If you don’t like the energy codes, just get your buddy on the city council to help change them. Is this business as usual in Sin City?

Las Vegas has a long history of passing off the unconventional—and even nefarious—as perfectly ordinary. From that perspective, this story is just another chapter in the colorful narrative of the city: Councilman is involved with commercial development. Councilman’s business partner doesn’t like building regulations. Councilman proposes a change to the regulations to benefit his project. The proposal passes by the narrowest of margins and over the objections of actual building professionals.

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?

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.
