The Reality of Window Replacement

they could even last for twenty if you don’t mind fog

Ugh. There it is again. A newspaper article in the home section advising you to replace your windows: “The days of painting exterior wood windows are gone. Look for low-maintenance vinyl or aluminum windows that come with a factory finish that should last for years.” Heck, they might even last for 10 whole years.

The article does not address the issue of energy savings, since the article is about low maintenance, but it is worthwhile to review the four pillars of replacement window mythology:

Energy Savings: Heat rises, it doesn’t go sideways. Insulate your roof and you have saved 80% of all the possible energy savings. Replace your windows with brick walls and you only have 20% to play with.

Oh, but they are double-glazed, you say. LIKE EVERY WINDOW DESIGNED FROM 1860 to 1928. Every Victorian and early modern building constructed in a climate that includes winter was double-glazed. We just got rid of a lot of those storm windows because we didn’t like the maintenance. Continue Reading

Window replacement numbers

October 31, 2009 Economics, Sustainability, Technology Comments (4) 1163

Pharmaceutical use in the United States has increased threefold in the last ten years, not because there has been a threefold increase in disease or diagnoses but simply because in 1999 pharmaceutical advertising was deregulated.

I don’t know the exact numbers, but window replacement has gone up dramatically in the same period, and for the same reason. Advertising.

When my wife and I bought a single-family home in 1996 I received AT LEAST three mailers and one phone call each week urging me to buy replacement windows and siding. I always responded “I don’t believe in that” which threw the telemarketers right off their script. But just as countless television ads for drugs have convinced people that they need them, today every American gets out of bed in the morning convinced that they must replace their windows.

the greenest building is the one already built

Guess who is finally saying what I and others in preservation have been saying for a while – LEED certification is not a great measure of environmental impact? Actually, it is coming from the horse’s mouth – the certifiers themselves, who found – shockingly – that many of the new green designs did not PERFORM as they were designed. From the New York Times a few days ago:

“But in its own study last year of 121 new buildings certified through 2006, the Green Building Council found that more than half — 53 percent — did not qualify for the Energy Star label and 15 percent scored below 30 in that program, meaning they used more energy per square foot than at least 70 percent of comparable buildings in the existing national stock.” Continue Reading

Chicago 7

January 28, 2009 Chicago Buildings, Technology Comments (0) 1012

Preservation Chicago released its “Chicago 7” list of endangered Chicago landmarks on Monday, and one of them was very close to my heart – the “old-fashioned” wood window. I have often spoken about the virtues of old wood windows – made of stronger, straighter, better insulating wood, and how with a little caulk and a storm window they can outperform any vinyl replacement unit. You can scroll back through the old blogs – in November I reglazed one of my windows in my 110-year old house and marveled at a project that cost a couple hours and $20, versus the hundreds it would have cost if I broke a “modern” replacement window. I even had an installation in the “Department Store” with Felicity Rich this past fall featuring old wood windows surrounded by the barrage of advertising that has made replacement windows a force to be reckoned with in the last decade. The bottom line? People replace their windows because of the advertising, not because of any value in the new windows – or any failure of the old.
