The SWS block; Results in a savings of the cost of mortar (since none is used in the SWS block). Lower wage, unskilled laborers instead (high-cost, skilled masons are not needed for block plumb and mortar). SWS block is larger (twice the width and height & three times the length) resulting in less trips to carry block and less time to stack it. SWS blocks are light weight at 34 pounds (reducing lost hours and medical costs by lowering the rate of back injury, hand & finger injury and foot injury). Slide 3: Cement block commonly used in the USA and Mexico have virtually no insulation values coming in at a measured R3 factor –VS- SWS block which has a R47 insulating factor. The SWS block; Saves on heating and cooling, without any additional insulation applied and in moderate climates such as Aguascalientes, additional heat & cooling will not often be necessary. In northern climates, heating and cooling may be reduced as much as 80% over raw conventional block. Buildings built from SWS block, lower the load on the electric utility companies, which results in; Lower utility bills. Lowers pollution from fuel based electric production, resulting in lower carbon being released into atmosphere. Lengthens the cost of maintenance and machinery upgrades at electrical facilities by reducing the load. Promotes lower cost solar and alternative fuels. High insulation reduces the size of the PV panels required to furnish power for heating and cooling, which in turn lowers the cost of solar larger solar panels. Since the high insulation factor is due to the polystyrene pellets, and with the porous cement and poly surface, the combination creates an extremely quiet environment , which; Deadens loud noise from traffic from nearby street, highway and rail traffic. When used as housing sub-division sound barrier walls, the environment is more accommodating to even luxury homes creating a higher value for land sellers near noise sources. If used for interior dividing walls, disturbing noises such as loud TV, children playing, and the usual small annoyances become a thing of the past. Slide 4: Manufacturing plants are designed to be in an open air environment on a cement slab with a “roof-over” at a 30 foot clearance, so a building with walls is not necessary in moderate climates. Of course, the plant is completely functional inside any building as well and with the newer, more efficient designs, the plants remain relatively clean. Slide 5: Environmentally, SWS is less invasive to the planet, uses far less fossil fuels, promotes recycling and reduces over-filling of landfills. Cement block requires sand and gravel, which must be excavated from the earth and often results in dangerous craters that remain long after the area has been abandoned. Cement is still a component of SWS block but represents less than 15% of each finished block. 92% of each block is made of recycled, ground polystyrene pellets. In most cases polystyrene block that is used to ship materials and components to Mexico’s burgeoning assembly plants, is unwanted and hauled to landfills where it will remain for hundreds of years. Currently, Mexico faces unmatched overfilling of landfills with some estimates of the Polystyrene percentage at well over 60% in manufacturing communities. An entire polystyrene recycling industry can now be created by arranging for and transporting Poly from local companies and pelletizing the poly. New jobs can be created by transporting, sorting, stacking, pelletizing, filling storage bags (containers) and administrative duties. Opportunities for small check stations at landfills which could be manned to remove polystyrene prior to dumping. The lower cost of the SWS block could be a revenue source. The manufacturing plants would purchase the pelletized Poly, which would pay for the landfill station attendant and transports. Slide 6: Concrete Mix (Ready Mix) trucks consume an immense amount of mostly diesel (and a percentage powered by gasoline) deliver concrete to building projects all over Mexico to be poured through the center holes in conventional cement blocks to hold the “rebar” infrastructure in place and stabilize the walls. –VS- SWS block which uses “70%” LESS CONCRETE POUR to stabilize its rebar and wall infrastructure. Again, building costs are reduced tremendously on the over-all construction project due to using 70% less concrete fill requirements. The direct result is less fossil fuel costs and usage due to fewer trips to building sites for Ready Mix concrete delivery and pumping. Lower fuel usage reduces pollutants from truck emissions which can then be directly attributed to building contractors and the reduction in concrete supply and volume requirements. Slide 7: There is also an ecological savings by reducing the water needed for the Block production. The SWS Block uses .66% “LESS” water in making SWS Block over CMU Block. Slide 8: Conventional cement block may be mortared and stacked to a maximum common height of approximately 4 to 5 foot tall sections. This is due to the “floating” of the cement block during the concrete fill process from the Ready Mix truck pumps. Once the first level is filled, the skilled mason can begin mortaring and stacking of the next 4 foot level (or lift) and the Concrete Truck must return and fill the that layer. This process continues again and again. If the level is built too tall, the cement blocks will often have “holes” or empty spots whereby the concrete did not properly fill to that depth. –VS- SWS block may easily be “dry-stacked” to a height of one story (1 floor) and add the concrete fill only once per “story or floor”. The result is again, less trips made by the truck, less fossil fuel used, less man hours for the concrete delivery company and less wasted man hours paid by the contractor, due to time waste in re-delivery coordination and idle or worker job position shifts while concrete is poured. The realized savings to the construction industry has a very wide reach and therefore requires long term study to calculate exactly what the full extent of the actual savings can be. This is certainly far more than a block to block price comparison. Slide 9: Two last issues that I believe may be among the most important are the incredible time savings in erecting an SWS WALL SYSTEM building and the incredible ease with which any unskilled laborer is able to learn the system and begin building. The time savings is immense once the system is understood and the contractor learns to work with the materials, and the architects learn the design specifications and material differences. This can quickly bring homes and commercial buildings to a much shorter ground to move-in condition. In my estimation, this could shorten contractor loan timeframes and possibly some savings on bank interest. It would also turn raw materials into market ready sales in shorter timeframes in which the net result is keeping the cash flowing throughout the financial infrastructure of Mexico, which will only help maintain a healthy economy. With such an relatively lightweight and easy to understand building material, more workers can be trained and will result in the introduction of additional unskilled laborers into the work force and skilled laborers will become supervisors making more per hour, since one skilled mason can supervise the entire SWS WALL SYSTEM process for an entire structure. It is likely that with good contractor coordination, each contractor could build more projects at the same time. “As a matter of humanity and bettering the human condition in so many parts of our world, I can quickly envision a program that will empower the low income and displaced citizens to learn the process of setting the foundation and stacking their own block to create rudimentary, but simple structures that will shelter themselves and their families from the elements. Perhaps this is just a dream, but this is a dream that I like to keep in my heart.” Slide 10: LIMITATIONS OF PRODUCT: SWS WALL SYSTEM Block is well studied and has excellent stress tolerances for walls. It is not however as hard as conventional cement block, and therefore must be used for its intended purpose in walls. It is not the proper material for structural columns and supports. Slide 11: ADDITIONAL INFORMATION: An SWS WALL SYSTEM manufacturing plant is capable of operation by “utility grid” electric connections or by generators. The $1.5 million USD plant manufactures a minimum of 500 finished SWS blocks per shift and includes the full generator power source package. SWS WALL SYSTEM PLANTS ARE AVAILABLE IN A MOBILE SET-UP. This includes a reduced daily production and limited storage for BLOCK MOULDS and POLYSTYRENE/CEMENT MIX, which would require other transport. The plant would be efficiently mounted on a powerful flat bed Semi-Truck and Trailer. The additional cost is approximately $100,000 to $200,000 USD based on plant capacities and truck options. This could be very useful in new developments, rural industrial building projects, and urban areas within an estimated radius of 500 miles or more. SWS Block is lightweight and easy to handle and transport. However, I have not done any studies on the savings in fuel, if any from the lighter load when compared with conventional concrete block shipping weights.
