As part of a residential project aimed at LEEDv4 BD+C certification, we are studying the different possibilities to meet the "Enhanced Indoor Air Quality Strategies" credit with the strategy 7. Operable Windows which requires to have opening windows for 75% of the spaces regularly occupied. However, by consulting section of ASHRAE 62.1-2016 with addendum l, we understand that it is required to have windows in two opposite places of the same space, so in a case of residential project, to have crossing apartment. Do we understand the requirement of this strategy or would there be an error in the LEED credit and it would be section 6.4.1.

Have any of you used this strategy for a residential project with non-crossing apartment or is it the only way to be able to meet the requirements of this point?

Thanks in advance!
