Reinforced concrete skeleton is the most commonly used structural system for construction worldwide. However, it is not the most eco-friendly alternative; therefore, finding innovative green alternatives is a necessity amidst the climate change effects the world is currently facing. In addition, construction costs are increasing making it a challenging to fund housing projects for the low-income. Accordingly, four building alternatives were examined for constructing a single-story building of a small room to determine the most eco-friendly and cost-effective construction materials. Alternative 1 is cement bricks masonry parabolic vault, alternative 2 is cement masonry units for walls and structurally insulated panels (SIPs) for roof, alternative 3 is SIPs for the walls and the roof, and alternative 4 is the typical reinforced concrete skeleton with cement bricks for masonry. Each alternative is investigated for its structural integrity and soundness, carbon emissions per unit area, estimated construction cost and building envelope conductance. It was determined that alternative 3 is the most environmentally friendly as it only emits 66.29 kgCO2e/m2, while alternative 1 was the least, emitting 753.49 kgCO2e/m2. However, alternative 1 is shown to have the least construction cost of 1730.78 EGP/m2, while alternative 3 has the highest cost of 6150 EGP/m2. Finally, in terms of thermal conductance, alternative 1 had the highest of 12.35 W/K.m2 while alternative 3 had the lowest of only 0.59 W/K.m2

摘要

Reinforced concrete skeleton is the most commonly used structural system for construction worldwide. However, it is not the most eco-friendly alternative; therefore, finding innovative green alternatives is a necessity amidst the climate change effects the world is currently facing. In addition, construction costs are increasing making it a challenging to fund housing projects for the low-income. Accordingly, four building alternatives were examined for constructing a single-story building of a small room to determine the most eco-friendly and cost-effective construction materials. Alternative 1 is cement bricks masonry parabolic vault, alternative 2 is cement masonry units for walls and structurally insulated panels (SIPs) for roof, alternative 3 is SIPs for the walls and the roof, and alternative 4 is the typical reinforced concrete skeleton with cement bricks for masonry. Each alternative is investigated for its structural integrity and soundness, carbon emissions per unit area, estimated construction cost and building envelope conductance. It was determined that alternative 3 is the most environmentally friendly as it only emits 66.29 kgCO2e/m2, while alternative 1 was the least, emitting 753.49 kgCO2e/m2. However, alternative 1 is shown to have the least construction cost of 1730.78 EGP/m2, while alternative 3 has the highest cost of 6150 EGP/m2. Finally, in terms of thermal conductance, alternative 1 had the highest of 12.35 W/K.m2 while alternative 3 had the lowest of only 0.59 W/K.m2
