700 ft^2 2nd floor Apt. Entergy $101 August bill, for July $115 July bill, for June I put my thermostat on 82F when I leave for the day, and turn it down to 75F when I get in for good.
Mine stays at 80 all day, 70 all night. 1500 square feet. $325 with Stream. My house is drafty as hell, needs new insulation and probably a new central a/c unit. It also needs the duct work if not completely re-done, it needs to be fixed. Frankly, I'm surprised it wasn't worse.
I had new insulation blown into my attic and its made a huge difference in my electric bill. I'm also thinking about getting a wind turbine installed on my roof. I would also like to replace my windows w/vinyl replacement windows...
Ventilation During warmer months, ventilation helps keep attics cool. It helps prevent hot, moist summer air from warping the roof sheathing. It also stops shingles from deteriorating prematurely. What's more, fresh air in the attic makes a home much easier to cool, which can result in lower energy costs. In winter months, ventilation helps reduce moisture to keep attics dry. It stops water from backing up under shingles, damaging insulation, and rotting the roof structure itself. It also helps prevent ice dams from forming. Ice dams occur in areas where snowfall and cold temperatures are common and pose a special problem because they prevent melt water from running off the roof. They can even cause leaks inside your home, resulting in drywall damage. http://www.airvent.com/homeowner/whyVent/whyVent.shtml
1850 sqft townhome built in 1975 - 2 floors 83 during the weekday - no one is home 76-78 when home $112 with Green Mountain Energy Wind. Switching to Reliant Wind - would have been around $101 with Reliant Wind.
No, there is a filter inside that keeps the bugs out. It is used to suck the hot air out of your attic.
I do (I just built my own home and had my whole HVAC system customized) But don't ask me. Just go look at all the newer homes and see how many of them have those.
We have a 1500 sq ft home. The temp durning the day is around 79 and about 75 at night. The bill comes in at $140-$160 with Entergy.
As a matter of fact, I don't think those wind turbines comply to Houston's building code any longer. I had my roof re-done two years ago. When they told me they were going to replace my wind turbines with the newer flat ones, I asked why can't they just use the old ones, and they giggled and said they didn't want to lose their license.
Im sure you can still use them, they are just obselete, and don't do any good anyway (even the flat roof vents). Radiant barriers and ridge vents are the in thing as far as keeping heat out of the attic. The problem is, with heat rising, unless those turbines and flat vents are on the tip of the pitch of the roof, there is no way for heat to escape through them. Heat rises. It doesn't go sideways.
invest in a radiant barrier too youll make up the investment quickly in energy savings also, always remember this ....you can never have too many return air vents i have 8 in my house
Do you know anything about radiance paint in the attic to keep the heat out? Does this work? http://www.advancedsiding.com/radiance_insulation.htm
