thanks for your reply. i actually did the exact same search in google and went through them all. What i am looking to do is set up an excel database for my company that can track energy usage, gas, elec etc in different area. show usage in different areas and the put plans together to save. the more i think about it the more complex i see it becoming, how different areas work. I thought somebody out there may have had some experience in this that could point me in the right direction, starting at high level and then working it's way down to the ground..
hope this clarifies things
