<div dir="ltr"><font color="#0000ff">Hi Ronny,</font><div><font color="#0000ff"><br></font></div><div><font color="#0000ff">I guess the first variable is as per without heating/cooling having some profile or schedule as per eQUEST.</font></div><div><font color="#0000ff">so the variable two is also having profile which can be ON for 24 hours which can be without heating or cooling</font></div><div><font color="#0000ff">and the third variable can also be having 24 hour profile or schedule.</font></div><div><font color="#0000ff"><br></font></div><div><font color="#0000ff">So there can be discrepancy in the first variable as the profile or schedule is OFF for other time. The first variable is as per the set-points for the hours when profile is ON.</font></div><div><font color="#0000ff"><br></font></div><div><font color="#0000ff">Variable two and three can have profile to be ON for all the hours.</font></div><div><font color="#0000ff">These comments are as per IES-VE as i already had these kind of experience sometime back.</font></div><div><font color="#0000ff"><br></font></div><div><font color="#0000ff">The Building Template Manager can have some profile for the occupied and unoccupied hours as i have never seen these kind of variables in eQUEST.</font></div><div><font color="#0000ff">Pardon me if this is as per eQUEST.</font></div><div><br></div><div><font color="#0000ff">So the second and the third variables are having the logic that the current hour temperature are as per the exact hours point value but the average temperature during this hour is the average of all seconds in the hour which is averaged out.</font></div><div><font color="#0000ff"><br></font></div><div><font color="#0000ff">So as per me the thing that you are looking for is the first variable whose profile or schedule should be having OFF for all the hours otherwise it is meeting the set-points as per profile. Then you will be able to do the analysis for unconditioned building for solar gains.</font></div><div><font color="#0000ff">Hence you need to switch off the profile or Schedule.</font></div><div><font color="#0000ff"><br></font></div><div><font color="#0000ff">Pardon me if you have not done it in IES-VE.</font></div><div><font color="#0000ff">I think this will be helpful.</font></div><div><br></div><div><br></div><div><font color="#0000ff">Thanks,</font></div><div><font color="#0000ff">Sharad Kumar.</font></div><div><font color="#0000ff">Green Horizon Consulting LLP</font></div><div><font color="#0000ff">Gurgaon</font></div><div><font color="#0000ff">India.</font></div><div><font color="#0000ff"><a href="https://www.linkedin.com/profile/view?id=151208255&trk=nav_responsive_tab_profile" target="_blank">Linked-in</a><br></font><div class="gmail_extra"><br><div class="gmail_quote">On Mon, Sep 7, 2015 at 1:32 AM, <span dir="ltr"><<a href="mailto:equest-users-request@lists.onebuilding.org" target="_blank">equest-users-request@lists.onebuilding.org</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Send Equest-users mailing list submissions to<br>

Variables 2 and 3 give very similar hourly data but are almost never identical. My understanding is that DOE2 considers the entire air mass inside a zone to be the same temperature for a given hour so I am not sure what is the difference between variables 2 & 3.</div><div dir="ltr"><br></div><div dir="ltr">I am hoping some of the more experience DOE2 users with knowledge of how the indoor space temp is calculated can explain the difference between these three variables and suggest which is the most approrptrie one to select for my exercise.</div><div dir="ltr"><br></div><div dir="ltr">thank you</div><div dir="ltr"><br></div><div dir="ltr">Ronny</div><div dir="ltr"><br></div><div dir="ltr"><br></div><div dir="ltr"><br></div><div dir="ltr"></div></div></div><div bgcolor="#FFFFFF" text="#000000"><blockquote type="cite"><div><div></div></div></blockquote></div></blockquote></div><br></div></div></div>
