Putting Mercury in CFLs in Perspective

This is an updated version of the post that originally appeared here.



I'm a fan of CFLs, but I can understand how the small amount of mercury in them can worry some. If you're worried about the tiny bit of mercury in CFLs, I can't tell you one way or another how to decide for your home, all I can do is give you the facts that are available, and let you make your own decision.… Continue

Breaking light bulb myths

I have to agree with the Tea Party; the US government should not choose the light bulbs I use in my home.  And fortunately, it does not.

Yet that’s the spin being pushed by those who want to roll back federal lighting performance standards. An odd mythology is developing around the standards.

Opponents claim that the…

Redefining the Term "Mobile Home"

 

The most energy efficient home is one that's already built. Keeping a home out of a landfill saves all the materials in the house, as well as all the energy used to create the materials—the building's embodied energy. And historic homes preserve a slice of culture that would otherwise be lost forever. And what's better than keeping one 100-year-old house out of the landfill? Keeping two 100-year-old houses out of the…

Houses Don't Use Energy: People Do

As my good friend Rana Belshe says.  Let's not forget that the people who live in houses are the ones who are in charge of how the house loses and gains energy and how the appliances and HVAC use energy.  People are the key and heart of gettin' it done!

Energy Tax Credits for 2011: What's Available

Thanks to the federal tax bill signed into law in December, there are still energy tax credits available for 2011. That's the good news. The not-so-good news is that the amounts available in 2011 have been reduced for certain improvements. From 2009 through 2010, homeowners were rewarded with a 30% tax credit for making their homes more energy efficient ($1500 maximum credit). For 2011, homeowners will receive only a 10% tax credit for home energy efficiency improvements ($500 maximum credit).… Continue

Building Science Proven by the Bug Man



A buddy of mine, Dennis, that’s an exterminator called me the other day while I was standing in Home Depot.  “Jon, I’ve got a problem and I need some of your building science expertise.” The problem he was having was being caused by some granules he had put down to repel some flying squirrels.  The granules…

How the Heck Does a Heat Pump Get Heat from Cold?!

It's been cold out this winter, so I've been talking a lot about heat. Invariably when I talk to people about how heat pumps can keep your home warm in winter, they get a look of bewilderment on their faces and ask how that's possible. No one ever tells me that they're confused about how a…

ACI's Energy Upgrade California

ACI's Energy Upgrade California, held January 10-11 in Los Angeles, presented a pretty good picture of how the Energy Upgrade California program will roll out across California. Currently an investor-owned utility (IOU) pilot program, it offers modest rebates for whole house improvements. There are a variety of rules and regulations, and paperwork, and processes that were all laid out pretty clearly at the conference. In addition, the local municipalities talked about their related programs and… Continue

Staging and Phasing Efficiency

A few weeks ago I was interviewed on the“Green, Better, Best” radio show. I was asked in advance to provide a "top ten” list of energy saving tips for the home. I've been asked this many times before, and I always feel like I’m being asked to discover the “easy” button. When it comes to energy generation and efficiency, there are no silver bullets that will take down the beast, but with good planning…

New Label for Things Made from Wind Energy

I am composing this blog post on a computer that was likely assembled in a factory that runs on electricity made from coal. The aluminum for the case and other parts of the computer probably came from a smelter powered by natural gas. The electricity powering the computer here in California could come from a combination… Continue

Code is a four letter word

 

From my experience in the field I would say that code is the most overused misunderstood word. Early in my construction career I heard this word thrown around. It was and is referenced often with true meaning and good advice.  

However it has also been used as a conversation ending to a dispute from the Ivory Tower “Thou shalt not doubt in me for I am the reference of thy Code and cannot be denied”. It is from these sources that I have issue. I have found that often times…

The New Rules of Home Improvement

Many homeowners are beginning to recognize the higher standards that are being demanded from home improvement contractors.The new rules of certification, accreditation and independent verification have complemented well the old ways of selecting a contractor so that the two establish a benchmark that bodes well for the professional perception of the industry. It is not a coincidence that in 2010 credentialing and training organizations have achieved their highest…

Extending Energy Efficiency Financing To Underserved Households

Lawrence Berkeley National Laboratory just released a new Policy Brief on NYSERDA’s Green Jobs-Green New York Program.  It focuses on their recent effort to extend EE financing to underserved households. Prior to the launch of GJGNY, NYSERDA used Fannie Mae Energy Loans to provide program participants with access to financing to overcome the upfront cost barrier of energy upgrades.  The underwriting standards for this unsecured loan product, including a minimum decision credit score of 640, …
