Officials in North Carolina are taking proactive measures to ensure homes don’t keep getting destroyed by flooding, let alone repetitive flooding. The need to act is being driven by the fact that over 77% of homes damaged by Hurricane Matthew in 2016 were not located in federally designated flood zones.

Omaha Makes Big Code Update

Omaha, Neb., finally updates from the 2006 IRC.  

The city adopted an updated version of their codes, including the IRC. They had previously been on the 2006 IRC. Now, they are almost up to the 2018 IRC. One notable difference is that service water heating only needs to comply with the 2003 IECC. (No, that year is not a typo.) It should be noted that single-family dwellings, duplexes and townhomes with a window-to-wall ratio greater than 15% fall under the purview of the Nebraska state energy code.

Furthermore, NERA wants rates for such sales to be priced in accordance with the Public Utility Regulatory Policies Act of 1978 (“PURPA”) or the Federal Power Act. In essence, they are taking umbrage with full net metering.

Three More States Tweak Energy Codes

MINNESOTA
Energy Code Information: The state’s Construction Code Advisory Council approved a draft energy code based on the 2012 IECC. It then moved to a review by the state’s Department of Labor and Industry. A public comment period was held earlier this year, though the state first has to work through the issue of residential sprinklers. Once they finally get to the energy code discussion, they will review the following amendments proposed to both the commercial and residential codes:

Commercial: The IECC commissioning requirements were incorporated into ASHRAE 90.1-2010, so there is consistency between the code and standard.

Residential: Wall insulation R-value is R-21 for the prescriptive table, while the U-value table remains the same as it was. Ventilation requirements have been increased to balanced ventilation (cannot use exhaust or supply).Two options for basement wall insulation: R-15 continuous or R-10 exterior insulation; however, 2.5 ACH50 must be proven.Elements to ensure basement walls are waterproofed, which helps mitigate moisture damage.

Greener Living for All?

Posted by Mike Collignon

Mar 7, 2014 12:57:41 PM

There are a number of decisions that were made in 2013 that I feel point the residential homebuilding industry in a clear direction toward sustainability. Better still, some of these decisions will reinforce the importance of sustainability to homebuyers and homeowners. I’ll break this down into three categories:

Regulation
As I’ve reported elsewhere, building officials voted in favor of adding an ERI compliance path to the 2015 IECC. This is significant on a number of levels, some of which we didn’t delve into until now. Given the flexibility of an ERI, I believe we’ll see many builders choose this option, when states start adopting the 2015 IECC in two to four years. It requires strong performance levels, so the average builder will have to step up in order to comply. Meanwhile, the above-code builders will retain their market advantage by continuing to market their outstanding ERI scores. Also, they will face little to no disruption to their day-to-day business, and could face the very real possibility of expansion.
