Air Conditioning 2.0

Making the Most of our "green" Historic Homes

!–[if !vml]–>We have become so reliant on Air Conditioning and heating that we sometimes forget to take advantage of the inherent good design found in our historic homes. As the weather gets more pleasant this fall, consider taking a few steps to operate your historic house more energy efficiently, and save some money in the process. The following are some ideas to consider:

1. Unstick any windows that are painted shut. It is almost a universal trait of old homes to have at least one window that won’t budge, but when more than half aren’t functioning, it’s time to take action. A web search for “windows painted shut” brings up countless websites with step-by-step instructions for loosening stuck windows, including HGTV and This Old House (they offer a video). Releasing a stuck window is not rocket science, but it generally requires some muscle and patience. Professional help can be called in, particularly if you need to reattach the counter weights; just beware of anyone telling you to replace your wood windows. There are good contractors in the area that can repair your windows, preserving the character and integrity of your home as well as keeping dollars in your pocket.

2. Install wood framed screens on windows if they are missing. You are more likely to open those unstuck windows if you aren’t worried about welts from mosquitoes. As a bonus, wood window screens add historic character and an additional accent color to the building exterior.

3. Install wood screen doors on all exterior doors. Wood screen doors should be heavy duty since they open and close as often as the primary door; if the model you see is made with thin, finger-jointed wood or comes with a diagonal wire support, don’t expect it to function properly for more than a season or two. Choose self closing spring hinges rather than ugly vacuum bars for a more authentic design for your historic home.

4. Install awnings, operable shutters or blinds over openings on south and west elevations. When appropriate for your house style, they provide a nice architectural accent in addition to functioning as a shading device. Close shutters and blinds during the hottest parts of the day.

5. Install ceiling fans and use in conjunction with open windows and doors.

6. Install a solar powered ventilation fan in the attic to help remove excess heat. Turned on by a temperature sensor, this relatively inexpensive project will help reduce your cooling load next summer.

7. Caulk or foam-seal penetrations into your house (where the cable enters, water lines penetrate, etc.) and install weather-stripping around windows and doors. Air infiltration is good when you can control it by opening windows and doors, but bad when the air you paid to heat or cool escapes.

8. Insulate your attic space; most heat loss and gain comes through your roof. If you expose exterior wall framing during remodeling, install insulation as part of the project. Don’t remove plaster walls just to insulate though; plaster is a surprisingly good insulator and reduces noise transmission from room to room.

9. Plant some shade trees on the south and west sides of the house. Trees are a long term investment in the environment, providing cleaner air, habitat for wildlife, reducing soil erosion and sheltering from the sun. Your historic house has shown that it appeals to multiple generations already, so even though the trees you plant today may not have much effect on energy bills for a while, the next owners will thank you.

10.  Sit on your front porch rather than watch TV in the early evening a few nights a week. We tend to decorate our porches with inviting rocking chairs and beautiful potted flowers, but rarely take advantage of the peaceful atmosphere they provide. In addition to the pleasure of a cool, relaxing evening, you might find one of the other benefits of living in a historic home: friendly conversation with your neighbors.

Great Information on How to Solve Air Flow Problems in Your Home

Solving air flow problems in your home

Basic things that the homeowner can check to help air flow:

First and foremost, check your furnace filter to see if it is dirty and if so, remove the dirty filter and install a new furnace filter. Plugged furnace filters restrict air flow by creating a pressure drop. Next, walk around your house to see if any cold air returns have anything such as couches, rugs or cabinets obstructing the vent. If anything is obstructing the vent, then remove these obstructions so that the cold air return, which is an air intake, can draw in enough air. Last, but not least, walk around your home to check to see if all supply registers (heat vents that blows out air) are open. All supply registers should be open. A popular homeowner misnomar, is that by shutting off certain vents throughout the house will cause other vents to blow harder. This simply is not true, because CFM (a measurement of air flow, cubic feet per minute) is determined by the pipes diameter and only so much CFM can ever blow out due to the size of the round, regardless if other registers are shut off or not. Shutting down too many supply registers usually causes more harm than good by creating pressurization problems with the overall duct system, that in an extreme case can actually cause your furnace to short cycle on a high limit and hence increases the cost on your utility bill while working key HVAC components and parts to reduce their life expectancy. Never buy and install heat vent filters either, because these filters really cause pressurization problems too. If there is too much dust blowing out of the vents, then the best thing that you may consider is to have the HVAC system cleaned out thoroughly with the power vacuum/air sweep method in air duct cleaning by an ACCA (Air Conditioning Contractors of America) member company. An average price for a 1 furnace home would cost between $400.00-$700.00 to do the job correctly, depending on where you live in the country and depending on the service providers cost to operate.

Some solutions that an HVAC company or contractor may suggest:

Very often in older homes, air ducts are sized incorrectly due to building departments in the past not emphasizing the importance of properly sized air duct construction and the by the fact that the builder wanted to save a buck to construct his own ductwork rather than paying a heating and cooling professional to install the ductwork properly. In recent years, many building departments throughout the United States really have zeroed in on enforcing proper duct design, so in most newer homes indoor thermal comfort has improved drastically. Some of the things that your licensed HVAC company or contractor may suggest to you to drastically help your older homes air flow is as follows:

• Let me tear out all of your ducts and start over! (That would be sweet, however in many instances that is just not practical due to cost, time and a big mess!)
• I can bandaide your homes HVAC system by replacing your old inefficient furnace with a Rheem 80% AFUE 2 stage variable speed furnace equipped with the GE ECM motor. Visit www.luckyduct.net to learn more about the GE ECM motor. The GE ECM motor operates 30-40% more efficiently than a standard conventional multi-speed motor and sustains constant CFM even if your ductwork is undersized and restrictive. What this means is that vents that seem to never blow air with your inefficient old furnace will all of a sudden blow air after the new Rheem furnace equipped with the GE ECM motor is installed. The ECM motor also allows homeowners to qualify for a $50.00 EPACT tax credit that you can receive when you do your taxes, so even the Federal government wants you to go for it!
• For some reason your home does not have enough return air openings to even allow enough air to enter the duct system at all! We need to build additional return air openings into your ductwork so that we can get additional CFM into the HVAC system so that your AC indoor evaporator coil can stop freezing. Good golly, you’re paying more money on cooling not to mention the fact that your AC doesn’t even keep your house cold enough! Let’s fix that and add some new return air openings so that you can save some money on your utility bill and actually cool down this summer too!
• Let’s go ahead and rip out the 4″ diameter supply runs and install 6″ diameter runs so that we can circulate more air into that sun room!
• You know, your ducts amazingly enough are sized correctly, but all of the air is escaping into unfinished portions of the house because the construction of the ductwork is very loose. Let’s go ahead and seal up every trunk line connection, brace, joyce and end cap with mastic duct sealant. By sealing up every duct connection on the entire system we’ll see if we can blow those curtains side ways afterall! No, just kidding, but the air will come out a touch harder, though as a result in sealing up the ductwork better and you will see a significant reduction in your utility bill because the system will only cycle half as often now.
• You know, for some reason all of your ductwork is sized correctly, but the return leg that is attached to your furnace is severly undersized and is acting like a choke point. Lets rip this leg out and install a bigger one with a greater dimension!
• You know, your homebuilder really got cheap and should have installed 2 seperate systems considering that your home is 3600 Sq/ft. Two smaller systems will actually cost you less on the utility bill to operate and will provide greater comfort. Save up some money and lets build that second system in the attic!
• You know, the most cost effective thing that I can think of that will improve your indoor comfort tremendously is to simply just zone your current system so that 3 different thermostats will control 3 different temperatures in your home. Aprilaire and Honeywell make great zoning systems and we usually can get this system installed from $3800.00-$6,000.00 depending on how fancy of a system you want to have installed!

You see some of these bandaide jobs will cost just a few hundred dollars, while some solutions may cost a few thousand dollars, but in the end after the corrections are made, your utility bill will probably reduce a bunch and you’ll finally have true indoor comfort that you didn’t have before. Many HVAC companies and or contractors will give you more than one option to consider as well so that no matter what you decide on some sort of indoor air comfort solution will be achieved to atleast improve the comfort situation. The best thing that you can do as a homeowner is to select an ACCA member heating and Air Conditioning company or contractor to ensure that your comfort specialist has all of the latest and greatest training, tools and professional assistance to best serve you as a customer. In the long term you won’t regret it because you will save some money on the utility bill and you will be much more comfortable in your home as a result.

what alternatives is there to auto air conditioning, that i can plug a system into my cigarette lighter?

There are some mini air con devices that will plug in and provide some cool air, but nothing that will provide cooling as good as a proper air con, the typical cooling power required for car air con runs off the engine and a cig lighter won’t give that power, it will also be too big and need an external radiator to be effective. Not worth the money.

Solar Attic Fans

One of the more popular uses of solar power in the home is the solar attic fan.

As its name implies, a solar attic fan is powered and activated by sunlight. It is installed into the roof of the attic, with its panels facing the sky.

Why would one need a solar-powered attic fan?

Well, for that matter, what is the purpose of an attic fan?

Since heat rises, all of the heat in a home tends to rise up into the attic. If this heat has no easy outlet, it will simply get stuck up there. This causes the over-heating. When combined with a lack of proper ventilation, this leads to dampness, mildew, and the the like.

Furthermore, when the accumulated attic heat is not allowed to escape, the temperature of the entire home rises.

While there are some circumstances under which you want to warm up your home, there are other circumstances under which you would prefer to cool it down. A lack of sufficient ventilation in a hot attic can make matters difficult. Thus, an attic fan can play an important role in allowing you to control the temperature of your home.

Okay, now that we understand what the purpose of this fan is, why would we want it to be solar-powered?

The first answer is obvious - to use greener energy and to avoid using energy sources which damage the environment.

By using solar power for the fan, we can also save a bit of money on electricity.

But a more pragmatic reason for using a solar powered fan is the simple fact that it is basically “wireless.” You won’t have to worry about installing electrical wires and cables into your attic, in order to run your fan.

Solar-powered fans are relatively simple to install into one’s attic. But if you aren’t an enthusiastic DIYer ready to climb onto your roof with a knife and a hammer, you will probably want to get someone else to do it.

When installing a solar-powered fan into the roof, one has to actually cut a hole into the roof and install the fan in that spot. It’s smart to install it on the south facing side, which will receive more sun (unless you live in the Southern Hemisphere, in which case you would obviously install it on the north side). There is a certain degree of skill involved, as is normally the case when one considers the prospect of climbing up on the roof, removing shingles and roofing material, and cutting a hole through to the other side without damaging any rafters.

But overall the process does not take a long time, for someone who knows what they’re doing. The installation of the fan should be well worth the trouble in the long run, particularly if you live in a hot climate. It will run at virtually no running cost, while reducing the overall level of heat in your home. That reduces the costs involved with cooling your home (using less energy-efficient methods, such as Air Conditioning).

So, even if you don’t give a hoot about the environment, a solar attic fan might be a very worthwhile financial investment. Providing you do have an attic.
