Yeah, Morgan is right. We don't have humidity, we have rain. I can get hot for up to a week in the summer and if you are in a commercial building your clients will be very unhappy if you don't have AC. A very good climate for heat pumps VRV/simultaneous heating and cooling/or whatever, depending on your usage and footprint.<br>

John - The Tacoma climate is very similar to Seattle. The winters are<br>
cool and wet, and the summers are cool and dry. The proximity of the<br>
Puget sound keeps the humidity in the comfort zone in general. The<br>
climate is definitely heating dominated, and cooling is unnecessary for<br>
most occupancies, as long as some moderate amount of attention is paid to<br>
the envelope design. A useful climate visualization tool is "climate<br>
consultant" a free software that you can download here:<br>

Subject: [Bldg-sim] Tacoma Washington General Climate<br>
<br>
To the group,<br>
<br>
I am starting an HVAC design project at Tacoma Washington (I live<br>
in<br>
Nebraska). I can look up the ASHRAE design conditions, but I am wondering<br>
if<br>
somebody can give me a clearer picture of the climate. (This goes with<br>
the<br>
change in thinking between designing for worst conditions and designing<br>
for<br>
year around energy savings.)<br>
I am looking for things to consider in my design.<br>
<br>
Examples: Here in Nebraska it gets really cold and hot and humid. Due to<br>
the jet stream the temperature can swing from the 20s to the 70s within a<br>
week so the design must be able to react.<br>
I also finished a design in Colorado which I know is arid and dry.<br>
Humidity usually a problem.<br>
<br>
I don't know exactly what I'm looking for, I am just not familiar<br>
at<br>
all about what to expect. I think the humidity issue is something I would<br>
like to know better. (this may determine if I go with DX or chilled<br>
water.)<br>
<br>
Thank you for any help,<br>
