Dave Conna replied to Curt Kinder's discussion Vampire load surprise - garage door openers
"Curt, Ted, Robert:I've been following your threads and feel compelled to weigh in again. Robert: I agree entirely with your assessment of the situation - the consequences are dire and we are collectively in denial (to varying degrees) about…"

Dave Conna replied to Curt Kinder's discussion Vampire load suprise - garage door openers
"Hey Curt and Robert: Let's not go overboard here. Curt: garage door openers are relative luxuries and the world did survive without them before but, Robert, they are hardly the worst environmental insult that most of us engage in. I also heat…"

Dave Conna replied to Curt Kinder's discussion Vampire load suprise - garage door openers
"We have to work on society's values changing if we are going to avoid careening into the abyss.  Energy efficiency give us breathing room - but only if we have seen the light and decided to change our ways. Frankly I am not encouraged that…"

Dave Conna replied to Curt Kinder's discussion Vampire load suprise - garage door openers
"Yes, I sell EE the same way - I know my clients will buy into the idea if their lighting costs 50% less to operate and is BETTER at doing the job but will not be excited if they saved 60% but the lighting sucks. That having been said, I agree…"

Dave Conna replied to Curt Kinder's discussion Vampire load suprise - garage door openers
"So we do agree: as far as I am concerned your comments are accurate and objective and a compassionate person SHOULD feel shame at them. My point is that I fear there are a lot of people who will not respond to shame - even when it is…"

Dave Conna replied to Curt Kinder's discussion Vampire load suprise - garage door openers
"I agree with you, Robert. But shaming people - even when it is probably deserved - rarely works, unless it is done by religion - then it seems to work too well! I try a shame/encouragement strategy as follows: My grandparents lived through the…"

"I guess they don't call those garage door openers "Phantoms" for nothing ;)"

Dave Conna replied to Curt Kinder's discussion Vampire load suprise - garage door openers
"Thanks for the heads up on the garage door opener phantom load, Curt - I never thought of that one.  I just measured one of my Python 2 garage door openers (made by Overhead Door) and it uses 4.6 to 4.8 watts on standby (measured with my…"

Dave Conna commented on Elisa Wood's blog post Three jokers in the energy deck
"In order for our political leaders to get it, we need to talk their language - and understand why they don't talk ours: 1) The word conservation has bad connotations to many - they think of cold houses, slower cars and deprivation.  (Never…"

Dave Conna replied to Dennis McCarthy's discussion Lighting audits as a subset of the energy audits.
"Good to know, Dennis.   But it still begs the questions I asked about the lumen output seeming much too high for the wattage.  Have you checked the numbers - either qualitatively or quantitatively?   Also you did not reply to my…"

Dave Conna replied to Dennis McCarthy's discussion Lighting audits as a subset of the energy audits.
"Dennis:   I have to wonder if you are "limit[ing] your endorsements" because you are using Lights of America products, which I criticized in a previous post.  I write this because the spec you described is identical to an LOA…"

Dave Conna replied to Dennis McCarthy's discussion Lighting audits as a subset of the energy audits.
"Dennis,   While I appreciate your enthusiasm, I have to agree with Fm - for now the economics of LED lighting for many applications just isn't there yet.  And I am replacing 24 hour lighting and using 20 cents per kWh in my calcs -…"
Mar 24, 2011
Dave Conna replied to Dennis McCarthy's discussion Lighting audits as a subset of the energy audits.
"Dennis,   LEDs are advancing at an astounding rate but so far they have been great for directional applications (reflectors, exit sign, traffic lights).   I don't know what the time horizon is for affordable, high lumen output…"

Dave Conna replied to Dennis McCarthy's discussion Lighting audits as a subset of the energy audits.
"Fm,   The lighting systems I design and use controls on are for large multifamily building common areas - so they are basically light commercial spaces with very long (24/7) run times, which makes the paybacks sweet.   I love the motion…"

Dave Conna replied to Dennis McCarthy's discussion Lighting audits as a subset of the energy audits.
"Dennis,   I am not in complete agreement with you about CFLs being garbage: some manufacturers (like Lights of America) make real garbage but I have some early electronic CFLs (from Osram) that are in my bathroom and (thus get abusive on/off…"

Dave Conna replied to Dennis McCarthy's discussion Lighting audits as a subset of the energy audits.
"Yes, for the average single family home where lights only operate 3 ro 4 hours per day on average, the more expensive items do not make sense.  In multifamily facilities there are a lot of lights that operate for 24  hours per day - the…"
