An interview with CAMPout House architect Greg Faulkner on precision, resilience, and wood.
Faulkner Architects have practiced from Truckee, California in the Sierra Nevada Mountain range for 35 years. The firm’s particular approach to design takes inspiration from founder Greg Faulkner’s former work in aircraft design. “Precision is one of the things we’re about,” Faulkner told me. “I was part of the wing group at Cessna. I drew — by hand — the wings and all the parts that make up a wing for the Citation III, the first intercontinental business jet with a low swept wing.” (A low swept wing improves aerodynamic performance.)
Translated to architecture, Faulkner thinks about precision in the assembly of pieces and parts to accommodate for expansion and contraction. He also takes direction from the natural shape and form of the building’s environment to determine materials. “Our work is not just an idea dreamt up separate from the place,” he said.
CAMPout, a Faulkner-designed home located in the Sierra Nevada mountains just 25 miles from where the 2021 Caldor Fire burned through more than 220,000 acres of woodland and destroyed roughly 1,000 structures, perfectly embodies that approach. I spoke with Greg about the story behind the house, designing for fire risk, the virtues of pine. Our conversation has been edited for length and clarity.
Where is CAMPout house located?
Near Lake Tahoe, at the base of a mountain that used to be a volcano and is now carved with ski runs. The house is at a high elevation with a lot of snow and looks south toward that mountain. The house is surrounded by an alpine forest and is in between the mountain and a former prehistoric lake with an all-desert bottom. A spring-fed creek runs through the property.

Tell me about your architectural approach to the house.
For CAMPout, we used unfinished sugar pine trees throughout the interior. You get the scent of sugar pine, and the wood is soft to touch. We used it on the interior walls and ceiling.
We also used a fire-resistant concrete base to create a continuous surface materiality — you have boulders outside, concrete inside and out, and start to get a feeling of inside out, outside in. We wanted to create a seamless experience, using a singular wood species throughout the whole house — it’s not about a different experience everywhere. It’s expedient, and we use what is at hand.
Your Habitable score shows extreme fire risk. Were you aware of this when you built the home? What decisions did you have to make?
We did plan for fire. The exterior of the house is corten steel, [otherwise known as weathering steel, which resists corrosion,] and concrete. There are only these two exterior materials, and both are fire-resistant. Also, we designed an inner courtyard and glazed the exterior windows. The roof has a Class A rating, [meaning that it can withstand intense flames,] and is a combination of heavy plate steel over a layer of stone to protect from flying embers.
In 2021, the Caldor fire came within 25 miles [of the CAMPout property] and destroyed 1,000 structures nearby. In forest fire terms, that’s pretty close. Glazing on the interior glass in the courtyard made that somewhat of a safe room. While the courtyard provided some protection, it still would’ve been very smoky and best to evacuate.
We didn’t have to do too much to create escape routes because there are two ways out of the community where the house is built, in case one is blocked.
Habitable doesn’t have a risk factor for snow and Truckee had record snowfalls last year. How did CAMPout perform in the snow?
Snow is heavy on a roof. CAMPout house is designed for 175 or 200 pounds per square foot — that’s one person standing side by side over the whole roof. But last year we got double that weight in snow; the house had 10 feet of snow stacked on top. We had safety factors built in — we designed the roof to hold the snow in Swiss tradition because of the insulation it provides. Still, that’s a lot of snow.
The water content of snow varies so much. The roof could take a lot of light dry snow, but if it’s full of rain, it might not. Last year the engineer recommended after 5 feet or so to start knocking off the snow. In case another big storm comes, it would be difficult to remove.

Is there anything you would've done differently?
We went back and forth on heating the inner courtyard surface for snow melting. We chose not to do it for sustainability reasons because it takes a lot of energy to heat the outdoors. But with these kind of storms, we might reconsider. Removing snow from the courtyard is difficult even with drains. They have to snow-blow it out, and with 10 feet of snow on the roof, it’s challenging.
What are your three top takeaways for people living in fire and extreme snow zones?
1. You have to make the decision that you are not going to have wood on the exterior of the structure. It’s for more than just fire — building a wooden house in a forest with such extreme weather conditions, it’s a recipe for maintenance. It’s like putting a piece of furniture in the woods and expecting it to survive! You have to look for other materials that can’t burn and don’t need refinishing.
2. Simple forms are best. Complex roof forms and shapes based on aesthetics are difficult to waterproof. Think of 10 feet of snow moving around on the roof. As temperatures changes, snow melts and freezes again. If you have a lot of activity going on in the roof form, it will be difficult. A simple form will keep snow on the roof as insulation.
3. Angled or sloped roofs are not the answer either. What tends to happen is there is a porch at the bottom that ends up holding the snow, or the snow slides onto walkways and driveways and where cars and people and neighbors pass. If you build close to another house, you can’t have the snow slide off and hit the neighbor’s property. Best to keep snow on the roof.

The Loan Programs Office is good for more than just nuclear funding.
That China has a whip hand over the rare earths mining and refining industry is one of the few things Washington can agree on.
That’s why Alex Jacquez, who worked on industrial policy for Joe Biden’s National Economic Council, found it “astounding”when he read in the Washington Post this week that the White House was trying to figure out on the fly what to do about China restricting exports of rare earth metals in response to President Trump’s massive tariffs on the country’s imports.
Rare earth metals have a wide variety of applications, including for magnets in medical technology, defense, and energy productssuch as wind turbines and electric motors.
Jacquez told me there has been “years of work, including by the first Trump administration, that has pointed to this exact case as the worst-case scenario that could happen in an escalation with China.” It stands to reason, then, that experienced policymakers in the Trump administration might have been mindful of forestalling this when developing their tariff plan. But apparently not.
“The lines of attack here are numerous,” Jacquez said. “The fact that the National Economic Council and others are apparently just thinking about this for the first time is pretty shocking.”
And that’s not the only thing the Trump administration is doing that could hamper American access to rare earths and critical minerals.
Though China still effectively controls the global pipeline for most critical minerals (a broader category that includes rare earths as well as more commonly known metals and minerals such as lithium and cobalt), the U.S. has been at work for at least the past five years developing its own domestic supply chain. Much of that work has fallen to the Department of Energy, whose Loan Programs Office has funded mining and processing facilities, and whose Office of Manufacturing and Energy Supply Chains hasfunded and overseen demonstration projects for rare earths and critical minerals mining and refining.
The LPO is in line for dramatic cuts, as Heatmap has reported. So, too, are other departments working on rare earths, including the Office of Manufacturing and Energy Supply Chains. In its zeal to slash the federal government, the Trump administration may have to start from scratch in its efforts to build up a rare earths supply chain.
The Department of Energy did not reply to a request for comment.
This vulnerability to China has been well known in Washington for years, including by the first Trump administration.
“Our dependence on one country, the People's Republic of China (China), for multiple critical minerals is particularly concerning,” then-President Trump said in a 2020 executive order declaring a “national emergency” to deal with “our Nation's undue reliance on critical minerals.” At around the same time, the Loan Programs Office issued guidance “stating a preference for projects related to critical mineral” for applicants for the office’s funding, noting that “80 percent of its rare earth elements directly from China.” Using the Defense Production Act, the Trump administration also issued a grant to the company operating America's sole rare earth mine, MP Materials, to help fund a processing facility at the site of its California mine.
The Biden administration’s work on rare earths and critical minerals was almost entirely consistent with its predecessor’s, just at a greater scale and more focused on energy. About a month after taking office, President Bidenissued an executive order calling for, among other things, a Defense Department report “identifying risks in the supply chain for critical minerals and other identified strategic materials, including rare earth elements.”
Then as part of the Inflation Reduction Act in 2022, the Biden administration increased funding for LPO, which supported a number of critical minerals projects. It also funneled more money into MP Materials — including a $35 million contract from the Department of Defense in 2022 for the California project. In 2024, it awarded the company a competitive tax credit worth $58.5 million to help finance construction of its neodymium-iron-boron magnet factory in Texas. That facilitybegan commercial operation earlier this year.
The finished magnets will be bought by General Motors for its electric vehicles. But even operating at full capacity, it won’t be able to do much to replace China’s production. The MP Metals facility is projected to produce 1,000 tons of the magnets per year.China produced 138,000 tons of NdFeB magnets in 2018.
The Trump administration is not averse to direct financial support for mining and minerals projects, but they seem to want to do it a different way. Secretary of the Interior Doug Burgum has proposed using a sovereign wealth fund to invest in critical mineral mines. There is one big problem with that plan, however: the U.S. doesn’t have one (for the moment, at least).
“LPO can invest in mining projects now,” Jacquez told me. “Cutting 60% of their staff and the experts who work on this is not going to give certainty to the business community if they’re looking to invest in a mine that needs some government backstop.”
And while the fate of the Inflation Reduction Act remains very much in doubt, the subsidies it provided for electric vehicles, solar, and wind, along with domestic content requirements have been a major source of demand for critical minerals mining and refining projects in the United States.
“It’s not something we’re going to solve overnight,” Jacquez said. “But in the midst of a maximalist trade with China, it is something we will have to deal with on an overnight basis, unless and until there’s some kind of de-escalation or agreement.”
A conversation with VDE Americas CEO Brian Grenko.
This week’s Q&A is about hail. Last week, we explained how and why hail storm damage in Texas may have helped galvanize opposition to renewable energy there. So I decided to reach out to Brian Grenko, CEO of renewables engineering advisory firm VDE Americas, to talk about how developers can make sure their projects are not only resistant to hail but also prevent that sort of pushback.
The following conversation has been lightly edited for clarity.
Hiya Brian. So why’d you get into the hail issue?
Obviously solar panels are made with glass that can allow the sunlight to come through. People have to remember that when you install a project, you’re financing it for 35 to 40 years. While the odds of you getting significant hail in California or Arizona are low, it happens a lot throughout the country. And if you think about some of these large projects, they may be in the middle of nowhere, but they are taking hundreds if not thousands of acres of land in some cases. So the chances of them encountering large hail over that lifespan is pretty significant.
We partnered with one of the country’s foremost experts on hail and developed a really interesting technology that can digest radar data and tell folks if they’re developing a project what the [likelihood] will be if there’s significant hail.
Solar panels can withstand one-inch hail – a golfball size – but once you get over two inches, that’s when hail starts breaking solar panels. So it’s important to understand, first and foremost, if you’re developing a project, you need to know the frequency of those events. Once you know that, you need to start thinking about how to design a system to mitigate that risk.
The government agencies that look over land use, how do they handle this particular issue? Are there regulations in place to deal with hail risk?
The regulatory aspects still to consider are about land use. There are authorities with jurisdiction at the federal, state, and local level. Usually, it starts with the local level and with a use permit – a conditional use permit. The developer goes in front of the township or the city or the county, whoever has jurisdiction of wherever the property is going to go. That’s where it gets political.
To answer your question about hail, I don’t know if any of the [authority having jurisdictions] really care about hail. There are folks out there that don’t like solar because it’s an eyesore. I respect that – I don’t agree with that, per se, but I understand and appreciate it. There’s folks with an agenda that just don’t want solar.
So okay, how can developers approach hail risk in a way that makes communities more comfortable?
The bad news is that solar panels use a lot of glass. They take up a lot of land. If you have hail dropping from the sky, that’s a risk.
The good news is that you can design a system to be resilient to that. Even in places like Texas, where you get large hail, preparing can mean the difference between a project that is destroyed and a project that isn’t. We did a case study about a project in the East Texas area called Fighting Jays that had catastrophic damage. We’re very familiar with the area, we work with a lot of clients, and we found three other projects within a five-mile radius that all had minimal damage. That simple decision [to be ready for when storms hit] can make the complete difference.
And more of the week’s big fights around renewable energy.
1. Long Island, New York – We saw the face of the resistance to the war on renewable energy in the Big Apple this week, as protestors rallied in support of offshore wind for a change.
2. Elsewhere on Long Island – The city of Glen Cove is on the verge of being the next New York City-area community with a battery storage ban, discussing this week whether to ban BESS for at least one year amid fire fears.
3. Garrett County, Maryland – Fight readers tell me they’d like to hear a piece of good news for once, so here’s this: A 300-megawatt solar project proposed by REV Solar in rural Maryland appears to be moving forward without a hitch.
4. Stark County, Ohio – The Ohio Public Siting Board rejected Samsung C&T’s Stark Solar project, citing “consistent opposition to the project from each of the local government entities and their impacted constituents.”
5. Ingham County, Michigan – GOP lawmakers in the Michigan State Capitol are advancing legislation to undo the state’s permitting primacy law, which allows developers to evade municipalities that deny projects on unreasonable grounds. It’s unlikely the legislation will become law.
6. Churchill County, Nevada – Commissioners have upheld the special use permit for the Redwood Materials battery storage project we told you about last week.
