Annette , I agree with you regarding providing cost savings on energy related systems , which should be easy to figure , if you have the home rated for Energy Star by a HERS rater . For example , the 1st home I built Energy Star had a HERS Rating of 48 (52% more efficient than a code built home ) and LP Gas & Electric costs are estimated to be $157.17 per month with a savings of $170.27 per month . The cost for all the Green/ Energy Star options was approx. $15,000.00 or $89.94 per month at 6% interest for 30 years . The net savings is $170.27 - $89.94 = $80.33 per month net , if financed . Many Green items don't have easily quantifiable monetary paybacks like Low V.O.C. paints & adhesives , Green Label Carpet , Rain Barrels , etc.. , so that is why some builders stutter when asked .
Carson , I agree with getting Green Data on the MLS ! My problem is I have only Certified Green Home for sale in the entire county --someone has to be the pioneer ! Also , I'm a custom homebuilder , so most Green / Energy Star Homes I build are for Clients & never go on MLS . Keepin' it Green !
