Definitions

  • This invention relates to controlling solar energy transmittance of a glazing panel and relates particularly, but not exclusively, to such in connection with overhead glazing such as over a roof area of a building.
  • Description of Prior Art In recent times it has been common to glaze overhead areas in buildings. Typically, modern buildings have favoured a central atrium and it has been found extremely difficult to control the solar energy transmitted through the glazing panel so that designers of air conditioning apparatus can accurately predetermine a maximum heat load for the building in such circumstances. In other instances, garden windows have become quite popular and it has been found extremely difficult to control or have a predetermined maximum amount of solar energy transmitted through the overhead portion of the garden window.
  • a further problem with overhead glazing is that at night time, the glazing appears to represent a black sky area in the building. This is particularly so in connection with atriums .
  • a further problem with overhead glazing is that it has been exceedingly difficult for lighting engineers to provide for illumination in the atrium area without resorting to suspended down-lights or alternatively flood lights which apply light directly to the floor area under such glazing.
  • solar energy transmittance can be controlled to a predetermined maximum amount by the application of a patch or pattern as a screen in association with the glazing.
  • the patch or pattern itself can be controlled so that a maximum predetermined amount of solar energy can be transmitted therethrough.
  • the suitable patch or pattern is applied as a screen, it is possible for lighting engineers to, in turn, direct light upwardly onto the glazed area and provide illumination of the patch or pattern in the screen which will, in turn, cause light to be reflected downwardly and provide for an enhanced illumination under the overhead glazing. The black sky effect no longer exists.
  • a method of providing predetermined solar energy transmittance to an area of a glazing panel comprising:
  • a method of providing predetermined solar energy transmittance properties to a glazing panel comprising: (a) selecting a glazing panel material; (b) determining the solar energy transmittance factor of said glazing panel material;
  • Ir-, solar energy transmittance factor of the patch or pattern of the medium in said screen
  • P patch or pattern area expressed in 2 ;
  • T total surface area of said glazing panel expressed in m .
  • thermoforming a glazing panel produced by any one of the aforementioned inventive methods.
  • a glazing panel which has a predetermined solar energy transmittance property wherein said panel comprises a first glazing membrane and a second glazing membrane extending co-planar with said first glazing membrane and a medium between said first glazing membrane and said second glazing membrane which will provide a covering or a patch or pattern as a screen between the first and second membranes.
  • the medium is a printing ink.
  • the peripheral edges of the glazing panel have a peripheral rib thereon.
  • the peripheral rib is such that when an adjacent similar glazing panel is abutted, the ribs on each will be adjacent so that a connecting member can be placed over said peripheral ribs to hold said glazing panels in assembled side by side relationship.
  • the peripheral rib is formed with a snap-lock engaging means and a connector which is used to hold the glazing panels in assembled relationship, has co-operating snap-lock engaging means, whereby the glazing panels can be snap-locked together.
  • Figure 1 is a diagrammatic view of a building with an overhead glazed area
  • Figure 2 shows one example of a typical pattern used to form a covering or screen for use with the glazing panels;
  • Figure 3 shows an alternative pattern;
  • Figure 4 shows an even further alternative pattern
  • Figure 5 shows a side cross-sectional view of a preferred glazing panel
  • Figure 6 shows a close-up side cross-sectional view of two such glazing panels and the method of interconnection.
  • FIG. 1 there is shown a typical example of a building which has overhead glazing 1 incorporating a screen 3 or covering.
  • the screen 3 is of a predetermined area whereby a predetermined amount of solar energy will be transmitted through the glazing 1.
  • the pattern of the screen 3 can be any desired pattern and typical examples are shown in Figures 2, 3 and 4. Other examples may be company logos or pleasing pictures.
  • the requirement is that the screen 3 provide a predetermined amount of solar energy transmittance with the glazing 1.
  • Typical materials from which the glazing 1 can be made are glass - clear or tinted, polycarbonate - clear or tinted, single or multiple skin, acrylic materials - clear or tinted, single or multiple skin, or other suitable roofing materials.
  • the second step is to determine a required decorative patch or pattern for the screen or covering 3.
  • a third step is to select an ink or paint type to be used on the particular glazing material.
  • a colour is chosen to suit aesthetic requirements. By the addition of white or black pigments or silver or aluminium flake to the original colour, a varied percentage of blockout can be achieved.
  • the ink or paint is silk-screened onto the glazing material for accuracy and consistency of the screen.
  • the light transmission factor of the ink or paint can be determined by tests on various samples. Calculation for the solar energy transmission of the finished material is predicted in accordance with the following formula:
  • L, solar energy transmittance factor of the patch or pattern of the medium in said screen
  • L- solar energy transmittance factor of the glazing panel without the screen
  • T total surface area of the glazing panel
  • the glazing 1 By knowing the amount of solar energy transmitted through the glazing 1 it is possible to predict the amount of heat which can be transmitted from the sun into a building and hence it is possible for engineers designing air-conditioning for a building to know a maximum possible heat load and design the air-conditioning system accordingly. Because the screen 3 is provided on the glazing
  • a lighting engineer can, by knowing the reflective area relative to the total area of the glazing 1, be able to predict the amount of light which is required to provide for safe illumination under the glazing 1.
  • the glazing panel 5 is typically of a width of about 600 mm. Other widths can be provided if required.
  • the length is determined by having regard to the length in which the glazing material is manufactured and also having regard to the physical requirement of an installer carrying the glazing panel 5.
  • the glazing panel 5 can typically be manufactured from acrylic sheet. It has a first glazing membrane 7 and a second glazing membrane 9. The first and second glazing membranes 7 and 9 are co-planar and have a screen 11 therebetween. The screen 11 may be printed and/or painted thereon with suitable inks and/or other coatings.
  • each glazing panel has a peripheral rib 31 in the form of a shallow lip formed from each of the first and second glazing membranes 7 and 9.
  • the screen 11 will not extend into the region of the peripheral rib 13.
  • the peripheral rib 13 is provided with a serrated cross-sectional surface on at least the first glazing membrane 7. This permits use of a snap-on connector 15 which has corresponding serrations therein to permit adjacent glazing panels to be held in assembled relationship.
  • first glazing membrane 7 may be of an acrylic material whilst the second glazing membrane 9 may be of a polycarbonate material. Such combination of materials will yield high UV protection whilst considerably strength to the glazing panel.
  • the first glazing membrane 7 and the second glazing membrane 9 may be held to each other by suitable adhesive mediums.
  • first and second glazing membranes 7 and 9 may not be integrally attached to each other as a physical glazing panel but can be assembled relative to each other and held in that relationship by use of a snap-on connector 15.
  • the screen in the form of printing it may be applied as a web of other material.
