The 4th of July is the time when we celebrate our nation -- a time to reflect on the freedoms which we believe are not granted by our government, but are self-evident rights for all humankind.
Time for the Independence Day Quiz which asks, "How much do you really know?" Every day thousands leave their homelands to settle here in the land of the free.
Before they become citizens they are required to take a citizenship test and score 80%. Could you pass this test if you took it today?
Our quiz is made up of 30 questions, of which 20 were once used on the actual citizenship test. We've added a few curveballs (10 additional questions), but a score of 24 out of 30 is considered a passing grade.
"In order to pull in enough outside air to cool the house at night, the NightBreeze requires a large exterior intake grille — usually about 3’x3’ (assuming the grille has 50% free area). If the air handler is located in the attic, the air intake grille can be mounted in a gable, in a doghouse dormer, or at the top of a false chimney. The air-intake duct is connected to a damper box containing a large hinged motorized damper blade. Damper leakage is minimal — at 25 Pascals, it’s about % of total fan flow. According to David Springer, the president of Davis Energy Group, one of the main consulting groups that developed the NightBreeze, ‘It is possible to achieve 6 percent duct leakage in a system that includes the damper.’ The wall-mounted NightBreeze control replaces a conventional thermostat. ‘At my house, the control is set for a 5-degree delta T,’ says Springer. ‘The upstairs thermostat is set to 80°, so it’ll start ventilating when the outdoor temperature drops to 75°. By morning, the outdoor temperature might be in the fifties or low sixties, and the indoor temperature might be 68°.’
