Using Passive Solar Windows for Home Heating & Cooling

Installing passive solar windows is a one-time investment that can help you save energy over a long period of time. During summer, it can help keep the heat out and the cool air in. During winter, it can help keep the heat in and maximize the heating rays of the sun.

However, the effects of different climates means that people need to position and install their windows differently to take advantage of solar windows' various properties.

1. Passive Solar Windows for Hot and Sunny Climates

In hot and sunny climates, glazed windows should be installed towards the south of the house.

This allows the windows to collect heat when the sun is low in the sky during the day. That means the house won't overheat by allowing the sun's rays into the house during peak hours.

You can also use a number of shielding devices such as awnings or overhangs to prevent overheating during summer.

Other windows in the house can still be installed, but they should have a shade or glaze installed so they let less light into the house. Having north facing windows in a hot and sunny climate can also lead to overheating.

2. Passive Solar Windows for Cool Climates

There are two main strategies for heating up a home with passive solar windows in cold climates: trombe walls and using a greenhouse methodology.

A trombe wall is a big wall, usually painted black, which allows you to absorb heat into the house without heat leaking out.

The main concern with using a big window is that while the sun's rays can come into the home and heat up the air, the glass conducts heat so well that it can all escape back through the glass.

The trombe wall solves this issue by trapping the heated air between the glass and the trombe wall, then circulating it into the house before the heat has a chance to escape through the glass.

The greenhouse approach uses similar technology to a greenhouse to keep heated air in the house. You use a large number of windows to let the sun's rays into your house, then you use a controlled timer to circulate the air within your house in a way that optimizes the heat and reduces the amount of heat that escapes through the same glass windows that let the heat in.

 Are Passive Solar Windows for You?

Passive solar windows can work for both hot and cold climates, whether there's a lot of sun or just a little bit of sun.

To determine whether or not your home qualifies for passive solar windows, talk to an environmental contractor in your area. Make sure you get several different opinions to get a definitive sense of whether or not it's worth the investment, as they can be pricey - but they can also save you a lot - especially on heating bills - in the long run.

Living Green Starts at Home

You may have gotten the impression that living green involves some sort of enormous campaign that will take all of your time and cost you lots of money traveling all over the globe. While that may be a dream of some conservationists, you can live a green lifestyle in your own home. In fact, it begins here - those who find a niche in going green in their own lifestyles may branch out and become eco-consultants or other professionals in the field of environmental conservation.

Here are some tips for implementing a green lifestyle at home.

The Kitchen

This is where you cook, use appliances, and wash hands and dishes. The kitchen may be where you eat, too. So this is a good place to start with your green lifestyle.

* Save water in the kitchen by not pre-rinsing dishes and only running the dishwasher when it's full. If you have to pre-rinse (some dishwashers just can't handle non-rinsed dishes), then do so in a sink half-full of water. Scrub and rinse with the water off, and then load the dishwasher. You've only used half a sinkful of water to pre-rinse. You can also save water in the kitchen by washing produce in a pan of water.

* Appliance use is heavy in the kitchen, from the refrigerator to the stovetop. To save energy, you can combine the cooking of foods by baking more than one thing at the same time. On the stovetop, use residual heat where you can and place pots and pans on appropriately-sized stove eyes.

If possible, use energy-efficient appliances in the kitchen. And your parents were right - don't hold the refrigerator door open!

The Bedroom

In your bedroom, you can go green in some different ways.

* Use natural bedding such as cotton sheets without a lot of heavy dyes and deep colors.

* Place air-cleaning potted plants around your bedroom to purify the air. In kids' bedrooms, potted plants can also be implemented as long as they are out of reach of young children.

The Living Room

In your main living space, you can go green by using fans to cool the room in the summer and a space heater to boost the central heat in the winter. You can also:

* Set potted plants around for cleaner air.

* Cover windows with shades or curtains to keep out hot sunshine in the summer, and open them in the winter to help warm the room.

* Make use of natural light as much as possible. Position reading chairs and couches so that window light comes from behind, over the reader's shoulder. Use small lamps with CFLs and timers.

Peripheral Rooms

In rooms that are not being used, close vents to keep down heating and cooling costs and energy use. Make sure sunshine is not heating these rooms in the summer, and apply the same principle in reverse in the winter.

These are just some simple tips that you can use to live a greener lifestyle without spending any money at all! If you have other ideas, please comment below and share your tips!

Video: How Geothermal Heating & Cooling Systems Work

This very short video explains the basics of how geothermal systems work to heat and cool your home - much more quietly, efficiently, and cheaply than any traditional home heating and cooling method. My husband and I plan to install a geothermal system in our new home, but I didn't know much about it until recently. They are a great choice for our location - more consistent and reliable than solar or wind power - and from what we understand, less prone to maintenance issues.

The systems can last up to 3 times longer than a conventional heating or cooling system - and they accomplish both objectives with one, quiet low-maintenance unit - plus providing some hot water in the summer. A 30% tax credit for purchase and installation of these systems is available in most states through 2015.
