11 PRIORITY ISSUES ASSESSMENT PROTOCOLS Minimum Actions Expanded Actions Relevant Guidance/Standards DOE: Workforce Guidelines for Home Energy Upgrades (under development). Notes Replacing an atmospherically vented or fan- powered combustion device that draws combustion air from inside the home with a high-efficiency sealed combustion device can reduce the ventilation rate, which could result in cold-weather condensation in some building enclosures. If an atmospherically vented combustion device is causing an indoor humidity problem, it should be repaired in accordance with the Combustion Safety section (page 18). Relevant Guidance/Standards Combustion Safety (page 18). DOE: Workforce Guidelines for Home Energy Upgrades (under development). EPA Indoor airPLUS Specifications 1.5 and 1.6. Determine if there is any air-cleaning equipment designed to intentionally produce ozone (i.e., ozone generators) in the house. Relevant Guidance/Standards CARB: Ozone. Do not install air-cleaning equipment designed to intentionally produce ozone (i.e., ozone generators). Recommend removal of air-cleaning equipment designed to intentionally produce ozone, if present. Relevant Guidance/Standards EPA Indoor airPLUS Specification 4.7. EPA IAQ: Ozone Generators that are Sold as Air Cleaners. This cell is intentionally blank. Identify evidence of mice, squirrels or other rodents; termites; birds; bats; cockroaches or other pests. Note the location and identify pest-contaminated materials (e.g., nests, feces). Determine whether rodenticides or pesticides are being used. Remove pest-infested materials OR determine if professional assistance is needed to do so before conducting energy retrofit work in pest-infested areas. Alert owner of any termite infestations and inform owner of the need to seek assistance from an integrated pest management (IPM) professional (e.g., Greenpro, Greenshield or equivalently trained IPM professional). In areas with evidence of rodent infestations, patch with pest-resistant materials (e.g., copper mesh, hardware cloth, sheet metal, concrete) exterior holes that are larger than ¼ inch by ⅜ inch before applying air sealing materials (e.g., caulk or foam) OR before insulating. Protect air intakes from potential bird and pest entry (e.g., cover openings with ½-inch screen or galvanized mesh). Protect exhaust vents from rodent, bird and pest entry (e.g., cover openings with louvers). Avoid creating conditions that can clog exhaust, particularly dryer vents.
