Presentation Transcript

  1. System Assessments Planning for Replacement

  2. State On-call Engineers DOUG SVEE Senior Associate, Electrical JARED ROBILLARD Principal, Mechanical

  3. Overview Infrastructure – Identify aging equipment and infrastructure that needs to be replaced, costs and how funding is identified. Discuss gathering information to build plan for what needs to be replaced and when that process should start. Discuss what processes take place for replacement of systems. Is funding currently available, do you need to get funding, how long it takes to scope a project, create construction or permit documents, bid, procure the equipment and get it installed. Discuss the importance of testing, measurement and verification and its role in helping to maintain and plan for system upgrades or replacements.

  5. Planning Replacement– Why/When/What When? Why?

  6. Planning Replacement– Why/When/What When? Why?

  7. What? - Systems and Equipment Systems System Components • Medium Voltage (1,000V to 15,000V) • Low Voltage (50V to 600V) • Telecommunications • Fire Alarm • Grounding • Transformers • Pad Mounted Switches • Feeders • Generators • Transfer Switches • Distribution Equipment • Panels • Voltage (1,000V to 15,000V)

  8. What? - Systems and Equipment Systems System Components • Hydronic Systems • Airside systems • Plumbing systems • Fire suppression • Gas systems • Boilers • Chillers • Pumps • Fans • Air Handling units • Piping, Ductwork, Insulation • Voltage (1,000V to 15,000V)

  9. Information Needed Facility Provided Information Additional Information Systems and Equipment O&Ms Existing Drawings Master Plan Considerations History Trend Data Code/Design Impacts Operation and Service Utility Information Are systems tied to other buildings?

  10. History • Preventative Maintenance Plan • Past Events • Limited Capacity • Available spare parts

  11. History • Maintenance Plan • Water treatment for Hydronic Systems • User input • Known Deficiencies • User complaints • Available spare parts • DDC Controls • Refrigerant Type

  12. History – Age and Life Expectancy • What was the original life expectancy? • Does the equipment have electronics • Yes – Shorter Life Expectancy • No – Longer Life Expectancy

  13. History – Age and Life Expectancy • What was the original life expectancy? • Equipment Location • Outdoors? Indoors? • System Operation

  14. Equipment Life Expectancy Information from Whitestone Guide

  15. Refrigerant Phase Out

  16. Critical for Business Operations • If the equipment fails what are the impacts to operations • Downtime for repairs • Buildings effected

  17. Critical Business Operations • If the equipment fails what are the impacts to operations • Downtime for repairs • Buildings effected

  18. Test Data • What gets tested and What are the tests? • How often do we test and who does the testing? • Single test vs multiple tests with set time between? • Impacts to operations to perform tests?

  19. Test Data – ANSI/NETA MTS • Feeders – VLF vs Direct Current vs Power Frequency • Work with testing agency to discuss what is recommended for your system. Depends on age, equipment cost, etc. • Typically end up being a Pass/Fail and Equipment is De-Energized for 60+ minutes • https://hvtechnologies.com/blog/basics-vlf-testing • Gear - Thermal Imaging, Dielectric Withstand Voltage, Insulation resistance test, Ground resistance test • Equipment needs to be 40% of normal load to detect problems • http://support.fluke.com/find-sales/Download/Asset/3359026_6251_ENG_A_W.PDF

  20. Test Data – ANSI/NETA MTS • Transformers – Oil Filled • Testing of the oil PCB’s vs Degredation. • Physical Tests twice a year, Furan testing ever 2 years (after operating for 5 years) • http://www.intertek.com/ocm/transformer-oil/ • Grounding – Fail of Potential • Impact to operations, requires system to be shutdown

  21. Test Data • Possible Tests • TAB baseline • Water treatment testing • Refrigerant Charge • Who completes Testing? • Equipment vendor Service Techs • TAB Contractors • Commissioning

  22. Impacts on Replacement • New Codes and Safety Features • Expanding campus/ Updated Master Plan • New Program • Energy-intense Enhancements • Energy Efficiency Opportunities

  23. Other Considerations • Study and Planning vs Construction Project • Time required • Design Phase • Bid Phase • Procurement • Installation • System Sophistication • Technology-still supported or being phased out • Migration

  24. Now What? • Prepare Study/Report – What’s it used for? • Evaluate the systems relative to each other • Develop cost to request funding • Identify scope of work for available funding

  25. Evaluation Matrix- Framework

  26. Evaluation Matrix- Framework

  27. The Evergreen State College • Life/ Safety/ Security Assessment • Telecommunications system deficiencies • Medium voltage deficiencies

  28. Bellevue College • 50-year old infrastructure • Expanding campus • Capacity

  29. Skagit Valley College • Expanding Campus • Aged Infrastructure

  30. Tacoma Community College • Expanding campus • Demo building hub to infrastructure • Integrating sustainable technologies
