From aforementioned, although the input-output tables are a detailed approach and can provide energy requirements by industry, it requires the existence of an energy input-output table, which does not exist for Egypt [17]. In addition, this approach does not provide straightforward price elasticities. Therefore, it would not be feasible to use it for the evaluation of life cycle impact assessment of buildings. And by extension, it would not be feasible to use the HLCA because it depends on the I-O LCA in Egypt.

Table 1: Some International Databases and Tools of Life-Cycle Assessment [1] Impact Factor CC): 1.3268 - This article can be downloaded from www.impactjournals.us years of data collected by research companies or governments. Johnson et al. [29] emphasized that there are specific calculation procedures for performing an LCA inventory analysis by hand, however these procedures have been mostly superseded by computer software. Programs such as SimaPro (www.pre.nl/simapro) and GaBi (www.gabi-software.com), both developed in Europe, allow users to create an inventory using information collected by the user or taken from databases included in the software. Typical databases include those developed by the software companies, as well as databases like Ecoinvent which have been compiled from vears of data collected bv research companies or governments.

Development Egyptian Tool to Estimate Carbon Emissions from LCA of Building Materials (ECE-LCA Tool) From the previous tables which shown that Egypt do not have tool to estimate carbon emissions from building LCA, ECE-LCA must include a building's life cycle, and be devised to permit input and output of Egyptian LCI database for the respective stages of this life cycle. Furthermore, it is necessary to allow comparison between alternatives, and to show the results of analyses in a quantitative format of CO2 emissions. The research will study BeCost tool to take advantage from it, furthermore to be a guide in creating ECE-LCA Tool. ECE-LCA Tool should have these input to developed; Type of usage, Location, Structure, Building dimension, Total area and volume of building, Height of area, Life span of building. Be-Cost is a www-based tool for life cycle assessment of building structures and for the whole building, Figure 5. [30] The program includes: From the previous tables which shown that Egypt do not have tool to estimate carbon emissions from building
