When Above Average Is Not Good Enough
Let’s imagine two neighboring families on a residential block—the Joneses and the Smiths. Their homes are of comparable size and age, and both are families of four, living typical middle-class lifestyles. ...
Do you know how well your house is doing in terms of the energy it uses? Is your house operating efficiently or inefficiently? [continue reading]
A study of test methods for duct leakage revealed that there is room for improvement in this evolving field. [continue reading]
Q:Is there a standard for energy-efficient ducts? I was called to a home built in 1955 that is under a warranty from a recent sale. The customer wanted us to “fix the ducts.” ... [continue reading]
How briefly can you monitor refrigerator energy use and still get valid results? Home Energy takes another look at this timely topic. [continue reading]
If a property’s energy use were made visible, would that be sufficient incentive to convince landlords to invest in energy-efficient capital improvements? That’s the question ... [continue reading]
In the last two decades, researchers have relied increasingly on computer programs such as DOE-2 and BLAST to analyze building energy use. For example, simulations can be used to extrapolate building energy performance from limited measured energy data, or to weather normalize predicted savings in energy management or shared savings contracts. [continue reading]
Have you ever wanted to calculate how much energy a water heater would use annually in a given household? To make this task easier, Lawrence Berkeley National Laboratory (LBNL) has developed a straightforward equation that produces results close to those of simulation programs--without their baffling complexity.
