[BLDG-SIM] energy simulation of strawbale houses

[Mike Tillou]

Priya,
 
Download the DOE2.2(eQuest) documentation from DOE2.com.  There are six volumes (of .pdf) that explain how DOE2.2 works.  This will answer your questions on how to create the components within eQuest to use the data you develop.  As has already been mentioned DOE 2.2 is good at determining loads/energy but not specific conditions within a space. 
 
You may think about doing several models.  Use DOE 2.2 to simulate monthly/annual energy use (calibrate with utility bills) and a more advanced program to look at the thermal mass charachteristics of the strawbale wall and the effects on internal temp.
 
Be careful using HOBO temperature loggers, they are not well suited for measuring small temperature differentials because of their accuracy. 
 
regards,

Subject: [BLDG-SIM] energy simulation of strawbale houses


Hello,
 
I am graduate student at the Penn State university. My research is on the energy modeling of strawbale houses situated on the Northern Plains of US. Briefly explaining my objectives of research, i would be performing steady state and dynamic tests in labs to determine the R value of the strawbale specimen. This value would be used in energy modeling software to simulate the building performance of an already existing strawbale house. The results of this dynamic simulation would be compared with the temperature data that are being recorded using HOBO of the existing structure also used for simulation. For the purpose of simulation, I am considering eQuest but    DOE 3.0 also seems to be appropriate.
 
My concerns, for which I wish to seek suggestions, are how do I plug in the R value obtained from the lab experiments into eQuest. Is it possible to do so with any softwares efficiently. Also, I am not sure, how would I convert temperature data to be able to compare them with the results of the simulation model. 
 
Any time taken out to put down their thoughts of suggestions would be sincerely appreciated. It has been quite interesting to read the various questions, concerns and comments that come online through this list serve!
 
Thankyou very much.
 
Priya
