5 Greške vezane za dimenzije maksimalne dimenzije Težina stakla Troslojno staklo primjeniti (ne) primjenii Optičke deformmacije i refleksija

6 Dimenzije maksimalne dimenzije stakla 321x600 cm Dostupne debljine (ovisno o vrsti stakla): 3,4,5,6,8,10,12,15,19, 25 mm, najčešće 4,6,8,10 mm Mogućnost prerade: rezanje, posebni oblici, brušenje rubova, kaljenje, laminiranje

7

8 dimenzije Maksimalnedimenzije za: kaljenje, najčešće 240x420 cm lokalno laminiranje najčešće 200x380 cm Na zahtjev veća kaljenja stakla mogu biti isporučena, no trošak može biti značajan.

9 težina Gustoća stakla ρ =2500kg/m3 Npr. 4mm - 1 m2=> 10 kg 10 mm - 1 m2=> 25 kg IZO 4000x2000mm, kompozicija => 520 kg!! akvarij 2000x1000x1000 mm, kompozicija prazan (samo staklo) = 400 kg Bez vode (without metal structure!)= 2400 kg

10 Opterećenja vjetar, snijeg itd. Kalkulacija mora uzeti u obzir lokalne normative Specificne zahtjeve AGC može dati preporuke primjer

27 if possible, outside glass should be thicker than inside glass

28 Anisotropy leopard spots not really a mistake, but not so nice

29 solar control heat

31 solar control LT = light transmission, SF = Solar Factor Light 100 LR LT heat (DET) (ER) (EA) (SF) g Energie reradiata ext Energie reradiata int

32 green house effect 1. Energy : UV, light, shortir 2. absorption of heat 3. radiation of heat (long IR) 1 4. glass is blocking long IR green house effect = overheating of interior space

33 Što znači solarna kontrola Solarna kontrola = limitira prolaz topline kroz staklo kako bi se smanjio efekat staklenika. SF=20 45% Različita riješenja, bojena stakla ili stakla sa nanosom (pirolitički prmaz ili magnetron) itd..

34 Transmision % clear glass Selectivity= LT SF 0 Stopray (selective) wave lenght [nm]

35 Važnost solarne kontrole people are using different types of foils (sometimes from packages!) in order to stop the heat coming in the house

36 money, money, money.. Energy from Sun: 1000 W/ m2 (with normal clouds etc) Energy which is touching vertical window: 750 W. hypothesis: 100 m2 of windows or façade. Cost 1 kwh= 0.42 RON. HVAC working 30 days* 6 hours a day= total 180 hours SF= 0.64 ( clear glass + lowe) => Heat = 750*0.64= 480 Wh/ m2 of window. For 100 m2 facade, monthly => heat: 480x100x180= 8640 KWh. SF= 0.29 (Sunergy Green 6mm+ lowe) => Heat 750*0.29= 217,5 Wh/ m2 of window. For 100 m2 facade, monthly => heat: 217,5x100x180= 3915KW. Electricity COST if SF=0,64=>8640x0,42= 3628 RON= 863 EURO Electricity COST if SF=0,29=>3915x0,42= 1644 RON = 391 EURO For only 100 m2 of façade, monthly, there is a difference in cost of 472 Euro!! In only 3 months of summer, the slightly higher cost of Sunergy Green will be paid back! The smaller SF, the better, because cost of electricity will be smaller but also cost of HVAC (cooler or chiller) will be smaller. BUT DO NOT FORGET PLEASE about Light Transmission LT (or selectivity), otherwise better to replace windows with bricks and you will have SF= 0 (zero). CONCLUSION? Look for low Solar Factor SF, especially for South oriented facades, and search for highest selectivity (S=LT/SF). Stopray Lime= the best solution. Sunergy Green= very smart solution Planibel Green= very good solution for E, W and N facades
