No modern building can function properly if the design program and construction detailing fails to account for the thermal and moisture dynamics of the building envelope and its relation to the internal and external environment. This class will be an in-depth building science investigation of hygro-thermal issues -- including steady-state heat loss, internal and external heat gains, wind & solar radiant impacts, temperature gradients within the building envelope and the effect of relative humidity, air convection and mean radiant temperature on human comfort. This will be the context to explore the often misunderstood issues around indoor and outdoor moisture, moisture migration through the building envelope, moisture storage (or buffering) capacity of materials, effects of relative humidity both inside the building and within the thermal envelope, and moisture control methods that minimize mold, rot, corrosion and warpage while optimizing durability of the structure and human comfort.
