“…Various database along with several mathematical analysis for summing up overall embodied impacts have been developed and used in previous studies [28]. For instance, Baek et al [2] used inventory prepared by Japan Building Construction; Wang et al [16] used Finnish building classification, while some other studies also used the Bath University Inventory of Carbon and Energy (ICE) to estimate embodied impacts of various building materials [29]. These thus suggest that although all LCA studies are carried out within the framework of ISO standards, simulation, database and analytical tools vary from one study to others.…”

“…Nonetheless, several studies have been carried out on the concept of whole building LCA, with each having different techniques and approaches, as well as varied goal and scope [2,6,7,9,25,26]. Some of the studies address the use of BIM for LCA [16,17].…”

“…The sector has become a major target for environmental improvement as it accounts for more than 40% of total energy consumption and natural resources, with about 33% of global CO2 emission coming from the sector [2] Whilst these alarming figures point out to a need for holistic efforts towards investigating and preventing environmental impacts due to buildings, fortunately, Life Cycle Assessment (LCA), which involves cradle to grave analysis of products, is arguably the best method of evaluating impacts of a particular product on the environment [3] Nonetheless, despite the claim that clear interaction between buildings' lifecycle stages calls for such global methodology like LCA [4], it has been rather applied to other products, with little application to whole building analysis. This is due to the complex nature of buildings' inventory analysis, inadequate inventory data, its long life span, and so on [3,5] Previous research efforts towards estimating building lifecycle impacts have been dedicated to individual buildings in forms of offices, residential and industrial buildings [6,7,8,9].…”

The study aimed at evaluating the extent to which different building materials specifications affect building lifecycle environmental performance, using a Building Information Modelling (BIM) enhanced lifecycle assessment (LCA) methodology. A combination of Revit Architecture which is a BIM based design and analysis tool, an energy simulation tool known as Green Building Studio (GBS) and LCA tool known as ATHENA Impact Estimator were used for the assessment. The LCA was carried out on a life case study of a 2100m 2 one-storey school building as well as its variability analysis, by varying materials specifications in terms of whole building materials. The lifecycle performance of the buildings was primarily evaluated in terms of its Global Warming Potential (GWP) and Health Impacts.The findings of the study show that irrespective of materials used, buildings that are based on renewable energy perform better than those based on fossil fuels over its lifecycle. In terms of building materials, both environmental and health preference of buildings congruently range from timber, brick/block, steel, to Insulated Concrete Foams, in a descending order. The study suggests that as buildings become more energy-efficient during operational stages, serious attention needs to be given to their embodied impacts.The study lay out a methodological framework that could be adopted by industry practitioners in evaluating lifecycle environmental impacts of different BIM modelled materials options at building conception stage. This has the tendency of ensuring that most lifecycle environmentally beneficial materials combinations are selected during specification and construction.

There have been much interest and many efforts to control global warming and reduce greenhouse gas (GHG) emissions throughout the world. Recently, the Republic of Korea has also increased its GHG reduction goal and searched for an implementation plan. In buildings, for example, there have been technology developments and deployment policies to reduce GHG emissions from a life cycle perspective, covering construction materials, building construction, use of buildings and waste disposal. In particular, Korea's Green Standard for Energy and Environmental Design is a certification of environmentally-friendly buildings for their energy saving and reduction of environmental pollution throughout their lives. In fact, the demand and adoption of the certification are rising every year. In construction materials and buildings, as a result, an environmentally-friendly aspect has become crucial. The importance of construction material and building development technologies that can reduce environmental load by diminishing GHG emissions in buildings has emerged. Moreover, there has been a rising necessity to verify the GHG reduction effects of buildings. To assess the reduction of carbon emissions in the buildings built with low-carbon construction technologies and materials, therefore, this study estimated life cycle carbon emissions in reference buildings in which general construction materials are used and in low-carbon buildings. For this, the carbon emissions and their reduction from construction materials (especially concrete) between conventional products and low-carbon materials were estimated, using Life Cycle Assessment (LCA). After estimating carbon emissions from a building life cycle perspective, their reduction in low-carbon buildings compared to the reference buildings was reviewed. The results found that compared to conventional buildings, low-carbon buildings revealed a 25% decrease in carbon emissions in terms of the reduction of Life Cycle CO 2 (LCCO 2 ) per unit area. If diverse production technologies and sales routes are further developed for low-carbon construction materials, carbon emission reduction effects would considerably increase.

“…Second, most of the LCCO2 emissions assessment tools directly use the bill of quantities (BOQ) calculated after the construction of a building begins [35,36]. These constraints complicate assessments made during the early design phase, when LCCO2 emissions can be efficiently reduced [37,38].…”

Abstract:Various tools that assess life cycle CO 2 (LCCO 2 ) emissions are currently being developed throughout the international community. However, most building LCCO 2 emissions assessment tools use a bill of quantities (BOQ), which is calculated after starting a building's construction. Thus, it is difficult to assess building LCCO 2 emissions during the early design phase, even though this capability would be highly effective in reducing LCCO 2 emissions. Therefore, the purpose of this study is to develop a Building Simplified LCCO 2 emissions Assessment Tool (B-SCAT) for application in the early design phase of low-carbon buildings in South Korea, in order to facilitate efficient decision-making. To that end, in the construction stage, the BOQ and building drawings were analyzed, and a database of quantities and equations describing the finished area were conducted for each building element. In the operation stage, the "Korea Energy Census Report" and the "Korea Building Energy Efficiency Rating Certification System" were analyzed, and three kinds of models to evaluate CO 2 emissions were proposed. These analyses enabled the development of the B-SCAT. A case study compared the assessment results performed using the B-SCAT against a conventional assessment model based on the actual BOQ of the evaluated building. These values closely approximated the conventional assessment results with error rates of less than 3%.
