1. University of Hawaii at Manoa
Campus / Building Energy Use
Initial Review Discussion
January 6, 2014
Note: Hawaii Energy appreciates the offering of data and assistance from various sources at U.H., please note that this data has not all been verified for accuracy and this first review in this presentation is to be used for the demonstration of the analysis and review methods that could be implemented to manage Energy Use

2. Roadmap for Today Introduction and Overview Roadmap Introductions
Goal of Review
Roadmap
Review of UH System Energy Use Data
Campus Cooling Loops Review
Buildings Energy Use / Weatherization
Heavy vs. Low Use Lab Use Buildings EUI
Usage History Reporting / Source Review
Tell audience to keep in mind that two sets of data were used in order to capture the overall picture of the UH System and the individual buildings within UH Manoa
HECO data from SQL and Individual meter readings provided through a zip file

3. UH Colleges Energy Use
UH Manoa consumes 80% of the electrical usage by UH campuses it has the lowest per kWh blended cost.

4. UH Colleges Energy Use
UH Manoa has the Highest Overall Energy Use Index (EUI) of all UH campuses.

5. Johnson Controls 2010 Report
UH Colleges Energy Use
Actual Usage 2014
EUIs can be used to predict potential for energy savings and verify performance.
Top table has the same data as previous slide but cropped some things to emphasize the relationship between projected energy use to our analyzed energy use
Johnson Controls 2010 Report

6. UH Colleges Load Factor
Overall Demand Density of the campuses in aggregate are below average of Honolulu Office Buildings.
Notice location of new West Oahu Campus renovated CC.
EUIs for these sites too low. Data needs to be reviewed and corrected

7. UH Colleges Student Costs

8. UH Colleges Energy Cost
Constructed by taking total amount billed in a year and divided by annual energy consumption
NOT done by HECO rates.

9. UH Manoa Cooling Loops

10. Cooling Loop Buildings
* Incomplete energy data

11. * Does not include buildings with incomplete data
Cooling Loop Roles
* Does not include buildings with incomplete data

12. UH Manoa Energy Use
The black-tipped bars represent the buildings that are the source of a chilled water loop

13. UH Manoa Energy Use
The black-tipped bars represent the buildings that are the source of a chilled water loop

14. UH Manoa Energy Use
The black-tipped bars represent the buildings that are the source of a chilled water loop

15. UH Manoa Energy Use
The black-tipped bars represent the buildings that are the source of a chilled water loop

16. Year to Year Variance Using EUI
Spring & Fall 14 Increase Usage Appears to be from hotter days with similar
14-15 kWh/CDD relationship as the prior year

17. UH Manoa Lab Use Impact
Benchmarking Analysis of 24 University Buildings in California [Mills and Matthew, 2009]

18. UH Manoa Colleges

19. UH Manoa Building Types
* Higher Education Building Energy Benchmarking Study done in 2004

20. UH Manoa Energy Use
Red boxes – new constructed buildings in respective years
Yellow boxes – notable events
Green boxes – UH Manoa Sustainability Efforts
