We are starting to roll out heat pump water heaters in the Pacific Northwest (Oregon, Washington, Idaho, Montana, and Wyoming). One of the concerns we have in colder climates is the recovery time when the ambient air is cold. The lower the ambient temperature the less effective the heat pump water heater will be in generating hot water causing issues in households with more people, more bathrooms, and in colder months if the heat pump water heater is installed in garages or…Continue
The latest cover (right) of Home Energy features a photo of a man named Scott Willingham. Scott is pictured while working as part of the Veterans Green Jobs program, which trains veterans to work in the Weatherization Assistance Program (WAP), as well as other green jobs.
That cover photo leads readers to a…Continue

The chart below recently caught my attention (1). It shows the changes in prices over time of residential “utilities,” that is, electricity, natural gas, water and sewage, and telephones. My attention normally goes directly to the familiar energy utilities, electricity and natural gas. But wait! Water and sewage prices—they are typically billed together—have outstripped all others. The prices for water and sewage have been climbing so rapidly that water-related expenditures now exceed those…Continue
Below is a post I published on calculating a home energy use by region using a tool my utility (Georgia Power) provided (made by Apogee). It's a nice tool to show homeowners if their utility provides something similar. It could help you validate how improvements to the home can help save energy.
Everyone is seeking the elusive killer app that will revolutionize energy. Most expect it to be a high tech gadget, or new form of generation or a way to finally store mass quantities of electricity.
Not anthropologist Susan Mazur-Stommen. She’s looking in a completely different place: inside our heads, or more specifically inside the heads of those who live in the Deep South.
Mazur-Stommen, who is the director of behavior and human dimensions for the American Council for an…Continue
Recently my 13 yr old Carrier A/C devolved a leak and I chose to replace the system rather than track down the leak and repair the coil. I had been reading about doing manual J calculations and how contractors are scared to death to undersize. I had been talking to co-workers about this and it's an uphill battle getting them to think different than 1 ton per 500sq ft. So I decided to take confidence in correct sizing and "put my money where my mouth is" and install a 2 ton sized…Continue
Home Energy Pros,
Has anyone used a lead generation service that they have had success with?
What are your general thoughts about lead generation?
At Mapawatt.com, we think that linking educated consumers with home energy pros is a much needed service. Of course there is Angie's list, but that is a paid service and I dont think it's that strong in Home Energy services.
Mechanical ventilation of your home is a good idea. That means a fan running 24 hours a day 365 days a year. It provides a means of reducing indoor air pollutants and improving IAQ. It’s good for you and your whole family. We have a cute saying “dilution is the solution to indoor air pollution”
But aren’t you supposed to show me ways to save money and use less electricity? I don’t get it
Recently the California Energy Commission (CEC) put window film on the fast track to get it into the new building code—to be effective in 2014. As the first state in the nation to place window film in the next building code, California has officially recognized window film as a legitimate, cost-effective energy saver.
This change in thinking is due to recent reports and studies that show just how effective window film, a thin polymer adhered to the inside of glass, is. One such study…Continue

This summer, the Innovation Exchange is thrilled to host Alice H. from Paris, France! Alice is a project manager on energy retrofit of residential buildings at the research division of an energy utility company in France. She’s volunteering at CEE for a few weeks to discover the nice people of Minneapolis and also learn about energy efficiency in American buildings. So far, she’s really enjoying her stay!…

Sleeping on the front porch after a hot summer day was a straight out necessity. The upstairs of the 1940’s farm house had turned into a sauna and sleeping in the upstairs bedrooms was not possible. Even after the sun went down, the upstairs seemed to get hotter. Let's look at some ways to cool a house without air conditioning?
Now that I spend time trying to figure out how a home can be more energy efficient, I think back to those hot summer days and wonder two…Continue
The Monday night plenary speaker at the 2012 American Council for an Energy Efficient Economy (ACEEE) Summer Study of Energy Efficiency in Buildings, held every two years in beautiful Asilomar, California, was Jon Wellinghoff, Chairman of the Federal Energy Regulatory Commission (FERC). Wellinghoff described his coming to FERC in 2006 as a border crossing from the world of energy efficiency—according to Steve Nadel, before joining FERC, Chairman Wellinghoff attended 12 Summer Studies—to the…Continue

What’s happening in Japan? Quite a lot according to the 2012 Summer Study on Energy Efficiency in Buildings, Tuesday night plenary speaker, Andrew DeWit, Professor in the School of Policy Studies at Rikkyo University. Professor DeWit described nothing less than a battle taking place upon the ruins of the Fukushima power plants, between sustainability and crushing debt; same-old same-old, and the new green economy.
DeWit described the “Hashimoto Phenomenon”. Hashimoto is an Osaka-based…Continue

We know that what a political candidate says during a campaign often differs from what the eventual office-holder does. We also know that candidates choose their words carefully to give themselves wiggle room for modifications in course.
So we listen for innuendo and subtleties when candidates talk about our special interests. What kind of qualifying language do they use? Are they truly against X, Y and Z, or only under special circumstances?
Below are some quotes on energy…Continue
Another American Council for an Energy Efficient Economy (ACEEE) Summer Study on Energy Efficiency in Buildings has come and gone from the beautiful Asilomar Conference Center in Pacific Grove, California. But the reverberations of the talks, discussions, and connections made will reverberate until the…Continue

Carol Markell, our sales manager extraordinaire, always appreciated the people in this industry because she found them to be conscientious, hardworking, and generally a kind and socially engaged community who walked their talk. To honor her memory, we (the staff at Home Energy) asked ourselves how we walked our own talk. Following is what we discovered about each other:
Kate, our production manager, reported that every night she turns off all her electronics…Continue

In August 2011, Affordable Housing Associates (AHA) celebrated the completion of Harmon Gardens, a multifamily apartment building that provides shelter and supportive services for 15 transition-age youth, ages 18–24, which are homeless or at risk of homelessness.
Designed by HKIT Architects, and constructed by Midstate Construction Company, Harmon Gardens aims to be a model for sustainable design. Located in Berkeley, California, the development utilizes existing infrastructure and PV…Continue

When I think about real time power usage data, I am thinking about data that is being made available that very second. Data that is being reported in real time is like watching a football game live. You know that the running back just added 10 yards on to his total because you just saw the run on the T.V. That's real time.
It is being reported that the Green Button program being offered by many power companies allows customers with a Smart Meter to see their power usage in real time,…Continue
