Older Homes – More Energy Efficient Than You Think

Older homes tend to get a bad rap for being energy inefficient. The truth is, many older homes have built-in energy-efficient systems that a homeowner should learn to use and, if possible, enhance. Here are some fake rolex examples of what I mean:

A stone or brick home with thick walls will retain heat in the winter and cool in the summer by way of its mass. Often, the older home will also have small windows on the third floor or attic. These are meant not only to allow light into the house, but also to allow hot air out in summer. Opening these small windows creates negative pressure inside the house, which then draws cool air from the basement. This is natural cooling at work. That’s because a basement’s mean temperature is between 60 and 70 degrees in summer. Utilizing this cooling air convection, combined with the thermal mass of the brick or stone home, means many of these homes can go several days at a time during a heat wave and not require any artificial air conditioning or cooling.

Since it’s heating season, we should also focus on some “passive” methods for making and keeping an older home warm.

Sash locks — These are the small closures on your double-hung windows you turn to lock them shut. You probably think they are for security, but they are really there to push the two sashes tightly into the sash frame and also to pull the sashes tightly together. This small piece of hardware makes your older wooden windows much more efficient by creating a tighter seal. Many older double-hung windows have not been properly maintained over the decades. The top sash might be stuck with paint, or the sash frame may be “out of square.” Other common problems are weights and chains that have failed. All of these problems can be fixed with some TLC and good carpentry. Happy to help; just give us a call.
