PAHS business - thoughts?

Idea - installing PAHS retrofits as a business.
Is it a viable business?
what do people think?

the marketing is awesome -

How would you like total heat security? Never have to worry about running out of wood, oil, electricity going off, etc.
Never pay for any heat again - This passive system collects summer heat, stores it in the earth, and releases it all winter. Works anywhere - even extremely cold climates.
Can be easily designed to keep your home at any temperature you like - year round.
Virtually maintenance free for more than 30 years, probably up to 50.
Costs about the same as a heat pump, but with zero operating costs and no technical equipment.
Provides air exchange continuously.
Proven system.

Great idea and I'm sure there would be unlimited potential. You might have to do some serious marketing since it is not well known but sounds like you have a good start. I really love the PAHS concept but I don't like the plastic and foam insulation that goes along with "conventional" PAHS haha. I had a thought of installing heat tubes underneath large warehouse type structures like walmarts, shopping centers, even parking lots, etc. This would have to be done at the initial build, not a retrofit, but think of it. All that thermal mass goodness. your umbrella is already a part of the build, not an additional expense. Acres and acres that could be tapped into so easily. I figured if I pushed my idea and had a little credibility, it could turn into quite the business. Of course, I don't exactly supports these types of mega buildings in the first place but I'm sure there could be a good morally sound place for my idea somewhere.

It depends on how good you are at sales. There are so few examples, let alone successful examples, of PAHS construction, you will have to do a lot of convincing.

Applying PAHS elements to an existing structure can be problematic. I assume that by retrofitting you are referring to extending a PAHS umbrella around the foundation and perhaps adding berms of some kind? To get the optimum coverage, you would basically be removing all, or nearly all, existing landscaping (including driveways and other pavement) on a standard suburban lot and probably doing some deep trenching at the perimeter on the short sides. You will need to prove, unequivocally, that it will be worth it. There shouldn't be any code issues with putting in an umbrella, but the berms may face setback, visibility and egress restrictions and will likely need an engineer's stamp.

Nothing sells like success. Do two or three successful projects, and no spectacular failures, and you won't have too much trouble getting customers.

As in any business venture, there is no guarantee of success.

Do your homework and good luck.
