New Mexico Housing Stats
Population 2 Million
Housing units 905,000
Detached and attached homes 615,000
Homes built before 1990 490,000 or
about 80%
Data from US Census 2010

What is important about 1990
Beginning of Energy Codes: Late 1970’s, but really took off with the 1998 IECC version. Now increased efficiency codes available every 3 years. NM currently using 2009 IECC.
Homes built before 1990 are easiest to make significant improvements regarding energy and water use.
Average age of homes is 45 years or built in 1969.
This does not mean that if your home is built after 1990 it should not have its efficiency evaluated.

Energy Use in the 21st century

Compare to new homes

The Energy Audit for Homes
HERS RaterBPI Auditor
These can do an audit concerning Building Envelope Water Use Combustion Safety Maintenance issues
Compare energy consumption with others

The HERS Index works well for New Homes
Can view all the construction at framing and final stages.
Do an evaluation of the Construction Documents before work starts, and make adjustments.
For existing homes it’s more costly and less accurate to get a HERS rating on the home, but there are great options for assessment of a home.

What about water use?
![Page 14: Green Retrofits for Existing Homes](https://reader035.vdocument.in/reader035/viewer/2022062519/5681514f550346895dbf721a/html5/thumbnails/14.jpg)
Water Efficiency Rating System (WERS)
Calculates indoor water use savings
For new homes; compares with industry standards
For existing homes; compares existing with replacement

Other benefits of Home Audit
Combustion SafetyLead Paint issues (prior to 1978; NM findings at about 11%)Mold IssuesStructural IssuesRadon
Most Remodelers do not have training in all these areas.
Audit Cost is modest compared to total project cost ($250 to $500)
Rigorous Training & Equipment, compared to the average “Home Inspector”

Last Year Next Year
30 day sessionAlmost passed an
incentive for energy and water efficiency upgrades to existing homes.
Burned through 2014, 2015 and 2016 SBTC
60 day sessionLegislative interest to
continue SBTC (in some form)
Add Water Efficiency Incentives
Add Existing Homes Improvement Incentives
Talk to your legislator
