  1. BCIT NE01 Energy Upgrade and Retrofit Study Result Summary

  2. Introduction • Transsolar Goals for Study: • Understand the NE01 building and assess its current state • Analyze the climate situation to drive passive design strategies • Engage students and faculty for feedback and idea generation through a workshop • Investigate potential for comfort improvements in the space and energy reduction • Develop an energy strategy to meet the ambitious Factor Four goals

  3. Building Understanding • HVAC System • All-air Conditioning System • Centralized Air Handling Units • Air Recirculation • Centralized reheat coils • BCIT district heating supply with back-up local gas boilers

  4. Building Understanding Lighting

  5. Creating a Base Case Adjusted Energy Consumption for Comparison Calculated values

  6. Creating a Base Case * Simulated values *without lighting or plug-loads

  7. Building Understanding Current Thermal Comfort Level

  8. Base Case Thermal Comfort Level

  9. Interventions

  10. Intervention Evaluation Evaluation Matrix – Façade Affected Interventions

  11. Recommendations • NE01 Building Upgrade Strategy: • Building-Wide Ventilation: Split HVAC with Natural Ventilation • Façade Improvements • Integration of Heat Recovery in Ventilation System • Lighting Upgrades • Additional Interventions

  12. Recommendations • Building-Wide Ventilation: Separation and Natural Ventilation • Radiative conditioning system • Dedicated outdoor air ventilation system (driven by air quality not heating) • Natural Ventilation through installation of operable windows along facade

  13. Night Flushing Effect – Transsolar Office Effect of opening windows

  14. Recommendations Thermal Comfort Level With Split HVAC and Natural Ventilation (incl. nighttime flushing)

  15. Recommendations • Façade Improvements • Double Glazed Windows with High Quality Frame • Internal Insulation Addition

  16. Recommendations • Integration of Heat Recovery in Ventilation System • Heat Recovery Installation in Central Air Handling Units • Unit-by-Unit Investigation to determine best heat recovery solution

  17. Recommendations Final Thermal Comfort Level

  18. Recommendations • Lighting Improvements • LED Lighting in common spaces (bathrooms, corridors, etc.) • Occupation and Daylight controls in common spaces • Vacancy controls in offices and classrooms

  19. Additional Interventions • Natural ventilation and shading in cafeteria atrium space • Replacement of hot water systems for bathrooms with electrical instantaneous hot water heaters

  20. Recommendations

  21. Recommendations Energy Reduction Potential

  22. Thermal Simulation Weather Data Validation
