Cooling System Temperature Control- No Savings

By Energy Efficiency, Energy Rant 5 Comments
Let’s skip the energy supply side this week and talk about thermostats used for cooling. Let’s broaden the discussion to include both programmable thermostats and “smart” or “learning” thermostats. The Nest falls into the latter group. Speaking for the Nest, which I have controlling my heating and cooling, it will learn user patterns by when, and to what level, the user changes temperature setpoints. It also secretly learns the users’ occupancy patterns by keeping an infrared eye on them. For instance, if the thermostat is in a heavy traffic area, it will learn to expect a lot of traffic, and…

Utility Reference RIP – Thank You Litigious Loser

By Energy Efficiency, Energy Rant, Utility Stuff No Comments
In case you are new to this blog, or somehow haven't noticed, I tread where no mortals tread, through the valley of the shadow of death.  I discuss the all important bowels of the industry, and this week I have the crown jewel of a very unfortunate reality that is counterproductive and really harmful to the industry.  In fact, it is not only harmful to the industry, it is crippling the entire society.  Whoa!  Ok, what is it?  It is political correctness and our society of hyper-litigious losers.  We can't find or use utility references - people who will give…

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…

Energy Efficient Technologies that Suck [Energy]

By Energy Efficiency, Energy Rant One Comment
Sometimes I wonder. No, sometimes I’m amazed how certain energy efficient technologies have fooled the industry and the public for years, possibly even decades, into a false sense and blind acceptance for energy savings.  Want to see two technologies that are flexible, cheap, easy to use, and effective at saving energy?  That’s it – the first two wonder technologies shown. Instead, there are universally accepted incentives and “savings” that would make a charlatan blush.  Exhibit A: the occupancy sensor for lighting control.As I ranted in Oh Behave, I have found that this technology wastes energy by training occupants to leave…

Bling not Required

By Energy Efficiency, Energy Rant No Comments
Rant fans are getting a break this week.  This post exemplifies a smashing success in energy efficiency and is a bit of a spinoff on capitalizing energy efficiency as I discussed in Facility Management, Taliban Style and Better than Doritos. The story begins with a board meeting for the Iowa Association for Energy Efficiency.  BTW, this is the least expensive, far and away, greatest-benefit-per-dollar-invested energy efficiency organization in the country. The board meeting was at an apartment complex, Sun Prairie, in West Des Moines or thereabouts.  As I pulled in with 134F heat at 9:30 AM, I was thinking, “Is…

Chester the Energy Advisor

By Energy Efficiency, Energy Rant, Utility Stuff No Comments
We are from the government and we are here to help.  Kaboom!  That would be my door slamming in their collective faces. A number of years ago, and just recently I was reminded of it again, the federal government was selling it’s handouts to citizens – actually advertising free stuff, food or services are common.  This is perverted.  We do not have people starving in the streets of this country and this is a lock because if we did, the media would be all over it like flies on watermelon rinds.  Quite the opposite: we have a type 2 diabetes…

Energy Savings Rubbish

By Energy Efficiency, Energy Rant No Comments
The best thing about working in our industry is the potential for continuous learning, unlike nearly any other field.  There are enough things to learn about buildings, manufacturing, systems, how they are built, as in design, construction and commissioning to fill a 45 year engineering career.  One always finds something “new” even in old buildings – bizarre design concepts for example.  Have you ever seen how Fig Newtons are made?  It isn’t easy. Engineers might think, what else is there to programs besides determining energy savings, simple payback and possibly ROI?  About 75%, if not, more.  There are market assessments,…

EE V IRS

By Energy Efficiency, Government, Investments, Tax Stuff, Utility Stuff 2 Comments
Warning: I am not a CPA or tax attorney, and I do not have 63 years available to determine for myself that all contents of this rant are correct. A couple years ago I wrote an Energy Brief about the need for life cycle cost analysis to make the right decisions for selecting the best option for an energy project.  Since that time, we haven’t exactly been living up to this ideal, in large part because we’ve been doing a lot of work for profit-driven enterprises. Life cycle cost analysis for non-profits is pretty easy.  It includes first cost, borrowing…

Cheater Pumpkin Eater

By Energy Efficiency, Government, Utility Stuff No Comments
Many states have opt-out provisions for major consumers of energy so these consumers do not have to pay into EE programs.  The reasoning typically goes something like this: They are major users of energy so they naturally are going to cut energy cost to increase profit; they can take care of themselves They shouldn’t have to provide outside subsidies to these programs They don’t participate in the programs so why should they have to pay in The facts are these concessions are required to get EE laws (bills) through legislatures and/or governors. Consider that typical opt-out regulations require that these…

Oh Behave

By Energy Efficiency 8 Comments
I swear we were introduced to the food pyramid when I was in grade school but a little web searching gives me just a couple – the one from 1992 and the new and improved one in 2005.The 1992 edition is shown in Figure 1.  If you can’t read it, good. The 2005 vertical colorful edition with the stickman and skewers for hands and feet is shown in Figure 2. For 2011 (Figure 3), the USDA has switched to this brilliant “plate” that looks like a pie chart developed by a group of kindergarteners employed by Microsoft, except I really…
