Cost Difference Between Conditioned Attic And Ceiling

Energy usage of about 40 watts at medium speed is typical.

Cost difference between conditioned attic and ceiling.

This calculation comes from a 320 square foot living room in a 2000 square foot home. A vaulted ceiling does not necessarily require roof insulation because there is an air cavity separating the interior of the home or conditioned space from the roofline. Making the attic a conditioned space taking the building envelope to the roof is a good approach and will save energy another approach is to use radiant coated deck sheathing seal all ceiling attic penetrations and blow in r 60 insulation as it will cost less than spray foam and should give at least the same energy efficiency to the home. It typically costs about 60 per square foot to raise a ceiling or between 50 and 75 per square foot the total price of a raised ceiling project costs about 19 200 and can range from 16 000 to 24 000 and up.

When set at low speed fans use between 15 and 30 watts and at high speed they consume between 50 and 100 watts. A cathedral ceiling requires some degree of roof insulation. The main advantage of spray foam is that it allows you to move the building envelope the boundary between conditioned and unconditioned space from the attic floor to the roofline. The electricity consumption of a ceiling fan ranges widely depending on the design and the speed setting of the fan.

Unventilated attics can help to mitigate energy loss through leaky ducts or ceiling fittings. Second typical roof slopes often leave inadequate height at the top plates for full depth insulation.

If you ve got your hvac system and ducts in the stupidest place they could possibly be the attic then moving the envelope to the roofline can be a good thing. Otherwise the fan will actually pull air conditioned air from the living area through cracks in the ceiling forcing the home s air conditioner to work harder. A home with an attic fan must be completely sealed between the living area and attic. However if moisture is able to enter the unvented attic space it may lead to roofing panel issues.

It also must have sufficient soffit 1 and roof ventilation for the intake of air into the attic. Attic spaces above insulated ceilings to accommodate design and cost concerns. If the air distribution is in the attic space then consider insulating the rafters to move the distribution into the conditioned space. The energy savings touted by unvented attics can be as high as 20.
