Passive Solar Energy: Improving Your Windows

If your home isn’t weather-proof, it is time to replace your windows with energy-efficient ones. By doing so, you can save money in heating and cooling costs. Plus, you’ll be doing something good for the environment!

Passive Solar Energy

Passive solar energy takes advantage of the building’s components to have ultimate control of the sun’s heat in your home. Everything is taken into consideration: walls, floors, roofs, windows, landscaping, and the building’s exterior. The purpose is to control how much heat from outside stays in or out to minimize energy use.

When installing new windows, consider your climate, window direction, and design.

Climate Affects Window Direction

Your strategy for controlling heat depends on whether you live in a warm or cool climate.

Warm climate homes benefit most by having the majority of windows facing south, and those windows must have glazing and shade. This way, you can let in the heat during the winter when the sun is low, and you can keep it out in summer with an awning when the sun is high. Windows facing east, west, or north should be used to let light in.

For cooler climates, you’ll need most of your windows to face north and south. In the summer, the shaded southern windows will block heat. In the winter, the northern windows will let it in. You may like to read the best bench vise, just click here

Window Design

Windows have three components that affect its overall thermal properties: frame, glazing, and type.

Choose a frame that insulates well and doesn’t require a lot of maintenance. Such frames include composite wood, fiberglass, and vinyl.

Glazing can be tricky to choose. For maximum energy efficiency, you should consider choosing a different glaze for each window, depending on the window’s orientation, direction, type, and material. To let less heat in, insulate windows by installing more than one pane of glass. The panes can be either airtight or filled with an inert gas. You can also add a tint or coating for extra heat absorption.

Last, you can choose how your windows open and close. Choose a type with a low air leakage rate so that you have more control over the heat flow. Awning, casement, and hopper windows all have low air leakage rates, and fixed windows are airtight.


The last step is to install your energy-efficient windows. Make sure they are properly installed by a professional because if you try to install them and they are not correctly placed, you could undo all the work you put into creating an energy efficient home!
