<P></P>
<P></P>> Hi Dr. Varkie! <BR>> <BR>> <BR>> <BR>> Your question hinges directly on which energy code/standard is being <BR>> enforced. <BR>> <BR>> <BR>> <BR>> While someone on these lists might know definitively... this is a <BR>> question that is probably best answered by the local planning <BR>> departmentthat issues permits. I would advise calling, ask what <BR>> energystandard/code (if any) is adopted and whether review of that <BR>> code/standard is part of the permit review process (energy codes <BR>> in some <BR>> areas are adopted, but not enforced). You may be able to speak <BR>> directlyto the person who performs these reviews and if so she/he <BR>> may be able to <BR>> give you a direct answer to your specific question of scope. <BR>> <BR>> <BR>> <BR>> ~Nick <BR>> <BR>> <BR>> <BR>> <BR>> <BR>> <BR>> <BR>> NICK CATON, E.I.T. <BR>> <BR>
