This paper aims to (1) identify the causes and impacts of wasted materials, (2) present the results of the field study conducted by the authors to investigate thecauses of material waste in the implementation of building envelopes in Egypt, (3)identify the most important, sub-factors and causes of material waste in theimplementation of building envelopes in Egypt.

(4) Based on expert s' opinions, recommendations are made to avoid wasting materials in implementing buildingenvelopes in Egypt.
