Because a prototype structure that uses the IPS system has never actually been built as to date, it is very difficult to determine what the cost of any IPS structure would be at this time. To add, prototype costs are misleading, because prototypes are always expensive. However, because of the “bare bones” efficiency of the IPS system, after a prototype has been built, it is quite likely that the system would prove to be the most cost-efficient durable building system on the market. Of course, it is always important to remember that, whatever the cost of this system comes out to be, with regard to any product, people get what they pay for. And in the case of the IPS system, owners could be assured that they’ve built themselves a building that could be handed down through multiple generations, that would endure the most severe outdoor environmental conditions throughout those generations
