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&...
The American Society for Testing and Materials (ASTM) has decided to improve protocols for two popular test methods for testing duct leakage in residences--the "blower door subtraction" technique and the "flow hood" technique. [continue reading]
Many of us in the energy conservation business are "techno-junkies." [continue reading]
With the use of blower doors, weatherization programs have improved cost-effectiveness by prioritizing air sealing work, developing effective inspection procedures for determining if work was done properly, and assessing the impact of air sealing on indoor air quality and moisture problems.
