ENERGY STAR Gets it Right – Owners Complain

By Energy Rant No Comments
Show me the money, Jerry! That is what I have to say about building energy performance. I don’t care for bling and doohickeys. What is the bottom line at the meter? I surmise that ENERGY STAR Portfolio Manager was conceived and developed with the best of intentions to score and rank buildings, at the meter level, for energy performance considering vast factors including building type, hours of use, climate zone and so on. However, as noted in the Lake Wobegon post a few years ago, not all, but most buildings are above average . In that case, the average building…

Benchmarking Flaws and Best Practices; Pot Growers Discover Sunshine

By Energy Rant No Comments
The City of Chicago recently issued its annual report on commercial building benchmarking. I pick on Chicago because (1) its upper-Midwest location has a climate like that of many of our readers, and (2) because it uses ENERGY STAR® Portfolio Manager, which I addressed several times before. With Portfolio Manager, everybody seems to get a trophy, and results are troublesome to me. Also, for reference, I published this post last fall, pointing out the failures of energy codes to move the energy intensity needle. Using data from the Energy Information Administration, that post showed that buildings built in the past…

The first thing is rather stunning.  The median ENERGY STAR Portfolio Manager score for 348 buildings, accounting for 260 million square feet of building space, was/is 76.  By definition, the median score of all buildings in the Portfolio Manager database is 50.  The…

Energy Studies – Leading and Planning, Not Chasing

By Energy Efficiency, Energy Rant No Comments
Surprisingly, to me that is, it has been a long time since I wrote, or ranted, about the virtues and ignorance of those who think energy studies – audits, feasibility studies, assessments, - are a waste of time and money.  This is your lucky day because I have a large, multi-year evaluation of a NYSERDA audit program that proves my point. The classic Neanderthal mindset is that doing energy studies for end users is a waste of money as they simply serve as shelf and desk clutter, and get tossed when the owner of the study moves to a different…
