U.S. Primary Energy Consumption by Source and Sector, 2007 (Quadrillion 1015 Btu)

Energy Information Administration, Annual Energy Review 2007

Electricity is ~40% of Energy

More site electricity is consumed for

lighting than for any other end use.

Typical Building $$$ Opportunities

• Lighting upgrades

– Upgraded Retrofit or New Technology

– New Controls

• Building management

– Daylight harvesting

– HVAC integration

• Motor replacements

• Utility systems

– Compressed air

• Power factor improvements

Types of Lighting

• Standard fluorescent – Mixture of low pressure mercury vapor and inert gas (such as argon) in tube. Phosphor powder

coating on tube fluoresces excited by UV emitted by mercury vapor when current applied. Current controlled by a ballast.

• Compact fluorescent – Same technology as above

• Incandescent – Nitrogen and or argon filled, ~5-10% of power converted to light

• High intensity discharge (HID) – Mercury vapor, metal halide, and high pressure sodium lamps

• Halogen – Halogen gas-filled (iodine or bromine) quartz capsule operated at high temperature

• Light Emitting Diode (LED) – Semiconductor diode that emits light when electrical current passes through it, solid state device.

Process to Economically Retrofit Older Buildings

• Identify facilities with older lighting installations – T12 or T8 fluorescent and halogen or incandescent spot based

• Carefully audit the facility – Listen to occupant and review lighting and lighting control design – Measure light levels vs. recommended and statutory requirements – Collect operational cost and building use information – Identify opportunity!

• Model and develop an improved overall lighting strategy

– GOAL: Deliver the highest quality people environment while optimizing operational costs

• Propose a new lighting solution, conducting a trial if appropriate – Identify key benefits and ROI

• Help Customers secure federal, state and other rebate funding to make improvements

even more affordable.

• Manage effective turnkey installation and commissioning.

• Verify Savings and Benefits – Sometimes needed to secure rebates

• Manage recycle of old lamps.

Core Lighting Retrofit Strategies • Replace T12 with T8 or even better go to T5

– ~50% of the power consumption for same lumen output

– Longer useful light output (lumen maintenance)

– Reduced phosphor, mercury (< 3 mg) and recycle content

• Replace T8 with T5 – ~13-17% energy saving with same lumen output

– Reduced phosphor, mercury (< 3 mg) and recycle content

– Small lamp uses fewer resources and energy in manufacture

• Retrofit MIH with HO T5 (typical 465 W MIH fixtures retrofit with 234W HO T5) – ~50% energy savings with similar lumen output

– Long lamp life (20,000 hours) minimizes maintenance cost

– Reduced warm-up time

• Retrofit Incandescent, Halogen and CFL Spot with LED and dimmable LED – ~50-80% energy savings

– Light Quality

– Reduced halogen and other gas, heavy metal and recycle content

• Deploy occupancy sensors in low traffic areas – Warehouses, Storage

• Consider “Daylight Harvesting” techniques in suitable buildings – Shade control, intelligent dimmers

Pharmaceutical Packaging Example • Reduced total power consumption:

– From 595 MWh/yr to and estimated 132 MWh/yr, saving approximately $32,000/yr in operating costs from lighting and a further $4,000/yr from HVAC.

– Reduce facility Carbon footprint by ~300 tons CO2 equivalent/year

• Reduced maintenance expenditures (not estimated) due to:

– Longer lamp life

– Simpler stocking for entire facility

– Lower skill labor for tube replacement

• Comparable to today lighting levels in all key areas with lighting output sustained at a higher output for the life of the bulb when compared to existing MH units

• Occupancy sensors for maximum efficiency (selected areas)

• Improved employee satisfaction due to enhanced workplace light levels

• Proposed implementation plan for minimal disruption of operations

• Annual power savings alone implementing the Sitka solution of: ~$32,000/year

Simple payback for this project is <24 months based on 2010 power rates
