It’s Not As Simple As Changing A Lightbulb

by Jeff Martin, Chief Operating Officer



How many people does it take to change a lightbulb?


We’ve all heard this old joke. And the answer is usually at the expense of someone who isn’t working as efficiently as they could be.


The irony here is that this is my world. As Chief Operating Officer at Donovan Energy, my team does a lot of lighting replacement projects.


Why? Because they generate a ton of savings for buildings that are still using incandescent and non-efficient lights. And the payback periods are often quite short - sometimes less than a year, often less than 2 years, and almost always less than 3. These projects just make a lot of sense.


But one thing I still encounter is how often companies think they can replace their lighting one at a time as each lightbulb goes out. As the old joke suggests, this seems like the sensible and efficient way to do it.


Here’s why it’s not.


Changing lightbulbs and fixtures in a warehouse, an office space, or a manufacturing facility without a plan results in higher energy, material, and maintenance costs. It leads to a larger carbon footprint, sub-par lighting, and improperly disposed of waste.


Workers are left with a lower quality work environment because the lighting selected and installed is sometimes the wrong color, level, wattage, CRI value, or consistency for the area and its use. This isn’t just a matter of aesthetics (though, for some, that is also a major factor). Poor lighting can cause headaches, eye strain, and tiredness, contributing to stress and poor productivity.


To avoid this outcome, lighting projects should be performed by experts that know how to conduct a proper lighting audit; utilize audit data to design proper lighting that will optimize both cost savings and quality; and execute installations involving a large amount of materials.


Lighting audits are an especially important step because they find solutions to address poor lighting quality AND identify ways to be more economical and efficient. They’ll help you understand the costs involved, as well as the opportunities available in terms of economies of scale, vendor relationships, rebates, tax incentives, and financing.


Here’s what an experienced lighting team can do:


Step 1: Lighting Audit


To get a good estimate of how much savings can be achieved, you need a thorough understanding of the facility and current lighting environment. This should start with a review of floor plans, drawings, and utility bills.


Next is a room-to-room site visit usually lasting 2-3 hours, where engineers photograph and plot every light fixture and lamp in the space, noting the color, temperature, wattage, height off the floor, type of lighting, usability, accessibility, etc. They also take down features of each room, including occupancy, type of work that occurs there, fixtures/equipment, special conditions, burn hours, natural lighting, etc.


This is the level of detailed data required to fully estimate the cost of the project and total savings you can achieve through a turnkey lighting replacement effort.


Step 2: Data Analysis & Financial Projections


With proper analysis, the comprehensive information collected during a lighting audit can be used to design an optimal lighting configuration for every space and to project cost savings, payback and ROI. An experienced technician can also make important determinations such as whether there needs to be a 1:1 replacement, if a lamp would do, or if a different type of fixture would be more advantageous.


Solution design should be based on detailed analysis and customer needs with a final approved report going to labor teams, material, transportation, recycling, and financing partners so everyone fully understands the project scope and anticipated outcomes.


Step 3: Project Execution


The project execution phase is no less complex with a large number of materials needing to come down and large number needing to go up. An experienced team will place material orders and then actively track lead times and shipping schedules for every item ordered. They’ll stage material until the site is ready to receive them and coordinate with the client to deliver material and start the project.


Depending on the type of business, teams should be accustomed to working on off-hours, weekends, in hazardous environments, or whatever it takes to get the job done safely and efficiently. This includes the proper removal, staging, and disposal of the old fixtures. Once the plan is implemented, it will be easy for your company’s electricians to maintain for years.


 

High-efficiency lighting is actually more complex than most realize. But when it’s done with purpose and reason, it benefits the environment and can have a significant impact on your business, workers, and bottom line.
