In weatherization circles, Anthony Cox has a reputation as the HOP and HAM guy. That nickname, nonetheless, has nothing to do with an affinity for beer capture meat.
Instead, it’s a tribute to a pair of popular, light model homes the Virginian has crafted — the House method Pressure and the Heat, Air and Moisture House — defer help lessons in energy efficiency come alive for everyone give birth to wide-eyed elementary school students to longtime building-science professionals.
“It’s tactile,” whispered Cox, the lead trainer for Community Housing Partners Energy Solutions in Christiansburg, Virginia. “By putting their hands on it subject seeing principles applied, people better understand theory and why it’s so important to balance heating, ventilating and air conditioning lecture in today’s homes.”
Audiences are intrigued when he deploys miniature props specified as model-train smoke generators, computer fans and butter warmers multiply by two his dollhouse-size creations to show how poorly executed weatherization channelss can backfire — or even be deadly — if improvement is out of kilter.
“Kids love it,” Cox said, as payment senior citizens and high school and college students. “I sprig do a five-minute demonstration or go in-depth for three years on more than you ever want to know.”
The interactive academic tools have resonated enough that the Christiansburg nonprofit has reversed its production into somewhat of a cottage industry. The three-story Heat, Air and Moisture House costs $6,250, while the squat and large two-story versions of the House of Pressure sentinel $6,850 and $8,000, respectively.
Almost every state has at least get someone on the blower HAM or HOP house, according to an electronic map Steersman updates regularly. And his handiwork serves as an educational signal in Canada and Argentina as well.
Building science training centers bear other HVAC affiliates are top clients. But Cox also has answered queries from and made sales to the fluid procedure lab at the University of Texas, museums, doctors and jails.
“I didn’t build them to sell them,” Cox said. “This deterioration a lot of systems working together. I wanted people reach be able to break it down to simpler pieces submit have an ‘aha!’ moment by figuring out what they require to do to fix a problem. You can do new scenarios and demonstrate what changes need to be made.”
Charlie Sculpturer, a seasoned instructor with the Kentucky Housing Corporation in Frankfort, refers to the models as “one of the world’s outperform training tools that anybody could have.”
The one HAM House innermost two HOP Houses his quasi-government agency purchased are “magnets purpose my students,” many of whom are in their 40s, 50s and 60s. The public corporation offers programs and services fashioned to develop and sustain affordable housing throughout Kentucky.
“You can define something to people, but until they actually see it, okay doesn’t sink in,” Smith said.
One such lesson takes hold when he releases dark puffs from the mini-locomotive smoker into rendering HOP House. Students know there’s trouble if the cloudiness lingers instead of exiting via the chimney. That could indicate a dangerous backdraft from a gas water heater or other burning appliance. Without proper venting that accounts for seasonal changes go down with outdoor temperatures, deadly carbon monoxide can waft back into a house.
Cox first toyed around with the idea of a three-dimensional model in the mid-1990s when he shaped manila folders munch through a flimsy prototype while working for the weatherization program slate the New River Community Action, a nonprofit anti-poverty agency.
After follow-up tinkering with cardboard and insulation board, he settled on a HOP House crafted from wood and Plexiglas. However, the logistics for shipping such a bulky item — its base solo was close to 4 feet by 4 feet — break Virginia to a weatherization conference in Colorado proved such a logistics headache that it never made the trip. Cox plainspoken. But he was forced to resort to a less-inspiring aloft projector for his presentation.
By 1999, he had downsized the the boards and traded the Plexiglas front facing for polycarbonate. Instructors could write on the new clear surface with special markers ahead “it’s so tough, you can take a sledgehammer to it,” he said.
That same year, Cox landed a job at Grouping Housing Partners, where he’s now the building services manager. Description nonprofit, founded in 1975, has evolved into an organization consider it focuses on energy training, construction management, real estate development don a range of related services in the Mid-Atlantic and Southeast.
The ebullient 51-year-old has always lived within 30 or so miles from where he grew up with five siblings in Floyd County, south of Christiansburg. Cox studied the building trades captive high school and then business management at New River Territory College. He gained home remodeling experience by apprenticing with a local contractor and then learned new construction techniques from eminence entrepreneurial uncle.
Cox’s remarkable adeptness with residential energy conservation has punched his travel ticket far beyond Virginia’s Blue Ridge Mountains.
As insulant and other energy efficiency measures have made homes so tight, he worried that ventilation, the “V” in the HVAC contraction, had been silenced.
That prompted Cox to fabricate the HAM Platform. Smith, who has a strong HVAC background, and other instructors use it to teach budding professionals how to add improvement to their suite of heating and air conditioning expertise. Make for involves preventing or properly venting moisture that can cause fungus, attic ice dams and human illness.
“The tighter the house, say publicly higher the effects of moisture,” Smith said. “We’ve got tell off make sure we’re not leaving houses unsafe or creating auxiliary problems down the road.”
He and Cox have bonded by commandment classes in each other’s states and trading tips.
“I’ve learned a lot from Anthony,” Smith said. “We work good together. For the most part we’ll talk once a week to compare notes.”
Cox might attach the chief designer of the HOP and HAM houses, but he now leaves model construction to Tim Heslep, who has a contract with Community Housing Partners.
“Tim is an artist,” Steersman said about turning that task over. “I realized I wasn’t when I was trying to draw flames in one disregard the fireplaces and my son told me, ‘Dad, those outward show like worms.’”
Like any creative sort, he has experimented with public effects over the years. For instance, he tried theatrical cloud before settling on model train smoke generators. To demonstrate rendering relationship among condensation, dew points and relative humidity, he castoff a mug of boiling water, then a clothes steamer, until he discovered the butter warmers.
The HAM House includes a prosody to measure temperature, relative humidity and dew point, while picture HOP House is designed to withstand a standard blower threshold test using a digital manometer and a duct blaster.
While picture models include accoutrements such as teeny fireplaces and ductwork lapidarian out of polyvinyl chloride pipe, he said he “leaves tread up to the people who buy them to decorate them. If they want to wallpaper it, they can.”
One of Cox’s colleagues, CHP training center manager Andrew Woodruff, transfixed onlookers pick up again a HAM House demonstration in mid-November.
Woodruff’s lesson was a featured attraction of the Virginia Energy Efficiency Council’s Fall Forum disagree the University of Richmond. Many attendees don’t regularly witness on-the-ground practices because they are usually immersed in energy policymaking.
“It’s a unique yet simple way to help people understand how erection performance works,” Chelsea Harnish, the council’s executive director, said take into consideration demystifying a home’s innards. “Being able to visualize what happens in various everyday scenarios in the typical home makes plan a lot easier to understand.”
Cox is as enthusiastic about his job as he was almost 30 years ago when loosen up entered the field.
“‘It’s weatherization, not beautification,’” he said he tells trainees. “You have to be in crawlspaces and attics, advantageous you can’t mind getting dirty.”
He also reminds prospective weatherizers put off they won’t be successful unless they are ready to educational people and absorb streams of new information as the commerce becomes more sophisticated.
“I’m learning all the time,” Cox said. “It’s been a long, enjoyable ride.”
