Federal preemption rules major roadblock for higher energy efficiency, organization says
June 29, 2017
I recently spoke with Ralph DiNola, CEO of Portland, Oregon-based New Buildings Institute, a nonprofit working to improve the energy performance of commercial buildings, who told me about a decades-old bump in the road: federal preemption rules.
The expected rise in steel prices does not necessarily mean the rise of total costs. In the HVAC industry, one way to offset increased steel prices is to reduce the cost of labor to make ducts and fittings by being more efficient. How do we do this? Machine automation.
I find it hard to believe that very many contractors would decide to check out the online equivalent of a rummage sale if they needed a few parts. But plenty of people with access to ductwork seem to think it’s a good idea.
As I write this, it’s the last day of the 2017 AHR Expo in Las Vegas. While SNIPS editor Michael McConnell is making his way to company booths we may have missed, I’m already back at home in Michigan with some time to reflect on my first visit to an HVAC/sheet metal trade show.
Sheet Metal gauge, or more formally, Manufacturer’s Standard Gage for Sheet Steel, is derived from the United States Standard Gage established by Congress in 1893. (Machinery’s Handbook, 29th Ed., Industrial Press 2012, p.2608)
Ductwork is one of those things that doesn’t get much attention as long as it works and doesn’t leak too much -- until something is suggested by a standards-writing organization that the HVAC construction industry doesn’t uniformly agree with.
