  2. What we will cover • Why maintenance is so important • ASHRAE’s new HVAC maintenance standard (S180) • What we are trying to maintain • Utilizing the standard • Achieving greater energy efficiency by managing pressure drop • The role of air cleaning • Where the standard is going

  3. The new‘Burbs’

  4. The earth is flatWe are competing for: • Jobs • Cash • Food • Resources • Energy

  5. Total Energy ConsumptionUnited States

  6. ASHRAE ‘Tips’ • Demand accurate design and construction records and understand how the system works • Demand accurate commissioning information; keep records up-to-date. • Change things that don’t work. • Check calibration of sensors against data and common sense. • Look for patterns in occupant complaints and apply cause analysis. • Decide whether to get to know the occupants or stay remote. Establish lines of communication.

  7. Tips (contd.) • Collect key data and use it to plot trends. • Establish energy baseline and sustain performance. • Use qualified well-trained staff. Operations and maintenance cost will exceed construction costs over the life of the building. • Read and apply ASHRAE/ACCA Standard 180, Standard Practice for Inspection and Maintenance of Commercial Building HVAC Systems. • Read and apply Chapter 38 of the ASHRAE Handbook, HVAC Application. • Take the test and obtain ASHRAE OPMP Certification.

  8. Especially Important • Collect key data and use it to plot trends. • Establish energy baseline and sustain performance.

  9. Our Concentration: Air Movement system

  10. Impact on Performance • Adequate – high efficiency • Lacking – compromised performance

  11. ASHRAE/ACCA/ANSI S-180 • Title • Standard Practice for Inspection and Maintenance of Commercial Building HVAC Systems

  12. Commercial Buildings (definition) • Buildings shall include, but are not limited to governmental and educational facilities, healthcare, hospitality, institutions, offices, places of assembly, restaurants, retail, and wholesale.

  13. Standard 180 • Purpose • The purpose of this standard is to establish minimum HVAC inspection and maintenance requirements that preserve a system’s ability to achieve acceptable thermal comfort, energy efficiency, and indoor air quality in commercial buildings.

  14. Standard 180 • Scope • This standard provides minimum requirements for the HVAC system inspection and maintenance practice in new and existing buildings. Where specifically noted in this standard, different requirements apply.

  15. What Does the Standard Require? • Written Maintenance Program

  16. Written Maintenance Program • May be hard copy or electronic • Many building information systems will facilitate

  17. What Does the Standard Require? • Written Maintenance Program • Inventory of Components to be Maintained

  18. Inventory of items to be inspected and maintained (4.2.1) • Components of HVAC systems that impact the building’s performance shall be inventoried…

  19. Standard 180 – Airside Components • Table 5-1: Air Distribution • Table 5-2: Air Handlers • Table 5-12: Free Standing Coils • Table 5-14: Fan Coils • Table 5-15: Furnaces • Table 5-16: Duct Free Splits • Table 5-17(18): PTAC(PTHP) • Table 5-20:Rooftops • Table 5-22: Boxes (VAV etc.) • Table 5-24: WSHP

  20. Airside Performance Issues? If so important, why so many: • Air leaks • Infiltration • Air flow volume • Restrictions (filters; coils) • Fans • Dampers • Controls • …

  21. Possible Reasons • Lack of personnel • Training/knowledge • Data • Salesmanship • People not motivated to change!

  22. Standard 180 and Air CleaningKey Tasks - • Check for particulate accumulation on filters. Clean or replace if accumulation results in pressure drop or airflow outside of established operating limits. • Monthly

  26. Couple Training with Resources

  27. Standard 180 and Air CleaningKey Tasks - • Check for particulate accumulation on filters. Clean or replace if accumulation results in pressure drop or airflow outside of established operating limits. • Monthly • Check air filter and housing integrity. Correct as needed. • At filter change • Check integrity of all panels on equipment. Replace fasteners as needed to ensure proper integrity and fit/finish of equipment. • Annually

  28. Standard 180 and Air CleaningOther Related - • Visually inspect grilles, registers and diffusers for dirt accumulation. Clean as needed to remove dirt build up • Simi-annually • Inspect for evidence of moisture carryover beyond the drain pan from cooling coils. Make corrections or repairs as necessary. Visually inspect areas of moisture accumulation for biological growth. If present, clean or disinfect as needed. • Annually • Visually inspect internally lined ductwork until the first turn or up to 20 feet into the supply plenum from air handler for visible biological contamination, and take corrective action. • Annually

  29. Standard 180 and Air CleaningIndicators - • Check for proper operation of cooling or heating coil. Clean, restore or replace as required. • Simi-annually • Check coil fins for evidence of build-up or fouling. Restore if possible. Replace coil if necessary to return to proper functioning. • Annually • Check fan blades. Clean, repair or replace as needed to ensure proper operation. • Annually • Check for fouling, corrosion or degradation. Clean or repair as needed. • Annually • Inspect for evidence of moisture carryover beyond the drain pan from cooling coils. Make corrections or repairs as necessary. • Annually

  31. What Does the Standard Require? • Written Maintenance Program • Inventory of Components to be Maintained • Condition Indicators

  32. Condition Indicators • Performance Objectives • Allowed Variance

  33. Condition Indicators • Appendix A – Performance Objective Examples • Appendix B – Example indicators of unacceptable performance

  34. Inventory - For each component • Task description • What has to be done

  35. TasksVary – Simple to Complex • Visually inspect grilles, registers and diffusers for dirt accumulation. Clean as needed to remove dirt build up • Check control system and devices for evidence of improper operation. Repair, adjust or replace components to ensure proper operation
