Re: Help blocking heat from sun SE side of house

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.

How about a portable AC unit (freestanding, not window)? I got one a few years back for the bedroom which is located on the southwest corner of the house in AZ and was poorly insulated. Works great, easy setup and only a few hundred $$. Plus it is movable if needed.

I'll check into these...Any idea of how hard that hit your power bill?

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.

There are special thermal backed shades that work wonders, they're $15 each at Wal-Mart.

I use both a sun screen on the outside of my windows and a honeycomb shade on the inside. Helps quite a lot and looks good.

Some heat may come through the windows, but most is coming through the walls. The surface of the walls is much larger than the surface of the windows, and realistically no insulation will help when the siding heats to 140-150F.
Get a portable A/C - that's pretty much your only realistic solution.

I had the same problem on the south and west windows here in California. When I lived in Phoenix, everyone used Gila Film.
I found it here at Home Depot 10 years ago, still on the windows today. Grey tone, or the bronze. Grey is totally unnoticible from the outside, bronze is a little bit noticible.

Way less heat, no more fading of carpets or wood floor (Slider).
Still looks good after 10 years and cuts the 'glare' allowing me to work on the PC and stil have the natural light.

A lot of the heat is likely coming from the roof especially the darker it is.

I had a new roof put on an got the lightest (almost white) shade of shingles I could.

Proper attic ventilation is important too.

Get ridge vents installed if possible.

Soffit vents if applicable need to be big enough.

A cheaper alternative to a new roof is to snow-coat the roof.

I tried running a Proliant DL380 server in my office.

That heated up the office a lot so it's now in the garage.

We use very thick fabric shades in the upstairs loft and when they are closed the loft is easier to cool.

Good luck to you.

How hard was the film to apply, and is there a chance of taking it off with minimal pain? I really didn't want to go this route, but looking at the alernatives open to me, this may be the cheapest.

Very easy to apply, they also sell a low suds soap, xacto knife and tiny squeegee to go with it. Cut a little larger, spray the solution, put on the film, slide it around, trim and squeegee if I remember right. The Gila site has install instructions.

It pulls 900w/hr when running. It actually saved me money because I didn't have to cool the entire house for 1 room. I did a write-up on the original which is here: »Re: Thoughts on Portable Airconditioners . It's been 3 years and still going strong, used almost daily and during the summer for 8-10 hours/day. About once a year I do open it up and clean everything out and grease up the fans, but cooling wise still strong.

I'm in the same boat as you are. I've got full tint on the windows, insulating drapes, fully insulated garage, the works.

The only way you're going to fix this issue is to put active cooling in that room (either via window A/C, portable A/C or getting your house A/C adjusted/fixed/whatever to address this). I have an LG 13kbtu upright AC unit »www.lg.com/us/portable-air-conditioners that vents out the window on a dedicated 20A circuit.

Even with 2 registers and a return in that room, the house air just can't keep up with the heat demands of that room (even with the electronics off).

When the time comes to put a new A/C system in the house (probably in the next 5-8 years, system is 12 years old now) I'll ask a lot of questions about how to cool that room without using the upright. Until then, that's the only solution.

I'd say, middle of summer cranking full blast, it adds probably 50-75 to the bill.

Also, because the house air takes care of the humidity, this thing *never* needs to be drained. Ever.

Stay away from the Frididaire products. They're made by Whirlpool now and they SUUUCK. My first upright was a Fridge. It worked one day. I turn it off and unplug it to go on vacation. Come home a week later, plug it back in and it would only dehumidify. It wouldn't cool.

The warranty process suuuucked. Eventually got a replacement. It died 8 months later. Got an LG and have been happy since.

Thanks for the post.

I read on another site that adding a return to this room may help things....anyone have any thoughts on that?

Not sure if I am allowed to post links as a guest, but a simple search of Wal-Mart.Com for Thermal Backed Curtains found this:

»www.walmart.com/ip/Premiere-Ther···10924062

I have the shorter ones on my windows since they're smaller windows.

cheap method is foil on the inside of the windows. tape it up and in the winter just pull it down. IF this gives the needed results, then you can work towards buying proper black out curtains.

Low-E window film. Dark tint is useless unless it is Low-E.
You can get rolls of it a Lowes or HD.
»www.lowes.com/SearchCatalogDispl···dow+film

Or replace the windows with triple-pane Low-E windows....you can get 2 Low-E coatings & argon layers in a window like this.

If you're going to be in the house a while, consider planting some pyramidal cedars near the window (2'-3' away). You can get them up to 7' tall at most nurseries and if you water them 3+ times per week they will grow about 2' per year until they reach about 20' tall. This will prevent a lot of the solar gain from reaching the windows in the first place.

Consider what you're using the machines for - can you downsize to a newer set of laptops for better compute power and less heat? How about Intel Atom or equivalent powered machines?

The only thing I'll add is not to get film that goes on the inside of the window. It can ruin windows. Only get products that apply to the outside of the window.

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.

Now that is something I hadn't considered. I don't know if thats the case or not, but it does get pretty damn hot up there....but it's also insulated pretty well. I forget to which rating, but its the cellulose stuff, and pretty deep.

But you're right, it is right against the attic.

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....

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.

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.

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.

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.
