Greetings fellow North Carolinians,
Recently we have had the unique opportunity to serve on the Energy Code ad hoc committee that is helping to write the 2018 North Carolina Energy Code. What we have discovered is that this Energy Code Project has been very helpful in educating the committee on our current statewide rate of compliance.
You may recall back in 2012 when we made quite a leap in energy code efficiency. Many new air sealing and testing procedures were identified in that new code. We are now 4 years into the code cycle and we had the great opportunity to measure our success. The good news is - it is clear that the building community understands the intent of the code. The bad news is - they are not meeting that intent 100%. For example:
- Installing fewer than 75% high efficacy light bulbs. Only 46% of the homes we observed got this right. Could it get any easier?
- Ducts not sealed very well. Again, an easy fix if the installer is thoughtful in their work. In all cases sealant was used on the ducts, the sealant was just not installed properly.
- Thermal envelope sealing. Across the board the backing of kneewalls was poorly done. This paired with dropped soffit sealing are the two culprits in the air sealing category.
- Insulation Installation. The code calls for insulation to be substantially free of gaps, voids and compressions. Again, an easy fix if we follow the manufacturer's instructions.
In response this we have created a multitude of new resources which you will see in the information below. Visit our website to view and take those resources you need or want. Also, call us to schedule an onsite training, you cannot beat the price, FREE!
Getting this right is good for the builder, the homeowner and North Carolina.
Onward to 100%,
NCEEA Program Director
