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…

This week, we continue the discussion of ASHRAE Standard 211, Standard for Commercial Building Energy Audits. For ease of consuming this post, I suggest destroying 1/900,000th of a conifer by printing last week’s post, which includes a super summary of the approach, process, and contents of the three levels of energy audits in one table. The Nerd’s Arms Race One thing is certain regarding human nature: people love to complicate the hell out of things. Consider the tax code, code of federal regulations, and any part or level of government. The private sector follows similarly, maybe with different reasons. For…

It’s Halloween. Hundreds of thousands of people have to figure out a different costume because a clown plague has infected the country. While I don’t consume tabloid news, I did hear that in some cities, the clowns are getting beat up. I thought, now that isn’t a bad idea, but I wouldn’t advise that. When I was a kid, Halloween antics included dozens of mushy tomatoes and cucumbers left behind in the garden. These have the impact of water balloons, and they make a fine mess. For this post, I referenced my program booklet for ACEEE’s 2016 Summer Study on…

Not that my opinion is worth anything, but the results of Chicago’s 2014 commercial building benchmarking report are excellent. The report indicates that most of the 348 buildings that were benchmarked for the study were benchmarked using ENERGY STAR® Portfolio Manager. The cross-cutting data provided reveals interesting facts that are not expounded upon – but I will. 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…

As I mentioned in a LinkedIn post last week, this week’s Energy Rant involves an interesting article Why Homeowners Don’t Trust Energy Efficiency. The paper could also be tweaked a little and re-entitled, Why Customers Don’t Trust Energy Efficiency. Period. As usual, this brings to mind a cornucopia of spinoffs. Let’s first begin with a core theme of a rant from about a month ago. In that, I said savings from current portfolios across the country are dominated by: Incentives for trinkets like CFLs and ENERGY STAR this, that, and the other (consumer goods) and Incentives for contractors to upsell efficient…
