Thermal Efficiency - Aercon AAC Autoclaved Aerated Concrete

To meet the thermal efficiency requirements of that code, the EPI must not exceed a value of 100. The lower the EPI for a building, the more energy efficient and, therefore, the lower the energy costs for heating and cooling. This study calculated the EPI for a building which utilized 8-inch thick AERCON block for the exterior walls.
