Building envelope requirements refer to the mandatory regulations and standards that apply to the physical barriers that divide the interior and exterior environments of a building. These requirements aim to enhance energy efficiency, improve indoor air quality, and reduce the risk of moisture infiltration or structural damage. Some of the typical building envelope requirements include:
1. Adequate insulation and ventilation to prevent heat loss or gain
2. Proper air sealing to minimize air leakage and ensure consistent temperature and humidity levels
3. Use of high-performance windows and doors to control solar gain and heat transfer
4. Compliance with energy codes that set minimum requirements for the thermal performance of exterior walls, roofs, and foundations
5. Installation of weather-resistant barriers, flashing, and drainage systems to prevent water infiltration and damage to the building structure
6. Implementation of measures to mitigate the risk of air and moisture infiltration such as vapor retarders, sealants, and tape.
These building envelope requirements may vary depending on the climate zone, building type, and local building codes and regulations.
