ACI CODE-122.1-21 (IN-LB) PDF Download

ACI CODE-122.1-21 (IN-LB) is a standard that provides guidelines for designing and constructing buildings with effective thermal bridge mitigation. The standard specifically focuses on buildings that have concrete or masonry walls, masonry veneer (including veneer attached to frame walls), balconies, and components that pass through the building envelope.

The purpose of the code is to reduce heat transfer through thermal bridges in building envelopes, which can decrease a building's energy efficiency and increase energy consumption. The requirements outlined in the code aim to improve the thermal performance of commercial and mid- to high-rise residential buildings that use electricity or fossil fuels.

Additionally, the code provides criteria for addressing metal thermal bridges in these types of buildings. It is designed to be used in conjunction with other applicable energy codes and standards, ensuring that thermal bridge mitigation strategies align with overall energy efficiency goals.
