The following information was obtained from an article in Insulation Outlook, written by Christopher P. Crall, published January 2009.
Insulating a bare surface can easily reduce heat losses or heat gains by 90–95%, and the need to conserve energy is obviously increasing.
Insulation has long been recognized as a LOW COST method of conserving natural resources. What is not well known is that insulation is considered one of the best sustainable technologies available. In fact, insulation can be considered effectively “greener than trees.”
As an example, consider a chemical facility that uses steam at 350°F in a manufacturing process that operates year round. The steam produced in an oil-fired boiler operating at an average efficiency of 80%. The cost of purchased fuel oil is $4/gallon. The 4-inch steam header is outdoors and insulated with 2 inches of fiberglass pipe insulation. The calculations in the following table were made using the 3E Plus® computer program developed by the North American Insulation Manufacturers Association (NAIMA).
BARE 4" PIPE --> Heat Loss in Btu/h/ft = 1,460; Annual Fuel Cost, $/ft/yr = 438;
Carbon Dioxide, lbs/ft/yr = 2,427
PIPE INSULATED WITH 2" FIBERGLASS --> Heat Loss in Btu/h/ft = 71; Annual Fuel Cost, $/ft/yr = 21; Carbon Dioxide, lbs/ft/yr = 118
$AVINGS --> Heat Loss in Btu/h/ft = 1,389; Annual Fuel Cost $/ft/yr = 417; Carbon Dioxide, lbs/ft/yr = 2,308
The use of the insulation has reduced heat loss from the bare pipe, on average, by 95%. The associated fuel cost has decreased by 95% for a fuel-cost savings of $417 per foot per year. This 95% reduction in fuel usage translates to a 95% reduction in CO2 emissions, a savings of 2,308 lbs. of CO2 per year!!!!
Trees are a very important part of the carbon cycle. Trees use photosynthesis to remove and store carbon from the atmosphere. So, how much CO2 is absorbed from a tree? It varies with the type of tree, its location, and its stage in the life cycle. An average derived from many sources will allow us to assume that one tree can absorb a “rough estimate” of 50 pounds of CO2 per year.
With this in mind, one would need to plant roughly 46 trees to achieve the same CO2 regulations achievable by insulation of 1 foot of 350°F pipe!!!!
