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
As I recently reviewed in my “Storytelling from BECC” blog, media provides a huge opportunity for the home performance industry to make it into the mainstream. That’s why I was pleased to see recently that HGTV’s show “Property Brothers” was dolling out advice that I’ve heard more than once at industry conferences.
For those of you unfamiliar, the “Property Brothers,” also known as Drew and Jonathan…Continue

The insurance industry, the world's largest business with $4.6 trillion in revenues, is making larger efforts to manage climate change-related risks, according to a new study published today in the journal Science.
"Weather- and climate-related insurance losses today average $50 billion a year. These losses have more than doubled each decade since the 1980s, adjusted for inflation," says the study's author Evan Mills, a scientist in Lawrence Berkeley National Laboratory…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
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
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

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

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

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

When using ACCA's Manual T for register selection, there are several basic rules that are followed regarding location. Most guidelines revolve around room air circulation and stagnant air, as well as the equipment application (heating only, cooling only, or combination). Application is the largest determining factor when it comes to return air locations.
For heating only applications, a low return duct is ideal to bring back the coldest air otherwise stagnant in the room.…Continue
In the aftermath of Hurricane Sandy, people are asking themselves what they can do to lessen their reliance on centralized systems for their electricity, heat and transportation needs. As climate change brings the potential for more intense and frequent extreme weather events, the desire for alternative energy options is becoming more…Continue
The most terrified I've ever been was was the time I got called to do a home energy audit of the haunted house-as-a-system down the street. I still shudder when I think of that night. Yes, it was nighttime. The caller who hired me, a woman with a sultry voice, said that was the only…Continue
Recently, the Obama government has sanctioned relief funds for people affected by the super storm Sandy as part of its LIHEAP or Low income Home Energy Assistance Program. According to the reports, around 284,000 homes have been affected in the catastrophe. The total financial loss estimated so far amounts to $88 billion. As a…Continue
