Lighting Controls and Zero Energy Homes

An article in the September/October issue of Home Energy, "Boosting Multifamily Energy Savings Through Lighting Control Settings" (page 38), has implications beyond dramatic savings in stairwells in apartment buildings. Ostensibly the article is about proper settings for motion sensors and the…

Making the Invisible Visible: Valuing Energy Efficiency Improvements in a Real Estate Transaction

Often, when homeowners make improvements to an existing house, the most important aspects of home performance – including safety, comfort, energy efficiency, durability, and environmental impact – are literally invisible during key steps of any home sale or refinance transaction.

One result is that energy…

The Enthalpy Method

Imagine knowing the refrigerant charge was correct on a Central Heat Pump or A/C without attaching gauges!  No, I am not referring to the Lennox "Approach" calculation, which I have found to be very unreliable to predict refrigerant charge, but instead using the simple total capacity calculation with the correct tool.…

What Sustainability Is Really About

Just read a book about the work of an environmental mediator, Lucy Moore, Common Ground on Hostile Turf: Stories from an Environmental Mediator (Island Press). What I liked most about this book was that it was a series of ten stories. There…

Be a Little Like a Used Car Salesperson

Used car salesmen get a bad rap, and there are good reasons for that. But I think the home performance community can learn from them in some important ways. I say that as someone who once had a serious case of buyer’s remorse, but got over it.

When I first moved to California I was working at an independent bookstore in Berkeley, and I liked the idea of not having a car. But after a year I realized that I couldn’t get everywhere I wanted to go in a timely manner on BART (Bay…

PED's for an HVAC Technician?

An acronym for what is synonymous with all that is bad with the American Pastime, Performance Enhancing Drugs (PED's) have been proven to inflate a ballplayer's performance.  Most important in contract years, a player's performance is measured in specific statistics.  So, what if there was a pill, or cream, that an HVAC Technician or Salesperson could take to inflate their numbers.  Make them perform at the top of their field and get them the highest pay in the industry?  Would you take it?…

Checklists—The Professional's Best Friend

Want to know why air travel is still, by far, the safest way to go? Do you want to know how hospitals around the world can cut the risk of post-surgical complications and death by more than half? Do you wonder why the greatest triumphs of engineering, buildings and infrastructure, are beautiful, as well as safe and functional? The answer is checklists. I was inspired by this simple and powerful tool after reading The Checklist…

A/C a Necessity in New England?

  I remember not all too long ago, yes I am still on what I hope to be the first half of my life, that Central Air-Conditioning was a luxury.  Like the radio, then the television; next the telephone, and now the cell phone, Air-conditioning has become a necessity.  What was before Air-Conditioning?  What did the weather people (yes, politically correct here on Excess Air) say to the elderly before they would recommend "staying inside, out of the heat"?

  I remember what I used to do…

Public Art to Promote Energy Efficiency

Energy efficiency can be a tough sell. Providing detailed information about financial savings and environmental benefits doesn’t always motivate conservation. So when rational arguments don’t work, how can we influence energy behavior? Perhaps by creating an emotional response with inclusive and engaging public art installations, such as the upcoming Northeast Green Light Project.…

Modernizing the Residential Utility Disclosure Ordinance in Chicago

Back in the ‘80s, the Center for Neighborhood Technology and others helped the City of Chicago pass a residential utility disclosure ordinance that required the disclosure of heating bills when residential properties are sold or leased in the city. Why? Heating expenses constitute a significant home expense, and it’s important for consumers and Realtors to have access to this information.

Until now, complying with the ordinance could take up to two weeks: a Realtor submitted an…

Elder Star

All of us have elderly relatives or friends, but have you ever considered their energy consumption patterns? On the surface, those patterns may look little different from your own, but in fact the aging population brings new needs across the whole spectrum of health, transportation, recreation, housing, and safety. And since the over-65 cohort is a growing…

Window Improvement vs. Window Replacement

Most energy audit reports place windows very low on their list of energy improvement priorities. This isn't surprising because of the relatively high cost of replacement windows coupled with what are commonly marginal improvements in their thermal performance. Since audit reports generally prioritize energy efficiency improvement opportunities according to their cost vs. thermal benefit  (fuel savings) ratio, the energy…

Zero to 60 - Scores of Green Appraisers Hit the Streets Overnight in Colorado

Home builder Sean Smith feels like Sisyphus – the Greek mythological figure doomed for eternity to push boulders uphill only for them to crash downhill when he neared the top.  Smith’s boulder?  Higher appraisal prices for the green homes he builds in metro Denver.

Weatherization Program Brought Back to Stability for FY 2013 and 2014

I recently received the email below from a fellow supporter of the Weatherization Program regarding the current status of Federal funding for the Low Income Weatherization program.  

Relatively speaking, while I have done little in terms of personal lobbying in DC at the Federal level on Weatherization, Brad Penney deserves credit as one of the greatest leaders in personally convincing members of Congress to fund the Weatherization program during the FY2013 and 2014 - the two years…

Not getting it

I live in New England, New Hampshire, to be specific, and I just don't get the lack of seriousness about weatherization and credentials here. I'm BPI Certified Building Analyst and Envelope Specialist, have taken the Resnet Energy Smart Contractor test, have OSHA 10, lead certified renovator, the list goes on and on. Means nothing here. Area contractors insulate to be just good enough and nothing more. I can't tell you how many times that I have gone to a new construction job and have been…
