Hi Ahmed, your question seems to be incomplete. you are talking about energy input and output but what is your project name? how many processes or operations do you have? do you want to perform life cycle assessment of what?
Clarify your main problem.
I need to calculate CO2 emissions form Life Cycle Assessment of Residential Building.
LCA has 5 stages:
1- Raw Material Extraction and transformation it to Factories whcih manufacturing the construction material.
2- Transformation the construction material to the building site.
3- Construction the building.
4- Operation and Maintenance.
5- Demotion and End of building life.
Finally the recycle building.
These stages called Cradle to Grave.
I am so sorry for your inconvenience,
Ahmed Monteleb
First your system should be defined clearly. Inputs and outputs should be determined. system boundry should be drawn precisely. Foreground and background system need to be defined. Also, assessing the appropriate functional unit is the next stage and one of the most important part of your study. Then you can follow the carbon footprint in Residential building.
I know that Egypt do not have the input-output analysis tables, can i find the general tables and what is the capability to use it in my case study in Egypt?
If no, what is the suitable tool to calculate CO2 emissions from building LCA?
Thanks,
You need to provide initial data which are fully related to your project. i.e. how much electricity is used? how much iron, glass, wood, etc. are used. When the stage of inventory is completed some softwares can be applied. In fact in the case you do not have enough database you can use these softwares to model your project. I suggest simapro however there are some controversy about application of these softwares.
because it works like a black box. It is a big question whether or not its database completely is trustable and so forth. But forget about this negative aspect of this software. It has been used in different studies. I have also applied it in my several studies.
Hi Ahmed
