AAC has manufacturing, embodied energy and greenhouse gas emission impacts similar to those of concrete based on weight, though it is one-quarter to one-fifth that of concrete based on volume. AAC products or building solutions have lower embodied energy per square meter than a concrete alternative. Additionally, AACs much higher insulation value reduces energy consumption required for heating and cooling. AAC possess significant environmental advantages over conventional building materials, such as insulation, longevity, and structural demands in one material. Total energy consumption for producing ACC is less than half of what it takes to produce other building material. AAC helps to reduce at least 30% of environmental waste than traditional concrete. Moreover, a decrease of 50% of greenhouse gas emissions can be achieved. Autoclaved aerated concrete is a better choice for the environment, and meeting the requirement for the construction of green buildings.
