Action Steps

Projects with district energy systems must commission, for the prerequisite, all “downstream” equipment—systems installed for the building’s use and included in the project costs.

Review the Ventilation Rate Procedure methodology in ASHRAE 62.1-2007 Section 6.2 and the associated Table 6-1.

Develop the Basis of Design (BOD), working with the design team, including at least the architect, mechanical, electrical and plumbing engineers with lighting designer.

Evaluate and select ventilation strategies—natural, mechanical, or mixed-mode—during the pre-design phase

Owners' Project Requirements (OPR) are developed and signed off on by the owner with assistance from the

The contractor coordinates with subcontractors to ensure that construction practices adequately address the acoustics design.

Ensure that mechanical equipment is specified to meet the project’s acoustical goals.

Sound absorption coefficient requirements for the ceiling, wall and flooring materials should be included in project specifications.

Specify NRC of 0.70 for all ceiling tiles or a combination of ceiling and wall materials meets the 0.70 requirement for an area equal to the total ceiling area.

Run final acoustic calculations for the project and verify that goals are met.
