When you’re a fast-moving electrical contractor, the last thing you want to do is spend 25 minutes painstakingly writing out a load calculation by hand. Just ask Conrad Bianchi.
As the EV Program Manager at Eco Energy Services, Conrad is responsible for managing every part of the company’s electric vehicle charging division — from initial site assessments with customers to permitting documentation. Based in the Chicago suburbs, Eco Energy Services has carved out a niche in both residential and commercial EV installations, bolstered by local utility incentives and rising consumer demand.
“We’re a small team, and I’m the one doing a load calculation for every single house,” Conrad told us. “I used to do them all with pen and paper. It took forever, and there was always the chance of human error.”
That all changed when he discovered Kopperfield.

From paper to permitting in 5 minutes
Like many contractors trying to keep up with growth, Conrad started with a basic need: speed. He was looking for a tool to replace his manual process for calculating electrical loads by hand and knew a digital solution had to be out there. After searching online for a template, Conrad came across Kopperfield.
“What used to take 20 to 25 minutes now takes me five,” said Conrad. “And it’s not just faster — it’s cleaner, more accurate, and way easier to update.”
Eco Energy Services quickly adopted Kopperfield’s load calculator as a core part of their permitting workflow. The ability to generate polished PDFs with professional formatting made a big difference when dealing with AHJs, especially in towns that previously pushed back on handwritten submissions.
“AHJs don’t love handwritten paperwork. They want something they can easily read and file. Kopperfield makes that part seamless.”
Kopperfield’s AI assistant takes things a step further. When Conrad captures a photo of an electrical panel at a customer site, he uses Kopperfield’s AI assistant to quickly extract relevant data and jumpstart the load calculation. This speeds up the process while reducing the chances of overlooking a key load.
“That first pass from the AI gives me a fast framework,” said Conrad. “I tweak it from there, but it’s a huge head start.”
Conrad estimates that he’s saved over 10 hours in just a few months thanks to the speed and reliability of the digital process.
Closing jobs with confidence
Beyond the time savings, the shift to digital has changed how Eco Energy Services sells to customers, as well. With pre-filled standard equipment items built into Kopperfield’s load calculator, Conrad can quickly build a complete calculation at a customer’s home.
“It gives you a realistic idea of what’s in the home,” he said. “Even if it’s not all labeled, the tool gives you a strong starting point so you’re not guessing.”
This helps Conrad close more jobs. For customers who may be wary of upselling or service upgrade costs, Conrad now has a way to clearly show the numbers behind his recommendations.
“If I’m trying to sell a service upgrade, I want to explain why it’s necessary — and Kopperfield helps me do that. It’s not me just pulling numbers out of thin air. I can show them what I’m seeing.”
The results are clear for Eco Energy Services: less back-and-forth, more credibility, and smoother approvals all around.
Faster diagrams for clearer communication
While load calculations are the main reason Eco Energy Services started using Kopperfield, Conrad has also started incorporating other Kopperfield tools into his workflow.
With the single line diagram tool, Conrad can create clear, well-labeled diagrams for complex service upgrades. This helps streamline communication across teams and ensure that inspectors and clients are all on the same page before work begins.
“I used it for a dual meter socket going into dual 200-amp panels on a two-flat project,” he explained. “The AHJ was happy with the clarity of the diagram, and it made things a lot easier for everyone on the job.”
For a team that tackles both residential and commercial jobs, that clarity can go a long way to reducing headaches or rework later.

Staying sharp in the field
In addition to load calcs and line diagrams, Conrad also mentioned using Kopperfield’s NEC chatbot to quickly reference the National Electrical Code. At Eco Energy Services, code compliance is a core part of the business. Every truck in their fleet carries a physical NEC codebook, and the team actively uses them to verify details during installations (in fact, Conrad had his ready to show off when we met for the first time).
Still, even the most experienced electricians appreciate a faster way to search.
“I use Kopperfield’s NEC code reference tool when I need to track down a section quickly,” said Conrad. “It saves me 10 minutes I would’ve spent digging through the index.”
For Conrad and his team, it’s one more way Kopperfield keeps jobs moving: cutting time, not corners.
"You guys make a good tool. I enjoy using it."
For Conrad and the Eco Energy Services team, Kopperfield has become a core part of the workflow, helping them move faster, look more professional, and close jobs with confidence.
“You guys make a good tool. I enjoy using it,” Conrad told us. “It’s saving me time, and I’m looking forward to the future improvements you’ve got planned.”
For a growing shop like Eco Energy Services, working smarter is key. And with Kopperfield in the toolkit, that’s exactly what they’re doing.
