The total laboratory is approximately 12,000 square feet in size. The laboratory first opened for business in Houston in March, 1982. Since that time we have performed testing on projects around the world. There is no other laboratory that has the testing experience we do in our areas of interest.

The reverberation room is 14,500 cubic feet in size. The room and equipment meets ANSI S12.51 for determination of sound power levels of noise sources using sound pressure in reverberation rooms. All of our sound instrumentation is Bruel & Kjaer.

The mockup room is 2160 cubic feet in size. The room is equipped with a raised floor for underfloor terminal unit and diffuser testing. The ceiling is located 9 feet above the 1 foot raised floor system and there is a 36 inch ceiling plenum depth. All of the plenum space walls can be opened or closed to the main laboratory.

This is a 2 room assembly. The outside room that represents the space outside the building is 14 feet tall by 6 feet long by 20 feet wide. Seven and one half (7 1/2) tons of low temperature refrigeration is dedicated to service this space. The curtainwall opening can accommodate up to 20 linear feet of glass and mullions. The test room attached to this space is 20 feet wide by 24 feet long. Both the test room ceiling and the glass wall can be adjusted for a 12 foot height space. The floor is a 1 foot raised floor system.

This is a 3 room assembly. The center room is the mechanical room and is 25 feet by 16 feet in size and has a 12 foot deck height. Located on each end of the mechanical room are office spaces measuring 14 feet by 16 feet. The offices have a ceiling located at 9 feet off the floor.

The heart of the system are the Calmac ice storage tanks. Each tank has a total capacity of 190 ton hours. Forty tons of low temperature chillers provide the cooling to generate the ice. The ice is made and stored at night for use during the day.
