6 <br />of MERV 13 air filters in all mechanically supplied outdoor air ventilation systems. This <br />applies to both the residential and commercial portions of this development. <br /> <br /> <br />Indoor Air Quality Impact Mitigation Measures <br /> <br />The following are recommended mitigation measures to minimize the impacts upon indoor <br />quality: <br /> <br />- indoor formaldehyde concentrations <br />- outdoor air ventilation <br />- PM2.5 outdoor air concentrations <br /> <br />Indoor Formaldehyde Concentrations Mitigation. Use only composite wood materials (e.g. <br />hardwood plywood, medium density fiberboard, particleboard) for all interior finish <br />systems that are made with CARB approved no-added formaldehyde (NAF) resins or ultra- <br />low emitting formaldehyde (ULEF) resins (CARB, 2009). <br /> <br />Outdoor Air Ventilation Mitigation. Provide each habitable room with a continuous <br />mechanical supply of outdoor air that meets or exceeds the California 2016 Building Energy <br />Efficiency Standards (California Energy Commission, 2015) requirements of the greater of <br />15 cfm/occupant or 0.15 cfm/ft2 of floor area. Following installation of the system conduct <br />testing and balancing to insure that required amount of outdoor air is entering each habitable <br />room and provide a written report documenting the outdoor air flow rates. Do not use <br />exhaust only mechanical outdoor air systems, use only balanced outdoor air supply and <br />exhaust systems or outdoor air supply only systems. Provide a manual for the occupants <br />(residential and commercial), that describes the purpose of the mechanical outdoor air <br />system and the operation and maintenance requirements of the system. <br /> <br />PM2.5 Outdoor Air Concentration Mitigation. Install air filtration with a minimum efficiency <br />of MERV 13 to filter the outdoor air entering the mechanical outdoor air supply system. <br />Install the air filters in the system such that they are accessible for replacement by the
