An article in the September/October issue of Home Energy, "Boosting Multifamily Energy Savings Through Lighting Control Settings" (page 38), has implications beyond dramatic savings in stairwells in apartment buildings. Ostensibly the article is about proper settings for motion sensors and the…Continue
All of us have elderly relatives or friends, but have you ever considered their energy consumption patterns? On the surface, those patterns may look little different from your own, but in fact the aging population brings new needs across the whole spectrum of health, transportation, recreation, housing, and safety. And since the over-65 cohort is a growing…Continue
It has come to my attention that there may be a building science-based conflict in the language of the 2012 International Residential Code (IRC) and 2012 International Energy Conservation Code (IECC).
The 2012 IECC sets the mandatory blower door tested and certified air infiltration rate at 5 ACH50 in CZ1 & 2 and an even tighter 3 ACH50 in CZ 3 and above. The problem lies in the fact that the new…Continue
As energy auditors and raters went about their business of testing homes, performing energy audits and HVAC system inspections, they discovered and reported certain “problems” to the homeowners of Texas. For example, they reported that HVAC systems were oversized, or suffering from massive duct leakage! In late 2011, The Texas Department of Licensing and Regulation (TDLR), which oversees the HVAC industry,…Continue
Most of us will agree that it’s technically feasible to build homes that consume dramatically less energy than today’s typical home. And in most locations we can build a home that draws net zero energy from the utility. But it’s economics that makes us hesitate. Specifically, it’s the value of those energy savings. Can the additional investment be offset by anticipated reductions in energy costs? It’s the same thing for retrofits of existing homes: Do the lower energy bills justify the…Continue
The Appraisal Institute’s An Introduction to Green Homes is yet another valuable tool from the Institute, paving the way for appraisers to handle green home assignments. The book, authored by long-time appraiser, REALTOR, and educator Alan Simmons in 2010 helps appraisers new to this work “know what they don’t know.” The book equips appraisers to identify green building certifications, techniques,…Continue

We all have stories about losing power in our home for several hours—or days—and many people suspect that power interruptions are becoming more frequent. They may be right; unfortunately, the utility data are so sketchy that nobody can say for certain. But declining investment in maintenance on the part of utilities, plus the increased frequency of extreme weather caused by climate change, are almost certain to keep the blackouts coming.
One response is to buy a home generator. That’s…Continue
The insurance industry, the world's largest business with $4.6 trillion in revenues, is making larger efforts to manage climate change-related risks, according to a new study published today in the journal Science.
"Weather- and climate-related insurance losses today average $50 billion a year. These losses have more than doubled each decade since the 1980s, adjusted for inflation," says the study's author Evan Mills, a scientist in Lawrence Berkeley National Laboratory…Continue

The installed price of solar photovoltaic (PV) power systems in the United States fell substantially in 2011 and through the first half of 2012, according to the latest edition of Tracking the Sun, an annual PV cost-tracking report produced by the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab).
The median installed price of residential and commercial PV systems completed in 2011 fell by roughly 11% to 14% from the year before, depending on system…Continue
What do you call a former construction worker that knows how to dance the tango? Chris Dorsi. Okay, so maybe it’s not the best punch line, but it is certainly interesting. And that’s not the only thing we learned about Dorsi in the following interview.
Currently gearing up for regional conferences to be hosted by his newly founded company Habitat X in Portland and San Francisco, Dorsi is focused on combining professional training with…Continue

This is personal. When I heard reports about rampant waste and abuse in the 2009 American Recovery and Reinvestment Act (ARRA) that turned out to be false, I thought of all the people I know who worked tirelessly to meet one goal of ARRA—to weatherize 600,000 homes before March, 2012—and it made me very angry. The men and women of the Weatherization Assistance Program (WAP) met and exceeded that goal, with minimum fraud, abuse, and waste. In fact, they reached 1-million homes weatherized…Continue
As I write this editorial in early October, the outcome of the election remains uncertain. That’s just fine, because it allows me to offer early advice to whichever candidate wins. Here are some recommendations based on my years with Home Energy.
The government plays an important role in lowering energy demand. If Americans expect the government to establish policies to regulate natural-gas fracking and power plant emissions, then it should also address energy efficiency. The…Continue
Maureen Mahle is the vice president and director of Sustainable Housing Services for Steven Winter Associates, Inc. She’s also new to the Home Energy Board of Directors. As a welcome to the board, and as an introduction to our readers, we decided to get to know Maureen a little better. Below is our conversation.
Lately we've been thinking about how readers who know nothing about Home Energy magazine, or home performance for that matter, would react if they stumbled upon our website. Yes, our magazine is aimed at home performance professionals, but what about the people that are just entering the profession? Or those that are thinking about it?
In an effort to help those individuals understand what our industry does, and how our magazine is connected, we came up with the following…Continue

The Gulyas residence in Bloomington, Indiana was one of the first homes in Indiana to receive LEED for Homes Platinum certification. Through the use of passive house techniques and additional sustainable design strategies this project easily met and surpassed the criteria for LEED.
A home energy metric measuring energy per square foot calculation and spreadsheet was created by Allison Bailes III, PhD, to help effectively measure electric and gas usage in a house.…

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
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
