All principal components are manufactured from extruded aluminium alloy type 6063 T6 with stainless steel fixings.
The fins may be fixed at any angle and can rotate under motorised control. The GLASSCON solar shading system comprises a series of extruded aluminium fins mounted into a support frame. A variety of blade control options include: manual by friction, mechanical or electrical remote control. Properly engineered, these structures can resist wind loads of up to 150 km/h. The frame and blades are made of powder-coated or anodized aluminum.
GLASSCON metal blinds/louvers and airfoil louvers are available in a variety of colours. It may also be combined with other GLASSCON products such as roof lights and glazed facades.
I thank in advance everybody that has time and willing to reply.GLASSCON metal louver shading systems and airfoil solar blinds is a fixed or controllable external aluminum solar shading system that may be installed either vertically or horizontally in front of the façade. Of course, to compute a sundial is required a greater precision than the precision required for a simple buildings solar illumination study. The current discrepancy, I believe, are mainly due to the greater precision of my algorithm with respect the AutoCad one. If I could know the algorithm used by AutoCad I could to adapt my sundials calculator algorithm in a such way to get perfect simulations. Which other astronomical parameters are considered by AutoCad in order of improve the accuracy? How AutoCad takes into account of the equation of time and of the seasonal sun declination? Does somebody know how AutoCad computes the elevation and azimuth angles? Does somebody know whether and how it's possible to use more decimal digits to define the latitude and the longitude? I have also noticed that to define the longitude and the latitude are used only three digits after the decimal point. These discrepancies, very likely, are due to an insufficient precision of the algorithm used to compute the elevation and azimuth angles inside AutoCad. In some preliminary experiment I have noticed some slight discrepanncy between the position of the shadow casted by the virtual sun of AutoCad and the theoretical position indicated by my computations (of which correctness I'm sure because proven in the field). To design my sundial I will use AutoCad so I can see how it appears when illuminated by the virtual sun (command _lights Sun Angle Calculator) and rendering. a clock working through the sun casting a shadow).
I'm an italian professionist and I'm going to design a sundial (i.e.
