Description
    CROSS REFERENCE TO RELATED APPLICATION
  • [0001]
    The present application claims the priority benefit of U.S. provisional patent application Ser. No. 60/715,555, filed Sep. 9, 2005, of the same title by the same named inventor. The entire contents of that prior application are incorporated herein by reference.
  • BACKGROUND OF THE INVENTION
  • [0002]
    1. Field of the Invention
  • [0003]
    The present invention relates to energy saving. More particularly, the present invention relates to solar energy systems. Still more particularly, the present invention relates to systems and methods to enhance the effectiveness of solar energy gain through shade impact improvements.
  • [0004]
    2. Description of the Prior Art
  • [0005]
    Solar energy gain in buildings creates climate control and lighting problems due to heat gain and lighting glare, respectively. Most approaches to managing solar energy gain are characterized by blocking or reflecting the continuum of infrared and visible spectra away from the building using reflective coatings on fenestration and other building envelope surfaces, especially the roof.
  • [0006]
    One approach to managing solar energy gain has been to optimize the building design to capture as much solar heat as possible for space heating in the winter while using shade and vent systems to redirect energy gain in the summer. Referred to as ‘passive solar design’, this approach is intended to capture solar energy in the building when it is needed to offset energy that must be purchased—electricity and fuel—to maintain the building environment. However, passive solar design usually involves large south facing windows and it is difficult to manage solar glare while optimizing heat gain that is absorbed indiscriminately. Also, passive solar design is only useful for new construction, as it must be incorporated into the basic architecture.
  • [0007]
    Traditional shading systems that completely or partially block solar energy including awnings, draperies, shutters, or landscaping may help limit the amount of energy absorbed by the building, but do nothing to capture the energy for useful purposes. Other systems exist for shading that simultaneously apply solar energy for useful purposes. In U.S. Pat. No. 6,421,966, a system is disclosed for wall-mounted louvered blades using a particular geometry to shade a wall only and having a covering of photovoltaic (PV) cells to produce electricity also.
  • [0008]
    Another energy-producing shading system is disclosed primarily for ground shading under US Application Publication No. 2005/0109384. The system is a particular construction for providing shade using a north-south oriented structure that tracks the sun's daily movement and also generates electricity. Integration with a building structure is a challenge due to live and dead loads created by wind and point loading when using load-bearing mounting poles at the interface to the mounting surface.
  • [0009]
    U.S. Pat. No. 4,418,684 discloses a system that actively controls the admission of solar energy into a building via an active shading mechanism to allow selective lighting or passive heating. The invention is building integrated but does not provide for power production or active collection and distribution of heat.
  • [0010]
    Other building integrated devices for collecting solar energy without attention to shading and/or electricity production have been described. U.S. Pat. Nos. 4,215,675 and 4,296,740 describe systems affixed to the existing surface of a roof and may provide cladding. In U.S. Pat. No. 5,851,309 significant yet particular building integrated devices for production of heat and electricity are disclosed without attention to shading.
  • [0011]
    U.S. Pat. Nos. 4,296,736 and 4,020,827 describe similar but not identical sawtooth geometries for using reflectors to redirect solar gain onto an energy collecting surface without consideration of shading or building integration. For both of these systems, heat production is the primary objective. Although PV electricity production is mentioned in U.S. Pat. No. 4,020,827, the curved geometry of the reflector surface would created non-uniform angles of the reflected rays. As a result there would be no effective power increase from the apparent concentration since crystalline silicon (c-si) PV requires uniformity of direct beam sunlight to increase current.
  • [0012]
    The present disclosed invention is differentiated from these other systems by providing the benefits of shading, power and/or heat production and optional building integration using novel constructions and methods. The shading component is inherent and expressly intended in the disclosed invention for building and ground installations. Heat and/or power production is also expressly intended to provide economic value beyond avoiding solar gain due to shading. Finally, the disclosed invention considers requirements for wall, flat-roof, and/or pitched-roof integration with attention to wind loading, avoidance of point loading, and cladding.
  • [0013]
    The present invention includes the use of static or moveable louvers that optimize shading of the underlying surface; the use of reflective, refracting, transmitting, and/or transducing material on the surface of the shade system having exposure to direct or global irradiance; the use of multiple geometries to optimize redirection and channeling of solar energy; and the methods of distributing or dissipating energy loads.
  • SUMMARY OF THE INVENTION
  • [0014]
    An invention is disclosed that shades a building from solar energy gain while simultaneously channeling intercepted energy in the form of heat and/or electricity for useful purposes. The invention is interfaced with the exterior of the building envelope on the walls and/or roof face where solar gain is most significant, notably a complete or partial southerly exposure. The invention is modular so that a number of modules are used together to block solar energy from directly striking building surfaces where solar gain is not managed otherwise. The modular units may be affixed to the building and joined together in such a manner that the system provides a portion of a building's cladding so that the shaded system becomes part of the building envelope.
  • [0015]
    Each module for the invention uses a number of louvers that that track the movement of the sun to optimally absorb solar energy so that it is channeled for useful purposes to effectively manage the building's solar energy gain. Modules may alternatively or additionally employ sheets of opaque material that may be comprised of solar receivers that directly generate electricity or dissipate heat. The modules may be implemented without a floor so that they act as windows or skylights with shutter louvers that allow light to enter the living space.
  • [0016]
    The louvers themselves are composed of electricity generating photovoltaic (PV) cells mounted to a heat absorbing substrate, i.e. a heat sink; conduits or ducts for dissipating heat from the heat sink in order to manage (PV) temperature and electrical resistance; and an optional solar energy concentrator that redirects solar energy entering the aperture of the louver onto the smaller area of the solar energy receiver described by the photovoltaic cells.
  • [0017]
    The heat dissipating conduits of the louvers are manifolded together in the shading system module that is connected to a building's Heating/Ventilation/AC (HVAC) systems. The heat produced as a waste byproduct of the PV cell operation is thus channeled for productive use. The heat channeled from the shading system modules reduces the amount of conventional energy required by the building thereby offsetting conventional energy costs. This energy savings is in addition to the electricity savings realized by not having to purchase from the utility grid since the PV cells on the louvers produce useable electricity. When the building is connected to the grid to supply electricity, the surplus produced by the shading modules turns the building's electric meter backwards and earns credits toward electricity consumed from the grid when the building's demand exceeds supply.
  • [0018]
    Modules within the shading system optionally have the means to track the sun's path in a single dimension, either latitudinally or longitudinally, so that the incident angle of solar energy absorbed by louvers within the modules strikes the louver face at or near 90 degrees in order to maximize energy absorption. The normal incident angle is maintained in the dimension that is orthogonal to the tracking axis about which the louvers rotate.
  • [0019]
    Modules may also be stationary and constructed with reflective material that redirects solar gain from a building onto stationary solar receivers. The reflective material sits in the foreground of a module in the space that is otherwise allowed for shadowing between rows of solar receivers mounted on a building surface, preferably a flat roof. The modules are oriented along an east-west axis. As the sun's altitude changes throughout a year, the southerly reflective surfaces in the “foreground” consistently reflect the sun's incident rays to energy channeling solar receivers on the north edge of the module. The effect is to avoid solar gain on the building surface, preferably the roof, and to increase the solar flux striking the solar receivers having the effect of concentration.
  • [0020]
    The shading system has multiple options for integrating with a building envelope. The invention may be mounted on the outside of the envelope where it has optional flashing to provide a weather tight surface, or it may be implemented to clad the building with a translucent surface over the energy generating modules attached between trusses, studs, or other parts of the building frame.

  • DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
  • [0035]
    FIG. 1 shows multiple modules 10 of a shading system affixed to a sloped roof 20. An optional flashing 30 is also shown for purposes of cladding and integrating with the roof plenum. The flashing is depicted as an angled housing attached to sides of the entire shading system.
  • [0036]
    FIG. 2 a shows details of one type of module 10 that may be used in the shading system invention. The module is covered with a transparent or translucent glazing 11 that protects the contents of the module and provides a weather tight seal especially when the system is integrated with the roof plenum. In this embodiment, energy channeling louvers 100 intercept solar energy thereby shading the building from uncontrolled solar gain. The energy channeling louvers are connected in a header-riser arrangement to parallel tubing that carries an antifreeze solution via a manifold 400 that integrate with a building's hot water, heating, or cooling system when used with an absorption chiller that converts heat load to cooling load.
  • [0037]
    FIG. 2 b shows an embodiment of an energy channeling louver 100 that concentrates energy via a heliostatic reflective trough onto a projector 101 and a solar receiver 130 that is optionally comprised of a photovoltaic laminate assembly with heat dissipating tube 131. Energy is channeled from the solar receiver via an antifreeze filled tube 131 that exits through hole 121. End plates 120 maintain the structural integrity of the trough that rotates about a single axis 122.
  • [0038]
    FIG. 2 c is an end view of the same energy channeling louver 100 and shows a flexible tube 132 that connects the tube behind the solar receiver 131 to the exit hole 121 where the flexible tube 132 joins to the manifold 400 shown in FIG. 2 a.
  • [0039]
    FIG. 3 illustrates a second embodiment of a shading system especially for flat roofs. Mounting platform 200 is affixed to the roof surface or is ballasted with masonry blocks or antifreeze filled containers. An optional transparent or translucent glazing 210 allows light to enter the platform 200 when the platform is mounted to a curb similar to a skylight. Mounting posts 220 support energy channeling louvers 100 that intercept solar energy by tracking the sun's daily longitudinal or latitudinal path via linkage 310 and signal actuated motor 320. Anti-freeze is circulated in tubes in the louvers 100 that are connected via supply and return tubes 400 to the building's hot water, heating, or cooling system when used with an absorption chiller that converts heat load to cooling load. Negative and positive electrical conductors 500 connect optional strings of photovoltaic cells in the louvers 100 to the building's electrical load center.
  • [0040]
    FIG. 4 shows the interface between a shading system's supply and return 401 and 403 of antifreeze that carries heat intercepted by the shading system. In this embodiment, a circulator pump 404 moves fluid through a heat exchanger 402 that is submerged in a domestic hot water pre-heat tank 410. The circulator pump runs when a differential controller 405 detects through thermistor sensors 406 that there is enough difference in temperature between the shading system's heat supply and the temperature of incoming cold water 411 that needs to be heated. When hot water 414 is required in the building, hot water is drawn from tank 413 that stores water at the required temperature via a boiler 415 that distributes its heat through loop 416, Because a series of valves requires that incoming cold water 411 first be pre-heated by passing through tank 410 and into the stand-by tank 413 via pipe 412, the shading system's channeled thermal energy is effectively used to reduce the usage of boiler 415 and its requisite fuel.
  • [0041]
    FIG. 5 shows a building's electrical interface for conducting electricity generated by optional strings of photovoltaic (PV) cells in a shading system. Positive and negative conductors 500 feed direct current (DC) electricity from the shading system into a DC disconnect 591 and into a grid-tied inverter 502 that inverts DC electricity to utility quality alternating current (AC) electricity. AC electricity passes through AC disconnect 503 and into a bi-directional circuit breaker 504 in an electricity service panel 505. Electricity is then consumed by building load 507, or if there is a surplus of electricity generation from the shade system relative to building load 507, electricity passes through the utility meter 506 to generate credits for the electricity account holder. An optional Internet connection 508 allows inverter information about electricity production to be viewed from the World Wide Web 509.
  • [0042]
    FIG. 6 shows a mounting structure 700 for another embodiment of the shading system. Mounting structure 700 may be constructed for a flat roof or it may itself be a building's pitched roof. When located on a flat roof, panel 701 on the bottom of the structure allows ballast to weight it down instead of having to penetrate the roof plenum and risk loss of plenum integrity. The ballast may be masonry block or containers filled with an antifreeze solution. A wind and snow shield 702 on the typically north back side of the structure 700 deflects wind load and prevents snow build-up from the underside of a non-cladding mounting structure. Trusses 703 and ridge pole 704 create bays for shade system modules to be installed, typically in a southerly facing direction. End walls 705 provide structural integrity for the entire structure 700 and are typically covered with a membrane or panel similar to 702.
  • [0043]
    FIG. 7 a describes a mounting structure interface 710 for the shade system. A module encasement 711 is a five-sided enclosure that contains energy channeling devices and has a translucent or opaque glazing 712 with a weatherproof sealant. The encasement 711 sits within framing 703 that is roof trusses in this depiction. A weather cladding interface 715 is described where a lip on top of the encasement walls sits on the framing 703.
  • [0044]
    FIG. 7 b shows the detail of the weather cladding interface 715. The lip of the module encasement 711 sits on the framing 703 to support the weight of the module within framing members. Glazing 712 sits on a bead of weatherproof sealant within a recess of 711. A hold-down strip 716 keeps the glazing in place while a lag bolt 716 attaches the entire assemblage to the framing thereby integrating the shading system as a unit. An alternate hold-down strap 718 reveals a screw fastener with a flush mount head that would not protrude above the plane of the shading system.
  • [0045]
    FIG. 7 c depicts the weather cladding interface on the for the top and bottom ends of the module encasement 711. The lip of the module sits on the framing, in this case a ridge pole or header 704. The framing also has layers of plywood 721 and roofing paper 722 since the module will be interfacing with other cladding materials, notably roof shingles 724. Hold-down strap 718 secures both glazing material 712 that seals the module encasement 711, and also, a flashing strip 723 that maintains the cladding interface with the shingles against rain, snow and other elements.
  • [0046]
    FIG. 7 d shows a top view of two adjacent module encasements 711 that share a common framing member 703 between them. A saw-tooth pattern is employed to allow the encasement to share available surface area on the framing member while fully supporting the weight of the encasement by alternately reaching across the entire width of the framing member. Hold-down strap 718 then fastens the entire system together by holding down one side of the glazing on each module.
  • [0047]
    FIG. 8 a shows a side view of a single shading module 800 having a hinged frame 801 that unfolds on-site for ease of deployment. Reflective surface 802 intercepts and redirects solar energy onto solar receivers 803. The geometry of reflective surface 802 is appropriate to redirecting solar energy arriving from different altitudes of the sun in a range that is specific to the latitude of the installation.
  • [0048]
    FIG. 8 b shows array 810 of multiple shading modules 800 arranged so that a module to the south does not shadow a module to the north. Adjacent modules to the east or west are aligned so that reflective surfaces 802 are on the same plane, and so that solar receivers 803 are on the same plane.
