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 dont 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.

8
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.

9
Especially Important

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

11
Impact on Performance

• Adequate high efficiency
• Lacking compromised performance

12
ASHRAE/ACCA/ANSI S-180

• Title
• Standard Practice for Inspection and Maintenance
  of Commercial Building HVAC Systems

13
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.

14
Standard 180

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

15
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.

16
What Does the Standard Require?

• Written Maintenance Program

17
Written Maintenance Program

• May be hard copy or electronic
• Many building information systems will facilitate

18
What Does the Standard Require?

• Written Maintenance Program
• Inventory of Components to be Maintained

19

• Inventory of items to be inspected and maintained
  (4.2.1)
• Components of HVAC systems that impact the
  buildings performance shall be inventoried

Airside Performance Issues?
If so important, why so many

• Air leaks
• Infiltration
• Air flow volume
• Restrictions (filters coils)
• Fans
• Dampers
• Controls

Possible Reasons

• Lack of personnel
• Training/knowledge
• Data
• Salesmanship
• People not motivated to change!

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 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

34
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

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.
