Icicles: Are our roofs too warm to retain snow?

2010 February 8

 


Sliding snow from roof after Dec. snow storm

Are you living in a unit with a mansard or a gabled roof? Then chances are that after the recent snow storm you’ll have to struggle with icicles hanging from the roof ridge and gutters. Icicles form when the snow on the roof melts and begins to trickle down. The sunny day after the storm may account for some of the melt, even if air-temperatures have been constantly below freezing. You will observe however that the snow tends to slide away in big blocks .

Some neighbors even report ‘avalanches” coming down from their roofs. How does this happen? The answer is that it is the roof that heats and melts the base layer of snow. This causes the snow cover to slide away on the slippery base just like a piece of butter would slide on a hot pan. Icicles and ice dams build up where decades of neglected insulation allow heat to escape and warm-up the slate shingles. Our roofs are simply too warm to hold the snow long enough so that it can melt without the problems we are currently having. It takes a couple of snow storms to actually  ”see” the heat -and money- loss through our roofs.

And a big THANK YOU to our personnel who have been working very hard under the severest weather.

And to all folks who helped to shake the snow from the trees in our Ravine and around the Village during that storm.

4 seconds

2010 January 25

4 seconds it would take for our Arlington Village Ravine (6 acres aprox.) to completely vanish at the pace tropical forests are currently deforested. Can you imagine the sheer violence of that? More than 250 mature trees completely gone in a blink of an eye together with the entire surrounding habitat?

As AIRE reminds in a recent post: “90 acres of rain forest are cleared every second. 20% of greenhouse emissions are due to reforestation”.  Take a look at this video, a part of Maya Lin’s (Vietnam Memorial) project: What is missing.

Recycling AND Trash on the rise in AV

2010 January 12
by takis karantonis

Last year it looked like we had achieved numbers for the books. In ‘08 we brought 179 tons of trash to the incinerator. 40% less than in ‘07. We also thought that we could show a spectacular shift from trash to recycling. To top it off, all this coincided with a substantial enhancement of single-stream recycling by our hauler. Unfortunately the success story only lasted one year. The ‘09 data give us a different picture. read more…

On Mountaintop Removal Mining

2010 January 11

I’m aware that that at least half of the  electric power needed to post this comes from coal. What I wasn’t so aware of is that I consume 3.8 tons of coal a year (or roughly 2 lbs /h), like the average you. Chances are that a good part of that coal is mined by the method known as “mountaintop removal mining”, just 270 miles SW from home: most probably here. read more…

How NOT to recycle:

Wednesday: Full to the brim!

OK it was Wednesday: Recycling Pick-Up Day. And the state of our Recycling-toters was as pictured here. Arlington Village seems to be recycling a lot. In fact, for three years in a row we have been adding more than 10% of additional recycling capacity yearly to absorb the steady growing amounts of recyclable waste.

Yet the “problem” persists. read more…

091116_ANNUALMEETINGSIGNIt’s Election Day in our small Arlington Village Republic. Our well kept but aging community needs now the guidance of us ‘The Villagers’.

The good news is that there are no decisions to take under duress. Other than many of our peer communities we are financially healthy, stable and well protected against imponderable risks. This is not a given and had to be earned with hard work over the years.

Among the most significant contributions of the current board to this community is that it proactively set the stage for discussion about the many important issues a community of our size, age and diversity has. In this year’s budget and “meet the candidates” debates we have experienced a new wave of inputs and ideas that will certainly keep our community creatively active through the next year and beyond. Also, the long way that led to the tough personnel decisions of this Fall revealed a whole agenda of pending assignments that the next Board will have to work on.

The bottom line: There are more solutions emerging from that process than problems.

Crude World cover

“Author Peter Maass has spent eight years trying to understand the politics and economy of oil production across the globe. The result is his new book, Crude World: The Violent Twilight of Oil, in which Maass tries to explain what we do for oil and what oil does to us. As you’ll hear in his interview with anchor Jeb Sharp, it’s not a pretty picture.”

Listen to a short interview with Maas about the book on PRI’s The World.
