Increase Energy Efficency of Fixed Pane Windows

We have 25 fixed single pane windows that are roughly 3 feet wide by 6 and a half feet tall in our house in Houston, TX.  Some of the windows face east, some face west and some face south.  We had film put on them, but there is still a lot of heat transferred through them.  What  can be done to improve their energy efficiency without replacing the entire window?  We need to improve their energy efficiency due to all of the air conditioning cooling we have in Texas.

Some can be updated with double panes the other consideration would be awnings.

Awnings will not work for several reasons.  How would you update with double panes?  Replacing 25 windows would be too expensive.

It would be expensive, it requires the sashes to be remilled to accept bouble panes. In our house we just installed shades, it made a big difference.

If I'm not wrong 3M window film will increase home's energy efficiency and thereby lower your overall expenditure by 40%. Bear in mind that, cheap window films are slightly less forgiving and shrink with heat. But good ones would ensure running your air conditioner system less frequently. They are our year round efficiency solution.

Poorly fitted or sealed windows would let in cold drafts during winters. Similarly, poorly fitted and sealed windows make it much easier for the warm air inside your home to get out.

Energy Information Administration (EIA) estimates that one third of the average heat loss happens through doors and windows.

Replacement is the best option for long term fixes, especially if the budget is not a problem. Same with renters.

Let me walk you through few energy efficient measures for existing windows. Mitigate heat loss and drafts through caulking and weatherstripping. They are cost-effective. According to U.S Dept. of Energy, estimates that cost of caulking/weatherstripping will nullified through lower utility costs in less than a year. Take help on caulking from this article (http://canglow.ca/how-to-caulk-your-windows-and-doors/). Draperies and window coverings are an added thermal barrier. Though less effective can help upto 25%. Insulating window panels or interior storm windows and window films are other simple cost-effective options.
