Easy Energy Savings For Older Homes
If you live in an older home, especially if it was built during a rapid growth period to support industries long gone, it's very likely that you live in a wooden box that allows much of your heated or cooled air to escape with ease. It's likely that this old and ancient form of home construction is responsible for your energy costs being three to five times greater than that of a similarly sized new home.
Why is this? Why is your home missing many of the basic things that are standard on new homes? There are a few possibilities...
- since coal and wood heat were so cheap at the time of construction, thoughts of sealing the home may have been viewed as an unnecessary expense.
- the home was deliberately built to allow air to enter the home since the use of multiple coal or wood burning stoves required large amounts of fresh air.
- the home was built as quickly and as cheaply as possible to entice families to locate there in an effort to increase the available work force.
The two major issues with older home construction is excessive 'air infiltration' and inadequate 'insulation'.
AIR INFILTRATION
Air infiltration is the process by which air enters through cracks and crevices in the siding, through roof overhangs, and around door and window frames. Infiltration, or 'drafts' is the direct result of 'loose construction' due to the lack of seals around the edges of doors, windows, siding and roofing.
If it were possible to find and measure the length of the crack around every window, door and unnecessary opening, your total crack length could easily surpass 300 linear feet (16 linear feet per window, 20 linear feet per door and 100 linear feet to cover all remaining cracks and openings). If the average crack width is just one-eighth of an inch in size (I'm being conservative) and the length of crack is 300 linear feet (3600 inches), the actual hole size, were it to exist in just one place, would be 450 square inches or a hole that is 21.2 inches wide by 21.2 inches wide. In essence, you have a 2 ft. x 2 ft. window wide open all year long, regardless of how hot or cold the outside temperature is.
Your goal is to find a way to shut that virtual window. Short of totally renovating the home, you'll never eliminate every draft, but you can make a noticable dent if you do what is necessary to reduce the amount of air infiltration to one third or less of its current level.
INADEQUATE INSULATION
Insulation is gauged by an 'R-Value' which is simply a measure of 'R'esistance to hot or cold. The higher the r-value, the harder it is for heated or cooled air to pass through.
The outside walls on newer homes are often insulated to a r-value of 19 or more. Their attic spaces can easily be insulated to a r-value of 30 or more. In comparison, most older homes have inadequate insulation values that struggle to reach an r-value of 2 to 3 if you give credit to the layers of wood and siding, but this is almost negligible.
Even the tiniest bit of insulating can make a big difference. When performing heating load calculations, a wall with no insulation gets a heating loss multiplier of 19, compared to having a multiplier of only 6 if a 3 1/2 layer of R-11 insulation were added. That first level of protection decreases the loss of heat through the wall by 3 times! Even more phenomenal, an attic ceiling with no insulation gets a heating loss multiplier of 42. This too can be reduced to a multiplier of only 6 by adding that first layer of R-11 insulation, decreasing the heat loss by 7 times!
More insulation means even more savings. To further cut your heating loss in half, increase your insulation value from 3 1/2 inch (R-11) to 6 inch (R-19) where space permits. Your goal is to increase your homes resistance to outside temperatures by twice its current value or more.
- WINDOWS
When looking at older windows, you have the following options:
1. If the window has a single pane and its storm window is missing or damaged, don't waste your time and material on repairs since it would be more cost effective and quicker to install a modern replacement window that will seal better and be easier to use and clean.
2. If the window is single pane and has adequate storm windows, replace any missing or loose caulking around the outside edges of the window pane(s) and re-caulk around both the inside and outside of the storm window, leaving the bottom weep holes uncaulked.
3. If the window uses weights to open and close, a large area exists next to each window to hide the weights. Remove the moldings that cover the weights and seal each inside corner edge of the cavern with non-expanding foam spray. Once dry, pad the back area with R-11 to R-13 insulation. Be sure to leave adequate space for the weights to move.
- If the ropes to your weights are broken, replace the lines with new. Clothesline rope generally works fine.
4. During colder winter months where the window would not normally be opened, you could also encase the inside of the window by installing a heat shrinkable plastic kit.
5. If the solid wood frame window does not close enough to allow for the locking mechanism to engage, the window will not be able to be closed tightly. It may be necessary to remove the bottom window and plane its bottom edge to provide additional space for the window to close properly.
6. If the window closes well, but it's obvious that the window is not sealed tight against the window base, foam based weather stripping could be installed on the base of the window to help create a better seal.
- Many older wooden windows have uneven gaps at the base, making the use of weather stripping difficult. To resolve this, open the window and place a large bead of caulking on the window sill along the entire width of the center of where the window would close. Cover the caulking lightly with plastic wrap, overlapping the caulking by several inches both towards you and away from you. Close the window gently and tightly and let sit for at least 24 hours. Once the caulking has cured, open the window and remove the plastic wrap, and behold, you now have a weather seal that fits your window base perfectly.
- DOORS
When looking at older doors, you have the following options:
1. If the door is a solid core wooden door with a large section of single pane glass, cut a piece of Plexiglas one half inch larger than the total width and height of the glass. Using clear silicon caulking, apply a thin bead along the perimeter of the Plexiglas and set in place on the wooden door, over the glass area, leaving a void between the existing glass and Plexiglas. Add a border molding as desired.
2. If a storm door does not exist or if the existing storm door is in poor shape, install a new storm door.
3. For any type of door, add additional weather seals along the top and sides if air passes through when closed. Likewise, install new weather stripping to the base if air passes through when closed.
4. If an exterior door has an ancient skeleton key system, air will blow right through its keyhole. Replace this form of lock with new and you will eliminate this needless draft.
- WALLS
For a home that is not insulated or sealed, the volume of air moving within the walls and ceilings can be staggering. To resolve these issues, sort of performing an entire renovation where all walls and ceiling spaces are insulated, you have the following options:
1. All unfinished walls and ceilings in the attic should be insulated if possible. It may be necessary to cut through finished walls to get to some areas if access doors are not provided to get into any crawl spaces.
2. If funding permits, have insulation blown into all exterior walls.
3. In the basement where the top of the basement wall ends and the first floor wall begins, insulate and seal these spaces.
4. If you have a closed-in front or back porch, consider making this a true thermal barrier by insulating its walls and ceiling.
The bottom line is that there are inexpensive methods and ideas to reduce your heating and cooling costs, even if you have an older home. Start by doing just one room at a time and work your way down from the attic. Whether you have the finances to do this in a week, a month or a year, make it a point to do it and you will save countless dollars beyond what you spend, plus you will have helped make our planet a little bit greener.

Question dealing with a basic science experiment?
A fishery scientist questioned the ability of fish raised in a hatchery to survive in a wild environment. She believed the fish raised in captivity had lost their fear of predators. To test her idea, she placed 15 hatchery salmon and 15 river salmon of the same age into two separate, but identical tanks. She then placed a clear piece of Plexiglas into each tank. In each tank, she placed salmon on one side of the Plexiglas and a large predatory fish, the cod, on the other side of the Plexiglas. She then recorded the amount of time it took the young salmon to move to the back of the tank away from the cod. She found that the hatchery fish were much slower in moving away. This led her to believe that hatchery fish have less fear of predators than river fish.
Identify each of the following.
The control
The variable
The hypothesis
The data collected
The conclusion
Here we have a straightforward experiment. The only thing lacking is how she got her two fish samples, and what statistical test did she run to disprove her Null hypothesis.
In this case, each group is the control of the other group, the variable being how they were raised. There is a null hypothesis that the behavior of the two groups was the same in the presence of a predator. You should be able to figure out the hypothesis.
She recorded, and I hope she did this from timed photography, as it would be difficult to track each of the fish.... and she had to establish a zone away from the predator that she would score the entering fish, time (to what resolution?) they entered the zone. How she compensated for fish already in that zone before the predator was introduced, and how the fish were presented with the predator, are unknown variables.
The conclusion depends on the results of statistical tests... which are not given. So I don't know if her data was enough to disprove the null hypothesis.
Conclusion is that not enough information is given to really assess this, but that the trend appears to support her hypothesis.
The Diffa Dining by Design Show and Dinner
THERE were many fantastical table settings at the Diffa Dining by Design benefit exhibition and dinner in Manhattan Monday night, but the most inventive accessory was a bare-chested young man who sat, eyes closed and legs crossed, in a yoga pose at the Poggenpohl for MMPI "Morocco in New York" display. There were tables and potted trees on either side, and tent-like drapes behind him.
