Energy Savings Performance Contract
(ESPC)
• ESPC is a contract for the identification, evaluation,
recommendation, design and construction of energy
conservation measures, including a design-build contract, that
guarantees energy savings or performance.
• The investment is recouped by the energy savings in time.

Contact Miguel Quinones with the VI Energy Office
Customer completes a USVI WISE application and submits with
supporting documentation
If approved, energy
assessment is scheduled with Quality Electric
Supply
Energy efficiency improvements that save at least 15%
are identified
Customers which contract for
installation within 30 days of
assessment; get the assessment
rebated
Energy efficiency improvements
installed
Installation approval
completed; verification devices
installed
The 40% grant is applied against the
balance for the cost of the
improvement work

Common Energy Conservation Measures
• Air curtains to reduce A/C usage
• Propane substitution for electric
cooking and water heating
• Super high efficiency equipment
replacement for: refrigeration,
cooking, ventilation, air conditioning,
clothes washing & drying
• Switches, timers, occupancy
sensors, and incentives to promote
behavioral changes that reduce
consumption of lighting,
refrigeration, cooking, freezers,
water heating, fans, air conditioners,
and clothes washers & dryers
• LED, CFL, and electronic-ballasted
fluorescent fixtures
• Air filter replacement, sealing
window and air duct leaks, window
shading, etc.
• Water-use efficiencies including
recirculation of waste water, low-
flow showers & toilets, faucet
aerators, and irrigation measures
• Air sealing and building envelopes
• Renewable energy solutions
including PV, solar water heating,
and wind energy generation

Insulated Concrete Form (ICF)
• is a system of formwork for concrete that stays in place as permanent building insulation for energy-efficient, cast-in-place, reinforced concrete walls, floors, and roofs.
• Needs exterior and interior finishing.
• Resistant to hurricanes, also earthquakes if reinforced.

Infiltration
• Infiltration is the unintentional or accidental
introduction of outside air into a building

Energy Efficiency & Renewable

Rent or Own?
Own
• If you plan to keep the home and appliances for just a few years it makes sense to invest.
• The initial investment is steep, but return on the investment is better than keeping the money in the bank.
• Some financial incentives are available: rebates, loans, tax credits.
• The value of the building will also go up.
Rent
• When entering into a lease,
request an energy
assessment of the property.
• When renewing a lease,
negotiate with the landlord,
it benefits both if the usage
is the same.
• Landlords can set electricity
consumption limits for
leases with power included.
