The Difference Between Efficiency and Efficacy

Posted on March 02,2015 by ab3 in Ceiling fan

When I was doing research for an article on ceiling fans a while back, I noticed that fans don't have energy efficiency ratings; they have efficacy ratings. There's certainly confusion about the terminology among different sources, but since light bulbs are also described by their efficacy, I started wondering about the term. I'd just accepted it before, with a vague understanding that there was something different about how efficacy was defined. Now I know why.

Winter has barely ended in Vermont, but as I write this the forecast is for 82 degrees tomorrow. This makes me think about strategies for keeping cool in the months ahead. I’m looking forward to trying out the high-tech ceiling fans we installed in our two upstairs bedrooms. I’ll get to those fans in a minute, but first I’ll explain why I like ceiling fans so much.

A little over a decade ago when I was building a house and buying a bunch of ceiling fans, it wasn't so easy to figure out which fans were energy efficient and which weren't.

Posted on March 02,2015 by CarlSeville in Ceiling fan

I can’t count the number of times I have walked past a neighbor’s home and seen the porch ceiling fans running with no one there to appreciate them. All the fans are doing is wasting electricity and contributing a little heat to the outdoor air. I am tempted (although I have never acted on the impulse) to pull the chains and turn the fans off or leave the neighbors a note.

Keeping Cool

Posted on March 02,2015 by AlexWilson in Ceiling fan

Welcome to summer. Burlington, Vermont hit a record 97°F the other day, and my place in West Dummerston reached 93°, with high humidity. What’s the best way to stay comfortable in weather like this — assuming that you’re not using mechanical air conditioning? First, it’s important to understand that the goal isn’t really about temperature; it’s about comfort. Some very simple strategies can help you remain comfortable even with high air temperatures.

Using Ceiling Fans To Keep Cool Without AC

When I was a young backpacker traveling through India, Sri Lanka, and Thailand in the 1970s, I couldn’t afford air-conditioned hotels or restaurants. In these tropical conditions, I became quite accustomed to the benefits of Casablanca-style fans.
