Baseline Construction vs. Energy Efficient Construction

The following table indicates a list of prescriptive measures that are considered more energy efficient than standard construction. The comparison between the ”baseline” and “energy efficient” construction may be used to determine the energy savings and rebate entitlement.

Baseline Construction

PowerSense Energy Efficient Construction

Lighting

Fluorescent F32T8 lamps with energy saving magnetic ballast.

F32T8 lamps with electronic ballast.

Fluorescent F96T12, F20T12, F30T12, F40U lamps with energy saving magnetic ballast.

F32T8, F96T8, F17T8, F32T8U lamps with electronic ballast. Other lamp and ballast combinations may also apply (i.e. T5 lamp with electronic ballast),

Standard fluorescent luminaire.

Fluorescent luminaire with deep cell parabolic lens. Linear fluorescent luminaries.

Manual switch controls.

Multi level switching, occupancy sensor or digital controls. Dimmable fluorescent lighting.

Exit sign with mini incandescent lamps.

Exit sign with LED or compact fluorescent lamp.

Incandescent lamp in pot lights, track lights, wall sconce, etc.

Luminaire with hard-wired compact fluorescent lamp (electronic ballast may be required to qualify for rebate). Screw-in compact fluorescent lamps are eligible for a $5 lamp rebate. Other lighting systems such as LED lighting may also be eligible.

Standard metal halide.

Pulse start metal halide.

Little or no day lighting.

Natural lighting: skylights, light tubes, etc.

Heating, Ventilation, and Air Conditioning (HVAC)

Rebate applicable to electrical end uses only – electrical heating, air conditioning and related equipment .

Discrete controls.

Programmable thermostats or DDC -digital control systems - (require appropriate programming to achieve energy savings).

Constant volume (fixed motor speed).

Variable air volume (variable speed drive).

Constant ventilation rate for entire facility

CO2 sensor, demand control or zoned ventilation.

Mechanical ventilation.

Passive ventilation (where appropriate given weather conditions and building design).

Air conditioning unit with SEER of 10.

SEER rating of 12 or higher (10 or higher for split systems).

Standard HVAC configuration (e.g. roof top unit with DX cooling). Electric resistive heat.

• Air source , water source or ground source heat pump (including PTAC units).
• Fan coil system (4 pipe).
• Economizer for rooftop units.

Standard electric resistive heat.

Thermal storage electric heat (apply for Time of Use Rate).

Standard chiller @ 1kW/Ton.

High efficiency chiller @ 0.8 kW/Ton or lower (TBC). Lake Water Cooling

Electric domestic hot water heater. Swimming pools.

Solar or heat pump assisted hot water heating. Refrigerative dehumidification for indoor pools.

No heat recovery.

Passive heat recovery systems – heat pipes, heat wheels.

Lower temperature difference water circulation.

Higher temperature difference to reduce pumping power requirements.

Building Envelope

Rebate applicable to electrical end uses only – electrical heating, air conditioning and related equipment .

Standard thermal pane windows and skylights, etc.

Low E, argon filled, heat mirror, etc. Solar shading systems (awnings, shades, vegetation, trees).

Standard R-value (per building code).

 

Higher R-value.

 

Building entrance with no air lock.

Air lock entrance recommended.

Refrigeration

Constant speed of compresser, fan motors.

Variable speed drive.

Discrete controls.

Programmable thermostats or DDC - digital control systems (require appropriate programming to achieve energy savings).

 

This is only a partial list of the energy efficiency options available. Additional options may be considered on a project-by-project basis.
