Tankless- expensive, high maintenance, high failure rates, high install costs, limited flow rates, poor winter performance, long payback.
Hybrid Electric- too tall, need surrounding space for heat exchange, poor durability, noisy, may need condensate pump.
Solar- requires southern exposure, cold & cloudy days: poor performance, very long payback, high install costs
The good old Storage Tank water heater- electric is OK, fast…Continue
Promises of savings without tracking DRIVES ME NUTS. People are being harmed and we don't have any idea how big the harm is. Comprehensive Home Performance really takes off once you connect tracking results because now you can offer a thing very rare.
You can offer TRUTH. You can offer PROOF that what you say will happen, will happen. Delivering the "5th
How do we create pressure for Utilities to open up their data so tracking can be automated?…Continue
GUILTY! Once upon a time, I would have scoffed at mechanical engineers and contractors if they'd ask me, as the design architect, for a bigger room to put the HVAC (heating and air conditioning) equipment in.
"Are you crazy? And give up valuable storage space???"
They might have also ask me for dropped soffits and vertical chases to run the ductwork through. To which I would reply:
"What?!?! That's not consistent with my innovative and beautiful design! The…Continue
In 2012 we decided it was time to replace our 27-year old contractor grade double paned aluminum widows. Some of the seals had failed. Some of the window were leaking (water).
We planned to replace 19 windows initially and ended up replacing 21 in total. 11 of which were single-hung 3-0x6-0 that we replaced with double hung windows. Three had arched eye-brows and had to remain single-hung.
From my online research I was…Continue
The inability to heat one’s home is known as ‘fuel poverty’ and it is at an all time high across the UK. Around 8,000 people die each year because of it and there are urgent calls for more energy efficiency to prevent fuel poverty…Continue
In November 2012 I started replacing all CFL and Incandescent lighting in the home with new LED bulbs. At our local 'big box' home improvement store I purchased several (35) LED bulbs and began making the switch to LEDs. Over the past several years most of our incandescent lights had been replaced with CFLs. I was not happy with the performance of the CFLs both in terms of light quality and life of the bulb. It seems like every other month I was…Continue
During the past 12 months (2011/2012) we have completed several energy efficiency and other projects in our home in Plano, Texas.

Under Roof 2560 sq. ft.
Home faces Southeast. All rooms have ceilings above 8' with ceiling treatments (vaulted, boxed, splayed,). Home built with 24 contractor-grade windows mostly 3-0x6-0. Home…Continue

I am sure I am not the first to write about this, but it doesn't change expectations of homeowners or trade employers. Why is it that millionaire ball players can be successful batting .300? A pitcher can have thirty starts, win 20 games and could be named for the Cy Young? Or that a successful quarterback can throw 20 touchdowns and 10 interceptions? The reason: they are much better than their peers.
Imagine, as an HVAC Tech, you got the diagnosis correct one-third of the…Continue

We know energy efficiency can save the world, but can it save a marriage?
Leave it to the New York State Energy Research and Development Authority (NYSERDA) to take on that question. The agency is known for its vanguard energy research. But it is one thing to produce papers on topics like ‘Air Bypass in Vertical Stack Water Source Heat Pumps’ and another to delve into what a cold room can do to a new marriage.
That’s the premise behind Irreconcilable Temperatures, a…Continue
The installed price of solar photovoltaic (PV) power systems in the United States fell substantially in 2011 and through the first half of 2012, according to the latest edition of Tracking the Sun, an annual PV cost-tracking report produced by the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab).
The median installed price of residential and commercial PV systems completed in 2011 fell by roughly 11% to 14% from the year before, depending on system…Continue
When I attend a conference I can always tell which sessions I find most inspirational by the amount of notes I take. While attending the annual Behavior Energy and Climate Change (BECC) conference on Monday of this past week in Sacramento, the note test proved itself once again. Hands down, I found the most inspiration from the afternoon Spotlight Panel titled “Hollywood, Media and Messaging.”
To be fair, I was excited about…Continue

What do you call a former construction worker that knows how to dance the tango? Chris Dorsi. Okay, so maybe it’s not the best punch line, but it is certainly interesting. And that’s not the only thing we learned about Dorsi in the following interview.
Currently gearing up for regional conferences to be hosted by his newly founded company Habitat X in Portland and San Francisco, Dorsi is focused on combining professional training with…Continue

How much electricity is need to roast a Thankgiving turkey & the rest of the holiday cooking extravaganza?
Monitoring baseline data from the Phased Deep Retrofit project being done by Florida Solar Energy Center for U.S. Department of Energy allows us to answer that question. Thanksgiving cooking in our 30 home, all electric sample averaged 2.76 kWh, 2.03 kWh more than it did on the Thursday before Thanksgiving (0.73 kWh)
Note that in the…
High initial costs can discourage homeowners from making large investments in energy improvements such as new heating equipment or insulation. Our Community Energy Services (CES) residential program tries to remove this barrier by helping identify available rebates as well as offering financing options such as low interest loans. Homeowners who complete a CES home visit qualify for a…Continue

Two years ago Software Advice predicted that electricians would be one of the best-suited construction trades to capitalize on the growth of green construction. It appears that prediction is coming true. Since 2005, the green construction industry has grown from close to three billion dollar industry to one worth roughly $48 billion.…Continue
