Occupied Buildings under Construction."

a. If Owner authorizes use of permanent heating, cooling, and ventilating systems during construction period as specified in Attachment G.K -

Ellington AFB (EF) Construction Facilities And Temporary Controls, install filter media having a MERV 8 according to ASHRAE 52.2 at each return-air inlet for the air-handling system used during construction.

b. Replace all air filters immediately prior to occupancy.

B. Credit IEQ 3.2: Pending approval from the Project Manager, comply with one of the following requirements:

14000 cu. ft. of outdoor air per sq. ft. of floor area while maintaining an internal temperature of at least 60ºF and a relative humidity no higher than

60%.

b. If occupancy is desired prior to flush-out completion, the space may be occupied following delivery of a minimum of 3500 cu. ft. of outdoor air per sq. ft. of floor area to the space. Once a space is occupied, it shall be ventilated at a minimum rate of 0.30 cfm per sq. ft. of outside air or the design minimum outside air rate determined in IEQ Prerequisite 1, whichever is greater. During each day of the flush-out period, ventilation shall begin a minimum of three hours prior to occupancy and continue during occupancy. These conditions shall be maintained until a total of

14000 cu. ft./sq. ft. of outside air has been delivered to the space.

i. Conduct baseline indoor-air-quality testing, after construction ends and prior to occupancy, using testing protocols consistent with the

EPA's "Compendium of Methods for the Determination of Air

Pollutants in Indoor Air," and as additionally detailed in the

USGBC's "LEED-NC: Reference Guide."

d. For each sampling point where the maximum concentration limits are exceeded, conduct additional flush-out with outside air and retest the specific parameter(s) exceeded to indicate the requirements are achieved.

Repeat procedure until all requirements have been met. When retesting noncomplying building areas, take samples from same locations as in the first test.

e. Air-sample testing shall be conducted as follows:

i. All measurements shall be conducted prior to occupancy but during normal occupied hours, and with building ventilation system starting at the normal daily start time and operated at the minimum outside air flow rate for the occupied mode throughout the duration of the air testing.
