The RCC Classroom (Radiant Control Coatings)

A group where energy professionals can learn about all the different energy saving aspects of RCCs.  I have worked with one particular RCC for 30 years.  I have amassed alot of information I can share.  Everyone knows, accepts and understands how RCCs work as a 'Cool Roof' coating.  However, that seems to be where the knowledge on these products different energy saving applications abruptly stops.  I hope to change that with this group. There are over 300 protective coatings out there and they…See More

Bud Poll replied to Hal Skinner's discussion How much heat energy is lost through the floor of a house?

How much heat energy is lost through the floor of a house?

I am asking this as I do not recall anyone speaking of any study to this end.  Many comments about adding insulation under a house with a crawl space and the benefits of doing that.  I do not recall hearing of any study or before and after type of readings.Heat travels towards cold and radiant heat travels in every direction, including straight down.  There is great amounts of discussion on the heat loss through walls and ceilings with lots of facts and figures. I dont recall seeing any type of…See More

Tom Mallard replied to Hal Skinner's discussion How our ceramic based RCC works in the group Radiant Control Coatings
"So it seems that what you're saying is for heat-transfer the stuff has little resistance or R-factor in conduction but "reflects" by wavelength perhaps so makes overall transfer much less than what the tests for R-factor expose. My…"

New Energy Star requirements for Cool Roof coatings

I was forwarded an email that originated from the Energy Star Heat Island group.  This was something I was not aware of.  I have changed the font to red for the main point of my own comments below the quoted part of the email.

 

"This call will provide an overview of the revised requirements for ENERGY STAR labeling of roofing products. The focus will be on the certification and verification processes. Beginning January 2011, labeling requires third- party…
