Embodied Energy Calculations:-

1.Total Embodied Energy of Foam Sheet= 17.777 MJ/kg 2.Total Embodied Energy of Acrylic Sheet= 140.7366 MJ/kg 3.Total Embodied Energy of Nylon Rod= 47.704 MJ/kg 4.Total Embodied Energy of L Clamps= 46.818 MJ/kg 5.Total Embodied Energy of Nuts and Bolts= 10.404 MJ/kg Total Embodied Energy= 263.4396 MJ/kg

Alternate Materials:-

Cardboard can be used as an alternative material in place of foam sheet for the Storage unit and the Front panel as cardboard has a lower embodied energy of 35.5 MJ/kg instead of 117 MJ/kg of acrylic sheet.
