“…Not all the studies reported the method applied for the characterisation factors, beingCML [31] and TRACI [32]themost commonly applied ones. Finally, it should be noted that some studies [4,5,16,17] applied Ecoindicator'99 [33] as the end-point LCIA method, which is not consistent with EN 15978 requirements [6].…”

“…For instance, [11] applied their workto a building according to two standards, namely the Swedish building code of 2012 and the Swedish Passivhaus 2012 criteria. The authors in [13] applied their methodology to a low-rise office building in the USA, [17] to two single-family houses in Poland, and [16] to a single low-energy building that contained 19 flats in Belgium.…”

“…Regarding the life cycle inventory (LCI) data source, Ecoinvent [22] was the most commonly used database [10][11][12]14], while BESLCI [21] was used in [9] and Athena IE [24] in [13]. It is worth noting that a considerable number of studies [4,5,16,17] did not specify the source for the LCI model. As for the life cycle impact assessment (LCIA) stage, almost all the reviewed studies considered mid-point LCIA methods to present the environmental results.…”

“…However, their environmental or cost effect on buildings' life cycle energy demand is an emerging research area promoted by recent changes within the regulatory framework of buildings [6][7][8]. By way of example, [4,5,[9][10][11][12][13][14][15][16], they focus on their environmental performance, while [4,5,17] also focusing on their cost performance. However, and in agreement with the conclusions from [18], the insulation thickness calculated by applying energy or environmental optimisation criteria give, in some cases, results that are 10-fold higher than those obtained using economic criteria.…”

Thermal insulation materials play an important role in the challenge of nearly zero-energy buildings thanks to their potential in reducing building's energy demand and carbon emissions. However, increasing the thickness of the insulation material in the building's envelope has implications from the energy, environmental and economic viewpoints. In this context, efforts should be made to optimise insulation thickness to balance all these aspects.This study presents a methodology to analyse optimum insulation material for the building's envelope (roof, façade and floor) and its thickness to achieve energy demand reductions in the operation phase of the building, which is based on the Life Cycle Assessment and Life Cycle Costing methodologies to integrate both environmental and economic aspects, respectively. The system boundary includes the life cycle stages of product and use defined by recent European standards. A selection of eleven alternative insulation materials, both conventional and emerging ones based on natural products, were chosen to conduct the study. After applying the methodology to a single-family house in Spain and performing a sensitivity analysis, the results revealed that sheep wool and recycled cotton, jointly with traditionally used mineral and glass wool, should be promoted in the construction industry as they offer the highest eco-efficient performance among the analysed insulation materials. Reductions of up to 40% in energy demand compared to regulations standards can be achieved in theeco-efficiency context. Keywords: optimuminsulation thickness; eco-efficiency; life cycle assessment; life cycle cost; energy demand Highlights• Optimising insulation thickness for the building's envelope • Eco-efficiency analysis of life cycle and cost assessment • Sensitivity analysis by varying the building's energy demand scenarios • Emerging naturally-based insulation materials were the most eco-efficient 3

An Inquiry into the Life Cycle of Systems of Inner Walls: Comparison of Masonry and Drywall

et al. 2015

View full text Add to dashboard Cite

Life Cycle Assessment is a methodology that investigates impacts linked to a product or service during its entire life cycle. Life Cycle Assessment studies investigate processes and sub-processes in a fragmented way to ascertain their inputs, outputs and emissions and get an overview of the generating sources of their environmental loads. The lifecycle concept involves all direct and indirect processes of the studied object. This article aims to model the material flows in the masonry and drywall systems and internal walls in a Brazilian scenario, and calculate the climate change impacts generated by the transport of the component materials of the systems. Internal walls of a residential dwelling in Rio de Janeiro are analyzed from a qualitative inventory of all life cycles with an analysis of material flows, based on technical and academic literature. All Life Cycle Impact Assessment of the systems is carried out with international data from the database, and using the IPCC2013 method for climate change impacts. This study disregards the refurbishment and possible extensions within the use phase. Thus, the inventory identifies weaknesses of the systems while the impact assessment validates the results. This study allows us a complete understanding about the inner walls systems in the Brazilian scenario, evidencing its main weaknesses and subsidizes decision-making for the industry and for planning of the new buildings.
