Architecture Professor's Invention To Be Shown At Engineer's Exposition
By CLARK AKERS
The inside-outside heliodon to be exhibited at the annual Engineering Exposition enables architects to study the effects of sunlight on buildings from dawn to dusk at any latitude.
The inside-outside heliodon, so named because it shows the sun on both the inside and outside of building models, was developed by George M. Beal, professor of architecture.
A model of a proposed building is placed on the table of the heliodon. Then a light which represents the sun is passed over the model exactly as the sun passes over actual houses. This enables the architect to see what his proposed house will look like at different times of the day.
Professor Beal says that by using the inside-outside heliodon the architect can analyze the angle, character, and quality of the sunlight and design his buildings to give a
Through a mirror placed under the model, the architect is able to see exactly how the interior of his building will look in actual sunlight.
brighter interior with a minimum of glare and other bothersome qualities of light.
The heliodon is valuable to those interested in the therapeutic aspects of light. It aids in designing hospitals, classrooms, factories, and homes which will admit as much light as possible with a minimum of eyestrain to those inside.
Many modern houses are designed to harness the sun's rays for heating purposes. Professor Beal's heliodon helps the architect to orient his building in relation to the heat of the sun.
The inside-outside heliodon was developed by Professor Beal in 1939, and was used during the second world war by students and military men to study camouflage techniques.
