Today there are all sorts of different systems you can have installed in order to green your home and make it more energy and water efficient, but which ones give you the best bang for your buck? After all, your home is a serious financial investment and making it as energy and water efficient as possible could mean a lower overall cost of ownership and a higher resale value down the road. So to help you get the best value when it comes to greening your home, we’ve come up with the following list of clean technologies for heating and cooling your home. The first thing to do is to see if by positioning fans and capitalizing on natural ventilation, you can effectively cool your home without any major investments. If you need more than that, however (most people don’t), here are some great clean tech heating and cooling concepts.

1. Passive Solar Home Designs

One of, if not the, best ways to ensure that your home is energy and water efficient is through the use of a passive solar home design. These designs will orient and lay out the floor plan of your home in such a way that you can use the angle of the sun to both cool your home in the summer, and heat it during the winter. To get a better idea of how this works, check out this diagram and video on how passive solar heating and cooling works:

Note: This video was produced in Australia for homes in the southern hemisphere, however, the design principles will apply to all homes regardless of latitude.

2. Solar Powered A/C and Hot Water Systems

Solar energy is a fantastic way to power all of the various heating and cooling systems in your home, and while they may be a little expensive up front, they’ll save you tons of money over the life of your home. We feel that the two best ways to utilize this renewable resource is through solar powered A/C and solar hot water heaters. Both systems will drastically reduce your carbon footprint! Check out the diagrams below to get a better idea of how these systems work:

3. Fans and Ventilation Systems

Utilizing either fans or ventilation systems is a great way to make your home both comfortable and energy efficient. There are lots of options to choose from, but we feel that passive home ventilation and whole house fans are the best bang for your buck. Check out the two videos below to see how these systems work and why they’re a good investment for your home:

4. Swamp Coolers (Evaporative Cooling)

If you happen to live in an area that is both hot and dry, like the SW United States, swamp coolers are a great alternative to air conditioning. Not only do they tend to use less energy than their air conditioning counter parts, they’ll also introduce moisture to the air which will help to keep things from drying out completely. Check out this video to get a better understanding of how these systems work and why it might make sense for your home:
