Solar Heat

Most of us are familiar with the socalled solar house, but the principles of solar heat have not yet been applied to commercial buildings on a large scale. While it is doubtful the sun could provide much auxiliary heat for theatres as they are presently being constructed, there may be cases where, with proper orientation, use of large areas of insulating glass on the south side and proper roof overhang, a theatre owner could take advantage of the suns heat during winter months.

In order for the sun to supply this heat it is first necessary to have the building properly oriented in respect to the compass. In other words the open side, where the large glass areas are used, should face south to catch the warm sun rays during the winter months. This south side would have to have free access for a considerable distance

so that the low-hanging winter sun would not be blocked from shining into the building. Overhangs should be provided so that the unwanted summer sun, which is higher in the sky, would not shine into the building. Glass areas should be of the double-paned, self-insulating type so that solar heat would be Wrapped" inside the building and would not immediately escape back through the glass areas.

If these conditions were possible in a theatre, solar heat could be a factor in supplementing the heating plant in cold weather. Doors of the theatre are generally being opened and closed for a relatively brief period,' during show hours-wand should not be a serious hindrance to solar heat gain. Factors such as geographical location, directional orientation, wind velocities, shading by nearby buildings, and the type of heating, ventilating and air conditioning system will all affect the degree to which solar heat is beneficial. The problem can best be handled by a competent architect who is familiar with the solar heat factors in his locality.

Large glass areas facing south which admit full sunlight (hiring cold weather can help warm the theatre lobbies and entrance-ways. Certainly, theatres whose fronts are predominantly of masonry or some opaque material would not have as much help from the sun.

A still more important problem for most theatre owners Would be to retain heat, whether from the sun or from other sources, once it is distributed

throughout the building. Again, it should be remembered that single glass, particularly window or sheet glass, is a major "leak" for interior heat. Wherever possible these glass areas should be insulated, preferably by using a double-glass unit or storm sash. In that way a large amount of heat that would otherwise escape through the glass will be retained inside the building.

To sum up, the thermal value of glass to the theatre owner, and the possibility of solar heat through the use of glass would be individual to each theatre and, therefore, no general rule can apply. As noted, the variables encountered in the problem are geographical location, orientation to north, east, south or west; wind velocities; shading by a marquee or tall building on the opposite side of the street; fluctuation of the residual thermal heat within the structure itself; variation in lighting made in the lobby; variation in number of standees; roof exposure; type of heating, ventilating or air conditioning system used and operating hours in the day during which the theatre is open.

These, then, are a few of the possible applications of glass and glass products to the modern theatre. Many other uses will suggest themselves to the experienced theatreman, his architect and decorator. But this much is certain: glass will continue to be used to a greater and greater extent not only for its functional and decorative qualities but because of its constant availability through all and every emergency and condition of business. The effects that can be obtained by properly utilizing its great variety of developments are limited only by the imagination of the individual designer. It is without doubt the most adaptable of all present day structural materials and can be made to harmonize with architecture of any type. Its judicial use can spell the difference between a run-of-mill barely acceptable theatre and one that will continue to be modern and sparklineg up-to-date through many years to come. Dramatic and impelling glass promises much for the future of modern design in both new and refurbished theatres.
