You created a regression model of your building’s energy use and now want to use its predictive capabilities. How do you go about assessing your model’s predictive power? As I mentioned in an earlier post, you want to steer away from focusing on a singular...
You can evaluate energy performance and target energy saving projects using graphics like in the case of one of our portfolio clients where we evaluated lighting control system performance looking at lighting power density (LPD) and energy use intensity (EUI). Data visualization is one of...
We use regression analysis frequently in our energy engineering analysis, but results can be less than ideal for many cases. Now with big data and the current technology of faster computing, we can use a comprehensive understanding of statistics, hypothesis testing, and principles of inference...
There is an understandable temptation to overlook highly efficient data centers when searching for energy savings. Maybe you’ve gotten your PUE down to 1.2 so why not just focus all your efforts on facilities that are performing poorly? That may be the case, but I...
