An audit of life cycle energy analyses of buildings

Evaluating the life cycle energy benefits of energy efficiency regulations for buildings

“…This lack of research may be due to the common belief that embodied energy requirements represent only 10-20% of the life cycle energy of a building [21][22][23][24] and are therefore insignificant. However, the majority of existing studies rely on the 'process analysis' technique that can significantly underestimate embodied energy [25].…”

Attributional life cycle assessment of mounted 1.8 kWp monocrystalline photovoltaic system with batteries and comparison with fossil energy production system

“…Therefore, the current study populates the literature from a region where LCA studies are absent. (2) There are also several efforts underway to address the critical need to organize and centralize a worldwide knowledge base of LCI data sources that will ease identification and acquisition of available data [26] -and this is particularly important since many developing countries supply resources to developed countries, thus the need for LCI databases to include products and services from such countries [27]. Therefore when such efforts start in a more concerted manner, the current study would allow the further development of product-specific LCA in Lebanon, since it represents the LCA of the national electricity.…”

Development of a sustainable methodology for life-cycle performance evaluation of solar dryers

“…Some recent studies (Dixit et al, 2014(Dixit et al, , 2012Yung et al, 2013;Zaid and Paul, 2014) have indicated that, with a growing number of energy-efficient processes, the EE forms an increasingly high proportion of the total LC energy consumption in built facilities. In the case of solar dryers, where the majority of the operational energy (OE) comes from renewable sources (e.g.…”
