While it is correctly pointed out that previous CIRs have addressed this issue for LEED-NC v2.1, it should be noted that due to the changes to how sky glow concerns are now addressed by this credit, the old CIR is not applicable to LEED 2009 projects. Therefore, uplighting a flag is permissible provided that the credit requirements (including that the total percentage of light emitted above 90 degrees from nadir is within the allowable threshold relative to the declared environmental zone) are met.It should further be noted that there are many manufacturers of flagpole downlighting. It is recommended that the project team work with an exterior lighting designer to identify additional options.Applicable internationally.
