The above image is of a cold roof that had very poor insulation installed and moisture damage due to condensation problems.
This ceiling fan was turned off for about 5 minutes prior to this image. This is showing the heat from the motor. Ceiling fans do not help cool the house, they only cool a person when under the fan. Turning ceiling fans off when you are not in the room is a sure way to save electricity.
Air leakage in a brand new house that was spray foamed. This is not uncommon, even in good installs, as this is simple to occur. Having a thermal image prior to insulation being finalized can help identify weak points in the envelope prior to these problems initiating a call back, which many times is due to condensation problems and possible mold and mildew related issues.
This is another example of a very nice home by a superb contractor, but the spray foam and air sealing job was not complete. This home actually earned a Green Building Certificate, and problems are still occurring. It pays to test, but to also test properly with the proper diagnostic tools, and at the proper times.
Air leakage along baseboard and around phone jack. Too much attention cannot be paid toward air sealing. During new construction or an extensive remodel, your money and time will be well spent and rewarded with proper use of caulk and foam.
Can lights are normally not airtight and can be a large source of air leakage. Replacing incandescents with CFL's help with heat gain from the lights, but the hot air from outside can cause condensation problems and a higher-than-needed electric bills.
This image is of plywood drop soffits for HVAC duct work under a beachfront house. There was significant duct leakage and enormous amounts of mold and mildew growing on the plywood's interior surface. Proper sealing and taping of the ductwork will increase the comfort and indoor air quality in your home or business. |
