Presentation Transcript

  1. The Simple Approach to Energy Conservation

  2. This Presentation • U values in Glass • Thermally Broken systems • Gas filling IGU • Ceramic Frit and Shading Coefficients • High Performance multi-function Low e • Round up

  3. U Value calculations • EN 673 The standard method of assessing a U value. • ASHRAE Standard.

  4. U Value Calculations Standard window pane 1000mm x 1500mm Area = 1.5m² Area for calculation DOES NOT include the perimeter. For this pane your U value is based on An area of 1.26m² (84%)

  5. Thermally Broken systems Thermal protection at the Unit edge

  6. Thermally Broken systems EdgetechSuperspacer provides the most energy efficient thermal break at an IGU edge

  7. Thermally Broken systems Thermal protection at the frame edge PVCu

  8. Thermally Broken systems Thermal protection at the frame edge Thermal Break Aluminium Solid aluminium sections typically have a U Value of 1.9 W/m² °C Thermal Break Aluminium Sections typically have a U Value of 1.0 W/m² °C

  9. Thermally Broken systems As much as 15% of the Facade may consist of a framing system designed to carry the glass. In domestic buildings the figure can be higher. Unprotected system edges arelike having a portion of your facade with a solid Portion with an insignificant U value.

  10. Gas Filling Optimum space Space effects on U values

  11. Ceramic Frit and Shading Coefficients Shading coefficients are improved according to the percentage of frit applied. Typical applications are 40% 50% and 60% Those products with low shading coefficients attract the most improvement.

  12. Ceramic Frit and Shading Coefficients Dot Series Line Series

  13. High Performance multi-function Low e Considerations Tempering Local Processing Air space Shipping Assuming an optimum air space for IGU comprising 6 – 16 – 6 more than 50% of your shipping cost will be for bringing air.

  14. Round Up • U values in GlassUnderstanding the calculation • Thermally Broken systemsSpending money on enhancing glass performance is offset by not giving consideration to edge effects • Gas filling Optimum performance • Ceramic Frit and Shading CoefficientsImprovements in Shading Coefficients and enhancing the appearance. • High Performance multi-function Low eWhere to process

  15. The Simple Approach to Energy Conservation • What makes this presentation a Simple Approach? • Understanding all the small steps that you can take to improve Energy Conservation in Glass lets you choose how far you want to go.
