First off, I am not an Energy Auditor and don't hold those certifications or experience. I am a realtor with 2 green designations that assist my clients, both buyers and sellers, with energy efficient upgrades. It is my job to be able to convey my unique knowlege to help them lower their energy bills, improve indoor air quality, assist with allergens and if they care lower their carbon footprint.
You might have seen a post that was featured about Energizing my 1979 home. I'm still completing that process and hope to gain my NGBS certification for the home soon, when the Arizona desert climate allows a new Xeriscape project to be completed.
That said, I am working on an odor issue that has cropped up.
After installing Icynene in my attic, not removing the existing cellulose, I noticed an odor that kicks into high gear in mid-afternoon when the 16 SEER HVAC works diligently to cool this block constructed house.
The energy auditing company advised I could either remove the cellulose or aeroseal the ducts. I chose the latter solution but now wish I had removed the cellulose as the odor still exists, although much milder in nature.
Explaining this to a friend, he advised that if I remove the cellulose won't I be acting counter-productively in allowing the heat to enter the house? My thought is that I sealed the ducts and don't have that much heat gain in my attic.
The friend also asked why I would choose to remove the cellulose and not replace it? He also asked if I wouldn't be creating a pressure issue.
I'd love some answers from a different source that my energy auditor to verify my unspoken thoughts and to get good feedback for discussion so that I can better relay the dynamics of the products I constantly discuss.
