  • HTM, sustainable, natural zero-energy passive solar housing in the 'earthship' earthome style. The basic design of our high thermal mass HTM™ sustainable housing, passive solar design is presented in the earth home style, but can be easily molded to fit your family's lifestyle and personal preferences, especially the exterior appearance. The open floorplans of our natural, sustainable, earthhome design can be boxed in later for storage, quiet areas, and sleeping spaces. Just keep in mind that as you section the home off, the need for supplemental heat and light is only going to increase. This is the basic nature of low-tech, mechanical-system-free passive solar architecture. Striking a balance between aesthetic desires and passive functionality is key with any truly sustainable design.

  • With full floor to ceiling glass, the view is endless and allows passive solar heat gain and natural light to penetrate deep into every room. The front South 'hallway' combines with the planterbed to create a very open, airy feeling throughout an HTM. As we will discuss in later chapters, you can box an HTM in to create smaller rooms, but this is easily and best done after the home is completed since interior partition walls are non-bearing. The main thing to keep in mind is the sustainable, energy independent nature of your HTM will be affected by cutting the home up into smaller boxed-in rooms. You are in-effect bit by bit turning an HTM into a conventional home. True, it will still function worlds better than any stick framed home, but it may need more supplemental energy and mechanical systems to heat and cool interior rooms that passive solar energy has been prevented from entering directly.

  • The living and kitchen areas are often shared by the front entry room. Please note the lack of doorways and windows. This design feature is what makes a standard HTM so adaptable to underground home and fully bermed layouts. You really don't need doors and windows along any but the south wall in a heating climate. You are, of course, free to design your HTM with doors and windows on all four exterior walls, but by concentrating all of the glass and doors along the south wall, you simplify and speed construction, saving money on building costs while maximizing thermal mass and functionality.

  • Middle rooms are left open for use as living rooms and office areas or boxed-in for bedroom privacy. Utility, storage areas, and bathrooms are typically arranged along the rear North wall with clerestory windows or skylights supplying plenty of warm natural light. As you can see, wall treatments are more varied than just stucco, it is just that stucco and plasters are the natural choice with drystack block. Floor treatments are the most varied of all since just about anything goes in an HTM. Naturally, dark tile absorbs the most solar gain, but the immense amount of thermal mass allows you to choose carpet or hardwood floors for many areas of the home with little drop in overall performance.

  • The master suite is typically an end room for the sake of privacy. Water tubes, glass block walls, drapes, or moveable partitions can be installed for additional privacy and a door can naturally be added to the hallway. These are all personal taste issues that are hashed out during the design stage as you take a closer look at lifestyle and family needs.

  • Please note the nearly flat front roof section has a minimal 1/12 pitch to better catch snow for a 'thermal blanket' effect. In cold climates, snow on the roof acts as an extra layer of insulation for protection against the elements. This 1/12 pitch flat roof design has the additional benefit of preventing snow from falling off the roof and onto your glass and gutters. The perimeter of the roof is the first to begin melting when it warms up, so gutters are very easy to maintain without need for heat tape in most all climates. Irrigation re-use of the snow is another design consideration: as the snow slowly melts, it can be directed to interior planterbeds where the tomatoes are still blooming like crazy.

  • Exposed purlin log vigas are a common south-western touch for HTMs. Design considerations include installing copper sheeting atop the exposed log vigas to ensure they do not rot and chinking cracks in the logs carefully to ensure home is kept as airtight as possible. Exterior fascia wall finish can be anything you want... vinyl or metal siding, logs, stone, brick, cedar shake, hardiboard, or whatever. Stucco coating is shown here and is standard practice for many clients due to its economy, inherent longevity, and maintenance-free convenience. Natural plasters can just as easily be used, but with a much larger eave overhang to better protect the plaster finish from rain damage.

  • Shade cloth is often used in an awning to block excess solar heat gain. Wing shading as shown here is an option, but it is more common to see a standard horizontal trellis with shade atop, like a pergola. Notice the line of shade as it extends a foot past the windows' bottom. Shade cloth is available from us in assorted colors and choice of shade protection factor to make custom designs for individual climates possible. Proper shade cloth layout is one of the keys to any workable, functionally passive sustainable design. In addition to blocking direct solar gain, shade cloth creates a micro climate around the perimeter of the home dramatically affecting the comfort level inside.

  • The front hallway of an HTM doubles as planterbed access, really opening these rooms up! Light and airy is redefined with an HTM design. These homes have a feel and personality that is totally unlike a conventional stick-frame home. The combination of subtle radiant heating and cooling combines with the open floorplan to create a very livable, natural, healthy atmosphere.

  • Indoor planterbeds get direct almost 90 degree penetration sunlight through angled glass at winter solstice. This ensures maximum solar heat gain and natural light when they are needed most right in the middle of a cold, dark winter. Sloped glazing may have an unconventional look about it, but it is the only way to sustainably grow crops AND heat a home. With a well-chosen building site, the glass can be hidden on the backside of the home in urban areas to mimic the look of a conventional house from the street. If you live in a hot climate, the need for sloped glass is likely not an issue and you can go with vertical glass to save money and present a more conventional look.

  • Hanging plants are one option for room division and privacy. Drapes, sheers, shade cloth, water filled columns, glass block walls, and moveable partitions are some other answers besides building walls to box-in the rooms. Please note that interior doors and walls are easily added later, after you have had a chance to live in the home for a while and experience the difference that an HTM makes. Don't judge the open layout based upon living in conventional homes for your whole life. Clients are encouraged to live a floorplan for a while to get the feel of an HTM before building additional partition walls. The difference a drape 'wall' or movable partition can make is dramatic, without the permanence of a wall.

  • HTMs provide endless possibilities for personalization of interior design. There are no limits to the variations, be it rustic with salvaged materials like you see here or something more modern. In general, the interior wall and floor coverings have very little overall affect on passive solar performance, as long as the wall core is concrete or similar high thermal mass building material.

  • The key to passive solar function is keeping the floorplan as open as possible, but everybody has their own personal concept of their dream home, so alterations are made to the basic layout with understanding that every aesthetic change has a related functional effect. You take what free solar gain there is available in your area and supplement the rest, just like any other home. Form follows Function, with holistic design being critical in more sustainable zero-energy passive solar structures.

  • Passive Solar textbooks all seem to present a rather confusing 'shotgun effect' with a laundry list of options,
    all based upon conventional residential stick-frame architectural models... but some do think outside the box.

    Free 48 State Delivery

    All shopping cart items are advertised as Free Shipping with no extra charge for delivery. Shipping and handling fees are factored into advertised total delivered price. Note shipping is only available to the 48 contiguous United States of America. We do not ship into Canada or Mexico, Puerto Rico, Alaska, Hawaii, Virgin Isles, APO/FPO mailboxes, or any off-shore or international destination. Inventory 'stock' items will ship within 2-3 business days from one of Our warehouses. Scheduled deliveries are not possible to arrange, but We automatically email tracking information after shipment, so you can anticipate delivery date. Motor freight deliveries do not include lift gate service to lower boxes onto the roadway, unless quoted with additional services. If need be, lift gate service to lower boxes onto roadway is available for an additional $65 to $100 fee. Street-side motor freight deliveries are not brought to your front door by the driver, like UPS and Fed-Ex package services. Client must meet motor freight truck deliveries on the street to unload and inspect shipments by hand before signing for Merchandise. Shipments must be accepted promptly within three days of arrival at local freight terminal or storage fees of +/- $50 per day, per pallet may apply. Any and all storage fees billed by trucking company are the sole responsibility of Client and must be reimbursed to Our company.

    Fed-Ex and UPS Ground

    Most shopping cart items ship via Fed-Ex or UPS Ground package delivery service. Package delivery services, unlike a motor freight carrier (see next paragraph), will allow us to file a hidden damage in transit claim for insurance reimbursement, but We are given less than a week to report it. Regardless of how well the exterior of container box appears, you must ALWAYS have the driver note ANY damage to shipping boxes in writing before signing. Then immediately, always take Merchandise completely out of its packaging and inspect ALL of the Merchandise, notifying us immediately should there be ANY hidden damage to Merchandise. Mechanical problems are covered under the manufacturer warranty, but hidden aesthetic damages (cosmetic dings, dents, broken Welds, significant scratches, or popped rivets) you discover than a week after delivery are not reimbursed or replaced by Fed-EX, manufacturer, Kobe, or Not saying that you or your Merchant caused the damage to the unit before or during installation, but that possibility exists when Merchandise is not properly inspected upon arrival. Additionally, any appearance (non-mechanical) flaws found after installation will not be reimbursed or replaced by freight carrier, Fed-EX, manufacturer, Kobe, or Merchandise that has been installed is not eligible for return or replacement by

    Motor Freight Shipping

    Servel refrigerators, Sun-Mar composters, larger custom shade panels and larger Kobe range hoods ship via motor freight 'common carrier', as noted on the website and receipt. Scheduled deliveries are not possible to arrange, but We automatically email tracking information after shipment, so you can anticipate delivery date.Common carrier motor freight is shipped on a pallet with boxes covered in clear plastic stretch-wrap and is defined as street-side motor freight drop, which differs from small package services like UPS and Fed-Ex, in that the truck driver does not bring Merchandise into your building or onto the porch. Street-side motor freight drop is a basic delivery service, often in a full-size tractor trailer, where driver parks in street while you unload and inspect the Merchandise. Kobe range hoods, shade panels, and Sun-Mar composters are not shipped with lift-gate service. You must unload boxes from the tractor trailer by hand. If you require lift gate service to lower the Kobe range hood down onto the roadway, with what they call a mechanical 'Tommy lift', it is available for an additional $65 to $100 fee. Please arrange and pay for this optional service at time of order. Always check the number of pieces (boxes) present against the stated waybill shipping receipt tally. As with any motor freight shipment from any distributor, be certain to carefully examine ALL of the Merchandise, not just the outside of shipping box(es), before signing and accepting delivery. It is imperative with motor freight shipments that ALL products be unboxed and fully inspected PRIOR to accepting delivery. Regardless of what the delivery driver may say, you MUST inspect fully before signing and accepting the delivery. It is the freight truck driver's job to wait while you open and inspect shipment for damages. Simply looking at the outside of the box(es) is NOT adequate. Damaged Merchandise (that particular box, not all the boxes) must be refused delivery. Once someone signs for shipment, it confirms Merchandise was received free of ANY damage and removes liability from the transportation carrier. We can only assume that damage reported later and not refused delivery, was caused by the Client, and not the freight carrier. Any subsequent attempt to file a claim for loss or damage will NOT be accepted by the transportation carrier, distributor, or Our company,

    Returns and Cancellation

    All returns, cancellations and/or exchanges must first be authorized in writing by at Client may not ship any Merchandise back until We supply return Merchandise authorization RMA number and address for the shipment. Orders often do not ship back to the same warehouse they shipped from originally. Contact us with invoice number and reason for return or exchange to obtain an RMA number and instructions. No returns, refunds or exchanges will be authorized more than 30 days after original purchase payment date. Design consultation services, DVDs, knit shade material, water tubes, greywater and septic system parts are not returnable for refund or exchange for any reason. Once payment has been made, custom panel orders are cut and enter the production system and cannot be cancelled after payment is made. No return on any remnants or discontinued items. Any authorized returns of Merchandise must be in the original carton, in new unused condition, and returned freight prepaid to Our designated warehouse. Merchandise originally shipped via motor freight carrier on a pallet, may not be returned via package delivery service such as UPS or Fed-Ex. Original actual shipping cost will be deducted from any refund due along with up to 15% restocking fee on the Merchandise. This restocking fee includes the 3% credit card processing on original purchase, which is not refunded by MasterCard or VISA. Please understand that items on Our website are advertised as "Free Shipping", which is to be understood as "there is no extra charge for delivery of PURCHASED Merchandise". UPS, USPS, Fed-Ex and motor freight carriers charge us a fee for delivery of Merchandise, which We must recoup on returns. Kobe, for instance, bills a flat-fee of $40 and $45 for business and residential Fed-Ex shipments and $162 and $186 for motor freight carrier drops. Sun-Mar and Servel units ship via motor freight carrier for anywhere from $120 to $300+ per unit, depending upon zip code and drop site designation. Kobe, Sun-Mar, Clivus Multrum, Quanics, Dometic and Servel returns are manufacturer-direct, drop ship items and may be subject to an additional manufacturer's restocking fee. Discontinued, clearance items are not eligible for return or exchange. If an item is returned without original packaging intact, or is damaged, found to be used, or otherwise not ready for resale, it may be refused and returned to sender at their expense, so always insure shipment.

    Lost and Stolen Shipments

    Tracking information is emailed following shipment on all orders so client can anticipate delivery date. Custom size shade panels are made-to-order and can take up to ten business days to produce and ship. All other 'stock items' normally ship within three business days. Should you not receive email shipping information, please send a request for tracking number in writing to: Note it can take up to 48 hours for a given tracking number to appear on transportation company website. During this time, shipment status may be listed as "order processed and ready for pickup". Traditionally, this just means the shipment has not yet reached transportation company terminal and scanned after being unloaded from truck that picked those package(s) up. Overdue shipments must be reported to merchant in writing within one week after anticipated delivery date. Cardholder hereby agrees that only two possibilities exist for a shipment that did not arrive as anticipated. Possibility #1) Transportation company shows shipment as still being in-transit. In this case, merchant will file a 'tracer' request on behalf of cardholder with transportation company and they will search for box(es) at all company freight terminals. Cardholder is required to fully cooperate by filling out any forms requested, returning any voice messages left, and replying to any email messages sent by transportation company or merchant. Your patience and consideration is required and greatly appreciated while transportation company attempts to find the shipment. Replacement or refund is authorized solely at merchant discretion. Cardholder is not permitted to cancel order. Cardholder is not permitted to dictate choice of replacement or refund. And cardholder is not permitted to dictate time frame for settlement and ultimate delivery date for merchandise. Possibility #2) Transportation company shows shipment as being delivered. In this case, merchant will file a 'lost shipment' claim on behalf of cardholder with transportation company. A lost shipment claim can take up to two weeks to resolve and unfortunately, the transportation company rarely, if ever, pays the insurance claim. Ideally, we only ship to cardholder, personally, at their residence or business 'home' credit card billing address, but regardless of designated drop site and receiving person and whether or not a signature was required at time of delivery, cardholder is solely responsible for merchandise security after drop is confirmed by transportation company. After transportation company confirms delivery to shipping address, no signature required, there will be no refund or replacement for lost or stolen merchandise for any reason. Cardholder must immediately file a theft report with their local police department for item stolen from property or designated drop site. Cardholder hereby agrees to relinquish any and all right to file a credit card chargeback sales reversal for merchandise lost in transit by transportation company or merchandise reported lost or stolen after delivery is confirmed by transportation company. Should cardholder file a chargeback in violation of this terms of service agreement, cardholder will be held responsible for reimbursement of any and all merchant services processing fees incurred as a result of the frivolous chargeback, which can be anywhere from $35 up to several hundred dollars.

    Shade Panel Production

    Our commercial grade knitted shadecloth carries a one year manufacturer's replacement warranty against defects in material and workmanship. You can expect at least 5 years of service when installed properly and well over ten years when used seasonally in a temperate climate. Client must inspect shade panels within one week of delivery in order to be able to report any damages. Rips, tears, and aesthetic damage you find more than one week after delivery are not reimbursed or replaced by the freight carrier or Additionally, merchandise that has been installed is not eligible for return or replacement for damage claims. Fabric is knitted polyolefin, primarily high density polyethylene HDPE, specially treated for durability and UV resistance. Wind damage from loose panel whipping, snagging, and abrading against the structure or cable framework is much more harmful in the long run than simple exposure to sunlight. Knit shade material should be installed hung underneath, not pulled across the top of cable or framework, to avoid abrasion and snagging damage. Chemical, fire, heat, abrasion, and snagging damage are not covered under manufacturer warranty. Shade panel warranty inspection returns must be authorized in advance and returned freight prepaid to designated location for visual inspection. will only pay the cost to ship warranty repaired or replaced merchandise back to client after inspection confirms damage was a material or workmanship defect. The following are trade-standard, non-valid reasons for requesting warranty inspection: First, there is no up-down, right-left, top-bottom or front-back reference point for any panel. Panel 'Width and Length' are measured from outside-edge to outside-edge of the sewn perimeter hem at the four corners only. Knit material has inherent tension and flex in the looming process that will resolve aesthetic issues when installed taut with rope lacing. Grommets on one side of panel are unlikely to line up with grommets on the opposite side or from one grommeted pinch pleat to the next. Exact one foot on-center grommet spacing, specific grommeted pinch pleat centering, and special placement on a particular side for grommets is not warranted. Any panel over 12 foot wide may have a noticeable factory knitted loom splice seam without notice in advance since the 20, 26, and 32 foot wide stock roll width fabrics are manufactured on side-by-side looms. We traditionally cover this seam with a grommeted pinch pleat, but it is possible to order plain cloth without a center GPP, per automated quoting form. Aesthetic issues are not warranted. For instance, the White 50% color knitted shade material can sometimes arrive with patches of orange discoloration and spotting as a result of the manufacturing process. This discoloration will dissipate after installation in the sunlight. Shade material may always be slightly wrinkled from rolling onto storage tube or shipping and knit appearance can vary from sample swatches presented and may also vary between various stock widths. Minor aesthetic flaws in knit appearance, stitching, and snags are not a structural panel failure problem and not warranted. Shade material is lockstitch knitted to prevent structural unraveling. Longevity is the same regardless of aesthetic appearance flaws in the fabric knit or perimeter webbing. If need be, one can use needle and thread to pull small flaws together and super-glue sealed. It is not considered a warranty-related defect unless it affects panel performance. Special fire resistant certified shade materials are not available. The finish 'Length' ordered is what we produce by cutting enough fabric to fold hem and GPP. The only time to anticipate deviation in finish dimension purchased is when 'Width' is a stock material width of 6, 8, 10, 12, 20, 26 and 32 foot. Then, finish 'Width' is likely going to be two to three inches less after folding and sewing perimeter hem and any length-wise grommeted pinch pleats. ALL other times, the size panel you request is the finish size we do our very best to produce. Knitted shade netting is inherently difficult to work with due to tension releasing when cut to custom sizes, so trade-standard warranty for free replacement is a four inch tolerance. As measured at four corners, any error of five inches, or more, is warranted for free remake, replacement, or refund at our sole discretion. This accuracy guarantee does not apply to shapes other than rectangles or any panel dimension over 32 foot. Errors of less than five inches are considered for remedy on a case-by-case basis only when the panel has not been installed and can be resold as a new-unused remnant. Special grommet placement requests are not warranted and grommet spacing at exactly one foot on center is not warranted.
