Energy Efficiency Continued.

For the past couple days, we talked about Heat Pumps and showed you both The Head inside and The Compressor outside.  The Heat Pumps are the most efficient and environmentally friendly way to heat your home.

Today’s photograph does not have a direct connection to a Heat Pump, but it does directly impact Heat Loss.

Today’s picture shows you the Energy Performance Ratings for a quality Window.  Here’s what you are looking at:

  • U-Factor – a U-Value is a rating that measures the amount of heat that can travel through the window.  Obviously, the point is to lose as little heat as possible.  So, if you think about it, the U-Value which measures the amount of Heat Lost, then the U-Value should be as small as possible. 
    • Read this window sticker carefully, you will see it is for Triple Glazing, instead of two pieces of glass this window has three with two chambers to hold Argon Gas that helps trap heat inside your home.
    • Yesterday’s Heat Pump moved heat indoors and you want it to stay there.  A highly efficient Triple Pane window will help.
  • Visible Transmittance – this number measures the amount of daylight that passes through the glass.  Or, it measures how well lit you home will be, most of us want our homes to be bright and filled with sunlight.  The V-T is a number that measures this.
  • The US Map – the darkened areas of the map of the US is where this window is rated to perform the best.  Here in Vermont we need high quality windows that preserve Energy as best as possible.

What do you think?  Is the financial investment in Triple Pane windows a good investment?  Are Triple Pane windows something you should have in your new home?

Let us know your thoughts!
