>A Major Dairy
 
Space-Age Energy Saver
A controlled test was conducted on April 1-5,1988 by an independent engineer for a major dairy and poultry company to measure the effectiveness of Cerama-Tech as an energy saver. Cerama-Tech was applied to two separate areas on a galvanized metal warehouse. The warehouse, which was refrigerated to keep a constant 40 degrees on the interior, had the best insulation available on the market today for a refrigerated building.
 
The Test
Conducted on a 90 ft. x 200 ft. refrigerated building, and using one exterior wall, half was painted with Cerama-Tech and the other was not (approximately 50 ft. ea.). The wall was made of 20 gauge galvanized metal with 4 inches of frayed polyurethane foam insulation with a R31.2 rating. Large thermometers were set into the wall 3 inches deep from the inside to about 1 inch away from the interior wall. The thermometers were placed 10 feet apart, two in the Cerama-Tech portion and two in the non-Cerama-Tech portion.

During the test, the Cerama-Tech thermometers were 38 degrees to 53 degrees cooler than the non-Cerama-Tech portion with on average of 36 degrees difference on one pair to a 46 degrees difference on the other pair. The difference in the two measurements is attributed to the reflectivity of the radiant heat on the Cerama-Tech painted portion of the building.

The second part of the test was done on a portion of the high flat roof. A 15 ft. x 15 ft. section was painted with Cerama-Tech and a thermometer was inserted 5.5 inches into the 8 inches of frayed polyurethane foam insulation in the roof section. A section of roof without Cerama-Tech some 50 feet away was used to insert the second thermometer 5.5 inches into the some insulation. There was on average of 36 degrees F difference in the readings of the two thermometers, the Cerama-Tech one being the lower of the readings.

 
The Results
The engineer calculated that with only a 30 degree difference (not 38 to 53 degrees) that the BTU's per square foot would drop from 3.6 BTU's to 1.8 BTU's or in half, that would result In a 50% savings on what it normally costs to keep the building at the constant 40 degree temperature. In this case, the savings for the company would be $6,000 to $8,000 a month by having Cerama-Tech on the building.
 
Conclusion
Most buildings do not have the super insulation that the test building had and it would be quite easy to assume that with less insulation the higher the interior heat would be. We also have to take into consideration that the test was conducted using very pleasant spring weather and the temperature did not go over 80 F. The higher the outside temperature, the more intense the radiant heat would be resulting In a wider margin of difference between the Cerama-Tech section and the non-Cerama-Tech section. Most of us don't cool our houses or buildings to 40 F, but we would be safe to assume we would like it in the mid-70's. It's easy to see what a difference there would be in one's energy bill by having Cerama-Tech applied to the exterior of any building.
