Definitions
- the present invention relates to a modular building system wherein a building's utilities are distributed from a prefabricated core wall that is equipped with a computer-based controller for managing the utilities.
- the US housing construction industry is one the largest sectors of the economy. This sector includes building additions or alterations to existing homes, construction of custom homes, and on-site assembly of modular and prefabricated houses.
- the types of businesses servicing this sector include custom builders, general contractors, design builders, engineer-constructors, joint-venture contractors, turnkey contractors, and construction management firms. These different businesses face considerable competition, especially relating to construction costs and job scheduling.
- One method to reduce cost and shorten construction schedules is to use prefabricated units or modules. This approach not only reduces the total amount of labor involved, but allows for relatively unskilled laborers to operate on-site while skilled laborers (i.e. plumbers, electricians, etc.) are concentrated at central locations, such as manufacturing and assembly facilities.
- the use of prefabricated modules also reduces or eliminates the need to coordinate the schedules of electricians, plumbers, and others skilled in their craft with the schedule of the general contractor.
- modular units are built as core walls, for example U.S. Pat. No. 4,221,441 (Bain) (showing a prefabricated kitchen/bath/utility system that is built as three separate modules) and U.S. Pat. No. 3,590,393 (Hollander) (showing a prefabricated bathroom component built to accommodate a specific appliance).
- These modular units typically incorporate utilities such as plumbing (hot/cold water, sewage, etc.) and/or electrical wiring, within one or more wall structures to which conventional home appliances can be attached.
- these modular units can be incorporated into the structure of a residential building's interior layout, they are inflexible with respect to their spatial arrangement and are not designed with consideration of the building's interior layout as a whole.
- modular units known in the art ineffectively utilize the space available within the building.
- these modular units are not readily adaptable to the wide variety of spatial arrangements that are required to maximize the utility and effectiveness of the interior space of both new construction and renovated residential buildings.
- Computer-based control systems have also been developed to manage the mechanical and other systems of a building, such as ventilation, audio/video entertainment, and security systems.
- these control systems are located remotely with respect to the building utilities that they manage.
- conventional control systems may reside on a personal computer or other type of electrical equipment box that is placed in an office, closet, basement, etc.
- controlling the building utilities remotely incurs an extra and needless degree of complexity and cost.
- the present invention solves these and other problems associated with the modular units known in the art.
- Applicants have discovered a novel system for building construction in which prefabricated modules having an integrated control system are used to distribute, at least in part, the building's utilities.
- This system brings together concepts of modular construction with efficient mechanical planning and integrated computer-based controllers to create a unique system for residential construction. Integration of a controller directly into a core wall that houses a utility distribution system increases building efficiency, flexibility, and cost effectiveness over conventional building techniques. Moreover, these modules are readily adaptable to a wide variety of spatial arrangements and, therefore, can be used to optimize the building's interior layout.
- the present invention provides for a compact, easily transportable package of an essentially flat core wall with all essential services preinstalled and attachable prefabricated panelized partitions.
- one aspect of the present invention is a prefabricated modular building system having a core wall that houses a central utility distribution system and a computer-based control system located within the core wall that is capable of integrating and managing the building utilities.
- the building system also has one or more panelized partitions attachable to the core wall via a plug-in fastener device and one or more utility run extension located within the partition wherein the utilities of the utility distribution system and the utility run extensions located in the panelized partitions are mateable via complimentary connectors.
- Another aspect of the present invention is a method of constructing a building comprising the steps of providing a prefabricated core wall in which one or more utility runs are disposed; providing a computer-based control system located within said core wall; and integrating the control system with the utility runs to manage the utilities.

Description
- This application claims priority benefit to U.S. Provisional Application No. 60/548,457, filed on Feb. 27, 2004, which is incorporated herein by reference.
- The present invention relates to a modular building system wherein a building's utilities are distributed from a prefabricated core wall that is equipped with a computer-based controller for managing the utilities.
- The US housing construction industry is one the largest sectors of the economy. This sector includes building additions or alterations to existing homes, construction of custom homes, and on-site assembly of modular and prefabricated houses. The types of businesses servicing this sector include custom builders, general contractors, design builders, engineer-constructors, joint-venture contractors, turnkey contractors, and construction management firms. These different businesses face considerable competition, especially relating to construction costs and job scheduling.
- One method to reduce cost and shorten construction schedules is to use prefabricated units or modules. This approach not only reduces the total amount of labor involved, but allows for relatively unskilled laborers to operate on-site while skilled laborers (i.e. plumbers, electricians, etc.) are concentrated at central locations, such as manufacturing and assembly facilities. The use of prefabricated modules also reduces or eliminates the need to coordinate the schedules of electricians, plumbers, and others skilled in their craft with the schedule of the general contractor.
- The use of prefabricated modular units for construction of residential buildings, such as houses and apartments, is known in the art. Some of these modular units, including those described in U.S. Pat. No. 2,712,863 (Busch), U.S. Pat. No. 3,110,907 (King), and U.S. Pat. No. 4,470,227 (Bigelow), are designed as complete preassembled rooms. Transportation of these prefabricated “boxes of air” from the fabrication site to the installation site is difficult and uneconomical because the units are not compact.
- Other modular units are built as core walls, for example U.S. Pat. No. 4,221,441 (Bain) (showing a prefabricated kitchen/bath/utility system that is built as three separate modules) and U.S. Pat. No. 3,590,393 (Hollander) (showing a prefabricated bathroom component built to accommodate a specific appliance). These modular units typically incorporate utilities such as plumbing (hot/cold water, sewage, etc.) and/or electrical wiring, within one or more wall structures to which conventional home appliances can be attached. Although these modular units can be incorporated into the structure of a residential building's interior layout, they are inflexible with respect to their spatial arrangement and are not designed with consideration of the building's interior layout as a whole. Thus, they are not adaptable to a variety of architectural layouts or features of the building and are principally designed to service only rooms adjacent to the modular unit. Due to their limited flexibility, modular units known in the art ineffectively utilize the space available within the building. In addition, these modular units are not readily adaptable to the wide variety of spatial arrangements that are required to maximize the utility and effectiveness of the interior space of both new construction and renovated residential buildings.
- Computer-based control systems have also been developed to manage the mechanical and other systems of a building, such as ventilation, audio/video entertainment, and security systems. Conventionally, these control systems are located remotely with respect to the building utilities that they manage. For example, conventional control systems may reside on a personal computer or other type of electrical equipment box that is placed in an office, closet, basement, etc. However, controlling the building utilities remotely incurs an extra and needless degree of complexity and cost.
- The present invention solves these and other problems associated with the modular units known in the art.
- Applicants have discovered a novel system for building construction in which prefabricated modules having an integrated control system are used to distribute, at least in part, the building's utilities. This system brings together concepts of modular construction with efficient mechanical planning and integrated computer-based controllers to create a unique system for residential construction. Integration of a controller directly into a core wall that houses a utility distribution system increases building efficiency, flexibility, and cost effectiveness over conventional building techniques. Moreover, these modules are readily adaptable to a wide variety of spatial arrangements and, therefore, can be used to optimize the building's interior layout. In addition, unlike other modular approaches in which a complete prefabricated room is shipped, the present invention provides for a compact, easily transportable package of an essentially flat core wall with all essential services preinstalled and attachable prefabricated panelized partitions.
- Accordingly, one aspect of the present invention is a prefabricated modular building system having a core wall that houses a central utility distribution system and a computer-based control system located within the core wall that is capable of integrating and managing the building utilities. In a particularly preferred embodiment of this aspect of the intention, the building system also has one or more panelized partitions attachable to the core wall via a plug-in fastener device and one or more utility run extension located within the partition wherein the utilities of the utility distribution system and the utility run extensions located in the panelized partitions are mateable via complimentary connectors.
- Another aspect of the present invention is a method of constructing a building comprising the steps of providing a prefabricated core wall in which one or more utility runs are disposed; providing a computer-based control system located within said core wall; and integrating the control system with the utility runs to manage the utilities.

The prefabricated core wall and panelized partitions of the present invention are suitable for use in modular or conventional construction, can be produced in a variety of finishes or unfinished, and can be manufactured and shipped with or without common residential appliances and fixtures, such as sinks, tubs, toilets, cabinets, etc. The most common use for the invention is in residential buildings, such as single family homes, duplexes, condominiums, town homes, apartment complexes, assisted living communities, hotels, mobile homes, and the like. However, those skilled in the art will appreciate that the invention may be adapted for other applications as well, including office buildings, hospitals, and the like.
- Thus, in one aspect, the system comprises a prefabricated modular core wall that houses a central utility distribution system and a computer-based control system that is disposed within the core wall and that is capable of integrating and managing the utility distribution system.
- According to the present invention, the core wall serves as a central utility distribution source. An example of an embodiment of a central utility distribution system in a core wall is illustrated in
FIG. 1 , wherein acore wall 10 houses utilityruns including HVAC 16,120V electricity 22,hot water 24,cold water 20, andsewage 26. While the embodiment shown inFIG. 1 includes five utilities, it is understood that the core wall may house any utility. Examples of other such utilities include, but are not limited to, natural gas, radiator hot water, radiator steam, telecommunication lines (including automation of building utilities), coaxial data cables, 240V electricity, water deionization, water purification, air purification, security cameras, motion detectors, smoke and dangerous gas detectors, telecommunications, electronic data transmission and reception, and audio and video entertainment. Also, the utility run layouts shown inFIG. 1 is only exemplary. Examples of other utility run layouts include the plumbing runs shown inFIG. 3 , and the electrical runs shown inFIG. 4 . The core wall of the present invention can accommodate any utility run layout that would be practically feasible. - The present invention utilizes a computer-based control system embedded in the core wall to manage one or more of the building's utilities housed therein. In certain preferred embodiments, the controller manages all of the building utility system. The controller comprises a central processing unit, an operating system, and input/output data ports that are in communication with input and/or input/output devices such as solenoid valves, electropneumatic and electric-motor actuators, variable speed drives, thermostats, home entertainment centers, touch screen displays, digital data ports, and the like. The controller and ancillary control components may be of any type that are feasible for use for controlling building utilities. Operating systems for such controllers are commercially available from vendors such as Homeseer Technologies and Microsoft.
- Referring to
FIG. 14 , shown is an embodiment of a core wall 10 (depicted, for clarity, as a dash-dotted line) having an integrated computer-basedcontroller 100 which manages all of the shown building utilities, includinghot water 24,electricity 22,security system 112/114,smoke detector 112/116, andlighting 18/120. For example when hot water is desired, a user opens a hot water valve (not shown) at a use point, such as a sink (not shown). Opening the valve starts the flow of water through thehot water line 24 and the water flow and corresponding temperature is measured by a pressure transducer/thermometer 108. The pressure transducer/thermometer sends a signal to the controller viachannel 110 b (indicated by a dashed-line). Channels to and from the controller may be of any suitable form, but are preferably electrical or wireless. When the controller receives a signal that hot water is in demand, it sends a signal toelectrical switch 106 a alongchannel 110 c so that electricity from theelectrical line 22 will be provided to anelectrical heater 104. - Other building utilities are controlled in a similar manner. For example, when the
security motion detector 114 senses motion, a signal is sent to the controller alongchannel 110 h. The controller, in turn, sends a single along 106 f toelectrical switch 106 b which activates analarm siren 112. When thesmoke detector 116 senses smoke, a signal is sent to the controller alongchannel 110 g and the controller again responds by sending a signal alongchannel 110 f to activate thealarm siren 112. The controller manages the buildings lighting, in part, by signals received alongchannel 110 e from a light-level detector 120 and by signals sent alongchannel 110 d todimmer switch 106 c which activates/deactivates thelighting fixture 18. An operator can send and receive data to and from the controller along channel 1110 a via an operator interface, such as avideo display 102. - Utilities that are distributed via the
core wall 10 are channeled through utility runs constructed of conventional materials such as insulated copper wire or conduit suitable for electrical wiring, copper tubing or CPVC for hot and cold water, PVC for sewage, and iron piping or flexible metal tubing with plastic coating for natural gas and synthetic propane, and the like. The core wall and associated utility runs are built off-site, but can easily be installed on-site without need for skilled labor. - Each utility run disposed within the core wall has an entrance point and optionally one or more egress points. That is, each utility run within the core wall has an entrance point for receiving the utility from a point of origin and has one or more egress points for connecting the utility either to subsequent distribution runs via a utility run extension interface or to a point of use via a termination interface, or to both. In general, the terminal interfaces are located along the
front 12 of the core wall. The utility run extension interface comprises conventional mateable connectors that enable the utility run to be quickly and easily connected to a complimentary connector on an extension of the utility run. As will be described in more detail below, these utility run extensions are disposed within panelized partitions which are attachable to the core wall, thus providing, in part, the means for a simple and flexible system of building construction. - In the embodiment depicted in
FIGS. 1 and 2 , theHVAC run 16 has anHVAC entrance point 30 which can be, for example, flexible, sound-dampening supply tubes, anHVAC extension interface 32 comprising a mateable connector, which can be, for example, “T”-connectors, and an HVACend terminal interface 34, which can be, for example, a ventilation register or grill. Also depicted inFIG. 1 , the 120Velectrical run 22 has anentrance point 48 which can be for example 12 gage insulated copper wire, anelectrical extension interface 50 comprising a mateably connector, which can be, for example, Marrette connector, and aterminal interface 14 which can be, for example, a standard 2- or 3-prong electrical outlet.FIG. 1 further depicts hot and cold water entrance points 44 & 46, respectively, and extension interfaces 36 and 38, respectively, andsewer entrance point 40 andexit point 42 comprising mateable connectors, which can be, for example, male/female compression fittings, male/female screw fittings, and the like. Alternatively, terminal interfaces of the present invention can be rough-ins for appliances such as electric ranges, gas dryers, and the like. In certain preferred embodiments, all of the utility interfaces are located above the floor level so as to allow for installation of the core wall onto an existing foundation, such a poured concrete foundation. - In certain other embodiments, the core module concept incorporates a simplified coordinated plumbing riser system including waste lines, vents, and supply lines which can be made in quantity and delivered to the point of assembly as a complete unit, i.e. including all fittings required for fixture and appliance hook ups as well as mateable connectors for tying into the sewer system and for extension of the vent pipes to the roof. Similarly, an electrical wiring harness can be fabricated which drops into the core unit, supplying power and switching to outlets, appliances, and lighting systems. In addition, the house electrical panel can be incorporated into this wiring harness and supplied as part of the total core module.

Yet another embodiment of the present invention is shown inFIG. 5 , wherein thecore wall 10 is integrated directly with appliances such as asink 58, atub 68, and recessedlighting 18. - In certain preferred embodiment, the utility runs disposed in the core wall are encased in a filler, preferably synthetic polymer insulation such as foam insulation packed in oriented strand board. Preferably, the utility runs are assembled within the core wall or assembled separately and then placed within the core wall prior to adding the filler. In certain other embodiments, the core wall itself is formed by assembling the utility runs and then encasing the utility runs in the filler. In this later embodiment, the filler provides, at least in part, the structural support for the core wall. In still other embodiments, the filler may be added during the installation process at the construction site. Specific types of filler that can be used with the present invention include, but are not limited to, expanded polystyrene, rigid insulation, closed-cell foams, polyisocyanurate, and the like.
- In certain embodiments, the core wall includes conventional structural building materials such as wood, galvanized steel, etc. These materials can provide the core wall and the utilities disposed therein with structural support. In certain other embodiments, the structural support of the core wall is derived from the inside and outside skin of oriented strand board (OSB) separated by foam insulation encasing the utility runs. Preferably, the face of the core wall is adapted to receive interior wall construction materials such as sheet rock. In certain embodiments, the core wall functions as a load-bearing wall of the building. In still other embodiments, the core wall includes provisions for integrating with conventional construction, such as plaster flanges, that can be predrilled to easily accommodate wood or metal studs of adjoining conventional walls.
- The core wall of the present invention is also adaptable to different dimensions. Referring to
FIG. 6A , a preferred embodiment of thecore wall 10 is shown wherein the core wall has a horizontal dimension, X, and a vertical dimension, Y. Y is preferably any conventional height of an interior room of a residential building, such as 8 feet, 10 feet, or 12 feet. In particularly preferred embodiments, the value of X is approximately 4 feet. Another preferred embodiment of the present invention is shown inFIG. 6B wherein the horizontal dimension X is some multiple n of approximately 4 feet, wherein n is an integer from about 1 to about 25. For example, where X is 4 feet, the horizontal length of the core wall can be 1X (four feet), 2X (8 feet), 3X (12 feet), 4X (16 feet), and the like. - A core wall with a horizontal length of approximately 4 feet, or some whole multiple thereof, combined with a system of plug-in interior and exterior panelized partitions creates a complete system that allows for simple and uncomplicated integration into an architectural plan. That is, core walls that have a horizontal length of approximately four feet or some whole multiple thereof can easily be represented in a 4×4 architectural planning grid, which is commonly used to design the spatial layout of a building's interior.
- Referring to
FIGS. 7 and 8 A-8E, shown are core walls represented on a 4×4 architectural planning grid, wherein the core wall has a horizontal length of 4 feet or some multiple thereof.
