Weatherization Program Brought Back to Stability for FY 2013 and 2014

I recently received the email below from a fellow supporter of the Weatherization Program regarding the current status of Federal funding for the Low Income Weatherization program.  

Relatively speaking, while I have done little in terms of personal lobbying in DC at the Federal level on Weatherization, Brad Penney deserves credit as one of the greatest leaders in personally convincing members of Congress to fund the Weatherization program during the FY2013 and 2014 - the two years…

Window Improvement vs. Window Replacement

Most energy audit reports place windows very low on their list of energy improvement priorities. This isn't surprising because of the relatively high cost of replacement windows coupled with what are commonly marginal improvements in their thermal performance.

Code Conflict Between 2012 IRC and 2012 IECC

It has come to my attention that there may be a building science-based conflict in the language of the 2012 International Residential Code (IRC) and 2012 International Energy Conservation Code (IECC).

The 2012 IECC sets the mandatory blower door tested and certified air infiltration rate at 5 ACH50 in CZ1 & 2 and an even tighter 3 ACH50 in CZ 3 and above. The problem lies in the fact that the new…

Home Performance and HVAC Contractors: Recent Legislative Initiative In Texas

As energy auditors and raters went about their business of testing homes, performing energy audits and HVAC system inspections, they discovered and reported certain “problems” to the homeowners of Texas.
