method is its utility in evaluation of building [25][26][27][28][29][30] and road construction [31] applications. In view of these merits, this study uses LCA for evaluation of energy consumption, CO 2 emission, and the costs associated with aggregate production and recycling.…”

Steady increase in overexploitation of stone quarries, generation of construction and demolition waste, and costs of preparing extra landfill space have become environmental and waste management challenges in metropolises. In this paper, aggregate production is studied in two scenarios: scenario 1 representing the production of natural aggregates (NA) and scenario 2 representing the production of recycled aggregates (RA). This study consists of two parts. In the first part, the objective is the environmental assessment (energy consumption and CO 2 emission) and economic (cost) evaluation of these two scenarios, which is pursued by life-cycle assessment (LCA) method. In the second part, the results of the first part are used to estimate the optimal combination of production of NA and RA and thereby find an optimal solution (scenario) for a more eco-friendly aggregate production. The defined formulas and relationship are used to develop a model. The results of model validation show that the optimal ratio, in optimal scenario, is 50%. The results show that, compared to scenario 1, optimal scenario improves the energy consumption, CO 2 emissions, and production cost by, respectively, 30%, 36%, and 31%, which demonstrate the effectiveness of this optimization.

“…A life cycle management approach was proposed in this study for large-scale development resorts, where LCC and LCA were linked together in order to create designs that provide environmental sustainability with low operational costs [26]. This study combines LCC and LCA in a case of GDC plant, aiming to classify the actual technologies that could elaborate the maximum sustainable viability and assess the emissions and correspondent mitigation potentials associated with the different technologies [27].…”

Abstract. This paper presents a review of literature relating to Life Cycle Costing (LCC) and Life Cycle Assessments (LCA) in Gas District Cooling plant. The gas district cooling plant uses either vapour compression process or absorption process for the chilled water generation. Both processes have impacts on the economic aspects as well as the contribution to CO2 emissions; thus, integration of the cost and environmental analysis of both processes are necessary. An extensive body of literature exists on both subjects, however, there is very limited number of available literature on the integration of LCC and LCA. The purpose of this review is to find the most suitable optimization model which can integrate the LCC and LCA to provide the best decision in choosing the most cost-effective and environment-friendly system. This review assesses the literature from thirtyfour journals, research papers, and case reports from the year 1995 to 2017. The result of this review shows that the goal programming methodology is the appropriate method for integrating LCC and LCA because it provides the optimal decision in choosing the most cost-effective, environmentfriendly system for the chilled water generation.
