Fans in the attic? The idea at first may sound odd. We usually think of fans as blowing somewhere in our home where we can feel their effects, like hanging from ceilings or mounted in windows. Few people spend more time in their attic than they absolutely must, so it seems useless to install fans there.

However, attic fans can form an important part of maintaining the overall efficiency of your air conditioning system. If you’ve taken all the steps you can to keep your HVAC system working its best (regular maintenance, duct cleaning, changing the filter, proper insulation), attic fans will take you a step beyond. We’ll explain why putting in attic fans will benefit you.

Attics are both heat traps and heat escape routes. You can use insulation to stop heat from escaping in winter, but what about summer, when heat gathers in the attic and creates excessively high temperatures that will seep into other parts of your home? (Go up into your attic on a hot day and see what it’s like. It can be miserable. You don’t want any of that to get to rooms you actually use.) To stop summer attic heat, you’ll need attic fans.

Attic fans should be wired to a thermostat that will turn the fan on based on the temperature. This saves energy since you won’t have to keep the fan on constantly or continually check on it. The movement of air in the attic will lower the high temperature.

The first benefit is the most obvious: your home will not get as hot during the summer. On average, the temperature in the attic will decrease 50 degrees with a fan, which means a drop of 10 degrees in your house.

This not only translates into comfort, it also means savings on your energy bills. A cooler house requires less work from an air conditioner to cool it. You’ll spend less, and your air conditioner will not receive extra stress that will lead to repairs and possibly an early replacement.

Attic fans will also extend the life of your roof. Rising moisture in your home will get into the roof, eventually creating mold in the insulation and the roof material. In winter, the freezing moisture can be extremely damaging. Attic fans move moisture away and keep it from settling.

Two years ago I was riding my bicycle in the lanes near my workshop – it’s a very good way to keep fit. But that winter afternoon it was dark and my lights had failed, and I fell off into a ditch full of icy cold cow-poop. As I got to my feet, the idea of cycling in a warm, dry, well-lit environment seemed irresistibly attractive. Almost immediately when I got home I started sketching the Star-Turn bike. – Bruce Munro, his website. Here’s one more photo of the magnificent Star-Turn:

Every home uses energy in one form or the other; and in most instances, this electricity comes from the power grid. Statistics indicate that almost 50% of a home’s energy is used by its HVAC systems while about 12% goes into the lighting. Most property owners presume that all the energy-efficiency upgrades happen through various home improvement upgrades such as replacement of wooden windows and doors with energy-efficient 2 or 3-paned vinyl windows etc.

While these changes do add to the energy-efficiency of your home, there are a number of electrical systems and maintenance upgrades that can significantly improve your energy usage, such as:

It’s not uncommon for us to occasionally leave the lights on when we leave a room. Or there may be times when we leave the deck, patio or poolscapes lights on all night with the security aspect in view. These types of habits can become a significant energy drain, but there is a way to curb that. We can install motion sensor lighting in the exterior spaces of your home; the lights will get switched on only when the sensor picks up any movement within its range. This helps you save energy without compromising on the safety factor in any way.

Most people don’t realise that their local electrician can help them when they are upgrading to energy efficient appliances. The fact of the matter is that simply replacing older appliances with ones that have high energy star ratings may not always help them reduce their electricity bills.

When you upgrade the appliances in your home such as air-conditioners, dryers, dishwashers and washing machines etc., these appliances tend to need a higher wattage compared to the older ones; this means the upgrade may actually strain the circuit breakers and your electrical system. It’s important to get a skilled electrician to come and check whether the existing wiring and system is built to bear the higher electrical loads that the newer, advanced systems need.

Inadequate or improper insulation is one more major sources of energy loss on most properties. And if you are considering a home renovation/remodelling/extension project, it’s a good idea to upgrade the insulation in your house as well.

Today, many property owners are quite committed to opting for eco-friendly alternatives to many materials and systems. If you feel you want to reduce your carbon footprint, you might want to consider installing solar panels in your home. This can significantly reduce your reliance on grid power.

Upgrading appliances or making major electrical upgrades can sometimes prove to be an expensive proposition and may not fit into everyone’s budget. This is why it’s important to know how to make some smaller changes that will also add to your home’s energy-efficiency. Some things that can make a big difference are:

Technology giant Google made its start as a search engine, subsequently branching into email, cloud storage, advertising and so much more. Now the company from Mountain View is surging forward with a new application, promising to tell consumers if their roofs are suitable for installing solar panels. The program, called Project Sunroof, works in conjunction with Google Maps to analyze your roof's size, orientation and shade levels to tell you at a glance how much solar energy you could get from it. Read on to learn more about how this convenient software works and how it can help you.

A Mix Between a Solar Electrician and a Search Engine

The program is simple to use – all you have to do is enter your address, and Google does the rest. According to the company, the program analyzes all of the following to determine how much sunlight you can soak up:

The program also provides information about what tax credits are available in your area as well as the local rules regarding selling solar energy back to the utility company when your panels are producing more than you need. It then spits out a recommended installation size, which you can modify based on how much electricity you actually consume according to your average electricity bill.

Pay Nothing and Start Saving Today

Google's entry into the solar market comes at a time when the options for solar are expanding, including the ability to lease panels from solar companies and enjoy savings on your utility bills while paying nothing for the installation and setup. A good setup can last for 30 years or more, with little to no maintenance from an electrician once the installation is completed.

Of course, solar isn't for everybody, since many roofs might be too shaded or otherwise not suitable, and some states still don't have good solar policies. Therefore, Project Sunroof can be a good place to get started to see if your house is a prospect before you even call a solar electrician. Currently, the program is working on a trial basis in Boston, San Francisco and Fresno, with more cities sure to be on the way.

Don't Forget About Human Experts Just Yet

Of course, even a technology company as powerful and ubiquitous as Google can't fully substitute for an experienced solar technician when it comes to analyzing how you can benefit from panels. If a Google query indicates that your home is a good candidate, have a qualified electrician or solar expert make the final determination and help you decide if solar panels are right for you.
