LEED-BDC 2009 reference guide gives an example table for EQ Prerequisite 1 on
page 413 as far as documentation for natural ventilation. If you go after
EQ Credit 2 for the project you will need to either comply with CIBSE Manual 10
or do a CFD model to show that the natural ventilation rates exceed the
requirements of ASHRAE 62.1-2007 by 30%.<o:p></o:p></span></p>

EAc1, ASHRAE 90.1-2007 Appendix G requires that the baseline and design models
use the same OA supply flows; however, the old “public” CIRs
allowed teams to account for ventilation as an exceptional calculation
methodology. So as far as assuming natural ventilation – the
assumption you make is supposed to match the design as accurately as possible
(i.e. will tenants open windows or will they leave them closed due to an air
conditioning system) and the baseline is required to use the same OA strategy.
A third model can be created to account for energy benefits or costs of a
particular strategy if submitting this as an ECM.<o:p></o:p></span></p>

<p class=MsoNormal>the code states that natural ventilation works, but there is
a distance requirement from the window to the interior....I think 25 ft, that
must be maintained. If you have a depth greater than 25 ft, you have to
revert to mechanical means to promote air circulation in the areas greater than
25 ft from the window. there are operable window to floor area
percnetages (4%) to maintain as well.<o:p></o:p></p>
