Sustainable solutions in engineering

1. Sustainable solutions in engineering Introduction of Building Industry in BC Presented by: Philip Fung, M.Sc., P.Eng., LEED AP Tony Tang, P.Eng., LEED AP; Terry Wong, P.Eng David Woo, P.Eng., LEED AP

2. 2 Agenda • Mechanical, Electrical, and Structural Engineering • Technology in Building Engineering • Skills • Current Labour Market

3. 3 Mechanical – Technology in Building Engineering • Big change for the last 25 years. • Not only focus on health and safety (BCBC), but also on energy conservation and environment • From Traditional (CV, VAV, FC, HP) to Sustainable, LEED, Green Building design • Displacement Ventilation, Geothermal system, radiant heat/cool system, heat recovery, natural ventilation, solar system, low (or no) flow fixtures, renewal energy, daylighting, storm water reuse, DDC • Indoor Air Quality (IAQ), Comfort

4. 4 Fan Coil vs. Chilled Beam

5. 5 Radiant Heat/Cool Panel with Light Shelf

6. 6 Heat Pump vs. Variable Flow Refrigerant

10. 10 Mechanical - Skills • Drawings from hand drafting, to AutoCADD, to Revit, BIM • Sustainable verse traditional design skills • Design Build and P3 process • Integrated Design Process (IDP), LEED Score Card • Energy Modeling (HAP, Trace, DOE, IES Energy Plus, EQuest • LEED Acredited Professional • Good Communication Skill

11. 11 Sustainable verse Traditional Design Skills • Sustainable goals set: health, energy, environment • Define Strategies: energy, water, envelope • Concepts: natural ventilation, daylight, low E, solar • Cost Analysis: V.A., life-cycle • Design Development • Contract Documentation: coordinate & document • Tender • Construction Administration • Test & Commission

12. 12 Integrated Design Process • Involves in all disciplines • Participating in environmental goal setting charettes • Developing synergistic solutions that meet multiple needs • Sourcing recycled materials for re-use in the building • Using current proven technologies • Explore the use of energy conservation measures

13. 13 Mechanical – Current Labour Market • 2009 recession • Shortage of senior engineers, and engineers with experience • Lack of sustainable design experience • Foreign trained engineers (prefer having local codes and design knowledge)

14. 14 Electrical - Technology in Building Engineering • Structured Cabling • Office environment networking • Integration of Building Autowork System • Security and Access Control System • High efficiency Lighting • Reduction of power consumption • Controllability • Solar Power

15. 15 Electrical - Skills • 3D Drafting for presentation • Computer modeling for lighting Design • Computer modeling for building power distribution

16. 16 Electrical – Current Labour Market • 2009 Recession • Shortage of senior engineers, and engineers with experience • Lack of sustainable design experience

17. 17 Structural - Technology in Building Engineering • Significant changes in the BC Building Code from 1980 to present, particularly in seismic design • Advancement in computer engineering analysis programs • Etabs • Sap • Softech • Wood program by Wood Council • Suppliers computer programs – EG: Hilti roof deck diaphragm design • Sustainable, LEED, Green Building Design • Requirement of Struct.Eng. registration

18. 18 Structural - Skills • Revit Modeling • Advanced degrees in structural engineering • Continuing Education • Communication

19. 19 Structural – Current Labour Market • Cyclical in nature • Shortage of senior/experienced engineers • Foreign trained engineers
