Abstract:
Combining of ceiling frameworks, and structural members of skylight plenum enclosures in daylighting applications. When daylighting enclosures are designed without enclosure assemblies being directly connected to suspended ceiling types framework, but only extend and connect to the ceiling via the fabric portion of structure. Allowing daylighting enclosures to “float” above the ceiling framework and have minimal impact upon it when connected.  
     Floating daylighting enclosures lend themselves to being connected to divided roof apertures. With the flexibility of capturing roof daylight, without directly contacting roof framing members. Creating daylighting distribution more efficient, and less costly, than daylighting originating from single roof and single ceiling openings.  
     Enclosures fabric sections ends may be relocated to other adjacent openings in ceiling framework, with a enclosure flexibility capability. Plus a mending adaptability inherent to weave and construction of fabrics, when required.

         BACKGROUND OF THE INVENTION  
         [0004]    This invention relates generally to the field of building construction and more specifically to articles of manufacture for and process of transporting daylight through building plenum.  
           [0005]    Originally, daylighting with skylights could be found in buildings. Warehouses for example, without ceilings between roof and floor. This form of daylighting production had low requirements, with less need for tight design specifications. As is now required by Architects when designing complete building envelopes, with daylight as a primary factor. See analysis soft ware called SkyCalc, and find SkyCalc at the following web site info@h-m-g.com, &lt;mailto:info@h-m-g.com&gt;provides for analysis of electricity and money saved when daylighting buildings. Where dollars saved are reported in buildings and Savings by Design, Southern California Edison, of Southern California. Who provide specify performance criteria and incentives to controlled interface of daylight and electric lights. California in efforts of promoting daylighting in commercial buildings. Has awarded a skylight manufacturer Sola tube with incentives for installation of their products. The transcript follows for this web site address.  
           [0006]    http://www.energy.ca.gov/peakload/com_skylight_incentive.html  
           [0007]    Commercial Skylight Incentive Program has $1 million available to commercial customers who want to lower their peak electricity use for indoor lighting by installing Solatube International&#39;s SolaMaster 21-inch model tubular skylight systems.  
           [0008]    Solatube tubular skylights transfer daylight into building interiors. Light passes through an acrylic dome, down a reflective tubing, and through a diffuser to provide interior lighting directly from sunlight. Photo controls are added to switch conventional electric lighting systems off during daytime hours, resulting in lower peak load electricity use. Customers will receive a price reduction or rebate of $56 per installed skylight. Each skylight can save over 500 kilowatt-hours per year and reduce peak electricity demand by 0.22 KW Additional background of the need for suspended ceiling needs is described by information found at New Buildings Institute, Inc. whose web site address is http://www. newbuildings.org/pier/.  
           [0009]    Previous studies have shown that skylighting, or toplighting with daylight, has dramatic potential for saving lighting energy (with cooling energy savings as a byproduct). These include the recently published Skylighting Guidelines. (See Skylighting Tools and Guidelines at SCE&#39;s Energy Design Resources web site (ww.energydesignresources.com).  
           [0010]    These studies have shown examples of good (and sometimes bad) toplighting, but they have nearly all been one-of-a-kind designs. In general, most practitioners are quite reluctant to take on the risk of developing one-of-a-kind designs for a ceiling system that must integrate several components from different manufacturers (skylight, ceiling and light well, electric lighting, photocell controllers, air diffusers, etc.). The Subcontractor knows of no work that has proposed prototype designs, except in the most general sense, for integrated ceilings that could be standardized and repeatable. The Subcontractor&#39;s preliminary discussions with Armstrong Ceilings, the largest manufacturer of ceiling systems in the country, indicates that neither they nor any other manufacturer of ceiling systems is likely to undertake this kind of integrated design development. They would, however, be willing to participate in the development of industry standards for integrating different manufacturers&#39; products, provided there was leadership and impetus for such an effort. These standards would entail development of design standards and specifications for interconnection details between components (e.g. skylight-to-light-well connections, or photocell to controller-to-dimming-ballast connections).  
           [0011]    About 60% of nonresidential floor space in California is directly under a roof, and 90% of new floor space is single story construction. There is, therefore, a huge potential floor area suitable for toplighting applications. Skylighting is easy to do. Nevertheless, it is not widely applied by building designers or owners because each skylighting design requires the careful integration of ceiling system, skylight, light well, electric lighting, photo control, and, often, air distribution systems. This problem has been discussed for over fifteen years within the building science community, yet the resources (federal or industry funding) has never materialized for this work to take place In both amounts of foot-candle requirements and control sophistication of daylighting. Ceilings in buildings, including types of ceilings suspended from roof structures. Were not recognized as opportunities for daylighting. And existed outside the realm of affordable, or practicable daylighting for numerous reasons. Existing physical obstructions restricting straight paths, for daylighting shafts, in vertical directions. Small semi-flexible shafts typical of tube type products lack the volume necessary to honestly turn off the building s lights. For instance, integration of electric fixtures and other types of pipes, wires, ducting. Additionally, general interior finish aspects of suspended ceiling products such as surface finish, and non-interruptible wire connections from roofs to suspended ceilings. Elements of the grid framework systems resistant to impacts such as weight, movement, or deformity. Process in which framework of suspended ceiling installation requires complete assemblage, providing dimensional integrity. Effectively restricting installation labor, for shaft installations. And resistance to removal and replacement of grid remembers. Have eliminated daylighting from mechanical trades involved in plenum products. Existing as the foundation, for the layout of the light fixtures. Commonly referred to in the building trades as reflected ceiling plan. A design criteria driven by the requirements of electric lights, and their distribution throughout the utilized space. As a result of these complexities, daylighting integration for suspended ceiling has needs of utilization from the design segment of construction practices. With modern demands for energy efficiency and improved occupant living and working environments. Evidenced, by published daylighting programs such as SkyCalc, and extensive daylighting studies indicating improvements in student scores, in day lit classrooms. The lack of integration between daylighting processes and suspended ceiling applications, establishes solution needs. Coupled with numerical square footage of existing suspended ceilings commonly found throughout construction sectors. Requires restrictive elements of daylighting buildings, with suspended ceiling, to be overcome.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0030]    Detailed descriptions of the preferred embodiment are provided herein. It is to be understood, however, that the present invention may be embodied in various forms. Therefore, specific details disclosed herein are not to be interpreted as limiting, but rather as a basis for the claims and as a representative basis for teaching one skilled in the art to employ the present invention in virtually any appropriately detailed system, structure or manner. Typical buildings with suspended type ceilings. Illustrated in section views of FIG. 15 describing both building section  152 - a.  Plus a ceiling to roof section  152 - b.  Building sections  152 - a  and  152 - b  illustrate a inventive approach of transporting sun light from outside to inside a building, daylighting interior spaces.  
         [0031]    Section view of FIG. 15, were in description of building elements  152 - b  are illustrated. Exterior light transmitting unit, skylight  141  located on top of a building. Situated beneath the skylight is roof curb  156  making a connection between skylight and roof. Building roof superstructure  121  is the exterior top of the building. Drawing  152 - b  describes corrugated enclosure detail FIG. 8. Drawing  152 - b  additionally illustrates channel enclosure detail FIG. 12. These two enclosures built of different materials and configurations. Illustrate enclosure applications, of various angles and directions, below a skylight. When a single opening at the skylight is divided apart into two separate enclosures. This physical division is referenced to as split enclosures. The dividing point for split enclosures is located inside the curb. Inserted as framed member  147  positioned below skylight. Section view of building including floor to roof FIG. 15 drawing  152 - a.  Metal roofing material, on top of the building drawing  154 - a.  Is a common covering material for nonresidential buildings. This type roofing material, made of many configurations, materials, and finishes. Provides for daylighting, when panels referred to light transmitting panel  154 - b  are used. Light transmitting panels, made of various types of glazing materials including fiberglass, polycarbonate, and acrylic plastics. When designed and fabricated, as a replica, for insertion into metal roofs, require specific installation. Fitting into the opening made for their insertion. Requires placement under the metal roofing above their location, and over the metal roofing below their location. This simplicity of installation, and lack of vertical curb  156 . Creates high rainwater runoff, and easy of retrofitting, for daylighting. Produced in random lengths, that tended be long narrow rectangular shapes. Light transmitting panels in metal roofs, direct daylights orientation for building interiors. To long rectangular design outcomes driven by particular spatial and dimensional characteristics of roof panels. Similar long narrow daylighting production at suspended ceilings is required. Compatible, linear transfer at ceilings produces daylight sources capable of length-wise spreading of daylight onto interior walls. For example Skylight enclosure  41  in drawing  152 - a  illustrates a enclosure, located parallel to a building wall. Connected to the bottom of light transmitting roof panel  154 - b.  Skylight enclosure  41  terminates at suspended ceiling  16 , With attachment characteristics and finish similar to preceding paragraph. Turning now to section view FIG. 13 where daylight enclosures are shown angled between roof member  121  and suspended ceiling framework  16 . The enclosures of either corrugated or channel constructions are typically made of reflective fabric  41  membrane. These skylight units, describe directions of sunlight from summer to winter orientations. Enclosure shafts repeat the winter sun angle, providing as much daylighting exposure as possible. Whereas the enclosure shafts receiving the summer sun provides a cut off of direct daylight. While increasing daylights extended travel of reflection off reflective fabric  41 . This additional traveling, besides reducing heat from the daylight while bouncing. Also affects ultraviolet rays that are diminished with additional surface contact. Daylight enclosures terminate at finished ceiling frameworks, of numerous products. Ceiling frameworks may comprise steel T- bar construction. With main runners and cross tees, comprising major parts of the system. Hung by wires from the roof members, and supported on the perimeter by connection to building walls. Many other kinds of products can provide similar terminal points that floating skylight enclosures connect to. These types of frameworks, with one description type, suspended ceiling t bar  16 , FIG. 1. Are common construction products, in nonresidential markets separating plenum from space below this framework or grid. As these frameworks&#39; contain light transmitting panels, louvers, and various other light management products. Movement and transporting of daylight from the exterior to the interior of the building is accomplished. This over view, is a foundation perspective for the preferred embodiments, which follow.  
         [0032]    Preferred embodiments for the present invention are defined by consideration to quantities of plenum obstructions, of a particular application requiring daylight. The following preferred embodiment description, would be utilized when plenums have little mechanical obstruction. Not, impacting enclosure system installation access to roof and ceiling openings. Or when design criteria of new construction, provides allowances for daylight enclosures. And design layouts of other plenum mechanical obstructions are designed to avoid enclosure locations. This preferred embodiment, is described as corrugated enclosures, “floating” both above the ceiling, and below the roof frame members. Floating above ceiling shown in section view FIG. 9 is corrugated enclosure bottom. While channel enclosure systems illustrated in section view  12  shows bottom portion floating above t bar suspended ceiling  16 . These enclosures also float below skylight curb  156  and roof member  53  as shown in section view of FIG. 15. These connections are detailed in FIG. 16 where the curb  156  depicts attachment of enclosure corner wire from corrugated enclosure end. Wrapped around one type of wire anchor  164 , finally, secured to curb by opposed leg staples  12 .  
         [0033]    Additionally, channel framework  102  is attached to curb  156  at stud material cut and bent  104 . And fastened to curb with temporary large headed roofing nail. Flange  104  being cut, from main body of channel enables the otherwise rigid stud to have movement ability in one direction while the nail provides movement in other directions.  
         [0034]    A typical embodiment of the skylight system of the present invention is illustrated in FIG. 1 and FIG. 2 in isometric views. What is described in FIG. 1 suspended ceiling T-bar  16  is the main element of suspended ceilings. And produced by numerous manufacturers, found commonly in nonresidential buildings. These t bar sections, that include main runners and cross tees. When assembled in a building space and supported by wires from roof members above. They create a finished ceiling framework known as suspended ceiling grids. Many ways and configurations of connecting the main runners and cross tees exist, from different products. Basic framework parts and connection techniques by different manufacturers, are not shown here. The sequence of construction for suspended ceilings starts with perimeter right angle attachment. Main runners use this perimeter as base upon which main runner ends sit. Tolerance of installed product grids is in fractions of inch, criteria. Making them fragile and susceptible to damage, if affected by forces other than their normal processing while being erected. When enclosure floats above these delicate frameworks, with minimal weight and connection impact. the possibility of problems or damage to t bar grids is greatly reduced. Cross-Ts snap into main runners, according to ceiling tile grid layout. Dimensional ceiling tiles are dropped into the main runners and cross t rectangles. Occurring at 2′×2′ and 2′×4′ nominal dimensions commonly. Suspended ceiling framework, when assembled has internal stress, deflections, and load capacities. Engineered into product and installation procedures, by manufacturers to accomplish these and other design criteria. Seismic provisions for instance, being integrated into complete design needs. This skylight enclosure invention unites suspended ceiling products framework and accessories into daylighting enclosure systems. Has a window for labor to access this framework, specifically, at this phase of construction. This window and its awareness in the design process, scheduling, and contracting. Interacts with the need for the complete ceiling framework field to be connected and self-supporting. Installation starts when individual frame members, cross-T&#39;s only are removed, particularly when enclosures are angled, or include more than one 2×4 bay. Gaining access to plenum environments where enclosures will be erected and hung. In a further approach, enclosures are attached, before suspended ceiling framework is built. Permanently to upper end of enclosure at roof and curb, while enclosure bottom temporally hangs freely in approximate location of their final connection to t-bar suspended ceiling. This upper attachment is illustrated in FIG. 16 with the two preferred embodiments, corrugated and channel systems, framed and finished. Illustrated in isometric view, skylight curb  156 . These upper attachments are completed from both above and below the curb. Illustrated in FIG. 1 are both a drawing and detail of pneumatically driven steel staples. The staple illustrated, is described as opposed leg staple  12 . With the magnified detail, of this staple chisel point  13  illustrating the inclination and sharp point of this type staple. These are non-stock items from fastener supplier, Senco Fasteners. Standard roofing staples have tips shaped to form a “V”. Less sharp, and designed to penetrate straight into materials being fastened. An extremely sharp point  13  allows the legs of the staple to easily penetrate light gauge metal. Plus light gauge metal in conjunction with layers of wood, a benefit described later. The FIG. 2 opposed leg staple  24 - a  portrays staple after having been fired, from pneumatic roofing staple gun. Air assisted guns as used for fastening shingles and flashing in roofing operations. Is equipped with a gauge that locates where staples enter the t-bar bulb  26 . Positioning staples to be driven directly above and into t bar bulb  26 . This insertion enables the legs of the staple to be spread apart. Caused by the sharp angle at the tip of the staple leg moving the leg constantly away from the staple body. This action of the staple legs, allows the staple body to capture a bottom section of reflective fabric  41  of skylight enclosure. Securing and locking itself on to the bulb  26  as metal to metal fastening arrangement. Reflective fabric  41  from skylight enclosure FIG. 8 continues down, FIG. 2 t bar material, ending below t bar bulb  26 . Utility knife blade, traveling along right angle grove for knife-edge  28  of T bar, trims excess fabric  41 . Loose fabric ends, are then attached to adhesive  27  located below bottom edge of t bar bulb. Adhesives of many varieties are applied upon web  29 , with silicone, two-sided tape, hot melt glue, and are adhesive for example. Adhesives, when applied as fluid type materials, are applied from caulking guns. Dispensing tip of caulking guns travel along bottom portion of the t bar bulb as an application guide. Embedding loose fabric ends to adhesive  27  of T bar section, creates a dust tight seal between inside of skylight enclosure fabric, and suspended ceiling framework  16 . While maintaining clearance necessary for dropping in of light diffuser panels. This size difference between panels and framework, necessary for panels fitting into rectangular grid framework.  
         [0035]    Additional descriptions of corrugated enclosure assembly can be seen in isometric and detail views FIG. 4. Previous elements in FIGS.  1 - 3  have been combined to form skylight enclosure assembly. This combination of elements, is achieved when fabric or sheet type materials. With one or both sides of these materials, having a surface finish that is highly reflective. Enclose a perimeter space, between roof and ceiling openings, transporting daylight as a process of reflection. Light passed along from reflective fabric  41  is kept moving, with little loss of light, when material reflectance is within mid to upper 80% range.  
         [0036]    Composition of reflective fabric FIG. 4 drawing  41  products can be made of different base material layers, and insulating properties. Reflective fabrics can be used with insulating properties, increasing energy performance of skylight enclosure in relation to plenum-conditioned air. Base sheet materials, of both products can be made of fiberglass cloth, scrim mounted vinyl, plain vinyl, and heavy-duty craft paper backing. Applied to these backing sheets, are various quality grades and percentages of thin skin aluminum facings. Providing a reflective surface, with highly reflective optical properties. High quality aluminum skins, reduce light loss as daylight travels through enclosure system. Specialty companies such as Dura Coat Co. manufacture single sheet products, one product, fiberglass base sheet reflective fabric, have strong capacity for resistance to tear and puncture. While allowing trimming and cutting, to be done with little manual effort. Production sheet materials are supplied in continuous rolls, in widths up to 54 in. This common dimension fits the framework openings of grid systems, with small waste allowances. For on site installations, of channel enclosure construction, manageable roles are held in dispensers close to fabric application areas. Reflective fabric, insulating type sheet products are manufactured by Reflectix Insulation, who provide a dead air space bubble between layers of reflective fabric. Determined by climatic conditions, extra layers of insulated reflective fabric, is easily accommodated by present invention assemblages. By either, preferred embodiment skylight enclosure systems, corrugated and channel. When the corrugated enclosure assembly encloses space used by the daylight, FIG. 8. Fastening, FIG. 4 between corrugated sheet material  31 , and enclosure sidewalls reflective fabric  41 . Can be accomplished with physical connections and adhesive techniques, not limited to this preferred embodiment. Fastening by mechanical application, with the clinch staple  34 , wherein staple legs, when bent over detail  34 , sandwich the body of staple against corrugated sheet material  31 . Containing reflective fabric  41 , and securing it from moving. Restricting movement between materials extends useful life of materials. To reinforce and augment the permanence necessary to stabilize the surface connection between materials. Secondary securing of reflective fabric  41  to corrugated sheet material  31 , is achieved in adhering one material to another. This accomplishment by adhesives of different compositions, for instance silicone, butyl tape, two- sided carpet tape, requires compatibility with polycarbonate plastics. Adhesive application  48 , bonds reflective fabric  41  onto the corrugated sheet material  31  by gluing or other attachment bonding. In positioning of enclosure assembly, corner members provide for adjustment to site requirements. Seen in FIG. 4 enclosure corner wire  44 , one of enclosures four corners. Provides for spatially locating and defining corrugated skylight enclosure FIG. 8 section view. Provisions for adjustment, of the enclosure on any of the corrugated sheet corner panels. Is obtained by inserting, according to needs, corner wires  44  into appropriately located channels sequence  33 . Preferred embodiment parts, compatible with both skylight enclosure configuration and elements for suspended ceiling hardware uses, FIG. 5. Some length of T bar hanging wire  22  is shown, with corresponding wire attachment units designed to provide for anchoring and attached directly onto hanging wire  22 . Grommets  36  connected to adjacent wires utilize simple devices, for creating anchor points. These devices incorporate hanging wires spring clamp  54 , or other types of hanging wire fasteners  56 . These perimeter-anchoring devices, can be used for positioning and stabilizing skylight enclosures that have angles and directions not in plumb or normal vertical positions. As illustrated in FIG. 15 drawing  152 - b.  These connections, to either enclosure sides and from above, is used to achieve designed angles of skylight enclosures. As illustrated in FIG. 9 where spring clamp  56  secures hanging wire at round pipe spreader section  95 . An alternative for securing angles of skylight enclosures at connection for pipe spreader section  95 , would be that hanging wires to passing through pipe spreader corner  96 . And returning back up to wire above corner section there tied around and fastened. Another function of final positioning for skylight enclosures, the bottom of which is shown in FIG. 9 is described in FIG. 5 drawing element roof framing member  51 , portrays the supporting framing member of roof. Connected to roof member  51 , fastening device, roof member fastener  53 , is shown attached by screw threads into roof member  51 . While tension pole wire  55 , is connected to an hangs down below fastener  53 . Inserted over tension pole wired  55  is light gauge conduit type material, tension pole  57 . The function of the tension pole  57  can be more readily understood by investigating illustration FIG. 12 cross section of skylight enclosure, where tension pole  57  is connected to pipe spreader corner and roof member  51 . Securing wire travels back up to roof framing members or spans over to adjacent hanging wires spring clamps  54  attached to random T bar hanging wire  22 . Correct skylight enclosure positioning, is completed, when tension pole wire  55  is secured, at final location.  
         [0037]    Corrugated enclosure preferred embodiment is illustrated in isometric and detail views FIG. 3 depicting corrugated sheet material  31 .
