Here is a little fan called the "Air Booster" by Field Controls that is already installed inside a duct. You just cut into a ventilation or heating duct and replace a little section with this little fan and you can get a boost to the air flow. In-line fans can do the same thing with more power,...
This is a special story.
The biggest hole saw you can find on the shelves of hardware stores across Canada is 6 inches. All the companies stop at 6.
But you can't put the new 6" ventilation ducts through a 6 inch hole, you need a little more. So I personally pushed Starrett Tools to see if they...
"Energy Efficient Housing -- A Prairie Approach" is the only book I know of which advises against this practice (check out the graphic, keyword "ventilation", title "WHAT IS A CONTROLLED COLD-AIR INLET?"), so I asked the Saskatoon Research Council why. They are not against the practice in genera...
No! Large-blade ceiling fans, even the simplest and least expensive models, will do no more than equalize the air temperature in a room (making it feel warmer for the same amount o furnace work) and slightly lower the temperature on the ceiling (which means less heat loss through the ceiling). ...
Yes, a vent hole without a damper will cost you heating dollars. Generally they should be closed with dampers. However, if the vent hole is not an uncontrolled leak but a planned part of the system necessary to create a high neutral plane, then a damper should not be used. It will cost you muc...
Vent yes, turbine no. A vent on the top of the roof is designed to let hot moist air out of the attic. It is critically important that air can get into the attic as low down as possible, ideally up through the soffits. This air then feeds up and out the roof top vents. When there are little o...
-- Take care of air barriers, ventilation and vapour barriers before insulating. Check out these three topics in the Search Tab above.-- Don't block the eave vents with insulation.-- Do cover the top of the outside wall.-- Don't put plastic foam on top of porous insulations (batts, loose fill) a...
Ventilation in a Canadian attic does very little to remove moisture when the temperature in the attic is below freezing. During that time, the moisture is in the form of Ice and the passing air simply won't remove it -- whether you have passive vents or power vents. When things warm up, if the ...

Answer One "Planned-holes-high-in-the-house" are part of buiilding science considerations as to how air moves in buildings creating pressure differences that can help to keep houses dry and mold free or can help to trap pollutants in the house or even in the walls.A planned-hole-high-in-the-house...
