:360 Condensation Control

Take the 1:5:10:365 challenge: Do one thing – for 5 to 10 minutes – 365 days a year to make our home and planet environment better.

1:5:10:360 EcoTip: Condensation on cold surfaces can be eliminated by reducing the humidity. Reducing the humidity lowers the dew point temperature. By lowering the dew point temperature below the temperature of the coldest surface condensation can be eliminated.

Suggested Review: :359

Humidity can be lowered by reducing the amount of moisture that is going into the air. Ventilating cooking, laundry and bathroom moisture to the outside can help. If moisture is entering the building from the outside – for example through a concrete slab or from outdoor elevated humidity, then dehumidification may be needed in the winter.

:359 Cold Surface Condensation

Take the 1:5:10:365 challenge: Do one thing – for 5 to 10 minutes – 365 days a year to make our home and planet environment better.

1:5:10:359 EcoTip: The dew point occurs when temperatures on a surface are cold enough to cause condensation to form. If this happens on the outside of a can of soda – its not such a big deal – but if it happens on or inside wall or building cavities – the condensed water can result in damage and mold growth.

***********************************

 Additional Information:

The blue area in the thermal image shown above is missing insulation. If the indoor temperature is 68 degrees F, and the humidity is 50% condensation will develop if the surface temperature hits approximately 50 degrees or less. The condensed moisture can result in water damage and mold growth.

:358 Microwave Oven Tester

Filed under: :358 Microwave Oven Tester — Tags: , , , , , , — John Banta @ 5:04 am

Take the 1:5:10:365 challenge: Do one thing – for 5 to 10 minutes – 365 days a year to make our home and planet environment better.

1:5:10:358 EcoTip: If you use a microwave oven, it is prudent to keep your distance and only use an oven that is properly operating. A number of microwave leak testers are available that can be used to provide a rough approximation of whether an oven is leaking or not.

***********************************

 Additional Information:

Suggested Review:

A Federal standard limits the amount of microwaves that can leak from a microwave oven. New ovens may not leak in excess of 1 mW cm–2at 5 cm and once placed in service may not leak microwave radiation in exceeding 5 mW cm–2 at 5 cm from the oven surface. The radiation level falls off quickly with distance, so staying 20 inches from an operating oven would reduce exposure 100 fold.

Interestingly enough – some European countries have safety standards that require workers wear safety goggles if exposed to microwave levels in excess of 1 mW cm–2 and some studies suggest that these low levels of radiation exposure can cause cataracts with cumulative exposure.

If your going to use them – it seems prudent to step away from the oven, and don’t let the kids watch the food cook.

:357 Air Washing

Filed under: :357 Air Washing — Tags: , , , , , — John Banta @ 5:03 am

Take the 1:5:10:365 challenge: Do one thing – for 5 to 10 minutes – 365 days a year to make our home and planet environment better.

1:5:10:357 EcoTip: Air washing occurs when air leak in the building envelope allow air to flow through insulation – reducing its effectiveness. Air washing can be diagnosed using thermal imaging or thermal leak detection in combination with creating a strong negative air pressure when the temperature difference between the inside and outside is at least 20 degrees F.

***********************************

 Additional Information:

Suggested Review: :113, :356

Performing the inspection without negative pressure (:356) helps evaluate the effectiveness of insulation when there is little or no wind or other pressure forces. Performing the inspection with a negative pressure simulates the way the building behaves when outdoor conditions are windy or there are other pressure forces present.

It is important not to cause back-drafting which can result in carbon monoxide poisoning or fire from flame roll-out when conducting negative pressure tests for air washing.

:356 Heat Loss Inspections

Filed under: :356 Heat Loss Inspections — Tags: , , , , , — John Banta @ 5:02 am

Take the 1:5:10:365 challenge: Do one thing – for 5 to 10 minutes – 365 days a year to make our home and planet environment better.

1:5:10:356 EcoTip: Heat loss inspections are best performed when the temperature difference between the indoors and outdoors is at least 20 degrees F or greater. The large temperature differences make it easier to spot missing insulation using infrared cameras or a thermal leak detector such as discussed in :355.

:355 Thermal Heat Detector

Take the 1:5:10:365 challenge: Do one thing – for 5 to 10 minutes – 365 days a year to make our home and planet environment better.

1:5:10:355 EcoTip: Air infiltration and missing insulation in our homes is a major energy waster. Thermal imaging is a sophisticated way to have your home analysed for these issues – but Black and Decker has come up with an inexpensive do-it-yourself Thermal Heat Detector. It allows you to set a base temperature and then scan for temperature variations – which can indicate energy loss.

In the winter if you are inside the house, one would look for cold spots. Standing outside one would look for warm spots. If you are using it during the summer it would be the opposite.
