Re: [EnergyPlus_Support] what can i do for convergence the result ?

[Mohammad Kheradmand <mohammadkheradmand@xxxxxxxxx>]

overestimate, for hottest day is almost 4-5 degree and for coldest day is 10-12 degree.

i will try to put infiltration and then i will see ..

Does the simulation underestimate or overestimate your experimental results?

You might need to consider the infiltration in your model. try to use simple convective heat transfer coefficient algorithm.

Use real weather data measured at site.  

what is the uncertainty in your measurements equipment. ? your results need to be within 1 deg difference. (3-4) degree difference is large.

I simulate my model for coldest and hottest a day of August, for comparing results between experimental and simulation results, i got reasonable result for hottest day(almost 4-5 degree differences ), but for coldest day i have difference almost 10-12 degree ...what is my problem?
