The 2021 Marshall Hearth destroyed virtually each home within the Sagamore subdivision in Boulder County, Colorado. It was essentially the most harmful hearth in Colorado’s historical past by way of property loss. These weren’t lavish homes—designer Andrew Michler described them as “strong center class.”
Michler is a Passive Home designer whose personal Colorado home has been coated in Treehugger. He teamed up with Seattle-based architect Rob Harrison—seen strolling by Susan Jones’ home in Seattle—and native builder Chuck Bower of Joubert Houses to supply the Restore Passive Home to residents who misplaced their properties within the hearth.
It is a very attention-grabbing dwelling for numerous causes, not the least of which is that it’s out there as a predesigned, pre-priced package deal for $550,000 after a bunch of presidency incentives for constructing environment friendly all-electric properties. That is not excessive for a 1,750-square-foot home with a full basement.
Joubert Houses tells Treehugger that one other builder priced out an Power Star home of about the identical measurement at $100,000 extra. It’s constructed with “firewise” building utilizing non-combustible cladding and roofing, triple-pane home windows with tempered glass, and no overhangs that fireplace and wind can get underneath.
The design is straightforward and simple. The corporate mentioned, “We took our design cues from Colorado mining vernacular structure, a easy cross-gable type you would possibly see in early 20thcentury Colorado small cities.” Simplicity is essential in a Passive Home design; each jog and bump can flip right into a “thermal bridge,” growing warmth loss in addition to constructing prices.
I typically use architect Bronwyn Barry’s hashtag #BBB—boxy however stunning—to explain Passive Home designs with easy varieties, however this one is not so easy. It’s L-shaped, which will increase floor space.
Nevertheless, there are benefits. It permits the home to stay out in entrance of the storage as a substitute of getting that horrible snout home look. After I complained concerning the storage, Harrison mentioned they’d have most well-liked to do an entire new web site plan with garages within the again, however it will have added years to the mission, provided that the positioning plan and the zoning is all in place.
Harrison additionally tells Treehugger that it creates 4 roof planes dealing with in numerous instructions, to allow them to web site the home on any lot with any orientation, and nonetheless have numerous roof dealing with south for photo voltaic panels.
The Colorado Public Radio Information covers the home in an article with the ridiculous title: “This climate-friendly home for Marshall hearth victims is not a luxurious dwelling.” What’s not luxurious a couple of draft-free home that’s comfy in all places, with nice indoor air high quality, no mud, and no noise from outdoors? I’ve really referred to as Passive Home a normal of luxurious.
RESTORE Passive Home
The plan definitely seems to be luxurious to me, with its beneficiant kitchen and a “media room” with a full toilet on the bottom ground as a result of they’re “adaptable for these with short-term or persevering with mobility points. It’s at all times good to have one bed room on the bottom ground.”

The second ground seems to be fairly luxe too, with each bed room having the opportunity of pure cross-ventilation and entry to decks.
The home is all-electric, with two mini-split warmth pumps doing the heating and cooling—you do not want a lot of both in a Passive Home—and a Dutch warmth restoration air flow system delivering recent filtered air. There’s an induction range, a warmth pump garments dryer, and a warmth pump water heater.
RESTORE Passive Home
Michler constructed his personal home to be as near foam-free as potential, and whereas this home is just not marketed as a “wholesome home,” it is fairly near plastic-free, with wooden flooring (no vinyl), ceramic tile on the flooring within the loos and entry, high-quality cabinetry, painted wooden sills and drywall wraps for the home windows, strong floor counter tops, and LED lighting. Passive Home designs are typically more healthy by their very nature; there are not any drafts, no condensation on home windows, far much less probability of mould, dry heat basements, and most significantly, repeatedly managed air flow. Being all-electric, there are not any nitrogen oxides or carbon monoxide from gasoline stoves and home equipment.
RESTORE Passive Home
The home is described as “an ultra-high efficiency various to different choices for rebuilding that shall be comparable in worth to traditional building however present an unparalleled stage of consolation and long run power financial savings.” That appears like luxurious to me.
Based on the NOAA Local weather web site“as a result of the danger of drought and heat extremes are growing because of human-caused world warming, it’s cheap to suppose that world warming contributed indirectly to the devastation brought on by the Marshall Hearth.” Others are extra definitive. “It’s the primary time in my profession I’ve felt comfy saying it is a local weather hearth,” mentioned Natasha Stavros, director of a laboratory on the College of Colorado that focuses on multidisciplinary science issues.
Rebuilding with all-electric passive home designs is an applicable response to coping with local weather change; they don’t immediately emit greenhouse gases and cut back oblique emissions through the use of a lot much less electrical energy. There was evidently loads of resistance to inexperienced constructing codes after the fireplace, as a result of folks apprehensive that it will add prices, however because the Restore workforce demonstrates, it does not have so as to add upfront prices in case you do it proper, and it’ll dramatically cut back working prices. Let’s hope that they construct a complete subdivision of them.
