Energy Savings Plus Health | INDOOR AIR QUALITY GUIDELINES FOR MULTIFAMILY BUILDING UPGRADES 13 Examples of Multifamily Residential Building Upgrade Projects Examples of IAQ/Health Risks and Opportunities Potentially Applicable Priority Issues MATERIALS SELECTION AND REPLACEMENT Adhesives and Sealants • Application of materials used during energy upgrades for air sealing • Application of materials used for adhering and fastening components IAQ/Health Risks: • Asbestos-containing material, lead paint or PCBs may be disturbed when removing previously installed adhesives or sealants. • Weatherization and air sealing can reduce air exchange rates and result in elevated levels of contaminants indoors if there is inadequate ventilation. Opportunities: • Always select sealants and adhesives for indoor use with low-VOC or no-VOC content/emissions. • Select outdoor sealants for long life to keep out water and, when possible, with low-VOC or no-VOC content/emissions. • Ensure adequate outdoor air ventilation after weatherization and air sealing. 2.0 Asbestos 3.0 Lead 4.0 PCBs 10.0 Building Products/Materials Emissions 22.0 Building Safety for Occupants 23.0 Protecting IAQ During Construction 24.0 Jobsite Safety Carpet and Flooring • Replacing existing carpet • Installing new carpet over uncarpeted areas • Replacing or repairing existing floor tiles • Installing new flooring over existing floor surfaces IAQ/Health Risks: • Asbestos-containing material (many floor tiles in older buildings were made of asbestos), lead paint, mold or large quantities of dust may be disturbed. • Carpet and flooring may be contaminated with PCBs if PCBs have migrated via indoor air from caulk and/or lighting ballasts that contain PCBs. Opportunities: • Isolate the work area to reduce dust migration caused by carpet and flooring removal. • Select low-VOC materials, including carpets, resilient flooring, adhesives and sealants. 1.0 Moisture Control and Mold 2.0 Asbestos 3.0 Lead 4.0 PCBs 9.0 Tracked-In Pollutants 10.0 Building Products/Materials Emissions 22.0 Building Safety for Occupants 23.0 Protecting IAQ During Construction 24.0 Jobsite Safety Painting • Removing old deteriorated paint (scraping and sanding) • Repainting existing surfaces • Painting new surfaces IAQ/Health Risks: • Asbestos-containing material, lead paint or PCBs may be disturbed. • Indoor surfaces may be contaminated with PCBs if PCBs have migrated via indoor air from caulk and/or lighting ballasts that contain PCBs. Opportunities: • Select paint with low-VOC or no-VOC content/ emissions and do not conduct dry sanding without rigorous containment. 2.0 Asbestos 3.0 Lead 4.0 PCBs 10.0 Building Products/Materials Emissions 22.0 Building Safety for Occupants 23.0 Protecting IAQ During Construction 24.0 Jobsite Safety
