THE GREEN HOME
Five Beginners’ Steps to a Greener Home

A RECENT Amazon.com search for “green home” pulled up more than 15,000 book titles. Who has time to read them all? So this week, The Green Home tracked down Eric Corey Freed, the author of “Green Building & Remodeling for Dummies,” and asked him to distill this growing cottage industry of green advice into five must-do steps.

What’s the first and most important thing every green-minded dweller should do?

Look at all the vampire loads that are sucking energy even when you’re not using them.

You mean like the toaster with a digital clock and the cellphone charger?

Yes. Anything with a ready light. Collectively, vampire loads cost Americans about $3 billion a year. The biggest culprits are stereos, DVRs, game systems and plasma TVs. Simply unplug them when they’re not in use. Or purchase smart power strips, which cost about $25 and shut off automatically.

What’s the second step for making our homes greener?

Take an empty two-liter soda bottle, wash it out, fill it with water, screw the lid on tightly and set it into your toilet tank, as far away from the flapper valve as possible. This prevents two liters of water from being used every time you flush.

Will it leave enough water for a proper flush?

A new low-flow toilet uses 1.6 gallons per flush. Older toilets go up to seven gallons a flush. Two liters is only half a gallon, so there’s still plenty of water left for most bathroom visits. Besides, you can always flush twice for those rare occasions when it’s truly needed.

Moving right along. Your third recommendation?

Install an ultra-low-flow shower head. A 1992 federal law requires all shower heads to be “low flow,” which means 2.5 gallons shoot out every minute it’s on. Switching to ultra-low-flow means you could go anywhere from two gallons all the way down to half a gallon a minute.

But how’s the water pressure?

Ultra-low-flow shower heads mix outside room air into the water so the pressure is surprisingly good. The technology has really advanced. The old stigma of not having enough pressure — do you remember the old “Seinfeld” episode where Kramer couldn’t get enough water, so he switched to an elephant hose? — that doesn’t really apply.

So far, these projects sound really manageable. What’s No. 4?

Install a gray-water system that collects soapy water and diverts it to the toilet. Instead of clean water, you flush with soapy water. WaterSaver Technologies (watersavertech.com) makes AQUS, a $300 system that installs under the sink.

Is there a simpler way to capture and use gray water?

Actually, there is. It’s a toilet-topped sink called SinkPositive (sinkpositive.com). You replace the toilet’s heavy porcelain lid with this sink basin, which has a built-in faucet. When you flush, fresh water comes out of the faucet and you wash your hands with it. The soapy water collects in the toilet tank for the next flush.

Forgive me for asking, but how does the SinkPositive look?

Like something you might find in a dentist’s office.

What’s the final step people should take?

This is probably the most important: replace old thermostats with a programmable one. It’s kind of like a TiVo of thermostats. It lets you turn the heat down when you sleep and back up before you wake. It can also tell the difference between Monday and Friday, so you can turn down the heat while you’re at work. A good one costs about $20, and saves about $180 a year on energy bills.

So we don’t need to go home and install solar panels or put down bamboo flooring tonight? That’s a relief.

These five projects aren’t sexy, but everybody can do them.
