Proper building envelope design, component detailing, and wall system performance are critical in a durable, energy
efficient building. One of the key aspects of achieving a highly efficient and durable building is the ability to protect the building from unwanted air and water infiltration. This course reviews the necessity and benefits of air, vapor, and moisture barriers, how moisture makes its way into the building envelope, the negative impact it can have on the structure, and different design options to control air leakage and moisture movement to ensure a high performance building.
