Energy Savings Plus Health | INDOOR AIR QUALITY GUIDELINES FOR MULTIFAMILY BUILDING UPGRADES 94 17.0 HVAC Equipment Assessment Protocol and Action Verification Complete N/A NOTES AP 17.1 Conducted an HVAC assessment to evaluate the condition of existing HVAC systems and components in accordance with minimum inspection standards of ASHRAE/ACCA Standard 180 or other equivalent standards and guidelines. AP 17.2 Determined whether the existing HVAC systems are sized properly. If HVAC system replacements or modifications are anticipated, based heating/cooling load and equipment sizing calculations on post- upgrade conditions. MA 17.1 Repaired, modified or replaced equipment to ensure that existing HVAC systems operate properly. MA 17.2 Properly sized and installed any new HVAC equipment. MA 17.3 Ensured new HVAC systems for dwelling units have air filtration with a minimum MERV (minimum efficiency reporting value) 6 rating, and new HVAC systems for nonresidential spaces have air filtration with a minimum MERV 8 rating. For existing HVAC systems, checked with manufacturers to determine whether filters with these MERV ratings can be accommodated by the equipment and, if not, installed filters with the highest MERV ratings that can be accommodated. MA 17.4 Followed ASHRAE Standard 188-2015 or Occupational Safety and Health Administration (OSHA) Technical Manual, Section III: Chapter 7 Legionnaires' Disease to protect against bacterial growth in building water systems. MA 17.5 Trained building staff on operations and maintenance of the HVAC systems after the building upgrade. EA 17.1 Increased filter efficiencies in new and existing HVAC systems to the highest MERV ratings possible based on equipment capabilities. EA 17.2 Developed plans to conduct follow-up HVAC training with building operations and maintenance staff (e.g., 6 months or 1 year after the initial training). 18.0 Mechanical Ventilation for Individual Dwelling Units Assessment Protocol and Action Verification Complete N/A NOTES AP 18.1 Determined whether dwelling units have individual mechanical ventilation systems. For other outdoor air ventilation configurations, referred to Priority Issues 19.0 and 20.0. AP 18.2 Determined whether dwelling unit mechanical ventilation systems meet ASHRAE Standard 62.2-2013 requirements. AP 18.3 Determined whether ventilation provided to corridors and nonresidential spaces, as applicable, meets the requirements of ASHRAE Standard 62.1-2013.
