Powering the Modern Luxury Home: An Electrical Engineer's Perspective

Every luxury home ColeBreit Engineering designs relies on a web of mechanical, electrical, and plumbing systems working in concert. Senior Electrical Engineer John Pride sits at the center of that web, translating a homeowner's vision and wish list of amenities into a power infrastructure that can support it all reliably for decades. His perspective adds a critical layer to the story ColeBreit has been telling about its luxury residential practice: how the electrical backbone of a high-end home gets planned, sized, and future-proofed from day one.

For Pride, the starting point on any luxury project is arriving at a load calculation that can absorb changes the client hasn't even thought of yet. "That's always the challenging part to start with," he explains. "We have some assumptions where we're starting with code and using the values that they give us. But then we're totaling up the mechanical equipment that we get from the team, and that gives us the general load."

From there, his team digs into the floor plan itself, tallying up laundry rooms, commercial-grade kitchens, pools, EV chargers, and specialty equipment that can push demand well past what a typical home requires. Standard residential service usually runs around 200 amps, occasionally 400 amps for larger homes. ColeBreit's luxury projects are increasingly landing at 600 amps or more. Many of these homes require a shift from standard 240-volt residential service to 208-volt three-phase power, which allows the utility to supply a larger transformer.

Pride emphasizes that getting the size right matters just as much as building in flexibility. "Our goal from the start is to make sure it’s sized appropriately and also scalable for homeowner flexibility," he says, noting that luxury clients often add specialty equipment mid-project. Scalability, rather than a fixed number, is the real design goal.

Resilience planning has become a standard conversation on ColeBreit's luxury projects, particularly for clients in wildfire-prone areas who want to avoid disruption during an outage. Pride's team typically works with a combination of solar, battery storage, and generator hookups, tailored to how the owner intends to live in the home.

"Batteries can get very large and very expensive rather quickly, especially if you're trying to back up the whole home," Pride says. Instead, his team works with owners to define priorities: lighting, refrigeration, heating and cooling for the winter months, or, for some clients, whole-home coverage lasting anywhere from eight hours to several days.

He points out that the answer often depends on how the home functions. "We have clients where it's more of a vacation home versus a primary residence," he says. Because these systems–solar, batteries, and generators–all need to communicate with each other, the main electrical service must be designed from the outset to coordinate all of them, along with manufacturer equipment the team has vetted for reliability.

Lighting design marries engineering and art, and Pride describes his role there as translating a client's or architect's vision into technical reality. "The lighting doesn't always want to be seen," he explains. "It's trying to light specific elements or objects that the owner wants to focus on, but they do not want to draw attention to the lighting source." In other cases, the fixture itself becomes a design feature the owner wants on display.

Either direction starts the same way: gathering the owner's or architect's intent, then presenting a few curated options. "We take that vision from them and do research on our end to provide them the right picture," Pride says.

Technology has expanded what's possible in that space considerably. LED fixtures now come with a wide range of manufacturer-developed optics, giving designers far more control over how light is distributed and shaped than in years past. At the same time, energy codes like California's Title 24 have grown stricter about allowable wattage for specific applications, pushing his team to find creative fixture solutions that meet both the design intent and the code. "California likes to be at net zero or limited energy usage," Pride notes, "and clients want to see that too, because they don't want to see a big power bill."

While ColeBreit typically partners with dedicated low-voltage suppliers for security, networking, and full AV design, Pride's team handles the electrical infrastructure that supports those systems, from automated window shades to home theater and AV equipment rooms. "It's just making sure that the space dedicated for that is large enough for them to put in what they want to support these features," he says, adding that power capacity for these increasingly power-hungry systems must be planned in from the start.

That same philosophy extends to how owners interact with their homes day to day. Modern electrical panels now give homeowners granular, app-based control over individual breakers, solar output, and how battery storage interacts with the grid. Pride sees this flexibility as one of the more rewarding shifts in his work. "The systems now are really customizable to what the owner wants to and doesn't want to control," he says. "We can make it really easy where it's hands-off for the client, or if the owner likes to be more involved, we can make it more robust so they can have all the control that they want."

Fire alarm and life safety systems present a particular design challenge in large custom homes, where clients want protection without visual clutter. Pride's team works closely with manufacturers and ColeBreit's fire protection engineers to find devices that meet code while staying visually unobtrusive. "There are systems out there that have more of the street-looking strobe lights, per se, or smoke alarms where they're not big and bulky right in the center of the space," he says. In sprinklered homes, some detection devices become unnecessary altogether, further reducing visual footprint.

Electrical decisions constantly ripple outward into mechanical and architectural planning, and John offers generator placement as an example. Outdoor placement avoids many of the code requirements tied to indoor installation, including ventilation, fireproofing, and emergency lighting for maintenance access. When outdoor placement isn't an option, those requirements significantly shift the mechanical and architectural scope.

Solar arrays carry similar ripple effects. Roof-mounted or ground-mounted placement decisions require coordination with the structural engineer to confirm the home can support the load, along with mechanical teams to preserve equipment clearances. "That leads us to definitely, if there are any sort of changes down the road, make sure that we're coordinated across all disciplines," Pride says. "Our goal is always to be fully coordinated in the design."

Pride sees the next wave of innovation concentrated in solar, battery storage, and automation. "The biggest changes right now are moving across our solar and battery storage. They're making tons of innovations out there, as well as with controls," he says. He expects artificial intelligence to play a growing role in how homeowners manage their systems, whether through automated controls or owner-directed customization.

The broader trend he's watching is homes approaching true energy independence. "As the equipment gets more robust, we're able to move closer to net zero, where all the power a home uses is also being provided by the solar," he says. "That way, we're not putting any load on the utilities".

Between Kate Hillard's leadership on mechanical and plumbing systems and John Pride's electrical engineering perspective, ColeBreit's luxury residential practice reflects a coordinated approach: every system, visible or hidden, is planned to support how a client actually lives in their home, today and as their needs evolve.
