    1. Technology & World Change Photochromic Retractable Shades

    2. Background Info – Photochromic Technology Photochromic dyes changes colour upon exposure to sunlight or UV rays Due to alteration in molecular structure Dyes are not reactive in powdered form Have to be dissolved in appropriate solvents to work Already in use in Transitions Lenses

    3. Introduction Companies face pressure to develop environmental-conscious products PRS makes use of sunlight and does not require electricity to work PRS provides protection from UV rays and shading from the sun Can be mounted above existing windows

    4. Photochromic Retractable Shades Using technology from Transition Lenses Reapplication of tech in PRS PRS provides protection from UV rays and shading from the sun Can be mounted above existing windows

    5. Basics

    6. Basics Roller 3 sheets with Photochromic films 1 sheet reflective/opaque No electricity required Mounted above windows Constraint

    7. Functions and Specifications Four-layered Roller Device manually controlled and rolls out the film shade as specified by user military specification metallic tubing Differing lengths and choice of 3 colours DIY attachment Chain Control Mechanism similar the ones used to operate blinds used to switch between the different film shades manually controlled and energy efficient

    8. Functions and Specifications Photochromic Film natural reaction to and automatic dimming of sunlight Photochromic dyes dissolved in plastic films Each layer have differing thicknesses and shading intensity variety of colours and shades available Coloured Film provide privacy when little or no sunlight available metalized coloured films e.g. gold, bronze and cool gray block out 79% heat and 89% UV rays scratch resistant coating All films will overlap window dimension by at least 2 inches for optimal performance and minimize light leakage

    9. Cost Relatively high in conception stages Realistic expectations of cost effectiveness and cost reductions over time Roughly estimated to priced from SGD 130 to 200 Estimated mark-up of 30 to 40% over current blind systems available Due to suitability of PC dyes with plastic, only small concentrations of PC dyes is needed for the films

    10. Competing Technologies Suspended Particle Devices technology (SPD) Liquid Crystal technology (LC) Electrochromic technology (EC) Used mainly in application of Smart Windows.

    11. Suspended Particle Devices 2 panes of glass separated by a thin film with suspended, light absorbing, microscopic particles When no voltage is applied, particles absorb light ? window is opaque When voltage is applied, particles align and allow light to pass thru’ film ? window is transparent Control amount of light passing through the window by varying electrical voltage

    12. Liquid Crystal Similar to SPD Difference is that window can only turn transparent or opaque; no intermediate settings Used in LRT trains to protect privacy of HDB residents

    13. Electrochromic Also similar to SPD, but reacts in reverse to electricity Window is transparent when no voltage is applied

    14. Competitive advantages Photochromic technology does not require electricity ? cost & energy efficient Photochromic dyes are available in many different colours and shades ? greater aesthetic appeal PRS can be fitted onto existing windows ? low cost of product adoption

    15. Business Model Initial Stage Advantage of convenience Sale of idea to existing window makers

    16. Business Model Entry Into Market Collaboration with real estate developers In newly constructed apartments Instill product image in consumers Barrier of entry to potential competitors

    17. Business Model Brand Marketing Advertising Become the ‘Standard’ of shades and curtains market Sales to individual households

    18. Business Model Product Sustainability Royalties Future of PRS

    19. Impacts Reducing lighting and air-conditioning costs for homes or offices and--reducing glare. Reduction of 30-40% of energy used in office buildings -> Saving millions of dollars nation wide annualy

    20. Impacts This opens up to a new dimension of art and industrial design . changing of film (intensity and color) can be done easily, it makes the product of extremely reusable and replaceable.

    21. Impacts Price is low enough for mass consumers It is predicted that these shades have the potential to capture 25% of the market for offices and commercial buildings.
