I'm an electrical designer and I'm trying to see if the lighting for a job we are working on passes the energy code. I'm getting error messages when I try to calculate. Most of the errors seem to be that I didn't enter a 'system'. Is there a way to calculate just the lighting without having to enter mechanical info?
Also, does anyone know what energy code to use for Orlando. I think it's Ashrae 90.1 2007 but not sure.
Unfortunately you will not be able to run a report on an incomplete building to check just the lighting compliance because there is a trade off between building elements that includes lighting. You can however go into your tools and settings menu and set your feedback setting to get detailed compliance feed back on different pages of the program. With this set you can view initial compliance numbers on individual spaces for lighting but as I mentioned there is a trade off so this may not necessarily reflect exact final results when everything else is taken into account.
*Sorry about the cut off note, it reads, "Note: Lighting Power Compliance is based on entire building."
As for the current code, one can't say that it ASHRAE 90.1-2007. In general though one could say it is 20% tighter, or better) than ASHRAE 90.1-2004 with some updates.
I hope this helps.
