“…These inputs and outputs of mass and energy as a kind of metabolism result in global change presented by air pollution and huge amount of carbon emissions. According to data from the Worldwatch Institute, building sector annually consumes 40% of the stone, sand and gravel, 25% of the timber (Arena and Rosa, 2003). In the member nations of the European Union, buildings consume approximately 50% of the total energy use and contribute almost 50% of the CO 2 emissions released to the Urban building system assumes significant environmental and ecological implications in terms of a contribution of emissions of CO 2 and other greenhouse gases.…”

“…However, the building industry has an even larger energy and environmental footprint as it is one of the human activities with the largest environmental impact. As noted by Dixit et al [5], the construction industry depleted two-fifths of global raw stone, gravel, and sand; one-fourth of virgin wood; and it consumes 40 percent of total energy and 16 percent of fresh water annually [6][7][8][9][10][11][12]. These figures are more or less similar in any developed country.…”

“…By definition, it is the time after which the EROI reaches a value of one and the net energy is equal to zero. Hence, EROI over the life time is: (6) This brings the issue of the lifetime of components [32][33][34] and of the building itself, which are in general poorly defined. To handle this problem, it is often recommended to refer to the norm ISO 15686 Buildings and constructed assets service-life planning [35] or using a 50 years timeframe as a reference for major renovations, since it is acknowledged and used in many studies [36].…”

Abstract:It is often claimed that the cheapest energy is the one you do not need to produce. Nevertheless, this claim could somehow be unsubstantiated. In this article, the authors try to shed some light on this issue by using the concept of energy return on investment (EROI) as a yardstick. This choice brings semantic issues because in this paper the EROI is used in a different context than that of energy production. Indeed, while watts and negawatts share the same physical unit, they are not the same object, which brings some ambiguities in the interpretation of EROI. These are cleared by a refined definition of EROI and an adapted nomenclature. This review studies the research in the energy efficiency of building operation, which is one of the most investigated topics in energy efficiency. This study focuses on the impact of insulation and high efficiency windows as means to exemplify the concepts that are introduced. These results were normalized for climate, life time of the building, and construction material. In many cases, energy efficiency measures imply a very high EROI. Nevertheless, in some circumstances, this is not the case and it might be more profitable to produce the required energy than to try to save it.

“…However, it also responsible for the massive impact on the environment due to natural resource consumption and emission released [1]. Roodman et al [2] suggested that buildings are responsible for world's fresh water withdrawals, wood harvest and material and energy flow that consist of 17%, 25%, and 40%, respectively.…”

Environmental Impact Analysis on Residential Building in Malaysia Using Life Cycle Assessment

Abstract:The building industry has a significant impact on the environment due to massive natural resources and energy it uses throughout its life cycle. This study presents a life cycle assessment of a semi-detached residential building in Malaysia as a case study and assesses the environmental impact under cradle-to-grave which consists of pre-use, construction, use, and end-of-life phases by using Centre of Environmental Science of Leiden University (CML) 2001. Four impact categories were evaluated, namely, acidification, eutrophication, global warming potential (GWP), and ozone layer depletion (ODP). The building operation under use phase contributed the highest global warming potential and acidification with 2.41 × 10 3 kg CO 2 eq and 1.10 × 10 1 kg SO 2 eq, respectively. In the pre-use phase, concrete in the substructure has the most significant overall impact with cement as the primary raw material. The results showed that the residential building in Malaysia has a fairly high impact in GWP but lower in acidification and ODP compared to other studies.
