What values were you comparing?
How do you match your experimental values to the simulated values?
Did you have modified current data weather file?
How do you mount your thermometers for temperature measurement?
Use real weather data measured at site is easy to say and difficult to obtain and insert into the EPW file.

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?
regards
