1. Proposed Std 180 Standard 52.2 testing
ASHRAE Update
Proposed Std 180
Standard 52.2 testing

2. SPC 180
Standard Practice for Inspection and Maintenance of Commercial Building HVAC systems
Targeted for government bldgs; public bldgs; schools; above three stories
Not targeted for single family residential, industrial, or fabrication facilities
Joint effort with ACCA

3. SPC 180
Purpose – establish minimum Inspection and Maintenance points for three goals
Acceptable thermal comfort
Energy efficiency
Acceptable Indoor Air Quality

4. SPC 180 Makes building owner responsible party
Requires inventory of all HVAC components
Requires a comprehensive plan for intervals with established minimums
Requires documentation of operation
Written in CODE language

5. SPC 180 First review was done 2006
Comments were discussed in Quebec City
Revisions voted on in Dallas
Pre-publish review deadline - 4/30/2007
Will likely go to ASHRAE publishing for 2007
Less than four years since its inception

6. Yes – filter maintenance intervals are in the standard

7. STD 52.2 Two issues of primary interest
Dust Holding capacity
Carries with it Arrestance for MERV 1-4
Conditioning Step
Post review revisions
Working to combine 52.1 and 52.2

8. STD 52.2 MERV 1 - 4 testing There has not been a defined method
Arrestance and DHC language are being brought from 52.1
These values are being defined in 52.2 chart
Note : DHC will be reported for all filters MERV 1-16 with a disclaimer that it is not an indicator of filter life in comparing filters –

9. STD 52.2 Conditioning Step with superfines
Science of effects of diminished efficiency
Two series of voluntary testing of electrets
MERV 16 V-cell
MERV 11 four-inch pleat
Results from labs were similar

10. STD 52.2
Conditioning Step
First review comments discussion in Quebec City June 2006
Revisions made in Jan 2007 – voted to move to publication review ending 4/30/07
Likely to be published by winter meeting

11. STD 52.2 changes in reporting
Conditioning Step will be applied to ALL filters MERV 5-16 electret enhanced fiber or not.
DHC will be reported on test document
Final Pressure drop requirements will be dropped ie: 0.6” ; 1.0” ; 1.4”

12. Merging 52.2 and 52.1
Procedures are underway to remove the two Standard confusion by converging them
52.2 will add the language needed for MERVs 1-4
52.1 will drop “dust spot” from the Standard

13. STD ??
A more complete evaluation of filter efficiency for end user selection
Future – International Standards?
USA is currently a small player in this development
If adopted could use IPA dipping as Conditioning Step
