we have a project of 20 floors of offices; and has 10 parking basements by local regulations.
The design of parking in basements requires extraction monoxide.

Currently is under construction and has just completed the construction of all basements in the rest of the year the following 20 stories, will be built and the project ended.

Those responsible for the construction request know if its possible to start the extraction system monoxide to help ventilate the basement; and whether this activity would be against the fulfillment of credit IEQc3 or more important if part of the support to be performed for the credit IEQc3.
