[BLDG-SIM] Software for Modelling Ventilation and Thermal Mass

[Jeff Haberl]

FYI

 

Although the ground heat transfer in EnergyPlus is more accurate, we've
found that DOE-2.1e does a reasonable job if you use Winklemann's method
for effective U-values, this has also been updated again in the new
Huang et al. method. 

 

This works best when driven by the synthetic ground temps from TMY2.
Results from a comparison against measured ground temperatures for a
Habitat House in Texas show good agreement with both methods.

Subject: [BLDG-SIM] Software for Modelling Ventilation and Thermal Mass

 

I'm currently working on a project in Berkeley, CA with an underground
concrete building with very high thermal mass.  We would like to avoid
air conditioning by mechanically ventilating the building at night, and
would like to model this for some preliminary results.  

Does anyone have any suggestions for an appropriate software program to
model this?  Are the ground heat transfer/thermal mass modeling
capabilities of DOE 2.2 are sufficient to model this project in eQuest
or Visual DOE?

Right now, we are planning on using EnergyPlus, but I wanted to make
sure there wasn't another (less time consuming option) out there!  Does
anyone know if any of the EnergyPlus interfaces could handle this (i.e.
Design Builder)?

Thank you!

Kendra
