OK. I have been involved with an Energy Star 'Cool Roof' coating since it hit the market 25 years ago. This is way before Energy Star ever came around.
In 1988 I coated the roof of a refrigerated truck for a local ice company. After two weeks we got a verbal report back that it "Did really good and helped alot". Shortly afterwards, we did the entire fleet of 15 trucks.
A month after that we were informed they were averaging a 7 gallon drop in fuel used by the refer units on their normal 4 or 5 day routes. Then we were informed that they were losing the bottom 2 layers of bagged ice on each pallet in most of their trucks and now they were losing none.
A year later we coated the top of an ice cream truck and they got a 10 gallon a week reduction for a 5 day normal route.
Then our manufacturer told us to stop wasting our time as these jobs were too small and did not sell much coating. So, as far as I know, no more trailers were coated after 1989. We are now starting to do some again in Texas.
I contacted one of the EPA's labs in Texas and proposed a test for them along these lines. Protect the product in the trailer, reduce the heat load on the unit, extend the life of the unit, reduce fuel consumption and associated exhaust emissions too by putting an Energy Star Cool Roof coating on a refrigerated trailer.
They researched this and said it makes a lot of sense. However, they have absolutely no format or protocol to do such a test and have it verified by a third party.
We have only had the 'Before' fuel records for the units that are maintained by the trucking companies and their individual route drivers. We know what they used prior to the applications, then we see what the 'After' results are, again, by the same fuel records kept by the companies and their drivers.
Anyone have any experience or recommendations for this, other than what we already have for before and after stats? I do not know of any other means than the 'Before' and 'After' stats I have already mentioned.
How many refrigerated trailers are running around and how much less exhaust emissions are we talking about?? I have no clue but it would be a very substantial amount.
