<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Hello all,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’ve been asked by a client to complete a shading analysis that quantifies the impact of an exterior canopy on the comfort of occupants outside of the building in a courtyard area. In the past, I’ve done solar irradiance simulations to
show the effect of shading, but irradiance doesn’t directly translate to comfort in a straightforward way.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’d like to be able to quantify how the canopy will increase the amount of time that occupants will want to spend outside in the courtyard. For example - per this metric, the number of comfortable hours in the courtyard will increase by
X% over the year. <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I know the heat index is commonly used to assess comfort, but this only includes temperature and humidity, not a solar component.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Has anybody completed a study like this? If so, what metrics did you use to provide meaningful feedback on the effect of the exterior shading on occupant comfort (outside of the building)?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
