Advanced Mechanical Systems – Finding the Right Solutions for the Client & Project – Mike Godawa

  1. 1. Mike Godawa www.integralgroup.com Advanced Mechanical Systems-Finding the Right Solution for the Client and the Project
  2. 2. Advanced Mechanical SystemsFinding the Right Solution for the Client and theProject• What are the goals of the Client and the Project?• What are the project assets?• What are the project liabilities?• Iterative process matching the potential solutions to the budget and schedule• Final solution• Lessons Learned Case Study: Evergreen Brick Works
  3. 3. Advanced Mechanical SystemsFinding the Right Solution for the Client and theProject• What are the goals of the Client and the Project? Evergreen Brick Works
  4. 4. CLIENT GOALS PROJECT GOALSHigh Sustainability Goals from outset • On Budget • Site wide energy & water • On Schedule conservation • Reduce energy and water • Demonstrate sustainable consumption technologies • Reduce carbon footprint Evergreen Brick Works
  5. 5. Advanced Mechanical Systems Finding the Right Solution for the Client and the Project • What are the goals of the Client and the Project? • What are the project assets? • What are the project liabilities?Evergreen Brick Works
  6. 6. ASSETS LIABILITIES • Good solar opportunities • Location - Flood Plain • Good thermal mass of existing • Contaminated Soils building • Subsurface archeology • Known soil conditions • Historic envelope reduces ability to • Open minded environmentally super insulate buildings driven client • Limited Construction Budget Evergreen Brick Works
  7. 7. Advanced Mechanical SystemsFinding the Right Solution for the Client and theProject• What are the goals of the Client and the Project?• What are the project assets?• What are the project liabilities?• Iterative process matching the potential solutions to the budget and scheduleEvergreen Brick Works
  8. 8. Questions to Ask the Client and the Design Team• Is air conditioning a necessity?• Are there any “sacred cows”?• Is free or waste energy available nearby ?• Do site constraints limit mechanical solutions?• What can drive the mechanical plant size lower?• Are there any opportunities to display new technologies? Evergreen Brick Works
  9. 9. Iterative Design Process • People before hardware • Shell before contents • Application before equipment • Quality before quantity • Passive before active, and • Load reduction before supplyEvergreen Brick Works
  10. 10. Geo-Thermal• Has sex appeal for energy savings but challenge the Owner whether both heating and cooling are required. A balanced load is critical.• Difficult on this site due to buried artifacts, environmental hidden costs and confined location for drilling Evergreen Brick Works
  11. 11. Solar Thermal/PV• Tendered design included a combined concentrated solar thermal/PV on a rotating turntable.• Unfortunately the supplier admitted they had design flaws before it was installed.• System was to provide electricity and hot water for heating, domestic hot water and for cooling through an absorption chiller• Small solar thermal system installed to serve domestic hot water needs Evergreen Brick Works
  12. 12. Bio-Mass Boilers• Tendered design included a biomass boiler in building 16 complete with pellet storage so as to minimize fossil fuel use.• Need a dependable source of cost effective, low ash/low moisture content wood pellets.• Microclimate analysis is critical due to ash content in flue discharge.• Expensive technology and does not necessarily add LEED points for energy but does reduce carbon footprint• As a result it was deleted for cost savings and a gas fired boiler plant including a primary condensing boiler was installed. Evergreen Brick Works
  13. 13. Ice Rink• Seed money for project came from a donor who insisted an ice rink be made.• Waste heat from compressors used to heat radiant floors in Building 14.• Always look for something useful out of mandatory requirementsEvergreen Brick Works
  14. 14. Advanced Mechanical SystemsFinding the Right Solution for the Client and theProject• What are the goals of the Client and the Project?• What are the project assets?• What are the project liabilities?• Iterative process matching the potential solutions to the budget and schedule• Final solution
  15. 15. Stantec
  16. 16. • 765,000 litres of water captured for re- • Energy Intensity 137 KWH/m2/yr. use on site annually: 18 Olympic Pools (494 MJ/m2/yr.) • 60% potable water use reduction • 58.8% Improvement on ASHRAE 90.1 Guideline• 23% Reclaimed and Recycled Materials • 46% Regional materials (800 km radius) • 51% Reduced Carbon The sustainability of Evergreen Brick Works Footprint from ASHRAE 90.1 Guideline
  17. 17. Advanced Mechanical SystemsFinding the Right Solution for the Client and theProject• What are the goals of the Client and the Project?• What are the project assets?• What are the project liabilities?• Iterative process matching the potential solutions to the budget and schedule• Final solution• Lessons Learned Evergreen Brick Works
  18. 18. Natural/Mixed Mode Ventilation• Good solution if whole building does not need to be cooled.• Need to watch out for partitions blocking air paths. Transfer air ducts need to be large to reduce pressure drop• Fan assist runs all the time as building is located in a natural swale.• Improvements needed to be made at solar chimneys as “bounce back” occurred at top level.Evergreen Brick Works
  19. 19. Cisterns• Lots of roof area to capture rain water but how much is too much?• Need to make use of the water. Right now we have two 5,000 gallon tanks to feed water into building 12 for flushing toilets and serve for make- up water for the cooling tower.• Majority of 12 other tanks are to be used for irrigation and have fill spouts at tanks and must be drained in fall to avoid freezing.• Biggest maintenance issue was the leaf catchers which could not handle the flow.Evergreen Brick Works
  20. 20. Modeling• Allow for multiple what-if scenarios.• Get them involved early and before major milestones• Need to have a knowledgeable modeler when doing sustainable design.• Designers must check all assumptions• Needs to be “Green Giant”Evergreen Brick Works
  21. 21. Push the Envelope but make sure there is Clarity with Owner!• Document decisions and Space Conditioning Requirements Building Type Conditioning Summer Indoor Winter Indoor Relative Humidity Approach Design Design (% RH) make it easy for client to Building 1 Fully Conditioned (WB/DB –F) - (DB – F) - - understand (harder than Building 3 (Existing) Unconditioned Ventilation Set Point - 75°F Outdoor Condition Not Controlled it sounds) Building 4 Building 5 Future Heated Only – No - - - - - - Modifications (Existing)• Give examples and Building 6 – 7 Unconditioned Outdoor Condition Outdoor Condition Not Controlled – Nat.
