<p class="MsoNormal" style="margin-bottom:0in;margin-bottom:.0001pt;line-height:normal"><span style="font-size:12.0pt;font-family:"Times New Roman","serif"">Dear colleagues,<br>
<br>
I'm looking into furniture/internal mass modeling in energy models particularly
within the environment of EnergyPlus but also not limited to that. <br>
<br>
I have two questions I guess:<br>
<br>
1, Are there any modeling guide or reference building report that may give
recommendations/instructions on how to represent furniture/internal mass inside
a building if there is no much detailed information? I guess all I'm asking is
are there any published data-set, or default values in terms of material
property and area to represent furniture like what could be easily found about
schedules and occupancy density?<br>
<br>
COMNET modeling guide has only one paragraph about it and it mentioned
"The interior thermal mass and modeling assumptions in the baseline
building shall be the same as the proposed design."<br>
Currently what I have is from Building America House Simulation Protocols:
"The internal mass of furniture and contents shall be equal to 8 lb/ft2 of
conditioned floor space. For solar distribution purposes, lightweight furniture
covering 40% of the floor area shall be assumed."<br>
<br>
2, DOE reference commercial buildings have internal mass objects in the idf.
file, where does the information come from?<br>
<br>
Appreciate your input!<br>
<br>
Best,<br>
<br>
