LEFT: Simplicity of quonset arch construction can be easily tollowed through these progressive views. From the pouring oi the concrete toundations and floor slab through the arches and purlins a simple box scattold is the key.

Excavation was required only for the auditorium floor grade, which over a length of 52 feet amounts to 41 inches. The Quonset section, entrance area and auxiliary space, including the projection room, rest on concrete footings, and all joists and door slabs are concrete. The main theme throughout the building shell and housing structures is one of economy.

Temperature Control

Economy, however, did not become a fetish or deprive the cash customers of any of the features they have learned to associate with the best houses. Inside the theatre, Hefferan provided ideal temperature control for twelve months of the yeareair conditioning in the hot and humid tropical days; radiant heating in winter weather.

Designed to maintain a consistent temperature of 70 degrees even during sub-zero weather outside, the radiant heating system, a gridiron of hot water pipes, lies buried in the concrete flooring of both the ground level and the second level above the front traffic and toilet area; andethis is a particularly valuable advantage in any small hall occupies no space within the auditorium proper.

The pipes are laid out so that the colder areas near doors and windows and outside walls, distribute more heat than the inner protected areas; and the entire system is spaced to produce an even temperature throughout the room. Most of the heat is distributed from the aisles, side walls and front and rear of the auditorium. Only sufficient pipe is located below the seating area to keep the floor warm without overheating the audience. The heating unit is an oil-fired steel hot water boiler.

While heating of the Crown is accomplished by the method described above, ventilating and cooling are provided by a duct system with re-circulation, and into this is introduced, at the mixing chamber, cooling coils which are supplied with cold water from a 480 foot well which also supplies water for drinking and for sanitation purposes. One supply duct extends down the middle of the auditorium ceiling above the Celotex ceiling and is equipped with Barber-Colman aspirating diffusers. The air-intake is above the screen platform, where Reynolds double-width, double-inlet blower is mounted along with filters.

Because of the different quantitative heatlizg requirements of the main auditorium and the other rooms in the Crown, .two zones were established, each controlled by separate thermostatsi Zone No. 1 serving the main auditorium and Zone No. 2 heating the remainder of the rooms. An outside thermostat coupled with a high-limit inside thermostat prcvonts unnecessary waste of heat. The radiant heating system was engi

RIGHT: The two-story front and entrance area. including the projection booth. is a separate structure built oi haydite block with metal casement windows and the marquee canopy. Its progress from foundation to root is here recorded.
