Duct Gains: Why do we hate R-8?

Ever since the adoption of the 2009 International Residential Energy Conservation Code (IECC), duct sealing efforts have been tested using the total leakage or leakage to outdoors methods.  It really is amazing how much duct gains effect the operation of your equipment and the comfort of your customer.  The missing part of "duct testing" appears to be how well the ducts are insulated.  Sure, you are required to use R-8 insulation on supply ductwork when located outside the building envelope,…

Book Review—Home Performance Diagnostics: The Guide to Advanced Testing

It (The Hitchhiker’s Guide to the Galaxy) is superior to the larger book in two important ways. First, it is somewhat cheaper than the Encyclopedia Galactica. Second, it has the words “DON’T PANIC” inscribed in large, friendly letters on its cover.

—“The Hitchhiker’s Guide to the Galaxy,” Douglas Adams

If there were any book in my library that deserves that “Don’t…

Site Survey: Windows & SHGC

  When completing your site survey for Manual J Load Calculations, significant time can (or should) be spent identifying window values.  Did you know that most windows these days come with an NFRC rating, a tag located in the window jam that you can reference on NFRC.org? This identification number can tell you important details like window coatings, u-value, light transmittance, air leakage, and solar heat gain coefficients (SHGC).  Not identifying the correct values can sway your load…

Heat Pump Break-Even COP's

How do you know if  should upgrade your air-conditioner to a heat-pump and create a dual-source application during replacement this Summer?  I personally always prefer the option of multiple fuel sources, particularly since energy prices have been all over the place during the last decade.  Fortunately, based on average energy prices, there is some simple math to figure out if an aggressive assessment should be made for a dual-source heat pump application, based on equations from ACCA's…

Energy, Faith, and the Narratives We Live By

(This post first appeared as an article in America Magazine, a Jesuit, Catholic, national weekly journal, in the May 6, 2012 issue.)

Since the beginning of the 20th century, oil has played the role of cheap labor in the U.S. economy and in economies around the world. Traditionally, we have been interested in the horsepower of our car engines, but what if we measured the energy we use in terms of human labor? To power a typical…

The Google Earth of IR Images—Q&A With Storm Duncan

By now you may have heard about drive-by energy audits. But have you heard of drive-by energy audits performed on entire cities at the same time? Say hello to the Cambridge, Massachusetts-based company, Essess. Essess (pronounced like “recess” without the “r”) has recently entered the home performance scene, and they’re making a lot of noise. In just a couple of weeks, we here at Home Energy received multiple emails from friends and partners in the industry…

Diagnosing Improper Fixed Orifice Sizes

   I have found that this topic often goes unnoticed, or can be a guessing game out there in the field.  Diagnosing improper fixed orifice sizes is actually a fairly simple, cut and dry procedure.  First, I would argue for efficiency reasons, as well as ease of proper charging, you should just field install a TXV.  Of course, when you are on the job site you don't want to spend precious time attempting to adjust refrigerant charge with the incorrect orifice. You would never be able to get…

Conventional AC is not COOL

In order to feel comfortable in the cooling season conditioned air has to be at the right air temperature AND relative humidity. Conventional AC dehumidifies when it is running but it is thermostatically controlled by air temperature only. Which means that when air temperature is reached the AC turns off and stops dehumidifying. Not a big problem if you live in an arid climate such as Pheonix but if you live in New England where the summers are very humid and not…

Correctly Sizing a Capacitor

I don't know how many times a technician has said that they installed a part based on what was on their service truck.  I have heard of technicians wasting money over-sizing contactors, cutting down air filters, and even using controlled substances to clear condensate drains!  Of course, these scenarios all get the job done, but I would argue the many reasons why not to do these.  The one thing that gets to me is when a technician doesn't verify they are installing the correct size dual run…
