In the current context of the necessary sustainability transition of the built environment, it is widely recognized that buildings are a major contributor to the energy consumption of fossil fuels and the emission of CO. Most of the debates, policies and research are however dedicated to the sole construction of new very efficient (up to zero-energy) building, neglecting the potential of actions on the existing building stock. In this context, we argue that LCA tools are of a huge interest to objectivise the need to refurbish old buildings, in order to increase their energy efficiency and extend their life span, and to compare this strategy to the demolition/reconstruction of buildings. To achieve this aim, this paper aims at updating an existing tool that enables to carry out the life cycle assessment of buildings, by taking into account demolition and construction phases. Then, the tool is applied to one case study of the low-energy refurbishment of a public office building in Brussels, to compare the impacts of the complete demolition followed by a complete reconstruction (rebuild project) to the retrofitting of the existing building (retrofit project). Our main findings confirm the huge impact of the use phase, highlight the impact (energy and CO emissions) of the construction and demolition phases and show that the in-depth renovation of this building leads to lower environmental indicators compared to its full reconstruction. The tool and results provided in this paper support the development of policies in favour of the retrofitting of the existing building stock and highlight the importance of including the whole life cycle of the building in the analysis.

“…IMACC is a model that assesses the cost and CO2 emission of the various structural-design alternatives proposed in the structural-design process. To develop the IMACC, a standard on assessing the cost and CO2 emission generated in the construction stage was proposed, along with the CO2 emission factors in the structural materials, based on such materials' strengths [14].…”

Abstract:As argued by 'Declaration of Concrete Environment (2010)' of Korea and 'Declaration of Asian Concrete Environment (2011)' of six Asian countries, concrete as a single material has lately shown extremely large impact on environmental issues such as climate change. Assessment of environmental impact from concrete material and production has considerable importance. Concrete is a major material used in the construction industry that emits a large amount of substances with environmental impacts during its life cycle. Accordingly, technologies for the reduction in and assessment of the environmental impact of concrete from the perspective of Life Cycle Assessment must be developed. At present, the studies in relation to greenhouse gas emission from concrete are being carried out globally as a countermeasure against climate change. In this study, CO2 reduction concrete mix design algorithm was designed using correlation analyses, and its carbon emission and cost reduction performances were assessed. Using correlation analyses, the concrete strength, water/cement (w/c) ratio and fine aggregate/total aggregate (s/a) ratio, and CO2 emissions were identified as major variables of concrete mix design that influenced other variables. Also, this study aims to evaluate the CO2 emission reduction performance of the algorithm-deduced CO2 reduction concrete mix design, and therefore, the CO2 emissions of the CO2 reduction concrete mix design are compared with those of the actual concrete mix design applied to the construction of the office building A in South Korea.

“…Herein the economic cost and ecological impact are calculated in parallel without actual integration of the results. Secondly, compared integration, where every possible scenario is compared to a base case, is discussed in [11,12,13]. Thirdly, partial integration is defined as a complete integration for one or more specific items (i.e.…”

The increasing awareness of environmental impacts along with the possible ecological impact reductions due to good maintenance leads to a demand for research about integration of ecological aspects in maintenance management. This paper investigates this by developing a framework that integrates ecological aspects in maintenance management. As such, an economic and ecological analysis tool, covering several maintenance policies, is developed. Based on the presented models it is possible to determine the optimal maintenance interval considering an economic, ecological and integrated optimum. Finally, the developed model is verified and validated by application to a case study of a cutting tool of a turning machine.
