72 Energy Savings Plus Health | INDOOR AIR QUALITY GUIDELINES FOR MULTIFAMILY BUILDING UPGRADES VENTILATION Goal Confirm ventilation systems are functioning as intended to reduce buildup of moisture and contaminants in dwelling units and common areas. Moisture can contribute to mold growth and breathing problems such as asthma. Contaminants from kitchen cooking can contain small particles and nitrogen oxides that also can adversely affect health. Actions 1. Perform the following during annual inspections and at unit turnover: • Inspect bath and kitchen fans to determine whether they are clear of obstructions, operational and moving air at the correct airflow rates. Ensure that fans are operating as intended (e.g., manually or automatically controlled intermittent operation, continuous operation). • Remove any items put up by occupants to block airflows at supply or exhaust grilles. Identify the source(s) of occupant dissatisfaction that prompted blocking the airflows and take corrective action. • Replace filters in HVAC systems with new filters at unit turnover, semi-annually or as often as recommended by manufacturer. • Conduct a ventilation system assessment to determine whether adequate ventilation rates are being provided to dwelling units. • Assess ventilation rates in common areas. • Occupant Education: Advise occupants about the need to use exhaust fans in kitchens and bathrooms during activities that generate pollutants and moisture (e.g., cooking and showering). Educate occupants about the basic operation of ventilation, heating and cooling systems. This should include any maintenance (e.g., air filter change-out) and adjustments that are the occupants' responsibility.

Actions 1. Conduct regular inspections and preventive maintenance on all combustion appliances. Ensure proper venting of combustion by-products to the outdoors. Regularly inspect carbon monoxide alarms for proper operation. • Occupant Education: Ensure building occupants are provided with information on the hazards of combustion pollutants including carbon monoxide.
