NC-2009 IEQp1:Minimum IAQ Performance

Local Code more stringent than Ashrae 62.1

Our project has to achieve CA Title 24 which is more stringent than Ashrae 62.1. 1) In the form we are asked to show a comparison of both codes, that would be a comparison of section 6 (calculus procedure) of ashrae towards title 24? or the whole section 4 to 7? Is there somewhere on the web where this comparisson is already made? 2) I understand we have to upload the ventilation rate calculations for both codes. Can we do this in .xls spreadsheets of our own for both codes? Or we have to use VRP/62MZcalc for Ashrae? Thanks in advance for your response.

1) here is an Apendix Appendix H: Comparing ASHRAE/IESNA 90.1-1999 and Seattle Energy Code that could help you as an example: http://www.ci.seattle.wa.us/dpd/stellent/groups/pan/@pan/@sustainableblding/documents/web_informational/dpds_007598.pdf 2)You can do it in .xls spreadsheets as long as you follow the corresponding formulas.
