ProPress is an industry proven, flameless press-type connection system for joining copper pipe. Its features are that is saves time and energy during installation, reducing the overall project\'s cost while increasing efficiency. It is also more of an environmentally friendly product when compared to conventional copper solder systems. After reviewing "EQ Credit 3.1: Construction IAQ Management Plan: During Construction" and interpreting its intent, it became clear that one opportunity for significant air quality improvement during construction would be the use of the ProPress system for all building piping systems (including domestic water, hydronic systems, hot water recirculation loop, grey water systems, etc.). If ProPress would be used entirely, no flames/solder, primers/glues would need to be introduced during the construction phase for the plumbing and mechanical system hydronic systems. Also, using this type of system on this project (although none are mentioned in the LEED NC), would have many significant advantages including: -Eliminates indoor air contaminants (Ammonium chloride, ammonia and hydrochloric acid fumes, etc) caused by soldering/brazing and associated releases from flux/smoke/soot, etc. - Possible respiratory problems associated with inhaling contaminants of soldering/brazing and primer/glue would be reduced for the installer. These benefits when compiled over the career of the plumbing contractor would have significant impact on the overall health of the individual and the exposed team during construction -Reduces the contamination and chemical treatment requirements at waste treatment facility -Eliminates personal injury associated with the use of soldering and brazing -The lack of flames on the construction site reduces the risk of potential fire damage especially important in a historical project -This project is located in Greensburg, KS. Many people are still without permanent locations to call home. The reduced time for installation will increase the overall efficiency for the plumbing contractor therefore allowing more time and energy to be placed rebuilding efforts. There is currently no clarification for an impact on IAQ in this manner so we are requesting a Credit Interpretation Request to rule if this system will contribute to earning the point for EQ Credit 3.1: Construction IAQ Management Plan: During Construction for the above mentioned efforts.
