“…The complexity and relative novelty of the topic has resulted in several published works focusing largely on studying the existing literature. For instance, Zeng and Chini mapped out existing research in a "knowledge map" that enables better understanding of the work done thus far, with the results being the identification of key areas for future work in the field: technology, industry, and optimization [7]. Other work has explored the literature to better comprehend components that need to be accounted for in the pursuit of more accurate embodied energy calculation.…”

There is an increasing demand for the decarbonization of existing buildings. The development of standardized calculation methods has simplified calculation processes and enabled wider engagement with the topic. As the industry advances, optimization and accounting for regional differences will increase in importance. This paper reviews the key drivers in the field, both locally and internationally, and proposes a performance-based evaluation method specific to local construction in Egypt. The aim of the method is to assist in the renovation of existing buildings by guiding the decision-making process through the proposed evaluation framework. A local case study of an existing multi-story apartment building was used to create a baseline for typical local multi-story residential buildings and demonstrated the effectiveness of the proposed evaluation method. This framework provides the owners of buildings with a decision-making process by which carbon impacts associated with future renovations and operations of existing buildings can be minimized.

“…It is important to note that assessing carbon emissions for all construction materials used in a building accordingly in the G-SEED certification process is difficult since more than 1000 different construction materials are typically used in the construction of a new building. Therefore, this study applied a streamlined LCA approach, which considered primary construction materials with high carbon emissions among all the materials used in a building, and analyzed the life cycle scenarios of The embodied carbon emissions refer to the total of carbon emissions arising from the construction material production, construction material transportation, building construction, building maintenance, building dissolution, waste transportation, incineration, and landfill processes [39][40][41][42][43][44][45][46], as shown in Equation 3. On the other hand, the operational emissions refer to carbon emissions that arise from energy consumed by the operational stages during the service life of a building, as shown in Equation 4.…”

Developing a Green Building Index (GBI) Certification System to Effectively Reduce Carbon Emissions in South Korea’s Building Industry

The building industry is currently strengthening the building life cycle assessment (LCA) criteria of the green building certification system to encourage carbon emission reduction. However, the voluntary approach of the LCA criteria does not provide sufficient incentive to effectively drive green building construction. Furthermore, additional costs associated with green building construction are not given enough weightage, thus hampering the incorporation of green building technologies. This study developed a Green Building Index (GBI) Certification System to effectively reduce carbon emissions in South Korea's building industry. Consequently, the assessment areas for green buildings were divided into a carbon emission index, a building habitability index, and a carbon economic index, and assessment methods were suggested for each area. In addition, eco-efficiency, which represents an environmental value, was incorporated into the three indices from the perspective of green building certification and used to estimate a GBI that represents overall building sustainability. This GBI was then integrated into an overall GBI Certification System, and a case study was used to evaluate its applicability. The results indicate the validity of the proposed GBI Certification System, which promotes voluntary carbon emission reduction by evaluating cost effectiveness based on life cycle carbon emissions and carbon economic efficiency.

“…Some of the previous studies on the analysis of EEIs are important in terms of their approach, methodology, and case studies [27][28][29][30][31][32][33]. Because they mostly analyzed only carbon emissions during the production stage of the building materials, their use has been limited.…”

Analysis of Embodied Environmental Impacts of Korean Apartment Buildings Considering Major Building Materials

Because the reduction in environmental impacts (EIs) of buildings using life-cycle assessment (LCA) has been emphasized as a practical strategy for the sustainable development of the construction industry, studies are required to analyze not only the operational environmental impacts (OEIs) of buildings, but also the embodied environmental impacts (EEIs) of building materials. This study aims to analyze the EEIs of Korean apartment buildings on the basis of major building materials as part of research with the goal of reducing the EIs of buildings. For this purpose, six types of building materials (ready-mixed concrete, reinforcement steel, concrete bricks, glass, insulation, and gypsum) for apartment buildings were selected as major building materials, and their inputs per unit area according to the structure types and plans of apartment buildings were derived by analyzing the design and bills of materials of 443 apartment buildings constructed in South Korea. In addition, a life-cycle scenario including the production, construction, maintenance, and end-of-life stage was constructed for each major building material. The EEIs of the apartment buildings were quantitatively assessed by applying the life-cycle inventory database (LCI DB) and the Korean life-cycle impact assessment (LCIA) method based on damage-oriented modeling (KOLID), and the results were analyzed.
