Building Simplified Life Cycle CO2 Emissions Assessment Tool (B‐SCAT) to Support Low‐Carbon Building Design in South Korea
Sustainability, 2016Co-Authors: Seungjun Roh, Sungho TaeAbstract:Various tools that assess life cycle CO2 (LCCO2) emissions are currently being developed throughout the international community. However, most Building LCCO2 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 LCCO2 emissions during the early design phase, even though this capability would be highly effective in reducing LCCO2 emissions. Therefore, the purpose of this study is to develop a Building Simplified LCCO2 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 CO2 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%

A Study on Life Cycle CO2 Emissions of Low-Carbon Building in South Korea
Sustainability, 2016Co-Authors: Su-hyun Cho, Chang-u ChaeAbstract: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 CO2 (LCCO2) 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

a validated Low Carbon office Building intervention model based on structural equation modelling
Journal of Cleaner Production, 2018Co-Authors: Blessing I Mafimisebi, Keith A Jones, Bahar Sennaroglu, Sunday NwaubaniAbstract:Abstract Building energy performance in existing stocks via facilities management interventions for Low Carbon Building has become expedient and relevant in global climate change discourse. It has raised the consciousness for the need for a unified decision-support model for Facilities Managers and Owners, which could be used for office Buildings across countries in achieving cleaner Building energy production and use. This paper aimed at examining the factors that affect office Building Energy Performance; their interdependencies; and identify the critical path for interventions. It filled this gap by presenting a combination of interrelated processes (operations, tactics, and strategies) needed to improve Building energy performance, reduce costs and greenhouse gas emissions in Buildings for organizations. An online questionnaire survey was used in gathering data on current study model variables from participants of case study office Buildings in Nigeria and the UK. Structural Equation Modelling technique was used to examine the factors that contribute to improving the energy performance of heterogeneous office Buildings in both countries. The result established a strong correlation among observed variables and constructs and high covariance between constructs. This indicates that dependency and interdependence relationships exist amongst constructs, and in between construct and indicators. The finding reveals that an organization needs Sustainability Policy, Facilities Management and Energy Management as a sub-set of Strategic policy incorporated into its core management policy and operations energy management to achieve Low Carbon Building. It also reveals the most critical pathway in the overall model with Strategic Facilities Management discovered to underpin the optimal performance for office Buildings.
