“…In previous studies, the possibility of reducing CO 2 emissions by up to 30% during the construction phase was demonstrated through the selection of low environmental impact materials (González and García Navarro, 2006) and the environmental impacts of CO 2 emissions in building construction phase of single family detached houses in Spain were analyzed (Pacheco-Torres et al, 2014). Many studies have emphasized the dominance of the operation stage in life cycle carbon emissions assessment irrespective of the country in which the study was based (Kofoworola and Gheewala, 2008;Varun et al, 2012;Atmaca A and Atmaca N, 2015;Zhang et al, 2016). The carbon emissions at the material production stage have also been found to be significant by many researchers (Varun et al, 2012;Zhang et al, 2016).…”

The carbon emissions at the material production stage have also been found to be significant by many researchers (Varun et al, 2012;Zhang et al, 2016). By investigating CO 2 emissions of 78 office buildings in China during the pre-use stage, it was found that material production accounted for 75% of the total CO 2 emissions and steel, concrete, mortar and wall materials made up over 80% of the emissions of material production stage (Luo et al, 2015).…”

“…Most of the past research on building energy and carbon emissions has focused on developed and temperate climate countries and only a few examples from developing tropical countries exist (Kofoworola and Gheewala, 2008;Ramesh et al, 2012;Varun et al, 2012;Paulsen and Sposto, 2013;Pinky Devi and Palaniappan, 2014;Wen et al, 2015). The linkage between building design, energy use and carbon emissions is dependent on and sensitive to climate and the socio-demographic characteristics that are geographically and culturally variable (Atmaca A and Atmaca N, 2015).…”

“…Only a few studies can be found for university buildings which have special characteristics; usually these are multi-purpose buildings consisting of offices, class rooms, laboratories and in some cases residential facilities. Therefore their energy and carbon emission characteristics are found to be complex and differ substantially from case to case (Scheuer et al, 2003;Varun et al, 2012;Wu et al, 2012;Biswas, 2014).…”

Buildings are known to significantly affect the global carbon emissions throughout their life cycle. To mitigate carbon emissions, investigation of the current performance of buildings with regard to energy consumption and carbon emissions is necessary. This paper presents a process-based life cycle assessment methodology for assessing carbon emissions of buildings, using a multistorey reinforced concrete building in a Sri Lankan university as a case study. The entire cradle-to-grave building life cycle was assessed and the life span of the building was assumed as 50 years. The results provide evidence of the significance of operation and material production stages, which contributed to the total carbon emissions by 63.22% and 31.59% respectively. Between them, the main structural materials, concrete and reinforcement steel made up 61.91% of the total carbon emitted at the material production stage. The life cycle carbon emissions of the building were found to be 31.81 kg$m-2 CO 2 per year, which is comparable with the values obtained in similar studies found in the literature. In minimizing the life cycle carbon emissions, the importance of identifying control measures for both building operation and material production at the early design stage were emphasized. Although the other life cycle stages only contributed to about 5.19% of the life cycle carbon emissions, they should also receive attention when formulating control strategies. Some of the recommended strategies are introducing energy efficiency measures in building design and operation, using renewable energy for building operation and manufacturing of materials, identifying designs that can save mass material quantities, using alternative materials that are locally available in Sri Lanka and implementing material reuse and recycling. This study is one of the first to undertake a life cycle carbon emissions assessment for a building in the Sri Lankan context, with the hope of facilitating environmentallyfriendly buildings and promoting sustainable construction practices in the country.

“…LCA is a well-known technique for evaluation of ecological impact quantitatively. Varun et al investigated that the life cycle energy and GHG emissions for a three storey institutional building are 6.67 GJ/m 2 and 0.45 tCO2eq/m 2 , respectively (Varun et al, 2012). Ramesh et al conducted a review of the life cycle energy (LCE) analysis of buildings (both residential & commercial) and suggest that operational phase (80-90%) contribute a significant role in total building's energy demand (Ramesh et al, 2010).…”

Buildings are responsible for significant natural resource consumption, waste generation, and environmental pollution. Building impacts are generally assessed through life cycle analysis (LCA). This study integrates LCA with the Ecological Footprint indicator for the assessment of a building's impact on the planet. In order to determine ecological impact of a building, a methodology has been established for estimation of Life Cycle Ecological Footprint (LCEFtotal) of the building, as well as to assess its impact due to resource consumption (energy, water, building materials, manpower etc.) and waste assimilation over the lifecycle. For an academic building located in India taken as a case study, the LCEFtotal is found to be 4397.03 gha and the LCEFtotal per unit floor area is 0.60 gha/m 2. The average annual Ecological Footprint (EFavg) of the academic building is 73.28 gha/yr that is approximately 20 times more than the actual physical land of the campus. The average annual Ecological Footprint per student (EFavg/student) of the academic building is 0.045 gha/yr/student. If annual grid electricity consumption of the building is replaced by the grid-connected rooftop photovoltaic (GRSPV) system in the ratios of 100%, 75%, 50% and 25%, it can reduce up to 61%, 54%, 31%, and 15% of the total LCEFtotal of the academic building, respectively.
