 Results of the Cotton Electric Coop Energy Audit -- September 3, 2009

  • The gaping hole between the meeting room and the attic is a huge energy waster, both in summer and in winter. The hole should be immediately covered with plastic while awaiting a more permanent closure. A well sealed and insulated door over the attic opening could cut air handling costs in half.
  • Consideration should be given to installing a people entrance (for filter change, inspection, and minor maintenance) into the attic other than the opening between the attic and the meeting room, leaving the large entrance sealed with an insulated door except when needed for equipment exchange. A small opening, drop-down stairs, possibly in the men's restroom shower/storage room (See the attachment for an example of this type stairs.... one like it is available at our local Lowe's.)  
  • The attic wall of the equipment room is not insulated at all. A large amount of heat exchange is taking place through the wallboard all across that wall. High R-value sheets of insulation foam should be installed directly to the attic-side wall. The attic area at the other end of the building should be inspected to ensure that the wall is insulated.
  • Install filters in the air handlers as soon as possible. While not an energy-usage problem, the service life of the fans and motors is adversely affected by running the systems without filters. The size is 20x25 inches. The filters are housed in the air handler in the attic.
  • The insulation in the attic is not uniformly thick. Now that all equipment has been installed and electrical and hood work is completed, traffic in the attic will be minimum. Additional insulation should be blown in soon to make sure thin spots are built up.
  • (Observation) The newly installed restroom fans are not properly vented to the outside. The air ducts used by the replaced smaller fans lie unused nearby. The exhaust of the new fans should be connected to the old ducting.
  • (Observation) Drain vents that correctly terminate in the attic (from the restroom lavatory drains) still have the coverings that were to have been removed when the lavatories were placed into use. They should be removed for proper operation of those drains.
