Hey, Hey, Hey, Buggy Whip Bites the Dust

By Energy Rant One Comment
A couple weeks ago in Driving Ms. Free Rider Daisy, I wrote about free-riding new construction and lighting programs – that to make a difference we need a change in outdated rules for energy efficiency programs. One reader responded, “Good points that have been around since the word negawatt. Any program ideas, besides stop paying for LEDs, that helps us obtain negawatts beyond the free rider ones?” It is your lucky day. Another Buggy Whip to Walk the Plank You can spend a fortune on personal trainers, dieticians, doctors, and a personal chef to lose weight. Or you can spend…

Energy Management System – Not Another Litter Box

By Energy Efficiency, Energy Rant No Comments
In recent weeks, I have been spending considerable time examining energy management system projects for energy efficiency program evaluation on the east coast.  My conclusion is this: blown opportunity abounds. The program documentation for one particular project drips with evidence that the project is a free rider, which means the project would have happened anyway in absence of the program.  How do I reach this conclusion?  First, the calculation methodology could work if the user knew what they were doing, but it is clear they either don’t know what they are doing or don’t care to get it right –…

Fly High and Jump!

By Energy Efficiency, Energy Rant, Investments, Utility Stuff One Comment
Natural gas utilities tend to howl about making EE goals because it is much more difficult to capture savings for natural gas than it is for electricity.  With one giant exception, lighting, this isn’t really true and I do not agree.  Lighting retrofit/replacement is indeed easy for a number of reasons: Utility DSM product managers and account managers understand it. Customers understand it. Lighting upgrades improve lighting brightness and color rendering. Some level of investigative analytical study is NOT required. With the exception of early T8 electronic ballast technologies, maintenance is reduced, at minimum because the customer has new equipment…

Taking on Parmenides

By Energy Efficiency, Energy Rant One Comment
We do a LOT of energy efficiency program evaluation and measurement and verification work all over the country; make that North America.  Program evaluation consists primarily of process evaluation (process) and impact evaluation (impact).  Our work is almost entirely in the impact side and I know just enough to talk dangerously about process. Impact is the analysis of what energy savings are really attributable to the program.  This includes verifying the physical installation and determining the actual savings using some sort of engineering analysis.  This actual savings is known as gross savings in the business.  It also includes determining whether…

ACEEE Summer Camp 2010

Well here I am again – a prisoner in the penitentiary that is the Minneapolis Airport.  Northwest Airlines now part of Delta Delta Delta can I help ya, help ya, help ya (YAH! – you can get me the hell out of here) can’t fly through a swarm of mosquitoes without being delayed.  This is the burnt crust on the dessert that was otherwise a great week.  And as usual, I can’t help but sit here and ignore the MASSIVE amount of energy gobbled up by this place.  It’s a bowl of hot soup outside.  It is about 68F inside…
