Thank you very much for your kind help.<div> I tried the bin file converter, but it's given me a error message "Invalid file name". And the file downloaded from  "Trane" website, 
<a href="http://www.trane.com/Commercial/DesignAnalysis/weather.aspx">http://www.trane.com/Commercial/DesignAnalysis/weather.aspx</a>  seems working. But they also don't have weather files for Sri Lanka.<div>Moreover, is there anyway that we can input weather data and create a .bin file? because the weather data files that available are not for 2011 it seems.</div>
<div>Again thank you very much for helping me out.<br><br><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div text="#000000" bgcolor="#FFFFFF">
