Energy Savings Plus Health | INDOOR AIR QUALITY GUIDELINES FOR MULTIFAMILY BUILDING UPGRADES 9 Examples of Multifamily Residential Building Upgrade Projects Examples of IAQ/Health Risks and Opportunities Potentially Applicable Priority Issues Concrete Floor Sealing • Repairing and sealing floor penetrations • Sealing cracks and joints in floors • Applying floor sealer/ paint IAQ/Health Risks: • Asbestos-containing material, lead paint, PCBs or mold may be disturbed. • Sealing the building envelope may increase levels of indoor contaminants, including radon, combustion by-products, moisture and mold, and VOCs. Adequate ventilation must be provided to dilute and remove indoor pollutants. Opportunities: • Understand and appropriately manage moisture emission rates and select sealants/adhesives with low-VOC or no-VOC content/emissions. • Reduce infiltration and conditions conducive to pest entry. • Seal cracks and joints in floors, which may be an integral part of a radon mitigation system. 1.0 Moisture Control and Mold 2.0 Asbestos 3.0 Lead 4.0 PCBs 5.0 Radon 6.0 Belowground Contaminants 7.0 Garage Air Pollutants 8.0 Pests 10.0 Building Products/Materials Emissions 11.0 Vented Combustion Appliances 18.0 Mechanical Ventilation for Individual Dwelling Units 19.0 Mechanical Ventilation for Multiple Dwelling Units Using Central Exhaust 20.0 Natural (Not Fan-Powered) Ventilation 22.0 Building Safety for Occupants 23.0 Protecting IAQ During Construction 24.0 Jobsite Safety Moisture Barrier for Ground- Level Slabs, Basement and Crawlspace Floors • Adding new moisture barriers • Modifying or repairing existing moisture barriers IAQ/Health Risks: • Asbestos-containing material, lead paint, PCBs or mold may be disturbed. • Uncovered dirt floor may contribute to excessive moisture migration into the building. • Installing carpet or floor tile over concrete floor that has a persistent condensation or water pooling problem will likely lead to mold growth. • An existing moisture barrier also may be an integral part of a radon mitigation system or other belowground contaminant mitigation measures and should not be disturbed. • Uncovered dirt floors may introduce pest populations and will promote rodent habitats. Opportunities: • Provide sealed moisture barrier over dirt foundation floors. • Provide moisture barrier beneath concrete slabs. • Select sealants/adhesives with low-VOC or no- VOC content/emissions. • Select exposed poly films with proper flame and smoke ratings. • Incorporate other radon mitigation and belowground contaminant mitigation measures as needed. 1.0 Moisture Control and Mold 2.0 Asbestos 3.0 Lead 4.0 PCBs 5.0 Radon 6.0 Belowground Contaminants 8.0 Pests 10.0 Building Products/Materials Emissions 11.0 Vented Combustion Appliances 22.0 Building Safety for Occupants 23.0 Protecting IAQ During Construction 24.0 Jobsite Safety
