ASHRAE 90.1-2016 has adopted Standard 169-2013; counties that moved to a different climate zone could have different requirements than before.

</div>
</div>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have a question about the correct Climate Zone for 90.1-2010. This is for Toronto, Ontario. Table B1-2 lists Toronto in Climate Zone 6. Table D-2 shows HDD = 7306 for Toronto.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">But the ASHRAE Fundamentals 2017 and the Ontario Building Code show HDD = 7006 for Toronto. That would put Toronto in Climate Zone 5.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Therefore, I am wondering if I should use Climate Zone 5 for determining the baseline model envelope characteristics for a LEED v4 submission? Or would that bring the wrath of the reviewer?<o:p></o:p></p>
