“…Within SimaPro, Ecoinvent database (v: 3.0) is used for material modelling, and Environmental Product Declaration (EPD) method has been used as the impact assessment technique. EPD is recommended by EN 15804 with a complete guidline for estimating environmental impacts and has been used in several LCA studies [34,35]. Generally, EPD method is used for creation of environmental impacts declaration and is considered important for the reporting in the product category rules.…”

Abstract:The building sector is one of the crucial stakeholders in the global energy and environmental scenario. Life cycle assessment (LCA) is a tool widely used to evaluate the environmental performance of buildings, materials and activities. Saudi Arabia has a rapidly growing construction sector with over $1 Trillion of ongoing projects. The housing sector, annually needing over 2.32 million new residential units in coming years, is yet to entertain environmental performance of buildings in its list of priorities. The present work undertakes a LCA study of a three-bedroom modern villa located in Dhahran. Providing the structural details of the villa, an account of the 18 main construction materials in terms of quantity and application has been produced. Embodied energy of these materials has been estimated adopting 'cradle-to-gate' approach. Environmental impacts of the materials have been modeled with the help of SimaPro software. The results suggest that concrete accounts for more than 43% of the total embodied energy of the house and is also the predominant material in terms of the overall environmental impacts. Steel is the second most prominent material both in terms of quantity and embodied energy.

“…The temporary materials, including the formwork, floor posts and safety materials used for temporary construction were excluded from the system boundary of this study because all of these were collected after use and reused at the construction sites of other buildings. In addition, accessory materials and work by-products representing less than 0.01% of the total weight of the building materials used for non-residential building construction were excluded from the scope of analysis [32,33]. Examples of the building material unit conversion coefficients used in this study are shown in Table 2 [34].…”

Abstract:In recent years, much research has been conducted internationally to quantitatively evaluate the environmental impact of buildings in order to reduce greenhouse gas emissions and address associated environmental problems. With this in mind, the Green Standard for Energy and Environmental Design (G-SEED) in South Korea was revised in 2016. However, the various possible evaluation methods make it difficult to conduct building life cycle assessment. Moreover, compared to research on residential buildings, life cycle assessment research on non-residential buildings is scarce. Therefore, this study analyzes primary building materials for life cycle assessment of current non-residential buildings to support Korean G-SEED requirements. Design documents for various non-residential buildings are obtained, and the types and numbers of materials used in production are determined. Next, the primary building materials contributing high cumulative weight based on the ISO14040 series of standards are analyzed. We then review the most commonly-used building materials while considering non-residential building types and structures. In addition, construction material reliability is evaluated using the environmental impact unit value. With our results, by suggesting the primary building materials in non-residential buildings, efficient life cycle assessment of non-residential buildings is possible in terms of time and cost.

“…Equations (2)-(4) are the formulas for calculating the private costs for direct construction, annual operation energy, and maintenance costs, respectively. According to Roh et al [41], the six major building materials for which the total contribution exceeded 95% in terms of environmental impact were ready-mixed concrete, rebar, glass, concrete brick, insulation, and gypsum board, which were also included in our 10 major building materials in terms of economic importance.…”

Abstract:In the building construction industry, simultaneous and integrated evaluation of a building's environmental and economic performance in the early planning stage greatly facilitates stakeholders' decision-making for sustainable building construction. This study aimed to develop a streamlined Environmental Life Cycle Costing (ELCC) model for buildings, applicable to the early planning stage of construction projects. To this end, we selected three of the private cost-related life cycle cost categories that are determinants of stakeholders' decision-making in the early planning stage of construction and extracted 10 major building materials that account for over 95% of the total direct construction cost. Then, we developed a streamlined ELCC model for buildings by combining the monetary value-based life cycle analysis model, KOLID (Korean Life Cycle Impact Assessment Method Based on Damage-Oriented Modeling), and the present worth method. Finally, we conducted a case study to empirically verify the applicability of the proposed model.
