Note: The SunAngle program currently uses a more sophisticated algorithm for EOT calculations, but the above formula is a decent approximation and much simpler. SUSTAINABLE BY DESIGN :: TIME BASIS LSTM = The local standard time meridian, measured in degrees, which runs through the center of each time zone. It can be calculated by multiplying the differences in hours from Greenwich Mean Time by 15 degrees per hour. Positive = East, and negative = West. Note that if the site is east of the LSTM, the (LL - LSTM) factor should be apositive
SUSTAINABLE BY DESIGN :: ELEVATION Sustainable By Design :: Elevation. This input is your elevation compared to the surrounding terrain, in meters or feet (use the pull-down menu after the input field to indicate which one). This is not necessarily the same as your elevation above sea level; it's your height above (or below) the land and geographical features in yourvicinity.
SUSTAINABLE BY DESIGN :: SUNRISE / SUNSET Sustainable By Design :: Sunrise / Sunset. The times of sunrise and sunset are calculated as the times of morning and evening that the sun is apparently at the horizon. In the outputs section of SunAngle, sunrise and sunset times are given in clock time. The sun would normally appear to be exactly on the horizon when its altitude angleis zero
SUSTAINABLE BY DESIGN :: LATITUDE & LONGITUDE Sustainable By Design :: Latitude & Longitude. These inputs describe the location for which sun angles will be calculated. Both values are measured in degrees, and pull-down menus are used to indicate north/south for latitude or east/west for longitude.

SUSTAINABLE BY DESIGN :: INSTRUCTIONS You should enter as much information as possible into the Inputs section, then click on the Calculate button. The calculation results will then appear in the Outputs section. SUSTAINABLE BY DESIGN :: INSTRUCTIONS How to use the program. The general question addressed by Overhang Annual Analysis is: To what extent is a window shaded by an overhang each hour of the day during each month of the year? With this information, an architect, designer, builder, or home owner can design a window system that admits sunlight when it is desirable, and provides shade when it is not. SUSTAINABLE BY DESIGN :: LATITUDE & LONGITUDE These inputs describe the location for which sun angles will be calculated. Both values are measured in degrees, and pull-down menus are used to indicate north/south for latitude or east/west forlongitude.

The altitude angle is negative when the sun drops SUSTAINABLE BY DESIGN :: INSTRUCTIONS The sunshine value is the fraction of possible sunshine that reaches the ground during a month, expressed as a percentage (clouds and other atmospheric phenomena reduce the amount of incident sunshine).
