“…Previous studies targeting environmental assessments of building sites used differing approaches: Kellenberger and Althaus (2009) mainly consider the necessary auxiliary materials for the construction of a building component. Takano et al (2014) list transportation and logistics expenses as a main driver of potential environmental impacts during the construction of buildings. Wiik et al (2017) consider a relatively broad system boundary of the construction phase and link the main environmental impacts to usage of construction machinery, on-site electricity consumption, transportation, and the general installation of materials.…”

“…As the operational phase of the building constitutes only one part of the whole building life cycle, the consistent reduction of these emissions is not expedient for a holistic sustainable approach. Energy and emissions caused by the manufacturing of the building materials, the construction stage, and the deconstruction of a building are rarely seen in the sustainability assessment (Takano et al, 2014). Dependent on the energy standard of the building and the duration of the operational phase the shares of the embodied energy gain in importance compared to the energy consumption during the operational phase.…”

The building sector is key to achieving global sustainability targets due to its significant resource consumption, associated emissions, and waste generation. Life cycle assessment (LCA) evaluates the environmental quality of buildings to identify improvement possibilities. However, current research activities limit their focus on a few life cycle phases, while the construction phase receives none to little attention. At the heart of the problem lies the lack of information about on-site processes and the lack of tools to evaluate the environmental quality of construction processes. The authors developed a conceptual framework to assess this aspect using an interdisciplinary approach. The proposed solution is based on two main methods, namely LCA and Takt Planning (TP).Based on literature research we identified the main categories for environmentally relevant in-and outputs of construction processes. This allows a structured, standardized, and scalable assessment of each single process step from an environmental perspective We anticipate this method to be a starting point for a holistic sustainability approach for construction process assessment. Further development of this framework aims to broaden the current environmental evaluation in the building sector and to improve both, the construction process and the building product from an environmental point of view.

“…However, the energy and fuel used on site during construction were excluded, as their emissions are minimal compared with the emissions of the entire building's life cycle. For example, the construction processes contribute to only about 2-5% of the total emissions (except refurbishments, demolition, and waste treatment) [28,50]. Taking into account the quantity and environmental profile, this study initially focused on three major materials, namely concrete, steel, and timber as they are the dominant contributors of embodied carbon of a housing block [51].…”

Despite the fact that many novel initiatives have been put forward to reduce the carbon emissions of buildings, there is still a lack of comprehensive investigation in analyzing a buildings’ life cycle greenhouse gas (GHG) emissions, especially in high-density cities. In addition, no studies have made attempt to evaluate GHG emissions by considering the whole life cycle of buildings in Hong Kong. Knowledge of localized emission at different stages is critical, as the emission varies greatly in different regions. Without a reliable emission level of buildings, it is difficult to determine which aspects can reduce the life cycle GHG emissions. Therefore, this study aims to evaluate the life cycle GHG emissions of buildings by considering “cradle-to-grave” system boundary, with a case-specific high-rise residential housing block as a representative public housing development in Hong Kong. The results demonstrated that the life cycle GHG emission of the case residential building was 4980 kg CO2e/m2. The analysis showed that the majority (over 86%) of the emission resulted from the use phase of the building including renovation. The results and analysis presented in this study can help the relevant parties in designing low carbon and sustainable residential development in the future.

“…For example, transportation, construction machinery, waste production and energy consumption during building construction phase, have significant environmental costs, indicating that any improvements in these parts could be priority marks for reducing GHG emissions during the construction phase, as well as the overall life cycle impact of a building. [3] shows that the construction stage accounts for 20-30% of the initial embodied emissions and 6-10% of the total emissions of the life cycle stages of buildings.…”

Being one of the primary contributors to global GHG emissions, the construction industry has been the focus of many recent studies. The process of manufacturing and transporting of building materials, and installing and constructing of buildings consumes great energy and emits a large quantity of greenhouse gas. This study identifies the sources of GHG emissions during building construction phase and estimates the GHG emissions from those sources for a case building in Bangladesh, following the process-based methodology. The results for the case building show that about 98.38% of total emissions are due to the manufacture and transportation of building materials, 1.31% is due to energy consumption during the construction period and only 0.31% are due to waste disposals, while concrete and brickworks are the most contributing materials to the GHG emissions, about 35.22% and 48.67% respectively. This study has been conducted in Bangladesh as the concern for GHG emissions in building construction is not satisfactory here yet. It also proposes a set of unique strategies, such as, using recycled building materials, especially recycled steel, as well as, transporting building materials by sea, re-using wooden waste materials and using hardwood plywood in place of non-load bearing brick walls and demonstrates the reduction of GHG emission numerically by applying these strategies, which are the originalities of this study.
