Construction

The contractor schedules any necessary air pressure or blower door tests in their proper sequence. Testing occurs at various construction phases and ideally with a test unit to identify any leakages and opportunities for improvement in other units.

Orient all subcontractors to air-sealing goals and quality-control practices.

A nonsmoking policy during construction is not required for this prerequisite, but it is a good idea for the contractor to adopt and enforce such a policy, particularly after the

Compacted soil from high vehicle traffic prior to or during construction can severely limit natural infiltration of stormwater.

Commissioning water reuse systems will help ensure they operate as designed. This step can be incorporated EAp1: Fundamental Commissioning, or EAc3: Enhanced Commissioning.

Enhanced commissioning extends into the system startup phase, bridging the gap between design into the operations hand-over. Design and installation is only the first part of running an energy-efficient building. The real benefits are realized during operation.

The CxA documents system startup procedures and operations as part of the training manual.

The CxA develops a

LEED documentation can be submitted prior to the final commissioning report being completed, including verification of commissioned systems. A contract to complete these items is sufficient.

Functional testing, in which the whole system, and depending on scope, individual components are tested, is a critical part of commissioning.
