85 Energy Savings Plus Health | INDOOR AIR QUALITY GUIDELINES FOR MULTIFAMILY BUILDING UPGRADES 1.0 Moisture Control and Mold (continued) Assessment Protocol and Action Verification Complete N/A NOTES MA 1.8 Used nonporous construction materials in moisture-prone areas. MA 1.9 Protected open roof areas from rain during construction, and designed and constructed roofing systems and flashing details to ensure proper moisture barriers. Repaired leaks before air sealing or insulating the attic. MA 1.10 Protected on-site materials from moisture. EA 1.1 Retrofitted crawlspaces so that they are sealed, insulated, ventilated with conditioned air, properly drained and waterproofed. Installed a high capacity, energy-efficient dehumidifier in the space (if climate conditions warranted). EA 1.2 Followed EPA or other professional guidance to perform additional activities to remediate mold growth. 2.0 Asbestos Assessment Protocol and Action Verification Complete N/A NOTES AP 2.1 Determined potential asbestos hazards in the building and identified asbestos-containing materials (ACM). Completed assessments for ACM prior to initiating building upgrade tasks that have the potential to disturb ACM. AP 2.2 If unsure whether material contains asbestos, contacted a trained and accredited asbestos professional to assess, sample, and test the material, as needed. Notified the building owner and/or property manager of any ACM identified during the assessments. MA 2.1 Addressed ACM during building upgrades and used accredited personnel for abatement or repair. Immediately isolated the area if suspected ACM was found to be damaged (e.g., unraveling, frayed, breaking apart). For suspected ACM that must be disturbed as part of the project, contacted an accredited and properly trained asbestos professional. MA 2.2 Exercised caution to prevent the release of asbestos particles into the air during work activities (e.g., no dusting, sweeping or vacuuming ACM debris; no sawing, sanding, scraping or drilling holes into ACM; no using abrasive pads or brushes to strip ACM). MA 2.3 Did not remove or disturb insulation that appears to be vermiculite. MA 2.4 Conducted asbestos abatement before blower door testing and exercised caution when conducting blower door testing where friable asbestos or vermiculite attic insulation is present (e.g., used positively pressurized blower door testing).
