Description
- This application claims the benefit of U.S. Provisional Patent Application No. 61/070,992, filed on Mar. 27, 2008.
- This invention is generally related to a novel cabin design and centralized renewable energy recirculation/recovery system.
- Conventional heat recovery systems typically involve gas fired forced air and/or boiler heat sink technology. The present invention improves on these conventional heat recovery systems by providing an integrated air flow induction system that continually recirculates ambient and passive solar air through a combination of hollow-core wall and floor beam sections via a centrally located wood burning open hearth fireplace insert to heat the structure.
- The present invention is also a departure from the conventional use of panelized wall sections used in the building industry today. While the panelized wall is a relatively common wall system in most climatic conditions, it is susceptible to damage in instances of high winds and/or water-laden weather conditions. This invention offers an “architecturally green” alternative to the traditional panelized system while at the same time incorporating “high impact resistant” design features to the overall structure characteristic of solid timber construction in thwarting hurricane type airborne debris damage.
- Consistent with the author's long standing appreciation for timber framing technology coupled with a desire to provide the occupant(s) with “campfire under a roof” atmosphere, the archetypical cabin design emerged.
- An objective of the present invention is to provide an improved living space heat recovery system within a novel cabin design scheme. The invention has three primary components.
- First, the invention, in a preferred embodiment, may employ an innovative low profile, polyhedron canopy roof design rising up from a modified octagonal floor plan comprising the main cabin design envelope. A combination of fixed and articulating triangular skylights allow for passive solar heating during the winter months and open air ventilation and cooling in the summer.
- Second, the invention includes a centrally located 360 degree open hearth heating system.
- Third, the invention provides an air induction and heat recovery system that recycles ambient air through ventilated or hollow core wall and floor beam sections, and then via induction back through a dampening air plenum under the hearth fire box insert to redistribute return air into the living space.

- With reference now to
FIGS. 1A and 1B , building elevation plans of one embodiment of the present disclosure are shown.FIG. 1A shows an aerial view of abuilding structure 10 having a central,open hearth system 100 designed to receive returned air from thebuilding 10, re-heat the returned air and circulate the re-heated returned air back through thebuilding 10. The embodiment ofFIG. 1A further shows anoctagonal building structure 10 including adeck 12 surrounding the perimeter of thestructure 10. Each of the eightjoints 14 of theoctagonal structure 10 is configured to secure two of thewall panel systems 16 together, thereby supporting thestructure 10. Furthermore, at the base, or floor, of eachjoint 14 is a hollow corefloor beam system 18 extending inwardly from itscorresponding joint 14 toward the centrally locatedopen hearth assembly 100. - The arrows of
FIG. 2C illustrate the flow of air through thebuilding 10. The heated air flows from thehearth system 100, propelled via avariable speed fan 106, disposed within thehearth system 100, through thebuilding 10 and returns through thehollow wall panels 42 andhollow floor beams 46 of thestructure 10. The returned air eventually reaches theplenum 102 of thehearth system 10, thereby allowing the air to be re-heated and re-circulated by thefan 106. The operation of thehearth assembly 100 as well as the heat recovery system will be described in more detail below. -
FIG. 1B shows elevation plans of one embodiment of thebuilding structure 10 ofFIG. 1A wherein illustration (i) shows a front elevation plan, illustration (ii) shows a side elevation plan, and illustration (iii) shows a rear elevation plan. Illustration (i) shows thebuilding structure 10 including anmetal fascia roof 20 supported byroof framing supports 22. In this embodiment, theroof 20 is a low profile, polyhedron canopy roof. Theroof 20 may also be downward sloping, as shown, as can be insulated. - The
windows 24 shown in illustration (i) and (ii) are exemplary, and the placement and shape ofsuch windows 24 may be configured in accordance with one's preferences. Thesolid wood columns 26 shown correspond to the joint locations between thewall panels 28. Each of thesolid wood columns 26 is secured to a reinforcedconcrete pier 30 to stabilize and anchor thebuilding 10 in case of inclement weather. Similarly, the centrally locatedhearth system 100 is supported by aconcrete 32. Thisfooter 32 can be a pre-cast concrete faulted footer. - Illustration (ii) of

roof 20 andbuilding 10 may be supported bysolid wood columns 26 incorporated into the perimeter of thebuilding 10. For example, in the octagonal structure shown inFIG. 1A , eightsolid wood columns 26 would support theroof 20 and building 10, one of the eight solid onecolumns 26 being disposed at each of the eightjoints 14 which join thepanels 16, thereby forming theoctagonal structure 10. - In exemplary embodiments of the
building structure 10 shown in illustrations (i)-(iii), thechimney 38 may be astone chimney 38. Theroof 20 may be a standing seam metal roof and adeck 12 surrounding the perimeter of the structure may also be included. Furthermore, thestructure 10 may be supported by reinforcedconcrete piers 30, or other similar support mechanisms. - With reference now to
FIGS. 2A-2D ,FIG. 2A shows an enlarged, detailed view of one of thejoints 40 in the octagonal building structure ofFIGS. 1A and 1B , at the base of one of thesolid wood columns 42. As mentioned, thesolid wood columns 42 join two of the hollow corewall panel units 44 at each of thejoint locations 40. Eachsolid wood column 42 is also joined to a hollowcore floor beam 46 at the base, or floor, of the structure. Asteel knife plate 48 may be configured to secure thewood columns 42 to the floor beams 46.Slots 50 in thewood columns 42 are configured to engage thewall panels 44, securing them therein, as shown inFIG. 2A .Wood columns 42 are laminated in one embodiment of the invention. Floor support beams 52 are positioned at the base of thestructure 10, throughout thestructure 10, to reinforce and stabilize the floor of thestructure 10. These support beams 52 are connected at one end to one of the hollow core floor beams 46 and an a second end to another hollowcore floor beam 46, providing a frame-like structure upon which sheathing (preferably insulated) and wood flooring, or similar flooring used in the art, may be installed. Furthermore, an additional sheathing is disposed below the frame-like structure mentioned above. This external sheathing may be made from exterior-grade plywood or other suitable material. The space defined between the support beams 52, hollow core floor beams 46, installed flooring, and exterior sheathing is thejoist space 54. The importance of thisspace 54 will become more apparent below. As will be described in more detail below, ambient air within the building enters thehollow wall panels 44 and is returned through thejoist space 54 and hollow floor beams 46 to the plenum. - The hollow
core wall panels 44 may include insulation materials designed to help increase the R-value of the panels, thereby helping to prevent internal heat loss during colder months. Thewall panels 44 may further include wiring chases and ventilation channels, to achieve maximum flexibility. -
FIG. 2B shows an enlarged, detailed view of one of thesolid wood columns 42 interfacing with a reinforcedconcrete pier 56 supporting the structure and further illustrates the floor structure, allowing for air to return to the plenum. Asteel base plate 58 is provided in connection with each joint, eachsteel base plate 58 configured to carry thecolumn 42 and floor beams 46 and secure thecolumns 42 to the reinforcedconcrete piers 56.Anchor bolts 60 are used to secure thesteel base plates 58 to theconcrete piers 56, thereby maintain the integrity of the structure. Theslots 50 located on either side of thesolid wood columns 42 accept and retain thewall panels 44 therein. - In the embodiment shown in
FIG. 2B , aplywood sheath 62 is laid on the frame created by the hollow core floor beams and support beams. On top of theplywood sheath 62 is finished flooring 64, preferably made of wood. Thisplywood sheath 62 and the exteriorgrade plywood sheath 66 disposed on the underside of the frame effectively seal the frame andjoist space 68 from the outside air as well as from the air inside thebuilding 10. - As mentioned above, the floor beams 46 extending from the joints to the central hearth system have a hollow core, allowing air to flow from the wall panels back to the central hearth system. Furthermore, an
aperture 70, located near the joint, is defined within each of the floor beams 46. Theseapertures 70 are configured to allow air, which is disposed within thejoist space 68, to pass from thejoist space 68 into thefloor beam 46. Thus, ambient air within thejoist space 68 may enter the hollow core of the floor beams 46 and return to the plenum (not shown), where it is forced through the fire box by the variable speed fan, reheated, and re-distributed throughout thebuilding 10. -
FIG. 2C shows a cross-sectional view of thebuilding 10 in accordance with one embodiment of the present disclosure. At either end of thebuilding 10, one of thejoints 40 is shown whereby thewood columns 44 are shown anchored into theconcrete piers 56. Additionally, exposedinterior columns 45 within thebuilding structure 10 show the interior facia ofcolumns 44 ofbuilding 10. Furthermore, the 360open hearth system 100 is at least partially enclosed via heatresistant glass enclosure 108 including anaccess door 108.Apertures 105 in thehearth system 100 adjacent to thefire box 107 allow for heated air to escape thefirebox insert 107 and circulate throughout thebuilding 10. Furthermore,openings 72 located at the top of each hollowcore wall panels 44 allow ambient air to enter the hollow core wall panels and eventually return to theplenum 102. It should be noted that theopenings 72 located at the top of the hollow core wall panels are open to the interior of the building only. The interior of the building is sealed off from the outside, to ensure that heated air does not escape the building and also to make sure that cooler air does not enter the building. - In the embodiment shown in
FIG. 2C , thehearth assembly 100 andchimney 38 are shown centrally disposed within thebuilding structure 10. Aconcrete fireplace foundation 110 andfooting 110 are located beneath thehearth system 100 andchimney 38, to support thehearth system 100 andchimney 38. - With continued reference to
FIG. 2C , the ambient heat recovery system of the present disclosure will be described in detail, where the arrows indicate the flow of air throughout the building. The centrally locatedhearth system 100 is secured within aconcrete fireplace foundation 110 and extending upwardly through theroof 20 of thebuilding 10 is achimney 38 with aflue 39 defined therein. The fireplace portion of thehearth system 100 includes afire box 107. Thefire box 107 is configured to retain a fire therein and further configured to receive returned air from theplenum 102. Theplenum 102 is located below thefire box 107 and is configured to receive the returned air from the hollow core floor beams 46. Afan 106 is located between thefire box 107 and theplenum 102. Thefan 106 is configured to direct the returned air received by theplenum 102 through thefire box 107, such that the air is heated by the fire withinfire box 107 and dispersed throughout thebuilding 10. Once the air is heated by the fire contained within thefire box 107, the air escapes throughapertures 105 and is evenly distributed throughout the building, due to the 360 degree, central location of thehearth assembly 100. The smoke from the fire exits the building through theflue 39 in thechimney 38. - When a wood-burning or other suitable fire is started in the
fire box 107, heated air exits thefire box 107 throughapertures 105, thereby heating thebuilding 10.Fan 106, which may be a variable speed fan, helps distribute the heated air evenly throughout theentire building 10. As shown by letter A, the heated air is exiting the hearth assembly and entering the living space. The heated air continues to travel, as indicated by the path of arrows at location B. Eventually, the heated air, which emanated from the centrally locatedhearth system 100 reaches the furthest parts of thebuilding 10, noted as at location C, which is around the perimeter walls of thebuilding 10. As the heated air travels along the above described path, from A to C, for example, it mixes with cooler air, thereby increasing the temperature of thebuilding 10. This ambient air will reach theopenings 72 located at the top ofwall panels 44 and enter the hollow core of thewall panel units 44. The air travels down the hollow core of thewall panel 44 as shown by the arrow segment D. When the air reaches the base of thewall panels 44, at location E, it enters thefloor joist space 68 via a opening located beneath the sheathing and flooring. Once located in the floorjoist distribution space 68, the air may flow into the hollow core floor beams 46 throughapertures 70. The hollow core floor beams 46 lead from the outer perimeter of thebuilding 10 to the centrally locatedhearth assembly 100, where they are in fluid communication with theplenum 102, thereby allowing the ambient air to return to theplenum 102, for example, via path F. It is preferred that theplenum 102 is asteel plenum 102, however it is also envisioned that other suitable materials may be used. - Once the ambient air is returned to the
steel plenum 102, as described above, it is transferred, at location G, via thevariable speed fan 106 back through thefire box 107, where the air is re-heated. Thevariable speed fan 106 also assists in forcing the re-heated air back through theopenings 105 in thehearth assembly 100, as shown by arrow segment A, and thus the ambient heat recovery system just described repeats itself. As can be appreciated by one skilled in the art, the above-mentioned process continues indefinitely, heating the building and returning previously heated air, until the fire or heat source is no longer burning. -
FIG. 2D shows an enhanced view of the wall and floor details which provide for the return of air to the centrally disposed hearth assembly. As shown, the air flows through the hollowcore wall panels 44, where it eventually enters thedistribution space 68, through a small opening at the base of thewall panels 44. The air then flows from thedistribution space 68, through theaperture 70 and into the hollow core floor beams 46, where it is then returned to the hearth assembly via the hollow core floor beams 46. - Now referencing
FIGS. 3A-D , the uniquely designed wall panels and floor beams of the present invention are illustrated.FIG. 3A shows an elevation view of the typical hollow core wall panel unit in accordance with the present disclosure, whileFIG. 3B is an elevation view of the cap of the hollow core wall panel.FIG. 3C is an elevation view of the base of the hollow core wall panel andFIG. 3D is an elevation view of the hollow core floor beam in accordance with the present disclosure. -
