<p class=MsoNormal style='margin-bottom:12.0pt'>Hi Everyone,<br>
<br>
Was wondering if someone could clarify if a hotel falls under
&quot;residential&quot; within the ASHRAE 90.1 guidelines.&nbsp; I'm modeling a
hotel that is G+6, and is filled with guest rooms except for the ground floor
which includes a lobby and small cafeteria.&nbsp; I find that this
clarification becomes especially important when doing the base case model using
the guidelines from appendix G as it makes a large difference in the type of
system to use.&nbsp; In the user manual, on page G-22 to be specific, The last
paragraph states that &quot;Residential spaces in buildings are used primarily
for living and sleeping.&nbsp; They include, but are not limited to, dwelling
units, hotel/motel guest rooms, dormitories... etc.&quot; And for this reason I
have assumed the building to be residential, but because it says
&quot;residential SPACES&quot; instead of &quot;buildings&quot; I am starting
to question it.<br>
<br>
Also, has anyone had any experience modeling solar hot water heaters in
VisualDOE and if so, how have you gone about modeling it?<br>
<br>
Thanks for the help!<br>
<br>
