A State-of-the-Art Review of the Implementation of Continuous Insulation in US Buildings Based on Energy Codes

The building sector in the US accounts for approximately 29% of total energy consumption and about 40% of CO2 emissions. An essential approach to reduce energy usage in buildings and meet decarbonization goals involves implementing continuous insulation (CI) in alignment with international codes. Therefore, this research places its primary emphasis on conducting an extensive review of existing literature, exploring the importance and obstacles related to CI utilization, and tracing the development of CI within the existing international codes across all US states. This evolution reflects its transformation from a simple suggestion to a mandatory building construction standard.
