Real World Ceiling Fan CFM

Has anybody done testing on delivered CFM of ceiling fans? Energy star has a test room where the blades are 40 5/8" from the ceiling, but this rarely happens in living rooms. Perhaps manufacturers should list actual CFM output at various mounting heights instead of the laboratory 40 5/8" that almost never exists in the real world.How is CFM affected when installed at the default 12" from the ceiling? When used with taller ceilings, does installing a 12", 18", or even a 24" downrod significantly…See More

Bob Blanchette replied to Energy Wise Solutions's discussion No Utility Homes, Are we ready to start building Homes that are not connected to traditional utilities ?
"Utilities are starting to "catch on" to the "green movement" and are increasing the fixed monthly connection charge instead of KWH rates. Disconnecting completely is the only way to eliminate this ever increasing fixed cost."

Replaced my A/C this weekend, results of downsizing by 1/3.

Posted on September 2, 2012 at 4:39pm 2 Comments

Recently my 13 yr old Carrier A/C devolved a leak and I chose to replace the system rather than track down the leak and repair the coil. I had been reading about doing manual J calculations and how contractors are scared to death to undersize. I had been talking to co-workers about this and it's an uphill battle getting them to think different than 1 ton per 500sq ft. So I decided to take confidence in correct sizing and "put my money where my mouth is" and install a 2 ton sized…

How SmartHours Plus works: It costs more for electricity during peak periods of high customer demand.

Other factors, like weather conditions and the time of year, also drive electrical prices higher. SmartHours Plus,

sometimes known as Variable Peak Pricing (VPP), allows you to save when costs are lower, or off peak. Peak hours

are 2 to 7 p.m. weekdays, and prices during those hours vary based on demand (see chart). You’ll get advance

notice of tomorrow’s peak price the…
