Re: Help blocking heat from sun SE side of house

Not as loud as the 2 Proliant 5500's I ran for 5 years in the garage.

Electricity is not bad when compared to the real money drains called AC, Pool Pump, Hot Tub.

Is your roof properly vented? If it is then the temperature in the attic should NOT be much more than ambient air temperature.

What colour are your shingles? Black? If so, re-roof with a lighter colour - grey, driftwood shades, etc....

Appreciate the suggestion, but thats a pretty pricey solution....unless you've got 10k I can borrow have?

(Fair warning: The 10k may not actually go to re-roofing the house)

How new is your roof?
"20-year" shingles are usually really only good for 15 years.

Less than 10 years old.

And as far as the temp in the attic...I live in SC, it's ALWAYS hot in there, but is it actively cooled / fanned...no.

I have the insulated drapes in the bedrooms of my apartment. One of the rooms has 3 walls facing outside so it gets real hot with windows on 2 sides in the summer and real cold in the winter. After I added the heavy shades it made a good 15 degree difference.

Any particular kind, or just something heavy? I would imagine that even if they absorb the heat from the window, it'd still just heat up the shade and thus heat up the room, no?

Was wondering if it needed to be reflective.

These are the brand I have. not quite the same style but they work real well to darken and insulate the room. »www.walmart.com/ip/Eclipse-Alexi···21907335

Any chance you could plant a tree that would grow to a large shade tree? This is slow process and may not be feasible, but it helps. Also don't plant it too close to the house.

Other then that, you could try adding insulation to that upstairs room.... and by all means, tinted windows and window shades DO help some.

Good luck!

Also, something I do to save electricity: This fan powerful, moves a lot of air... (but somewhat noisy). Really helps though, makes me feel better and saves turning down the A/C.

Thanks for the suggestions....I have a fan in the door now....haven't quite figured out if blowing in or exhausting out is more beneficial.

You can tell the temp diff as soon as you step into the hall, which is why I was wondering about putting a return in the office, to see if it would move some of that air.

Mini-Venetian blinds! Cheap and effective... short of window tinting or window replacement.

You don't need to 'fan' the attic.

Just make sure that you have proper unobstructed air paths between soffit vents and peak/ridge vents and it will cool as close to ambient as it can via natural convection.

Do this and the other suggestions I made, add in some blinds/curtains with either a white or silver back (or Hunter Douglas honeycomb heat blinds) and you're doing all you can using passive means without spending big bucks on A/C units.

Rule of thumb: "Hot air rises"

How much hot air is your lower floors pushing to the upper? Insulating or otherwise trying to combat the heat on the upper floors "may" start with what is below you.

Just some food for thought. It helped a friend of mine out with a similar problem.

Options:

Cheap:
-Low-E film (be wary of metalized films if you depend on cellphone reception, etc...) I've never used this so YMMV.
-Levolor blinds (»www.levolor.com/products/cellula···ings.php)
-room fan (exhaust)

Higher cost:
-HVAC return (you mention there is none) $$$-$$$$
-Mini-split (samsung or other wall mount) $$$$
-Low-E window installation $$$
-awning $$$

If the sun is heating up that room from window, and there is thermal contribution (server farm?), you might consider reducing both sources of BTUs or cooling the PCs more efficiently, along with reflecting the sun.

I think a tree is nice green thought but time, leaves, weather, height, species... may not be practical.

Our sunrooms are the same way. They tend to get very hot even with the blinds closed. I would put awnings on it but it is base housing and a historical building so that won't happen. No AC vents in there either. Some people have put the portable AC units in there which work well. Some have put the window AC units in there as well. I personally use a fan in the doorway. I use this fan. »www.lowes.com/pd_153139-24099-49···cetInfo=

I have it sitting a few outside the sunroom directing the cooler air in. And since I can direct the air a little better I aim it for the area I usually will be at. Yes it is a little noisy compared to other fans but it works for me. It can really blast the air into the room, far better than your typical fan, imo.

Small thing but if using a hot HD or two, the new SSDs are very efficient, low wattage, and no fans since stay cool.
Had a friend who put a big fish tank in window. Cool and its presence is soothing. Rem that hot air rises so upside down shades are cool. Run them up from bottom, leave them down at top for heat to escape when not on a/c.
Avoid foods that jack up body temp on hot days - coffee is bad one. Go with ice tea or Skinny water things.

I would say portable or window swamp cooler (evaporative cooler) which hardly use any electricity. But being in SC which has some humidity to it probably would not work to well (must be in low humid area). Here in the low humidity desert climate they work like a charm and save on the electricity the A/C uses. I have one in my man cave, also one on the patio, and in the garage.

Many good suggestions already made, so just some basic thoughts. South Carolina does get hot in the summer but the humidity is also a factor in SC!

With no AC register in the room being discussed I suspect the humidity may make the room 'feel' hot so a dehumidifier could help. An excellent dehumidifier is the Winix model WDH871. Home Depot sells a Winix model very similar but theirs does NOT have auto re-start (if you seldom have power outages or you are mostly home to restart the unit after a power outage then this feature is no big deal). Costco also sells these units. But, most places are out of stock until the humidity season begins again in the summer. Also, where would you put the water drain hose? Or buy a unit w/o the built-in pump and you empty the drain pan as needed. Winix is a good brand IMO.

The suggestion to use a thermal heat gun to identify the areas of highest heat is excellent - you can buy cheap guns from Home Depot or Harbor Freight (and always use the 20% off coupon). Point the gun at the ceiling, at the window, at the floor, etc - where is the heat coming from?

If you have a typical sub-division home built in SC the ridge vent / soffit vent concept probably does not work well. You need to go up in the attic to check this concept - see if the soffit vents are plugged up with insulation. Does there seem to be air movement up and out the ridge vent - if not then the attic temp will get very hot and the heat will move thru the attic into the rooms below.

You can put in gable vents (even powered ones) but they will defeat the air flow of a properly working ridge vent. Or maybe a window exhaust fan to move the room heat out of the house and draw in some cool (and dehumidified) air from the AC cooled rooms.

good luck

Don't know about ruining windows. Inside solar film is common in Florida. It's removed with a solution of dish detergent and some ammonia, along with a razor blade. (Been There Done That, etc.)

My post is a bit of an addendum or add on to the op that is posted both for reference to the OP and to seek related advice regarding my situation.

I live in a bungalow with a V shaped roof. One half of the V faces south. I live in one of the warmest areas of very sunny California.

For the first twelve years I lived here a giant oak tree provided shade to large areas of the roof.

Then this spring the oak needed some serious trimming. The result produced a fully exposed to the sun south side of the roof. I have A/C but on warm days and definitely on hot days it can't even begin to keep up now. Before the trimming, no problem. My hot month electric bill has now doubled.

I don't have a solution for the afternoon in the summer but after the sun sets and the outside temperature drops a cheap but efficient special window fan helps a lot--but still not on par with an A/C.

The fan is a unit that has two fans and the unit is very portable and lightweight. It is very adaptable adjustable to fit any window and incredibly light as well as simple to put in or take out of the window. You simply open the window and whether it opens vertically or horizontally you easily can temporarily position the unit in the open gap. The two fans in the unit have three speeds and both fans can be switched independently to either exhaust air from inside out or to suck in air from outside to the inside.

Since the tree has been trimmed the temperature of the roof is hot to the point that if you touched the roof you would immediately significantly burn your hand.

Bottom line is if the temperature outside is below a certain point, oh about 80, the fan unit I described is excellent and it contribution dramatically increases with a decrease in the outside temperature. It would be even better if I had a second one that could supplement the one I have now. (By the way the electricity to run them is minimal and they are very quiet.)

Looking at the temp readings provided as 83 outside and 90 inside and depending upon the sunlight the fans I refer to potentially would really help. (They are also relatively cheap to buy and surprisingly are very long lasting or durable.)

ADDENDUM: For me I mentally wonder if some sort of artificial or man made "structure or screen that was practical and cheap could be made to provide shade for the south side of my roof as the sun beating down on and heating the roof is 90 percent of the problem.

Currently , it says it's 78.4 in the office....nice and cool in comparison to what it normally is, but the thermostat for the rest of the house is 74. I don't expect to reach that temp, but keeping it below 80 would be nice.

Partially closing the A/C vents in the rest of the house and opening the vent in the office all the way might balance out the temperatures better.

A dehumidifier does put out heat also when running. So may be a catch 22.

Are you sure it is the solar heating through the windows and not radiant heat from your ceiling that is the biggest culprit? I am presuming your upstairs office ceiling is adjacent to the attic space. If there is not adequate attic cooling and ceiling insulation, you could be getting a lot of heat that way.

And is the attic space properly vented? If the insulation goes right out into the eves and the soffit vents are blocked, you are creating an oven up there. Proper attic air circulation is essential.
