Utilities worry about a lot of things, such as keeping the lights on, earning a return for investors, and making regulators and customers happy with their service.
Now there is a new worry: How can they protect customers from what one utility refers to as “mental fatigue?”
In this particular case, the utility raises the issue as it prepares to invite homeowners and small businesses to select from among new and possibly complicated rate options made available because of smart…Continue

Heat flows out of your home in two ways, transmission and air leakage. Transmission and air leakage occur through all surfaces of the home - walls, floor, roof, windows and doors.
The amount of heat transfer depends on two factors: thermal resistance and surface area. Thermal resistance has to do with the quality and quantity of the material in the walls, floor, roof, windows, and…Continue

So, I was getting ready for my morning bike ride to the coast and decided I needed some calories. Part of my choice was some tortillas. I placed them in the toaster oven and went about my morning. This included drinking my morning coffee and checking my email.
Mmm what is that smell? I had inadvertently put the…Continue
Please read the article and catch the screen cast at the end of the article.
Earlier in the week, I spoke about construction flaws and how builders have a tendency to build energy waste right into the structure of a home. The contractors really don't mean too, we all understand that, but , never-the-less, poor construction design, short cut methods, and lack…Continue
Americans tend to beat themselves up over their imperfections. We eat too much, watch too much TV and owe China too much money. Despite all of our sloth, we can feel good about one area: our progress saving energy.
A report issued this week by the Institute for Electric Efficiency found that we saved enough electricity to power almost 10 million homes in 2010 (about 112 MWh). That’s 21…Continue
So you have decided you want to earn or become a LEED AP. There is just one small issue, unless you have or are working on a LEED project, just how are you supposed to gain the experience & show documented involvement on a project registered or certified for LEED? (AKA a letter of attestation) As some well know, finding or being able to gain the needed project experience can be a rare opportunity. Fortunately though, the chances for many looking in have an opportunity through a…Continue

Construction flaws waste energy, reduce comfort, and encourage building deterioration. A little knowledge about construction methods can help you locate and correct these flaws. Let's face it, homes were not created equal, homes are the result of a hundred hands belonging to fifty different people that will never live in the house, but, never-the-less, have great influence…Continue

I don’t believe this is an industry specific issue but we do seem to have an excess of acronyms.
For example we have RESNET, HERS, BPI, LEED, CSG, ACCI, ANSI, OSHA, WISHA, OMG, & LMAO!
Confused yet? No – then let’s try these on for size… ACH50, ACHNAT, SIPS, DMHP, HP, WH, HVAC, CFM, ELA, SLA and IECC, MEC, ASHRAE but don’t forget NYC!
BTW can you name EPA, HERC, OSB, PVC, ABS, BD, DB, MDF, MDO, SEER, HSPF, HRV’s, ERV’s, DOE, NGBS, BIA, PV, UV, UVA, UVL, DHW, IAQ,…Continue

Perhaps the greatest challenge to promoting energy efficiency is that you can’t see it. People understand electricity produced from a PV collector on the roof, and a kWh meter can easily report precisely how much energy was generated. But with more-efficient products, savings cannot be directly measured; instead, one must reckon the difference between a real and a hypothetical situation. This complexity creates a lingering uncertainty whether the promised savings did or did not actually…Continue

2011 was a challenging year for the operators of the Texas electricity grid. 2012, however, isn’t likely to be any easier. This according to ERCOT who holds the responsibility of insuring the reliability of the Texas grid. There are a large number of power plants that are scheduled to be decommissioned over the…Continue
Can anyone convince me that this picture shows anything other than the fact that the ventilation provided here is effective only in the first five inches down from the ridge? And yes, there is continuous soffit venting that is baffled and open to the…Continue
Got a phone call from a Son today, he was down at the local Mall looking to exchange a shirt he got for Christmas. This is one of those times when I wish that cell phones would just go away. Why do we need to be in constant touch with everybody all the time?
"Yes son, I bought the shirt there and I don't know why I cut the tag off and I don't know what happened to the…Continue
I have a big bay window like 10'-11' wide and 4' high. At the winter time this window brings cold into the room. It is not convenient to weatherize this window from inside. I thought to cover it with plastic sheeting from outside. I have a brick walls around this window outside. I bought a frost king weatherseal clear tape for outdoor but it lasted only one week and refused to hold longer. I tried a gray duct tape but it lasted only one day and gave up. I looked what other people are using…Continue
