Keeping Your Older Home Cool

Keeping Your Older Home Cool

In most cases, older homes are poorly insulated. Energy codes have gone through much iteration over the years, helping to make homes more energy efficient. A well-insulated home holds in warmth during cold weather and keeps out the heat on hot days. Current codes require the entire exterior wall cavity to be filled with insulation, including insulated headers over doors and windows, but this has not always been the case.

 
In an older home, the attic may have little insulation and over time, what is there may have been disrupted, providing leak points where warm air escapes in the winter and hot air gets in during the summer. Also, your attic may not have attic venting. Substandard venting leaves the hot air that collects on warm days to take the path of least resistance out, which may be down into the house. Windows are often another weak point. It is possible that your home might still have single-pane windows as opposed to the double and even triple-pane windows available on today’s market.
 
There are several remedies that can help, depending on the design of your home and the budget you have to spend on solutions. A good first step would be to consider getting an energy audit to help you identify problem areas. Some utility companies provide energy audits for no or very low cost so it would be worth checking with your local utility company.
 
Some of the steps that can help you keep your older home cool include:
 
·       Plant shade trees or vegetation to keep the strongest sun rays from heating your home.
 
·       Provide awnings, trellises or other built structures outside of your home to keep the sun from beating down on your windows.
 
·       Consider replacing single-pane windows with double or triple pane with argon/insulated windows to minimize heat transmission. Windows can also be tinted to reduce solar heat gain. If you do choose to replace your windows an added benefit is that you have the opportunity to seal any gaps where leakage might be occurring during installation. And don’t forget, most energy-efficient windows have rebates associated with them.
 
·       It is difficult to add insulation to walls but many times attic space can be easily accessed to blow in additional insulation. Also attic vents can be installed to help the heat that gets in to escape since heat rises and will collect in your attic. Another often effective measure is to install an attic fan that is connected to a thermostat. It will help push hot air out of the attic.
 
·       If exterior doors are the source of your leak, new caulking to seal or weather stripping could help you keep your home cooler in the summer and warmer in the winter.
 
·       Whenever possible, take advantage of cross-ventilation by opening windows on opposite ends of the house to increase airflow. This is especially effective if you keep the house closed during the hottest parts of the day and open it up as the temperatures drop.
 
·       Ceiling fans are very effective for circulating the air but even fans you get at the drug store can help and they get quieter and more energy efficient every year.
 
Here’s a final tip; if you are thinking about getting window unit or free-standing air-conditioners, try to shop for them off-season before demand and prices spike.
