CSST Piping and Lighting Strikes

Here is some interesting info on CSST gas pipe. If you are specifying CSST in any of your projects you should be aware of this information. We have see this first hand on one project here in south florida. A bulding official just sent me photos of another instance. For the time being we are switching back to steel pipe. Here are a couple of websites to review. The Trakpipe looks encouraging. Please let us know if anyone else has experienced this condition.

Crist's Renewable Energy Plan

Charlie Crist on Friday won an important victory in his plans to slash Florida's greenhouse gas emissions and boost renewable energy. The Florida Public Service Commission unanimously agreed to require the state's utilities to generate 20% of their power from renewable resources by 2020, resisting industry efforts to weaken Crist's goal. The vote sets the agenda for state legislators, who will have the final say later this year. [Source: St. Petersburg Times]

Sulfur in Drywall Causing Copper Corrosion in Homes

I have recently heard within our industry that the drywall coming out of China has high levels of sulfur in it which is causing all kinds of problems. One of the biggest areas has to do with the effects it is having on copper piping. My good friend and fellow colleague, Ron Bailey of Bailey Engineering (who specializes in sick buildings) sent me this:

"Some Florida homes have experienced blackening of copper pipes; often accompanied by pinhole corrosion. In some instances, odors are present as well.
Generally these symptoms are first noticed by a failure of the home's air conditioning evaporator (indoor) coil due to the blackening of the coil and pinholes resulting in the release of the refrigerant gas. The cause has been traced to Chinese manufactured drywall (gypsum) imported after the demand increased following the hurricanes of 2005. An Informational Release from the United States EPA Region 4 office, reported that drywall samples were placed in chambers with copper samples. It stated "copper turned black ;only in the chambers of imported gypsum. Microscopy testing conducted after 18 weeks showed pitting corrosion." The release also stated " the drywall is releasing these sulfur compounds after more than a year.""

LEED AP

I am very please to say that I have passed the LEED NC 2.2 test! I found the exercise to be quite challenging. And I have a few tips for anyone who might be thinking of doing this. A very good resource can be found at www.intheleed.com. A study guide can be purchased at this web site for around $50. The guide was prepared by Patrick Flynn LEED AP and provides an excellent method for studying for the test. Prior to finding the Flynn materials , I completed a eight hour seminar ($600) but it was not that helpful. Plus I found information in the seminar material that was not current. The Flynn memorization charts rock the house!!!
