Vital to the operation of the refrigeration cycle, superheat must be maintained and stable to protect the compressor. We all know that the heart of the system cannot compress liquid (slug) without bad things happening. This would represent low/no superheat. But, did you know high superheat can cause valve and compressor problems as well? No matter the reason for attaching your gauges to the system, you must check the superheat, in the air-conditioning cycle.…Continue
I was reviewing an article in Home Energy by Steve Mann that came out in the January/February issue (“DOE’s Challenge Home,” p. 6). He wrote on the latest iteration of DOE’s Challenge Home Program. Steve points out, in his usual insightful and articulate way, what he sees as the strengths and weakness of this program. I hope you’ve read it, or will read it. Send us your comments by email, or on the Home Energy website.
Reading Steve’s article made me think, “Wow, do…Continue
The January/February 2014 issue of Home Energy magazine officially kicks off our 30th year in print. In commemoration of our 30 years we will be reprinting some of our earliest articles. We hope that these articles are both entertaining and informative.
Ode to Efficiency
The cellulose was blown in the attic with care
In hopes a cold winter soon would be there
The leaks and the cracks and the holes are all foamed
Plugging up spaces…

It seems like every one and their brother has a Night Before Christmas parody. Mine appeared in fragments on Twitter a short while ago, during an odd moment of creative inspiration, and would’ve been completely lost to Twistory, had it not been for my good friend Sean Lintow Sr.…Continue
Twas the night before Christmas, when all through the house
Not a cool draft was freezing, to wake up the mouse.
The owner called a contractor with knowledge so rare,
In hopes that great comfort soon would be there.
The children were nestled all snug in their bed,
With nary a cough or a cold in their heads.
And Momma in her Kerchief and I in my cap
Had just settled down for a long winters nap.
When from my neighbor there a rose such a…Continue
On November 1, 2013, Home Energy began its 30th year in existence. The story telling will begin officially in our January/February 2014 issue, when, along with a lot of new content and some new features, we reprise an article from our first issue—on the energy efficient use of water beds! Unofficially, the storytelling has already begun.
Home Energy began in an office at Lawrence Berkeley National Laboratory and a few years ago we moved our shop down the hill to West…Continue

ACI hosted its Regional Home Performance Conference (#acica13) in La Jolla, Calif. last month for approximately 200 attendees and 23 exhibitors. This event comes at a critical juncture as the second phase of Energy Upgrade California (the first was during the ARRA Recovery Act period) is currently ramped up by the Regional Area Networks, the new configuration of…Continue

Compact fluorescent lamps (CFLs) are one of the most popular energy-saving options because they emit as much light as a traditional bulb but use less energy. As simple as it may be to change a light bulb, there are some safety precautions that must be adhered to in order for the CFL to be an effective, safe, environmentally friendly option. Here are a few things you need to know when…Continue

So I met a man from SDG&E the other day. It was a chance meeting as he was explaining to a customer how he was being charged for electricity. He was very informed and I picked his brain with a few question trying not to be to intrusive. He explained some of the new changes in charges that will be forth coming. Flat rates for electricity in California
A little background.
The great Enron Crisis of 2000 caused sweeping changes in rates and how we as consumers we are charged…Continue
We had the great pleasure of air leakage testing a new off-grid, high performance house last week. It was the most air tight building we’d ever tested!

Which residential water heating technology is best for meeting electricity savings goals? It will depend if the goal is reducing total consumption or lowering peak demand.

While preparing for Home Energy’s 30th anniversary, we leafed through some of the earliest issues. Today’s issues are slick compared to those early years. It was amateur hour then because an untrained staff researched and wrote articles, prepared artwork, edited, typeset, proofed, and much more. Still, the topics have not changed much and—sadly—some of the editorials from the 1980s…Continue

Home Energy authors and Cornell College of Human Ecology professors Joe Laquatra and Mark Pierce and colleagues provide important information for anyone interested in energy efficient and healthy homes. In this issue they cover the presence of dangerous levels of radon in natural gas extracted through…Continue
As the price of land edges up, the practice of tucking a garage under the second floor of a house is common practice, but is it good practice? The bedroom above the garage has earned the moniker of “The Bonus Room” as it tends to be the most troublesome room in the house with the most comfort complaints from home owners.

The market share of condensing boilers, sometimes called high efficiency boilers, has increased dramatically over the last several years, thanks in part to utility programs that provide rebates. Unfortunately, many of these newly installed condensing boilers…Continue
