Master List of Onboard/In-Field Fault Detection and Diagnostics (FDD) Technology Offerings (2017)
The FDD Committee developed a FDD Technology Master List of the different FDD offerings that assist in identification of performance, maintenance, or repair needs using measurements and software intelligence in an in-field or onboard fashion. They also also developed well-defined criteria for inclusion in the different categories to simplify the process and be able to better compare technologies.
Recommendation to Qualify FDD Technologies for Inclusion in Utility Commercial HVAC Programs (2017)
FDD technologies have much potential to improve HVAC Commercial Quality Maintenance (CQM). This deliverable captures key elements on how FDD can better fit in with the CA statewide CQM programs. It touches on different strategies for implementation and qualification criteria to consider. This document will be updated.
Implementation and Value of Commercial HVAC Quality Maintenance Based on Standard 180 (2017)
Implementation of ANSI/ASHRAE/ACCA Standard 180 requires a dialog between the responsible party (owner/representative) and the service provider/contractor in order to develop maintenance plan goals, metrics, processes and program revisions/improvements. This document suggests topics and a sequence of questions which these two parties need to explore and discuss together in order to establish a Standard 180 based maintenance program. The interview process is also intended to uncover the significant benefits of this approach to maintenance - the "value proposition." Future work is planned to provide clearer guidance on how this interview process might be implemented for each party.
Development of a Standard 180 User Guide for Commercial Maintenance (2017)
ANSI/ASHRAE/ACCA Standard 180 for commercial HVAC maintenance provides requirements written in "standards" enforcement language. The standard addresses "what" is required but not sufficient guidance on "how" those requirements might be met or implemented by responsible parties (owners), their service providers or utility program designers/implementers. This document provides input from HVAC industry subject matter experts to address several key topics which need to be understood in order to implement the standard. It also includes suggestions for revisions to the current 2012 standard for Standard 180 Committee consideration. The working group plans to continue work on identified topics to develop a user guide draft.
