“…This could be as a result of the fact that sustainability has not be accorded the needed attention in the training of the architect [9]. A recent Nigerian study by [10][11] revealed that carbon emission intensity of buildings in Nigeria is significantly high related to the values obtained from developed countries. Udomiaye et al, [11] added that the high emission intensity was traced to high volume of non-structural concrete elements such as concrete fascia, non-load bearing columns and concrete parapets.…”

Moreover, the paucity of knowledge that exists with respect to what makes sustainable architecture or green design, how emissions from built environments can be mitigated and how to assess environmental sustainability need to be filled.…”

Sustainable architecture searches for methods to lessen the adverse environmental burdens of buildings by efficiently and moderately using materials, energy and space. Ensuring sustainable development in multiple dimensions requires an essential factor such as sustainable architectural practice that inculcates assessment framework. Life Cycle Energy Assessment (LCEA) is a key component of Life Cycle Assessment (LCA) in which energy use at different life cycle stage of buildings is the only parameter analysed. In developing countries, defining sustainable architecture and environmental sustainability assessment in buildings remains a herculean task. The aim of the study was to examine the theoretical challenges associated with defining what we mean by calling a building "green" or sustainable architectural design and a post-positivism viewpoint on sustainability assessment of architectural design. The objectives are to review the criteria for sustainable architecture and conduct an LCEA of an existing residential apartment building in Abakaliki-Nigeria, using process-based Life Cycle Energy Assessment. The embodied energy intensity was found to be high at 6.10GJ/M 2 , while cement-based component was 8.8% by mass but accounted for 67.6% of the embodied energy. Consequently, it is imperative to carry out LCEA at the early stage of design and employ strategies to reduce embodied energy instead of focusing only on lessening the operational energy. Environmental and energy efficiency approaches should be prioritized on a life cycle energy basis.
