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
We've created a blog post at AlabamaWISE.com comparing home energy efficiency to auto energy efficiency over time, using photos to help people visualize the prevailing technology when homes were built: http://www.alabamawise.org/whats-your-home-mpg-rating/
If you haven't heard of the PowerSaver Grant, you're in for a treat. This bonus to the FHA 203k renovation loan is meant to help home buyers - or homeowners who want to refinance and remodel - go green, save green and get green. Yes, the cliches flow freely, don't they?
With the PowerSaver Grant,…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
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…

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.
I recently published an article on Green ID's home energy blog and in the DOE's Home Energy Pros on an energy efficiency product, giving a review of its effectiveness and ideal situations. The review was not a negative one but I did point out some weak areas of the product. The review made it on Home Energy Pros featured blogs and caught the eyes of the CEO of the product. He was obviously concerned about any negative press because he contacted me through…Continue

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
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
“Weatherization Drives New Technology and the Home Performance Industry,” hosted by NASCSP, brought a full house of movers and shakers to the White House to demonstrate WAP’s technical innovations, leadership in the home performance industry, and role as a go-to partner for utility and other partnership projects. Brad Penney, on behalf of NASCSP, opened the event and thanked the…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

My idea of a blog isn't so much writing knowledgeably on a topic for other people to benefit from, but a personal journal of my professional experiences. I've been an Energy Auditor for almost two years and so I plan to blog about all the things I do wrong and don't know. Doesn't that sound like fun? Yeah, and my blog is SO not public. :-)

A Shout out to Creative Marketers
I don’t know about you but I am sick of hearing about Black Friday and Cyber Monday and am glad these are over. What I am more interested in is how companies contributed to recent events such as Small Business Saturday and Giving Tuesday.
I wrote my …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

Aeroseal is a product that seals small leaks in the ductwork. No attic work is required by the crew to work the equipment. It is monitored by a computer program that tells when the pressure of the ductwork is low enough that most of the leakage has been sealed.
The plus side to Aeroseal is that:
1. It is able to reach inaccessible parts if the attic such as flat roofs.
2. No attic work has to be done.
Every homeowner and business owner needs to pay their electric bills but that doesn’t mean that they necessarily enjoy doing so. This is especially true when it seems as if the rates keep rising at certain times of the year. Some people look for ways to reduce their bills, whether by limiting their use of electricity or by switching companies but before doing either of these things, it is important to understand what affects the energy prices in the first place. Prices will vary slightly…Continue
