Lighting system retrofits offer a
cost-effective and environmentally responsible way to upgrade lighting systems,
consequently leading to significant energy savings, reduced maintenance, and
improved lighting quality. EnerNexus performs design and specification of
lighting system retrofits in response to the implementation and completion of
our investment grade (ASHRAE Level III) Audit.

A lighting system retrofit
involves upgrading existing lighting systems with newer, more efficient
technologies, often focusing on replacing older bulbs, previous generation LEDs
with current and next generation LEDs. This can include upgrading controls like
dimmers

and motion sensors, circadian effects, integration of Network Lighting Controls
(NLC) and HVAC into Building Automation and Building Management Systems, to
maximize energy efficiencies and savings. The main goal is to improve energy
efficiency and reduce long-term costs, while also potentially enhancing lighting
quality and improving employee productivity.

What it is:

• Deploy data loggers to determine and extrapolate
  space occupancy to accurately quantify when and how longer fixtures are
  energized.
• Pinpoint existing light levels for space
  application compliance.
• Replacing components: Retrofitting involves
  replacing parts of an existing lighting system with more efficient or
  better-quality alternatives.
• Turnkey installation project management, punch
  listing, commissioning, and training of your new LED and Controls Systems.
• Focus on efficiency: The primary aim is to reduce
  energy consumption and lower associated costs.
• More than just bulbs: While replacing
  bulbs with LEDs is a common aspect, retrofits can also include upgrading
  controls, fixtures, and even entire lighting systems.

 Why it is done:

• Energy savings: LED retrofits can
  significantly reduce energy consumption and related costs.
• Reduced maintenance: LEDs have a
  much longer lifespan than traditional bulbs, leading to fewer replacements
  and lower maintenance costs.
• Improved lighting quality: LED
  retrofits can provide better color rendering and light distribution,
  enhancing the aesthetic appeal and functionality of a space.
• Health, Safety and productivity: Better
  lighting can improve visibility and safety, circadian rhythm, potentially
  increasing productivity in some applications.

Benefits:

• Cost savings: Reduced energy consumption
  and maintenance costs can offset the initial investment.
• Environmental benefits: Energy
  efficiency contributes to a smaller carbon footprint.
• Enhanced aesthetics: Modern
  LED lighting can significantly improve the visual appeal of a space.
• Improved functionality: Better
  lighting can enhance visibility, safety, and productivity in various
  settings.

Examples:

• Office buildings: Replacing fluorescent
  fixtures, previous generation LED with next generation integrated,
  energy-efficient LED conversion kits and fixtures.
• Industrial facilities: Upgrading
  lighting to improve safety and efficiency.
• Parking lots: Installing LED lights to
  improve visibility and safety.
• Residential homes: Replacing
  incandescent bulbs with “smart” LEDs.

 Considerations:

• While there is an upfront cost, the long-term
  savings often make it a worthwhile investment.
• In some cases, fixture modifications may be
  necessary to accommodate new LED technologies.
• Integrating and Network Integration of smart
  controls like dimmers, daylight harvesting, solar tubing, and motion
  sensors can further enhance energy efficiency and functionality.
