The Twelve Days of a Green Christmas – Second Day

…on the second day of Christmas my green friend gave to me…two vent fans…and a new doorbell!


My green friend gave me 8 motion sensor interior lights last year and after listening to me talk about how practical they are and the various uses for them my green friend surprised me this year with 2 bathroom vent fans!  These are not ordinary bathroom fans, they actually have motion and condensation sensors installed!   Since I am remodeling my mid-century house I have run into a few “challenges” and the bathroom electrical challenge was just another “almost” headache.

In older homes it was typical to have an opening window rather than a bath vent fan hence only one light switch and one receptacle in each bathroom.  Opening the window was to reduce humidity from the bathroom during a shower.  However when you live in a humid climate the inside humidity can almost equal the outside humidity which still promotes mold and mildew.

When I asked the electrician about installing exhaust vent fans in the two bathrooms he told me it was no problem, only money…how many times have I heard that!  I was beginning to think I was bleeding money and I would “bleed out” before the remodel was finished! He said the fan wiring would not be a problem but running the wire down the plaster walls would be where the cost would be increased. It could be an extra 1 1/2-2 hours per bathroom…at their hourly rate…yikes!

So began the research of bathroom ventilator fans on the internet.  In all my energy-efficient research I discovered an Energy Star rated fan that could be hard-wired and a “plug and play” motion (or occupancy) sensor installed. The Panasonic WhisperGreen – Select One Fan was the fan I found most fascinating.  Not only can you hard-wire the fan you can also add “plug and play” modules to suit your needs. The modules available are a night-light, a motion sensor and a condensation sensor.

In addition to these options you can actually set the cfm (cubic feet per minute) to adjust it correctly for the size of your bathroom.  Another selling point for me was the sones or noise level.  Did you know bathroom fans have sone ratings?  I always thought all of them were just loud.  Actually 1 sone is equal to the sound of a refrigerator and .5 sones is like the sound of rustling leaves.  Wow…a quiet vent fan, what a concept! The WhisperGreen fan is rated .5 sones so it should be very quiet.

The Panasonic WhisperGreen fan runs more efficiently than other fans because it is a DC motor with Smartflow® technology which means the fan speed will vary according to demand.  It is designed so that it can run all the time making it suitable for continuous whole house ventilation which would be a bonus for me as I am working to “tighten” my building envelope during my remodel and more importantly, create a healthier indoor environment.

A healthier indoor environment you wonder?  What will that do?  Briefly, if you suffer from allergies, find yourself congested or feel as though the air is stale when you are in your house and you have already eliminated toxic cleaners, you probably need better ventilation to move the indoor pollutants outside and this is done through ventilation or air exchanges.  There are many more respiratory ailments that come from pollutants in your house…maybe formaldehyde “off-gassing” from your new couch, kitchen cabinets or carpeting?  The “leakier” your house is the more Volatile Organic Compounds (VOCs) that are lurking inside.  Add the mold and mildew that the moisture in your bathrooms may harbor and there’s no wonder why you are always coughing or clearing your throat! If you would like to learn more about ventilation and how it affects your health, thoughts on remodeling your bathroom visit this page and choose an article that interests you!

So, after rattling on and on about this new-fangled bathroom ventilation fan to my green friend for months I was ecstatic to receive 2, not 1, but 2 WhisperGreen fans on the second day of a green Christmas! I can hardly wait for my electrician to install these fans!  BTW, it’s a no-brainer if you have to pay an electrician extra hours to drop a line for a switch or pay a little more and buy this fan that won’t need a wall switch! Let me know in the comments if you have one of these fans.

One thought on “The Twelve Days of a Green Christmas – Second Day

  1. We need new bath fans in our 70’s house. The old ones are so noisy and the bathroom is so dark. This article arrived in time for us to look at the Panasonic WhisperGreen fan as replacements. Thanks for the research!
