First of all, if you're simulating PV, we're going to recommend that you use the Type551 shading device in the TESS Electrical (formerly Green Building) Library from the TESS Libraries 17.01. The existing Type551 could be modified to do a single axis (east-west axis) tracking without a whole lot of work; however, doing a 2-axis tracking would indeed be a lot of work. Since you are a TESS TRNSYS customer, you may email TESS Technical Support (<a href="mailto:techsupport@tess-inc.com" target="_blank">techsupport@tess-inc.com</a>) if you need a software update.<br>

Leo,<br>
there is no direct output for energy density. I would recommend
integrating the building energy use during your simulation then
multiplying it by the building area afterwards in your Excel sheet.<br>

Subject: Re: [TRNSYS-users] TRNSYS models for longwave radiation exchange withina zone<br>Dear Matt Duffy,<br>
<br>
Thanks for recommending these resources. I have read them, but I am<br>
still not clear what is the difference between the standard (starnet)<br>
model and the simple (combined) method. In the TRNSYS 17 manual<br>
section Section 5.4.1.6, there is no explanation for the simple<br>
(combined) method (pg. 5-153). Could you please explain what is meant<br>
by simple (combined) method? What is its difference from the standard<br>
(starnet) model?<br>
<br>
Thanks in advance,<br>
