Some embodiments are related generally to energy efficient construction, such as to a thermal wall technology and construction and assembly method that incorporates hydronic tubing in the thermal mass of the wall through the use of an improved type of interlocking mortarless structural concrete block form, a per-bent polymer water tubing system or air tube system is positioned inside the center of the block, typically the full length of the wall, then concrete or other thermally conducting material is poured into the interspatial connecting cavities of the block to create a monolithic pour. Afterwards insulation and an exterior attachment system is applied.
Buildings are constructed from a variety materials and methods. The primary types of construction are wood frame, insulated concrete forms and concrete block.
Wood frame construction typically utilizes 2×4 inch or 2×6 inch lumber to construct a frame. The frame is then reinforced with sheathing materials attached to the exterior and/or interior of the structure. Various types of insulation are inserted between the interior and exterior sheathing. This type of construction has numerous drawbacks; low strength, higher maintenance, shorter building longevity, flammable, low thermal mass, insect damage susceptibility, higher air infiltration, higher allergy concerns and higher heating and cooling costs.
An emerging method of construction is insulated concrete forms (ICFs) which is currently about 10% of the U.S. market. ICFs are comprised of two (typically rectangle) rigid insulation panels separated by a polymer matrix. The two rectangle insulation forms are designed to be stackable with interlocking edges (top, bottom and sides). The cavity between the insulated panels (which is typically between 4 and 8 inches) is filled with concrete forming an insulated concrete wall. Such form systems have limitations on the wall height, as such concrete is then placed in the form and allowed to harden sufficiently before another course of insulating forms are added on top of the existing forms. Such systems result in cold joints between the various concrete layers necessary to form floor-to-ceiling walls or a multi-story building. Cold joints in a concrete wall weaken the wall therefore requiring that the wall be thicker and/or use higher strength concrete than would otherwise be necessary with a wall that did not have cold joints.
ICF technology, however overcomes some of the drawbacks of wood frame construction by providing good strength, less flammable, less infiltration and better allergy concern and reduced heating and cooling costs compared to wood frame and concrete block construction. The drawbacks to ICF construction are high cost of construction and insulation on the interior is susceptible to fire and outgas sing of the insulation can lead to health concerns. Drawbacks aside, ICF construction is considered superior to wood frame construction.
Concrete blocks also known as concrete masonry units (CMU) have been a U.S. staple building material since the early 1900's. CMUs are manufactured regionally throughout the U.S. and provide a low-cost, strong, fire-resistant construction option. CMU blocks come in a variety of dimensions with the standard block being 15-⅝×7-⅝×7-⅝ inches in diameter and typically having one or two cross members (not counting the ends), extending from the top to the bottom in the interior of the block to provide additional strength. CMUs are structural units capable of supporting the building infrastructure, however rebar is required by code in many local jurisdictions. The primary drawbacks of CMUs are cracking along mortar joints and poor insulating features resulting in high heating and cooling cost.
Traditional CMUs are glued together using mortar. The bed and head joints do little for structural integrity, merely adding a heavy mass of mortar to glue the separate blocks together. The results are a substantial amount of non-functioning mass versus overall intended functionality, or structural deficiency. Walls of this type have a tendency to fail exactly on joint lines. Mortared joints do little for overall structural integrity.
Traditional CMUs (being a load-bearing product) have a crossmember feature from top to bottom across the middle of the block. This crossmember results in the creation of individual vertical cells within the wall. To reinforce the wall rebar is inserted in some cells and filled with concrete. This crossmember extending from the top to the bottom of the block however prohibits the diagonal/horizontal flow of concrete to adjacent cells which substantially limits the wall strength when compared to ICFs. Core-filling is not a design function of traditional concrete blocks.
Traditional blocks are designed to be both load-bearing and as lightweight as possible. This lightweight feature (a result of air entrainment in the concrete block) acts as a thermal insulator, interfering with the thermal conductance of the block. This is not a negative feature for CMU construction but is incompatible with the improved technology.
All conventional forms of construction rely heavily on the use of thermal insulation. ICF construction has some thermal mass features, however with the thermal mass isolated by the insulation its benefits are principally negated. Thermal insulation has limitations as it has diminishing returns as R-value increases. In the U.S. around the year 1950, 3.5 inches of fiberglass insulation (R13, or approximately 9 Btu heat loss per square foot) became the standard to reduce heat loss. In the early 2000's the standard shifted to 6 inches of fiberglass insulation (R19, or approximately 6 Btu heat loss per square foot) to further reduce heat loss. Note the nearly doubling of insulation only provided an approximate 30% reduction in heat loss; this is because thermal insulation has limitations as it has diminishing returns with increased thickness/R-value). To achieve an additional 3 Btu per square foot heat reduction would require an R-value of over 40 or well over a foot of insulation. Note for many people in poverty the homes built in the 1950's with 3.5 inches of insulation are now uninhabitable due to the high cost of heating. As energy demands increase with predicted population growth the homes built today in 50-years will very likely also be uninhabitable and insulation, due to its diminishing returns cannot again provide a temporary solution. The purpose of this discussion is to illustrate the limitations of conventional building technologies and to introduce alternative construction components and an improved building method.
The present invention is now exemplified by a particular embodiment which is illustrated in the accompanying drawings. In particular, the present invention discloses a construction system for the walls of a building. For purposes herein, reference to “walls” or “wall” shall mean the side, back and front walls, and floor of a structure.
According to one embodiment, a thermal wall system may include a plurality of blocks configured to interconnect with each other forming a monolithic wall when filled with concrete or other thermally conductive materials. The plurality of blocks form a series of vertical, interior cavities that each extend from a top of the plurality of blocks to a bottom of the plurality of blocks, and tubing vertically extends through the series of vertical interior cavities.
According to one embodiment, a thermal wall system may include a plurality of blocks configured to interconnect with each other forming a monolithic wall when filled with concrete or other thermally conductive materials. The blocks having the ends reduced in height and the center crossmember further reduced in height so as to form interspatial connecting cavities and interspatial communication between the cells of a block and between the blocks.
According to one embodiment, a method may include: forming a monolithic wall by connecting a plurality of blocks with each other each having interspatial connected cavities, the plurality of blocks forming a series of vertical hollow interior cavities; inserting tubing vertically into the series of vertical hollow interior cavities so that the tubing extends from a top portion of the wall vertically down to a bottom portion of the wall; attaching insulation to an exterior surface of the blocks so as to reflect thermal energy towards an opposing side of the blocks; and after the inserting the tubing and attaching the insulation, filling the vertical hollow interior cavities with a material thereby allowing the material to flow from a first block to other blocks in a direction perpendicular to the vertically-extending portions of the tubing.
According to one embodiment, a system may include a plurality of blocks configured to interconnect with each other forming a monolithic wall, the plurality of blocks forming a series of vertical interior cavities that each extend from a top of the plurality of blocks to a bottom of the plurality of blocks, the vertical interior cavities configured to receive tubing to vertically extend through the series of vertical interior cavities. Each of the plurality of blocks may include a notch configured to receive an alignment grommet and a pair of ridges configured to receive a portion of the grommet when the grommet is installed in a notch of another block. The system may also include an insulation board that is configured to be attached to the grommet, an exterior surface of the blocks.
Aspects of the present invention is further described in the detailed description which follows in reference to the noted plurality of drawings by way of non-limiting examples of embodiments of the present invention in which like reference numerals represent similar parts throughout the several views of the drawings and wherein:
Below is a general overcome of some embodiments.
For example, some embodiments provides an improved construction method utilizing interlocking block forms, thermal mass construction, interlocking insulation systems enhancing daily natural heating and cooling cycles and enhancing renewable resources. Some of the methods described herein achieve an ultra-efficient home and building construction system allowing the shell of the home (walls and floors) to act as both a heating and cooling storage system and a heating and cooling delivery system. As a result of the building system described herein, embodiments of the present invention through improved thermodynamics and lower operating temperatures enhances the efficiency of traditional heating and cooling systems between 39 and 60%, hydronic solar collectors by 69% passive solar efficiency by 50-75% and almost eliminates space cooling requirements. Additionally, conventional hydronic solar collectors have only provided hot water and space heat, however this technology can also provide space cooling, to provide both solar heating and cooling. Embodiments of the present invention, due to the building system and method, operate at much reduced operating temperature, this lower operating temperature results in numerous thermal efficiencies. Industrial hot or warm water discharges are common throughout the world. This heated water has no beneficial use and in fact causes negative environmental impacts and/or costs billions of dollars to manage. Embodiments of the present invention have the physical characteristic to be able to utilize this industrial warm water to heat buildings. Embodiments of the present invention utilize accessible thermal mass to ameliorate the temperature in the summer. The thermal mass assumes the average 24-hour temperature instead of the daily extremes exhibited by low mass structures such as wood frame construction. As such the present invention virtually eliminates the need for space cooling. Embodiments of the present invention also provides a structure that exceeds hurricane standards, reduces infiltration, reduces air infiltration, reduces pollutants which cause allergies, is economically competitive with conventional technology, almost eliminates heating and cooling requirements, enhances efficiency for solar renewable resources, can utilize industrial warm water discharges reducing energy and the carbon and air emissions and sets a template and trajectory toward human sustainable shelter.

Each embodiment described herein is not necessarily intended to address every object described herein, and each embodiment does not necessarily include each feature described. Other forms, embodiments, objects, advantages, benefits, features, and aspects of the present invention will become apparent to one of skill in the art from the detailed description and drawings contained herein. Moreover, the various apparatuses and methods described in this summary section, as well as elsewhere in this application, can be expressed as a large number of different combinations and subcombinations. All such useful, novel, and inventive combinations and subcombinations are contemplated herein, it being recognized that the explicit expression of each of these combinations is unnecessary.
Embodiments of the present invention relates to an energy efficient construction system that in one embodiment, is an insulated concrete block (ICB) form which has unique characteristics of creating interspatial communication between cells of blocks and between blocks, enabling horizontal and diagonal flow of concrete between cells to provide enhance strength and thermal communication, an alignment feature which enables simplified and correct construction methods also providing the ability to dry stack the ICB s, a denser concrete composition to enable critical thermal heat transfer, thinner side walls to provide for lighter ICB, an attachment system for exterior insulation.
An additional embodiment is the inclusion of an alignment grommet which attaches into a notch on the side of the ICB which enables block alignment for quick and accurate construction. It is constructed to accept and receive a pin that locks in place inside the grommet and acts as a support system for the rigid insulation board.
An additional embodiment is an insulation support pin. This pinning system device locks into the grommet and acts as a support and attachment system for the rigid insulation board, which has a second pinning/attachment system on the distal end from the grommet which locks into an insulation retaining channel which holds the ridged insulation board in place.
An addition embodiment is an insulation retaining channel configuration which allows the support pin to snap on flush with the insulation, holding the rigid insulation board in place, while providing an attachment medium for all forms of exterior facades.
An additional embodiment is a rigid insulation board with perforated holes in the same configuration as the ICB grommet matrix whereas insulation support pins are easily inserted into the perforated holes within the grooves on the exterior of the rigid insulation board to accept the insulation retaining channel and be flush with the surface of the rigid insulation board.
An additional embodiment is a pre-bent polymer water tube or air tube in such a configuration so as to be able to be inserted vertically into the cavities of the ICBs so as to provide the walls with thermal heat or cooling. In some embodiments, the material flowing through the tubing can be any material, such as water, air, etc.
An additional embodiment is a tube spacing and guide device configured to snap on the pre-bent polymer water tube or air tube in order to maintain the tubing at a uniform distance apart from each other and to provide a guide system to maintain the tubing at desired distance from the inner cell walls when inserted into the ICBs.
The ICBs are dry stacked after the alignment grommets are installed in the notch in the ICB. Following completion of the ICB wall, the insulation support pins are inserted and locked into the alignment grommets. The rigid insulation board with the perforated holes in the same configuration as the insulation support pins is inserted over the insulation support pins. The insulation retaining channel is then snapped and locked on the exterior end of the insulation support pin locking the insulation in place. The pre-bent polymer water tubing with the tube spacing and tube guide device is lowered into the cells of the ICBs and connected to a water heating/cooling source to affect the temperature of the building. Concrete is then poured into the cells of the ICBs to provide the thermal mass thus effectuating the thermal efficiencies. The chosen exterior façade is then attached to the insulation retaining channel.
As will be seen from the subsequent description, the preferred embodiments of the present invention and method overcome disadvantages of the prior art. In this regard, the present invention discloses a system allowing the walls and floors to provide both traditional heating and cooling and greatly enhance solar heating and cooling in a building that can be controlled evenly, efficiently, with greater flexibly at a lower cost.
