Energy Efficiency in Virgin Island Schools

1. IT STARTED WITH A
“PHONE CALL”

2. IT STARTED WITH A “PHONE CALL”
• Early 2009, it all started with a discussion with Ms. Donna Frett-Gregory
• Introduced her to the concept of Energy Services Companies, (ESCO) and
Performance Contracting.
• Used “buzz words” like;
–
–
–
–
–
–
–
–
–
–
–
No Risk….
No cost assessment…
Paid for from savings….
Single source responsibility….
Guarantees, Guarantees and more Guarantees……
Positive Cashflow…..
Gov’t keeps excess savings…..
Local participation
Economic Development Opportunity
Enhancing the learning environment……
TRUST ME!!!!!!!

3. IT STARTED WITH A “PHONE CALL”
• Ms. Gregory’s response “YEA RIGHT”…..
• Actually she said “we have to get this done”
• DOE gave us a commitment to provide;
– Information, Resources and access to facilities to start
Phase 1 of our discovery effort.
• Mid 2009, ESG received a letter from DOE asking
WAPA to release utility information to our team for a
“utility analysis”

5. IT STARTED WITH A “PHONE CALL”
• Upon conclusion of this high level “Utility
Analysis” we proceeded to Phase 2,
“Technical Analysis”.
– Mobilized team of Energy Engineers to assess
the physical conditions of the facilities.
– Site conditions confirmed that energy related
improvements could be provided thru a cost
effective approach

6. IT STARTED WITH A “PHONE CALL”
• Lighting systems were primarily;
•
•
•
•
•
•
Inefficient fluorescent
High Intensity Discharge (HID)
Incandescent lamps
High Pressure Sodium exterior
Switching was manual
Most exit signs were converted to LED
• Plumbing fixtures were primarily;
•
•
•
•
Toilets, some used up to 4gpf
Urinals, over 1gpf
Hand and Kitchen sinks, mostly without aerators or touch buttons
Showers, some used most not.
• Other observations;
• AC inefficient, bldg envelope not sealed, renewables not active, No bldg
controls, inefficient domestic hot water, Roofs, Insulation, transformers,
Computer Power mgmt.

9. Utility Rates
Phase 1 - M&V savings report calculations use the contracted
baseline rates or the current actual utility rates whichever is
higher.
Electricity
Baseline Rates
$ .2914 per kWh
Current Rates
$0.5500 per kWh
Water
$27.50 per kGal

11. How do We Know
Lighting Retrofit
Phase 1 -Baseline data was established and agreed to for relevant parameters. As examples,
occupancy numbers and hours of operation were established for the schools, and manufacturer’s
data was used to establish the operating characteristics of the different fixture types. As
validation, ESG collected pre and post-construction electrical readings. The results of the M&V
savings report analysis show that the energy savings for the lighting retrofits over the course of
the first full year of operation is as follows.

TOTAL kWh Guaranteed – 2,783,213

Actual kWh Achieved – 2,820,081

12. How Do We Know
Water Retrofit Calculations
Phase 1 Baseline plumbing data was established and agreed to as part
of the contracted energy savings calculations. As examples, occupancy
numbers, hours of operation, and the annual number of flushes (uses)
for each school were established. The results of the M&V savings
report analysis show that the water related energy savings over the
course of the first year is as follows:
 Guaranteed Gallons – 5,952,389
 Actual Gallons Saved – 6,293,389

13. Government of the Virgin Islands
Department of Education
Economic Development and Work Force Development
• Local Spending, approximately 40% to 45% :
– Employee salaries and wages
– Taxes, (GRT) Permits
– Contract supply purchases
– Housing/Warehousing
– Food
– Contractor infrastructure
• Job creation, 27 FTE’s
• On the job training for both installation and post construction for maintaining the
systems. Training is video recorded for new employee orientation and refresher
courses.
• Created intern positions for UVI students to be involved for validating the savings.
• We remain committed to the long term success of the Governors commitment to
job creation and the reduction of fossil fuel dependency by 60% by 2025

15. Has the program been a success?
September 2012 a Survey was sent to the Principals of the TOS 01
schools.
Primary question “Would you recommend the VIEO continue this
program”?
– Woodson Mr. Hewitt = Project has been extremely positive, security cameras can
see areas better at night because of new lights. Teachers feel safer.
– Lockhart Elementary Ms. Sarauw = The staff is extremely pleased. The rooms are
bright and they like the fact of not turning the light switches on and off.
– Lew Muckle, Ms. Wilson-Williams = Yes, a successful program
– CAHS, Joel Buchanan = Yes, Definitely. Real potential towards the contribution of
green systems and energy efficiency
– EBO, Dr. Lois Hassell-Habtes = I definitely recommend this program continue for the
betterment of the learning environment for the children of the Virgin Islands
– BCB, Mr. Carver Farrow = Most definitely, Highly recommend.
