Ultimately, you are trying to replace multiple components currently used in the building process with this one product so how do the predicted total costs compare? I also am curious about your thoughts on which current building steps could be avoided. It seems that you intend of having these fit between the studs, like insulation would, if this is the case, how will the structural/compressive strength be leveraged? I can see that using this product might prevent the need for plywood being used on the exterior but house wrap would still likely be needed to prevent water from getting in. On the interior, do you see this eliminating the need for drywall? It does not look like the finishing would make for a suitable interior wall from the samples you have created thus far (in addition to the need to cover the studs) so I'm thinking that drywall would still be needed? You say that the insulation value is measured at R16 but what thickness is this at? Would this only work with 2x6 walls to get the needed insulation requirements?

Comparing building costs is a little challenging because lumber and material prices right now are so unstable. 2 years ago I would typically tell people that a hempcrete Z Panel home would cost about 10% more than a standard stick built home with vinyl siding. Currently, the price of a Z Panel home should actually be a little less than standard construction. Z Panels would cost about $27/square foot (of wall) in materials, but less overall for labor. With Z Panels no sheathing is needed, or vapor barrier (house wrap), sheetrock, or insulation. Plaster/render can be adhered right to the Z Panels, that is why no sheetrock or exterior sheathing (OSB/plywood) is needed. Our high density Z Panel has an R value of 16 and is 12 inches thick. Z Panel 2.0 will be more insulative and have an R Value between 22-24 and that will also be just 12 inches thick. These are designed to work with both 2x6 and 2x4 walls. Hempcrete is very resistant to cracking and stress, but it's compressive strength is not superior to concrete. So, in terms of compressive strength and leveraging the current design, the Z Panel adds a little in terms of compression, but adds a LOT in terms of racking and transverse strength to the wall.","author_name":"Zachary Popp","votes":0,"created_at":"2021-08-15T18:50:02Z"}]},{"id":163279,"entity_id":"wefunder:comment:163279","question":"Do you intend to work on this full time?

There are a few reasons why we would build a show/model home in central Wisconsin. This is where our manufacturing facility will be located. It is also where we know we can secure land and subcontractors within a reasonable budget. The main intent of the show home is to demonstrate the aesthetic appeal of a Z Panel home. This will largely be done through videos, photos, and then the associated PR. It is not critical that the home be physically near a large population base. At the same time, we will work with any builder that wants to use Z Panels, and if we could work out an arrangement where they build a home and we use the build to create marketing media, we will absolutely do that. We have had several builders and architects approach us with a desire to use Z panels. So this option has real potential. The next step in our business development is soliciting strategic partnerships with builders/developers. I agree with your thought process. We have already started that, and are pursuing more LOI's. We have found that many builders typically have these two questions: Do Z Panels meet code? When will you be able to deliver product? The funds from this round will help us pursue the ESR/TER to be able to say with confidence that the Z Panels do meet code, along with securing a lease on a manufacturing center. The ESR/TER process has already begun. Now we can say with more confidence that we should be ale to demonstrate code compliance and start production by Q4 2022. That is what strategic partners want to hear. We have had one developer say that may want tp purchase $20-$40 million in Z Panels annually. However, at this point that was an expression of interest and we don't have an LOI signed yet. We are working on that though and traction/momentum is really starting to build.","author_name":"Zachary Popp","votes":1,"created_at":"2022-04-29T13:54:59Z"}]},{"id":202784,"entity_id":"wefunder:comment:202784","question":"Hi Zachary, you mentioned that you will continue to raise funds this year.

If Sativa Building Systems were to sublicense the rights to the Z Panel design, all royalties/profits would be passed through the company, Sativa Building Systems, and any person/entity who shares an equity stake in the company would then also share in those profits.\u0026nbsp; Right now, it is not our intent to sublicense the design. However, if that becomes the best path to get to market, and make the company\u0026nbsp;successful, we will keep that door open.\u0026nbsp; Currently, no other company has the right to use the Z Panel patent besides Sativa Building Systems, and our intent is to exclusively manufacture, market, and sell the Z Panel.\u0026nbsp; \u0026nbsp; We view the building of a model home as a very beneficial marketing and promotional step.\u0026nbsp; The model home will help alleviate\u0026nbsp;any concerns not just about the functionality\u0026nbsp;of a Z Panel home, but also the aesthetics.\u0026nbsp; Our goal is to build a sustainable home that looks beautiful, but conventional, to minimize any stigmas around green/sustainable\u0026nbsp;buildings.\u0026nbsp; As far as timing, since the code approval process has actually been sped up by the recent approval by the International Code Council to recommend\u0026nbsp;hempcrete building be added to the\u0026nbsp;appendix of the International Residential Code (see link below), these steps will likely be flipped.\u0026nbsp; This means hempcrete materials could have code approval\u0026nbsp;as soon as September.\u0026nbsp; Additionally, we have already started the TER/ESR process specifically for the Z Panel, and one way or another, will almost certainly\u0026nbsp;have a product that complies with building codes before the end of 2022.\u0026nbsp; The model home is important, but not as important as code approval.\u0026nbsp; In terms of financing the home, we are exploring multiple paths to ensure this will not be a company expense.\u0026nbsp; One very viable option is a grant.\u0026nbsp; We have applied for a federal grant through the Department of Energy\u0026nbsp;ARPA-E program, and will know in the next few months if this is approved.\u0026nbsp; If we do not get the grant, we will explore other financing options. Either way, our goal with the model home is that it meets these criteria:\u0026nbsp; 1. Be at a minimum cost neutral for the company 2. Provide a substantial promotional opportunity for the company in the construction phase and the completed phase. This means that whoever occupies the home will be willing to allow for viewing/tours etc.\u0026nbsp; I am considering personally funding the home and occupying it, to ensure this happens.\u0026nbsp; Sativa Building Systems will not own the home.\u0026nbsp; Regarding additional fundraising this year.\u0026nbsp; Yes, it is our goal to continue fundraising to get to $500K this year, and potentially beyond. By meeting this initial\u0026nbsp;Wefunder fundraising\u0026nbsp;amount of $125K, we feel very confident in at least completing the Technical Evaluation Report (TER or ESR). The priorities have shifted a little, as we realize that we may need to produce a significant amount of Z Panels for the evaluation\u0026nbsp;report, and therefore\u0026nbsp;purchasing equipment and pursuing\u0026nbsp;manufacturing\u0026nbsp;space is potentially more important than the model home.\u0026nbsp; Even if we get code approval without the evaluation report through the ICC recommendation mentioned prior, we will need to begin manufacturing soon because that\u0026nbsp;means the market opportunity will increase very\u0026nbsp;quickly.\u0026nbsp; So our priorities right now would be facility/equipment, TER/ESR, and model home, in that order. https://ushba.org/hemp-lime-irc-proposal-recommended-for-approval/","author_name":"Zachary Popp","votes":0,"created_at":"2022-04-13T19:49:21Z"}]},{"id":194169,"entity_id":"wefunder:comment:194169","question":"The project that I am currently pricing out is a pole barn or steel building.

Again, I apologize for the delay. Now that I see these questions, I am happy to answer. Here is how the Z Panel is different than compressed straw board or CAFBoard. Those products are essentially a 1:1 replacement for other conventional materials, namely OSB sheathing or gypsum board. They are panelized products meant to cover either the interior or exterior of a wall. The Z Panel is a 4:1 material replacement. It takes place of insulation, gypsum board, vapor barrier, and OSB sheathing. It is not just a wall panel material, it is multifunctional. So, it is different in functionality, but also different in economic potential because building with the Z Panel will eventually not be any more expensive than conventional materials. I do not believe that the strawboard or CAFBoard are truly competitive in price with their conventional alternatives. They may have been for a time, but as lumber prices drop again, they probably won’t be. Our costs should decrease in time as the hemp supply chain gains strength. It's hard for me to speak to how we will scale differently from those specific companies, but I can speak to how I see us scaling differently in comparison to some other hempcrete companies. Our goal is to enter the market soon, and scale in proportion to demand. We are okay with starting small and serving a small demand, knowing that as we gain a foothold in the market, demand will grow as we produce real products and homes, instead of CAD renderings. Other companies are waiting until they have the investments to build manufacturing facilities that cost tens of millions before they even begin production. We are okay with starting with a micro-factory, and potentially establishing many small factories strategically located around the US so serve our customers. Yes, the patent has been issued.

Building with he Z Panels actually retains conventional framing. They are fastened to the studs on each side by the embedded cross-bracing, the studs are attached to the top and bottom plates, and the top and bottom plates are attached to the foundation And the roof. The strength of hempcrete is different than concrete. Concrete is superior at withstanding static compressive loads. Hempcrete is more pliable. We don't see a need to make hempcrete as strong as concrete in the same capacity, because that fact that it is pliable and not as brittle is structurally advantageous. A Z Panel home should perform as well or better than a stick built home in hurricane winds. We will soon be going through testing to confirm that. We have had some interest from large developers in investing in the company, yes.","author_name":"Zachary Popp","votes":0,"created_at":"2022-03-15T01:15:26Z"}]},{"id":186993,"entity_id":"wefunder:comment:186993","question":"I've been searching everywhere for information as to whether anyone has experimented with a combination of hempcrete and hemp graphene.

The portal was not showing me all questions. Hempcrete is not as thick and \"sticky\" as concrete and for that reason I believe that 3D printing hempcrete would be a challenge. Nothing is impossible, but we just don't yet see the practicality in exploring this. There are no pollutants released when cutting the Z Panel. The Z Panel contains only materials sourced directly from the earth, and has no VOC's or harsh chemicals are within it. Having said that, powdered lime is not \"good\" to inhale, and a mask should be work while cutting, although you will see in this video I did not wear one :) https://www.youtube.com/watch?v=g87kyDysC-Q Here is another video showing how an electrical chase could be cut in: https://www.youtube.com/watch?v=MGF87yWO6yg Lastly, here is a video showing how they are installed: https://www.youtube.com/watch?v=SVMItBhc3vA\u0026amp;t=19s I hope that helps!","author_name":"Zachary Popp","votes":0,"created_at":"2022-03-15T01:26:58Z"}]},{"id":164932,"entity_id":"wefunder:comment:164932","question":"Do you plan to manufacture or outsource that?","author_name":"Robert W Neill Jr","votes":0,"created_at":"2021-08-22T19:05:12Z","canonical_url":"https://wefunder.com/sativa.building.systems#question-164932","answers":[{"id":165456,"entity_id":"wefunder:comment:165456","answer":"Right now we are planning to manufacture ourselves.

I have a couple of follow up questions/thoughts. Are the costs you are projecting assuming any kind of economies of scale or would they be for smaller production volumes? Also, how do you see your product working with things that currently occupy some of the wall cavity space, like electrical/plumbing/HVAC? With a traditional set up, the insulation fits around it nicely but it would seem to be quite a bit more challenging with a rigid and semi-dense product like this.

All costs are estimated based on a small production volume of less than 500 Z Panels a day. Large scale production with any automation incorporated would definitely reduce costs, and potentially allow us to lower price points, especially with domestically sourced hemp. Our projections are all based on what we know right now, however production efficiency should definitely improve in the future. As far as other components/materials that occupy the wall space, right now we are testing a Z Panel design with a recess on the interior face to easily place electrical conduit within the Z Panel. Z Panels are most useful for exterior walls, and typically plumbing and HVAC is not placed in exterior walls, so it is mostly electrical we need to accommodate. However, even if you wanted to place something like a vent pipe vertically in a Z Panel, it cuts very easily. It cuts much more like wood than concrete. It would be easy to cut in a recess on the jobsite to place any pipes, conduit, vents, etc.","author_name":"Zachary Popp","votes":0,"created_at":"2021-08-17T02:55:32Z"}]},{"id":163580,"entity_id":"wefunder:comment:163580","question":"Why is your Twitter account private?","author_name":"Jesse Wood","votes":0,"created_at":"2021-08-15T18:21:28Z","canonical_url":"https://wefunder.com/sativa.building.systems#question-163580","answers":[{"id":163690,"entity_id":"wefunder:comment:163690","answer":"Thanks for heads up Jesse.

We work hard to educate people on the differences between marijuana and hemp, and the potential with hemp-based products. Regarding your second question, hempcrete that is maintained and not directly exposed to continuous moisture could last well over 100 years. The Z Panels are used to easily construct a wall. Lastly, we very much see Hempitecture as a complimentary company. Hemp wool insulation in itself does not in itself provide a complete wall system. A home built with Z Panels for the walls and supplemented by hemp wool insulation in the ceiling would be really cool!
