DER Measures Specification – Being Specific
§ Communicate the functional intent Ø Very difficult to anticipate every condition Ø Empowers person in the field:
Water control è down and out Air flow control è make connections air tight Thermal control è avoid putting bridges through it Vapor control è where is moisture sensitive material?
which direction is the vapor drive? do we need to allow diffusion or control it?
