"As far back as 1624... Louis Savot invented the first heat-circulating fireplace. His unit was installed in the Louvre, Paris, and became the prototype for Ben Franklin's 1742 Pennsylvania stove. The 1624 French fireplace achieved 30 to 45 percent more efficiency than do most American tract home fireplaces of today! Savot surrounded the grate of his creation with a metal chamber, which had warm air outlets above the fire opening. He also supplied the fire with air from under the floor. Thus, room drafts were reduced and combustion efficiency was further improved. Few people are aware that practically all of the technical features of Franklin's Pennsylvania stove were copied from earlier inventors."

“A perfectly flat roof permits up to 50 percent more heat gain that a pitched roof... This illustrates the failure of the flat-roof construction to get natural, hot air flow out from under the eaves.”

“Cooling systems... need only supply a drop of from 10 to 20 degrees below that of the outside temperature. ...greater cooling differentials... are a real injury to health.”

“It costs three to five times as much to remove a BTU of heat from a house in the summer as it does to add one BTU of heat in the winter.”

“Ceiling insulation is... preferable to roof-top insulation.”

“Trellises for leafy vines, which will lose their foilage in the fall, should be set up over southern windows so that sunlight will penetrate into the house through the winter months.”

“No critic as yet comprehends entirely why our houses are so poorly constructed, why they look so abominable, why they cost so much for construction and for maintenance, and why they are so uncomfortable.”
