Lighting Upgrades

Immediate and long-term savings

Public Energy Solutions can cut lighting energy costs up to 60 percent with energy-efficient lamps, ballasts and controls, such as dimming and occupancy sensors. An energy-efficient lighting upgrade can achieve payback in as little as 60 days and provides immediate positive cash flow as well as maintenance and replacement cost savings over the 10- to 20-year life cycles of your energy-efficient equipment.

Services:

Comprehensive lighting energy audit and analysis

Based on a thorough analysis of your building and its lighting equipment, PES documents and recommends profitable investments in conservation opportunities to generate energy savings and operational cost savings.

Energy-efficient lighting upgrade design

As a plan/spec and design/build expert, PES engineers customize lighting system design solutions to optimize specific lighting energy conservation measures that meet your operational needs.

Lighting base load reduction systems can be installed to obtain energy savings by reducing a lighting system’s base load and through curtailment reductions in energy use during peak power demand periods when energy costs are at their highest.

Construction management and installation

PES construction management services ensure successful installation and completion of lighting upgrades on time and on target through the control of quality, cost and time. PES fully integrates estimating, scheduling and expert management throughout the construction process.

Training

PES can train your facility personnel in the operation and maintenance of the upgraded lighting system equipment and processes, ensuring that energy cost savings are achieved and sustained.

Measurement and verification

PES monitors the upgraded system’s performance and verifies the energy savings as an integral part of effective lighting energy management.

Group Relamp

When you outsource your lighting system maintenance to PES, you save money through more efficient planning, maintenance and operation of your lighting system. For example, group re-lamping—replacing all lamps at once, on a planned basis—saves more than 20 percent in labor and maintenance costs compared to randomly replacing lamps one at a time as they fail.

Financing options and rebates

We offer the added value of unique financing opportunities that require minimal or no up-front capital investment. Your agreement can cover all labor and materials, as well as soft costs and purchase options. Financing flexibility and responsiveness can help ensure your project’s success.

PES can also leverage utility incentive programs, when available, including rebates, which can substantially defray the expense of installing energy cost saving lighting upgrades.

Products

Energy-efficient T8 and T5 fluorescent lamps not only reduce lamp energy costs up to 40 percent, but also cut lamp replacement and maintenance expenses due to the substantially longer service life than conventional 40W T12 fluorescent lamps. Using 32W T8 lamps with electronic ballasts (see below) to upgrade a T12 lighting fixture saves in excess of 73 watts per every four-lamp fixture, while producing the same amount of light.

Electronic ballasts start and operate high color rendering, energy-efficient T5 and T8 fluorescent lamps for up to 40 percent savings over traditional lamp/ballast systems composed of 40W cool white T12 lamps powered by standard magnetic ballasts. Because electronic ballasts operate at lower temperatures, they provide additional savings on air conditioning costs. Energy-efficient High Intensity Discharge (HID) ballast/lamp systems provide similar energy cost savings for exterior and high-ceiling lighting.

Automatic and manual dimming controls on a lighting system can provide additional energy cost savings by varying light levels in response to available daylight, task area needs, or to shed electrical load during peak demand periods when utility electrical prices are highest.

Occupancy sensors are lighting controls that detect whether anyone is in an area, such as an office, lavatory or hallway, and then turn the lights on or off accordingly. By using the lights only when needed, an additional 25 to 50 percent energy reduction typically results, which is reflected in your energy bill and ultimately, your bottom line.

Compact Fluorescent Lamps (CFLs) are the typical energy-efficient upgrade for incandescent lamps (light bulbs) which, radiating 90 percent of their energy as heat, have been described as “space heaters masquerading as light sources.” CFLs use about 75% less energy than incandescents and have life cycles up to 10 times longer.

Light-emitting diode (LED) exit signs provide superior illumination for 25 years or more, virtually eliminating lamp replacement and maintenance costs. LED technology provides bright, even illumination, reduces exit sign energy consumption by more than 90 percent and complies with all applicable safety codes and regulations.

Light-emitting diode traffic signals

PES works with municipalities to upgrade signals with light-emitting diodes (LEDs) which burn brighter, have service lives 10 times greater than incandescent traffic signal lamps and use 90 percent less power. This results in dramatic energy cost savings, greater safety and a substantial reduction in maintenance costs.
