1 Sustaining Technology! The only constant aspect of Technology is,.change! -- Anonymous Sustaining Technology in Glazing Long way since 4000 BC, Today, Glass is no more a window element, but is an effective catalyst of Change in the construction Industry. MATERIAL Let s see how Glass plays a major role in modern day's technological advancements through three perspectives : Material Design Systems D M G S Did you Know??? Glass is 100% recyclable and we use broken glass for manufacturing 1

2 Sheet Glass Online Dynamic Clarity in Sustainability 4000 BC Glass Beads Float Glass Offline Modern Day Evolution of Sustainable Products Generation I Need : Aesthetics Online Coated ; CVD Coating Technology Advancement of Coating Technology Generation II Generation III Generation IV Generation V Need : Form & Function Metallic Oxide coating for Performance Debut of High Performance Magnetron Coated Product ; Need : Advanced Solar and Thermal Insulation in Single Glazing ; Nitride coating : For the Mass advantage Need : Rising awareness for Energy Conservation Evolution of Dual Advantage -Solar Control and Thermal Insulation Coating : Low-e Silver coated, DGU mandatory Need : Selectivity is the key. the need for the future.!! Advent of Double Silver Coated Products. The future is here!! Percentage of Solar Factor / Light Transmission Light Transmission SHGC Need: Super Selectivity & transgress towards extreme climatic condition.!! Generation VI With high light transmission and very low solar factor Online Coated Glass Offline Coated Glass Offline Single Offline double Offline Triple 2

3 Towards, Selective Growth! Spectral Selectivity 1 2 Sense and Sustainability Online Coated Offline Coated Offline Single Offline double Offline Triple Glass Glass Dynamic Exterior Facade Illuminating Glass Self sustaining Sustainability Solar & glare control regulated to exterior climatic conditions Intelligent Sustainable reflexes to safeguard internal environment Intelligent façade, minimal human intervention Climate responsive Reduction in Operating costs Improved thermal comfort & elimination of visual glare Light Emitting Glass, Dual function of structural stability and dynamic functionality eco-illumination Increased Lighting efficiency Take Green light forward Reduced electricity consumption Increased light penetration High colour rendering Close to natural lighting 3

4 Photovoltaic Facade Façade as an Electricity source On roof As roof Vertical walls Glass as a vital component of Energy Generation Energy Conservation Giant leap towards Self sustaining Net Zero Buildings Reduced dependency on conventional sources of energy Dual material advantage of Energy Generation and conservation DESIGN Daylight Analysis Building Orientation Sun Path Analysis Site Shadow Analysis Shading and Overhang Analysis 4000 BC Glass Beads Transparency Reflective Glass Aesthetic preference Advent of Energy codes Need for high performance glass Dynamic Façade Climate responsive Thermal Analysis 4

5 Building Orientation Analysis Did you Know??? You can save upto 20% of Energy, just by Intelligently Orienting your building!! Annual / Monthly sun movement Understanding of critical elevations of building Better understanding of solar altitude & azimuth Sun Path Analysis Optimised façade performance Best fit Glass solution for each direction Judicious spend on Glass Building Envelope - Solar Exposure Shading and Overhang Analysis Influence of surrounding buildings or obstacles Shadow Range Analysis of solar incidence to calculate relative heat gain Monthly / hourly analysis Calculate Natural Shading for the facade Best fit Glass solution for each direction Judicious spend on Glass Window Shading Overhang depth Impacts Prescriptive requirement of ECBC Effective SHGC requirement For Green Building Compliance Reduces incidence of Solar heat Optimizes Light penetration Arrive a an apt shading mechanism Overhangs Vertical fins Louvers 5

6 Daylight Analysis VLT Daylight Analysis Green Building compliance Did you Know??? Sunlight has 1/5 th of the Light and Heat ratio compared to an energy efficient lighting system!! Eliminating artificial lights during daytime operation Minimizing glare due to excessive light Reduction of Lighting Energy by 20% Percentage penetration of Light into the floor space Calculation of Heat Transfer through envelope Cooling Design Estimation of Electricity consumption Thermal Analysis Minimising Cooling Needs Capital expenditure in sync with cooling design Operational Costs controllability Glass design,considering Wind load Analysis on the Processing requirements of the glass Finite Element Analysis,for deflection and stress check Structural Design optimum thickness of Glass combination Helps arrive at an appropriate glass processing Toughening, Lamination) Arrive at a Cusp of More Safe Less cost vantage point 6

7 Ceramic Frit Unlimited Design Possibilities Optimisationof Light Transmission for Green compliance Controlled Reduction in Solar Heat gain Add a dash of life to your Green facade Allows diffused daylight and minimisesglare effect Reduces Cooling requirement Did you Know??? SYSTEMS Façade is 8 times lighter than conventional brick wall Design Drivers of a System 4000 BC Glass Beads Glass for Window Structural Glazed system Unitized / Semi Unitized system Frameless facade Reduction of Infiltration through Fenestration Air, water & sound infiltration between glass and frame View: Large panel Sizes improves the un restricted outdoor view & reduces the usage of Aluminium usage Increase in panel size by about 50% reduces the fenestration by over 5 kg Energy: Thermally broken Aluminium frame to minimize heat transfer Reduce Heat gain due to better insulation Air leakage through fenestration & doors shall not exceed 2.0L/s-m2 Innovative fabrication of façade through Unitized, Semi unitized & Frameless façade Thermally broken frame reduces U value by over 20% 7

8 Human Safety SAFETY Glass For Safety Against injury & people fallingthroughglass Against glass falling Glass For Security Overhead Glazing Vandalism and burglary Fire-arm / Explosion & bullet You need to be SAFE to Sustain Sustainability!! Functional Requirement Fire Safe Glass MATERIAL E Class Criteria: Integrity EW Class Criteria:Radiation EI Class Criteria: Insulation G SAFETY Glazing products to block smoke, flames & toxic gas. Resistance Time mins Products to reduce radiant Products providing a barrier heat transfer (limit 15 to radiant and conducted KW/ sqm at 1m distance) heat transfer (140 C) DESIGN SYSTEMS 8
