ASHRAE has new compliance path for energy Standard 90.1


The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) and the Illuminating Engineering Society (IES) have a new optional third path for compliance with their energy efficiency standard. The move provides more flexibility for the industry.
Standard  90.1-2013 Appendix G: Performance Rating Method, is an excerpt from ANSI/ASHRAE/IES Standard 90.1 (I-P), Energy Standard for Buildings Except Low-Rise Residential Buildings. The document gives users immediate access to selected addenda due to be published in the 2016 version of the standard.
The majority of the document is comprised of addendum bm, which allows Appendix G to be used as a compliance path within the standard.

Meanwhile, the Air-Conditioning, Heating, and Refrigeration Institute (AHRI) has praised ASHRAE’s approval of Addendum d to ASHRAE Standard 62.1, Ventilation for Acceptable Indoor Air Quality, which states that systems including chilled beams are not required to use a filter. The revision will be published in the 2016 edition of the standard, which is expected to be published this October.
The addendum adds an exception to Section 5.8 of the standard, which currently requires particulate matter filters or air cleaners for all cooling coils or other devices with wetted surfaces. The AHRI Chilled Beams Product Section submitted a recommendation for this addendum because sensible-only chilled beams would not require filtration for wetted surfaces, as the coil surface would never be wet. ASHRAE agreed, and therefore the 2016 edition of Standard 62.1 will include the exception for cooling coils that are designed, controlled, and operated to provide sensible cooling only.
