  1. Operations and Maintenance in Standard 100 Cedric S. Trueman, P. Eng. Life Member ASHRAE Trueman Engineering Services Victoria, BC, CANADA

  2. Context of Revision to Operations & Maintenance Requirements For compliance – Meeting O & M reqt’s will be mandatory Std. 100: Will be written in code language Available for adoption by code authorities

  3. Challenge for Revision • How stringent do we make requirements? • The Standard could be adopted as code. • If so, it would define the worst O & M program permitted • Thus requirements will need to be: • feasible for buildings of all sizes and occupancies, • practical for the average owner, and • achieve energy efficiency

  4. Options for Stringency • Leading edge best practice - optimum for energy efficiency, but not reasonable for a minimum code • Best practice - suitable for a Guideline, but demanding for a minimum code • Good practice – minimum that should be required • Minimum existing practice – not acceptable Operations & Maintenance in Standard 100

  5. Goal for Revision – Good Practice • In all aspects of operations and maintenance • Focus on actions that will impact energy efficiency

  6. Scope of Operations and Maintenance Requirements • O & M Plan, covering: • Basic energy management actions, • Building energy monitoring, • Energy management plan, and • Maintaining energy efficiency • Applies to all building systems

  7. Building Systems Included • Building Envelope • Domestic Hot Water, including solar thermal • HVAC –covering a range of HVAC systems: • Boiler & chiller hydronic systems, • Airside systems – unitary, single & multiple zone, terminal systems • Heat recovery • Evaporative cooling • Thermal storage • Geo-thermal

  8. Building Systems Included (cont’d) • Refrigeration – for non-comfort cooling applications – display cases, walk-ins, secondary systems • Lighting – interior, exterior, daylighting • Controls – pneumatic, analog, DDC • Power Generation and Distribution Systems • Generation limited to on-site – e.g. wind, PV, etc.
