Deep Energy Retrofit Measures

Pulling it all together: §  Plans (Plan!) §  Specification (Specify!) §  Verification (Verify!)


DER Measures Specification – Be Specific!

Control Functions Guide Specification §  Enclosure:

Ø Water control Ø Air flow control Ø Vapor Control Ø  Thermal Control

Ø  Mechanical:

Ø Space heating Ø Space cooling Ø Ventilation Ø Air mixing Ø Water heating

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?

§  BSC often asks for additional information in 1st round review Ø  To allow evaluation of whether the plan is sound

Ø Control functions è transition of control functions
