though you’re not allowed to), is that in some instances permanent fenestration
shades can be detrimental to your annual energy performance. Such shades almost
always simultaneously help and hurt your HVAC systems – as they block
solar load contributions in the summer (when you don’t want them), but
also in the winter (when you do). Glare issues aside, identical permanent shades/fins
can easily be thermally helpful on one orientation but not another for the same
project.<o:p></o:p></span></p>

<br>
The baseline has to be modeled as per G3.1.5 which does not require shading
devices to be modeled. Why would you want to model them in the baseline ?? This
will only compromise your energy savings.<o:p></o:p></p>
