4 Introduction Heat Glass and solar control

5 Introduction Glass and solar control

6 Introduction – Solar radiancy
Intensity (W/m²) Energy 1.5 UV Light Short I.R. 1.0 0.5 780 2500 Wavelength (nm) Glass and solar control

7 Introduction – Solar radiancy
Solar spectrum : UV : 280 to 380 nm  5% energy Light : 380 to 780 nm  50% energy Short I.R. : 780 to 2500 nm  45% energy Glass and solar control

8 Introduction Solar radiancy Radiators Close IR Radio waves Long IR
Visible Long IR

9 Introduction – Greenhouse effect
1. Solar radiancy : UV, visual, short IR 2. Absorption: heating of the objects 3. The objects irradiate heat (long IR) 4. The glass is opaque with long IR = Greenhouse effect Glass and solar control

Introduction Solar and light factors Solar control glazings Planibel coloured Pyrolytic coated glass Stopsol Sunergy Magnetron coated glass Planibel Energy N/NT Stopray Synthesis Comments

11 The light factors (from 380 to 780 nm)
Lights factors tv = LT = transmitted light incident light 0,10 0,90 1 SG clear Light LT tv LR rv Glass and solar control

12 The light factors (from 380 to 780 nm)
rv = LR = light reflexion tv = LT = light transmission Glass and solar control

13 The energy factors (from 280 to 2500 nm)
Energetic factors 0,08 0,87 0, ,02 0,85 1 SG clear SF = g = transmitted heat incident heat Heat EAae DET te }g ER re qi qe Glass and solar control

14 Energy equation: DET + EA + ER = 100 %
The energy factors (from 280 to 2500 nm) re = ER = energy reflexion te = DET = direct energy transmission ae = EA = energy absorption g = SF = solar factor = total energy transmission Energy equation: DET + EA + ER = 100 % Glass and solar control

15 The energy factors (from 280 to 2500 nm)
Remarks : american index SHGC (solar heat gain coeeficient) = FS SC (shading coefficient) = FS/87 SC sw = TED/87 SC lw = SC – SC sw RHG (Relative Heat Gain) = 630 SC U

16 Light and energy factors - Selectivity
LIGHT = SOLAR ENERGY (50 %) LT = 80  SF = 40 at least SF = 25  LT = 50 at the maximum SELECTIVITY = LT <= 2 SF Glass and solar control
