DIY Minisplits: Which side are you on?

 Recently, Friedrich has modeled and sold in limited markets their DIY Mini-Split Heat Pump, Breeze.  Just a few days ago, they scaled back their rollout in order to meet customer demand by limiting sales to New York and South Florida.  I am torn between…

Making Homes Cozier With a House Party

This week, Elevate Energy read two great accounts of how friends and neighbors came together to learn how to make their own homes cozier and more energy efficient. Thanks for sharing!

This homeowner wanted to improve her “leaky old ship” of a home and discovered an energy loss culprit.

I survived my first ACI

I did it. I survived my first conference in this industry, the 2014 ACI National Home Performance conference in Detroit.



When I joined The Energy Conservatory in June 2013 I was brand new to this industry. Before TEC I didn’t even know this industry existed, let alone what a blower door was. To help me learn all of this building science geekiness I decided to take BPI’s Building Science Principles course and exam. I read the book twice, and then took the exam, which I passed! I…

Everyone Knows You Except for Your Electric Utility

Netflix, you were right. I liked Downton Abbey. And thanks, Amazon I do want to read Michael Lewis’ new book. I still can’t figure out how Google knows I have a new dog.

Even if at times it feels a bit eerie, such ‘consumer-of-one’ marketing is a convenience many of us have come to appreciate. And it’s an approach now embraced by most major retailers.

The exception? You’ve guessed it: the ever-old fashioned electric utility.

But…

Interview with Van Jones: Rebuilding the Dream in Detroit, Part 1

Van Jones delivered the opening plenary keynote speech for ACI's 2014 National Home Performance Conference in Detroit last week.  I've been aware of Van's work since he started the Green Collar Job Corps program at the Ella Baker Center in Oakland, Calif., back in 2007.  Van was the main advocate for the Green Jobs Act that was signed into law by Pres. George W. Bush in that year. 

Under the Obama…

New Air Tightness Record in Ontario (Dare I say Canada?)

It happened again yesterday: a new record (tell me if you know of a tighter house in Ontario if not Canada!) for air tightness was broken in Oakville by Certified Passive House Consultant (CPHC) Ed Marion of Passive House Ontario.

And this was just a pre-drywall test, so it can only get better from here.…

The House of Mystery

Sometimes we forget how complicated a house is. Building scientists know all about a house’s complexity because, even with help from supercomputers, they still can’t reliably simulate many of the processes taking place, let alone model the whole house. Perhaps the biggest challenge is that the darn thing can’t keep still. Cycles with different periods impose their wills on the structure and equipment in not entirely predictable ways. The seasons impose annual cycles for the sun and average…

5 Things New Energy Efficiency HVAC Contractors Need to Know

1. Do not sell on Price! Use 'Simple Payback'

The price of High-efficient equipment will undoubtedly cost more money up front, compared to the minimum efficiency systems. Taking into account existing repair bills, utility bills, installation, and equipment costs, a high-efficient furnace, boiler, or heat pump will cost the homeowner less over the estimated 10-15 years of operation. When completing the 'Simple Payback' calculation, the high-efficient heating system in New England will… Continue

A call to Builders and Architects: Does the Homeowner Know You’re a Blowerdoor Virgin?

When setting out to build an efficient house, the elephant in the room is air tightness. Industry is resisting mandated air tightness testing if thresholds are introduced meanwhile building codes are ratcheting up efficiency on all fronts except air tightness. Having debunked the myth that “a house needs to breath” its becoming painfully obvious to any building scientist that the lowest hanging fruit on the efficiency tree isn’t geothermal but simply producing a more air tight…

Energy Upgrade California—Up Close and Personal



Our furnace is approaching 25 years old and we have no cooling capabilities, so my wife Michele and I are looking into buying some new equipment before the temperature climbs this summer. I am especially interested in installing a mini-split heat pump, which would allow us to get rid of the ductwork and…
