Oldcastle Precast Modular Group LEED® build green. everyone profits & Precast Concrete Building Systems Achieves Points in ----- Indoor Environmental Quality Category   *Credits 3.1, & 5 : The insulated precast concrete building components contribute to these credits because the system produces no dust or airborne contaminants during construction and also does not allow moisture to be absorbed into the insulation of the walls-(credit 3.1).The wall systems limit or eliminate the transmission of moisture through the envelope, which eliminates condensation on the wall surfaces. They also contain no consumable material within the wall which contributes to the development of mold-an airborne contaminant.-(credit 5)     *Credit 7.1: The use of high mass wall systems provide a more comfortable environment. This is achieved by eliminating cold or hot spots in the occupant zones and by maintaining wall temps at or near the interior operating conditions.     *Credit 4.1: Sealants used in the manufacture of precast modules meet VOC limits of this section   *Credit 4.2: Paint materials used in the manufacture of the precast modules meet the VOC limits of this section * Indicates points where precast concrete components helped obtain certification Oldcastle Precast Modular Group 514 Township Line Road--Telford, PA 18969 Phone: 215.257.2255 Sustainable Site Energy & Atmosphere Materials & Resources Indoor Environment Quality Innovation & Design
