Solar Sun Chart Shading Calculation Line up the device with true south ( Rotate to 13° West of magnetic South) Locate points from east to west Measure altitude angle and azimuth angle for each points. Plot the value on the sun chart Sun chart for any particular location can be calculated and printed out University of Oregon’s website: http://solardat.uoregon.edu/SunChartProgram.html

Solar Passive Solar Design USE OF SUN SPACE: In Winter, the opening of external skin is shut and both of the internal windows are opened. When sun heat the sunspace, the hot air rise and flow into the interior through the opening at top pulling the cold air from the opening at the bottom. In Summer, the opening of the external skin and bottom opening of internal skin is opened. The hot air in sun space rise and escape from the opening which pulls the cool air from other side of room

Solar Shading Shading Technique

Wind & Geothermal Aerodynamic principle Aerodynamic shape of the wings Aeroplane creates the pressure difference due to varying speed in upper and lower part of the wings which makes it possible for aeroplane to lift in the air. Using same principle along with the prevailing wind, if we put the wing in the stationary position, the pressure difference might be utilized for the air flow inside the building. If the curent of the wind is strong enough it might be even possible to use it in combination with Earth air Tunnenling system to minimize the energy of the fan.
