Better Measurements, Better Models: Advances in Measuring and Predicting Thermal Performance
As 2-D and 3-D modeling to predict building performance becomes more widespread, we need to consider what data are feeding those models. At this point, modeling software has become quite sophisticated, and many users don&...
Duct leakage continues to be one of the biggest home performance problems, so duct sealing retrofits are in steady demand. Here at Ecotope and Delta-T, we've discovered a way for advanced duct sealers to speed up their diagnostics. [continue reading]
Blower doors, pressure tests, and other diagnostic tools are useful for assessing home performance before and after weatherization. [continue reading]
In the past two decades, many energy analysis software packages have appeared on the market. Most of these have been time-consuming, complicated to use, or unable to handle a sufficient number of variables. [continue reading]
The first data loggers were human. When labor was cheap, students and others were hired to sit next to wattmeters and record the reading every 15 minutes. Data loss occurred for various reasons, such as boredom. [continue reading]
The blower door as we know and love it today springs from technology first used in Sweden in 1977, where it was actually a blower window. [continue reading]
