A Ten-Dimensional Demand Response Examination

By Energy Rant No Comments
This is the third installment of this series in demand response (DR) and load management. In the first post, Curing Net Zero described why net zero is not the answer: everyone over-generates with solar or wind simultaneously, and later, everyone needs power from something else simultaneously. The second post, Demand Response Primer, gave an overview of families and specific types of load management. This time we’re looking at my scorecard of these DR resources. Here is my report card, including critical factors for each DR resource, followed by discussions of what it means. What does this poppycock mean, Jeff? Peak…

Energy Program Evaluation Tales from the Dark Side

By Energy Rant No Comments
The Energy Rant is not for the weak-kneed who prefer to live in the land of unicorns, fairy dust, and lollipops. This week is no exception.This Rant is brought to you by the recent ACEEE paper, Recent Developments in Energy Efficiency Evaluation, Measurement and Verification. Burned on the Alter of 90/10 A major objective of most evaluation contracts is to punch the 90/10 ticket. To recap, 90/10 simply means there is a 90% chance that the results of the population, if evaluated in full, will be within plus or minus 10% of the results for the sampled, studied projects. As…

Automated M&V – In Your Dreams

By Energy Rant No Comments
Last week, we explored the state of EM&V 2.0 and its considerable, to say the least, constraints. This week, we look more intensely at fallacious “automated M&V”. Automated M&V is an oversold and over-hyped concept. When something is automated, it takes inputs (data) from various sources, often hundreds of sources, with high frequency, maybe by the second or on a Hertz (many times per second) scale. Then the brains of the automated doohickey compute and translate the data into solutions or outcomes. For buildings of all types, from single family homes to large commercial and industrial facilities, automated systems are…
