“…Substantial reductions of embodied energy (or carbon) for the use of traditional and locally available building materials were shown, compared to using conventional materials/components in some studies [42,43]. Other studies [44,45] revealed that the use of recycled and reused materials can significantly reduce the embodied energy and carbon emissions in buildings. A study by Maddalena et al [46] indicated that implementation of materials/components with new and innovative technologies helps reduce the embodied carbon of buildings, such as in the form of "green" types of cements and high performance concrete.…”

Implementing China's emission reduction regulations requires a design approach that integrates specific architectural and functional properties of railway stations with low greenhouse gas (GHG) emission. This article analyzes life cycle GHG emissions related to materials production, replacement and operational energy use to identify design drivers and reduction strategies implemented in high-speed railway station (HSRS) buildings. A typical middle-sized HSRS building in a cold climate zone in China is studied. A detailed methodology was proposed for the development and assessment of emission reduction strategies through life cycle assessment (LCA), combined with a building information model (BIM). The results reveal that operational emissions contribute the most to total GHG emissions, constituting approximately 81% while embodied material emissions constitute 19%, with 94 kgCO 2eq /m 2 ·a and 22 kgCO 2eq /m 2 ·a respectively. Optimizing space can reduce operational GHG emissions and service life extension of insulation materials contributes to a 15% reduction in embodied GHG emissions. In all three scenarios, the reduction potentials of space, envelope, and material type optimization were 28.2%, 13.1%, and 3.5% and that measures for reduced life cycle emissions should focus on space in the early stage of building design. This study addresses the research gap by investigating the life cycle GHG emissions from HSRS buildings and reduction strategies to help influence the design decisions of similar projects and large space public buildings which are critical for emission reduction on a larger scale.

“…For example, almost half of the respondents (49.55%) seems to think that EC emission reduction is not that important, while a significant proportion of respondents (37.84%) also do not consider the reduction of OC emission is that important. This finding is however somewhat contradicted with the findings of Kumanayake, Luo [9]. They stated that the priority given to the operational carbon emissions in the past has now shifted more towards the embodied emissions, which is not yet the case with regard to the Sri Lankan construction industry.…”

“…The construction sector has thus become one of the major industries that consume a large number of materials and energy in Sri Lanka. According to Kumanayake, Luo [9], the global construction sector accounts for nearly 40% of the global energy consumption and similarly, the Sri Lankan construction industry accounts for 35% of the national energy consumption in Sri Lanka [9]. The construction sector is also considered as the largest material consumer in the world in 2005 [10] and similarly, the building sector accounts for nearly 50% of the raw material used in Sri Lanka [5].…”

Perception of Embodied Carbon Mitigation Strategies: The Case of Sri Lankan Construction Industry

2019

Whilst operational carbon (OC) emission reduction has received greater attention in the literature, embodied carbon (EC) emission reduction aspect has been largely neglected. This is particularly seen in developing countries. This study assessed the awareness and perception of carbon emission in general and EC emission reduction strategies in particular in the Sri Lankan construction industry. A detailed questionnaire, based on a comprehensive literature review, was developed to assess the awareness and perception of the Sri Lankan construction professionals about global carbon emissions, OC emissions, and EC emissions and carbon mitigation strategies. Based on a sample of 111 professionals in the construction sector, results revealed that the Sri Lankan construction professionals have poor awareness about carbon emission, especially about EC emission and EC mitigation strategies. The results further revealed that they are more concerned about the OC emission reduction than the EC emission reduction. The results suggest that they are basically aware of some basic/conventional mitigation strategies such as better design (low-carbon), an extension of building life and refurbishment of existing buildings and carbon tax, but their awareness of recently introduced micro-level technologies/strategies is significantly poor. Findings are a clear reflection of the current situation in many developing countries with regard to carbon emission and mitigation strategies. It was found that a major reason for low awareness was related to the culture: The majority of the respondents believed that actions to reduce carbon footprint should be initiated and handled by the government and other authorities, but not by construction professionals.

“…Such efforts have focused on the operational environmental impact due to its higher magnitude, which results from the extremely long service life and huge energy demand of buildings compared with general consumer products [15][16][17][18]. In recent years, however, there is an increasing demand for research to intensively evaluate and reduce not only the operational environmental impact but also a building's embodied environmental impact caused by construction materials [19][20][21][22][23][24]. To meet this demand, developed countries such as the US, UK, Germany, and South Korea are evaluating the life cycle embodied environmental impacts associated with construction materials, according to the criteria stipulated in their respective building codes and green building certification systems [8,[25][26][27][28][29][30].…”

Probabilistic Analysis of Major Construction Materials in the Life Cycle Embodied Environmental Cost of Korean Apartment Buildings

This study employs probabilistic analysis to evaluate the life cycle embodied environmental cost of Korean apartment buildings, with a focus on six major construction materials. To this end, the bill of materials was analyzed for 443 Korean apartment buildings according to the type and plan form, and probability density functions (PDFs) were established for the input quantities of the six materials under consideration. Life cycle scenarios were then examined for each material, and their respective life cycle embodied environmental cost factors were established, using a monetary valuation-based damage cost life cycle analysis model. The estimated environmental costs were evaluated by apartment structural type and plan form, based on probability distributions using the Monte Carlo simulation (MCS). Building life cycle embodied environmental cost was estimated between 16.87 USD/m2 and 23.03 USD/m2 (90% confidence interval). Among the structure types analyzed, the highest costs were associated with the wall structure, followed by rigid frame and flat plate structures; at the plan form level, costs followed the sequence plate-type > mixed-type > tower type for a given type of structure.
