This winter photo shows brightness where the most heat is escaping this home.

Cambridge! It’s finally here: a chance to vividly see the cool or warm air leaving your drafty home, without having to pay hefty fees to a thermal photographer. Thanks to the Thermal Imaging Project on which HEET has partnered with Sagewell Inc., Cambridge homeowners can request thermal (infrared) images of the outsides of their homes.

The images are taken with car-mounted cameras similar to those used for Google Maps street view, and taken on a “first come, first served” basis – with highest priority given to locations with highest demand.  With the slight air of a Groupon deal, Sagewell has asked for 400 requests from Cambridge before they will release our thermal images for free.

What is common between the beach, the pool , cold showers and lemonades ?

Water !

Even though water seems like it is an unlimited resource, is in reality a limited resource because there are no known new sources of water. Americans consume about 150 gallons of water every day, which is twice the world average. Water needs energy to be transported and has a huge environmental impact. More water required means more dams and reservoirs, which in turn means more damage to marine habitat.

Check out National Geographic’s water footprint calculator to discover how you use water and calculate your footprint.

Here are things you can do to conserve water and do your part to save the environment :

What does ‘green building’ mean?  How can principles of sustainability be implemented in building design and construction and be certified as such?  These were questions that the U.S. Green Building Council (www.usgbc.org) dealt with when they rolled out their first Leadership in Energy and Environmental Design (“LEED”) guidelines in the 1990s.  Although LEED has received criticism for not incorporating measured building performance in its accreditation service, their guidelines have evolved over the years and are regarded as the leader in the world of green building certification [1].  Energy 2.0 contributor John Bolduc reports that here in Cambridge–one of the nation’s most accomplished cities in sustainable practices–64 buildings have either been registered with LEED or accredited.

But for all the usefulness a green building certification system brings with it, it still doesn’t get at the need for sustainable developments on a slightly larger scale–that… [view entry]

Dresden, a city of 220,000 in the eastern part of Germany, was the target of Allied firebombing in World War II that largely destroyed the city.  The wonderful skyline of towers built by the Saxon kings was restored and the downtown area is vibrant.   While the eastern part of Germany has suffered from emigration to other regions, Dresden has been growing modestly.

The City is bisected by the Elbe River and has a number of tributaries that flow into it.  In 2002, Dresden saw a major flood that inundated the city center, including the central railway station.  Over 1 billion Euros in damage was inflicted by the floods and some lives were lost.  The flooding was the result of the Elbe River overtopping its banks, rising groundwater, and the Weisseritz River defying… [view entry]

The Altstadt

Cars are prominent in Freiburg, but there is a different relationship between people, bicycles, transit and cars compared to home.  Cars defer to pedestrians, bicyclists, and transit as they negotiate the city streets.  Bicyclists and pedestrians move around each other fluidly.  There is also a higher level of convenience in using non-automobile travel modes.

Freiburg has made the Altstadt – the old core of the city – a car-free zone.  Only residents who live within the zone and service vehicles can drive in.  Pedestrians, cyclists, and the tram are freer to move.   Fraziska Breyer of the City government told us that when the car-free zone was proposed, businesses were very concerned that shoppers would shun the center.  But the decision has instead made the… [view entry]

Kaiser Joseph Strasse, in Freiburg Center

I’m on a personal study tour of Germany and Holland to see what German and Dutch cities are doing about reducing greenhouse gas emissions and adapting to climate change.  The tour is organized by ICLEI-Local Governments for Sustainability, an organization that the City of Cambridge has been a member of since 1999.  Our tour leader, Jade Jackson, is leading our group of 4 Canadians and 2 Americans through Freiburg and Dresden Germany, and then on to Bonn to attend the ICLEI Climate Resilient Communities conference.  We will end up in Rotterdam in The Netherlands.  I thought I would try to share what I see and learn along the way.  I hope you find it useful and interesting.

In Cambridge, we often… [view entry]

Cross-posted from the Sustainable Business Leader Program blog.

On May 23rd the Sustainable Business Leader Program, Cambridge Local First, and the Cambridge Energy Alliance hosted a new kind of business sustainability workshop:  a business-to-business conversation featuring the Cambridge Brewing Company, a handful of business-centered sustainability services, and a score of small business representatives curious about their own green options.

By having many of the players in the room at the same time, small Cambridge businesses were able to comfortably learn how they could make their businesses more environmentally friendly while saving valuable natural resources and money.

The workshop featured a presentation by Phil “Brewdaddy” Bannatyne, owner of Cambridge Brewing Company, who highlighted the steps that his business took to “go green,” including much… [view entry]

Residents of Cambridge, MA were introduced to a new opportunity on February 8th, 2011. Energy efficiency is on the minds of renters, condominium owners, and homeowners alike as the environmental, financial, and physical benefits become more prominently appreciated. Usually when energy efficiency information is available, it is more general and further discussion with specific professionals is suggested, since the process of making home energy efficiency improvements is tailored to unique home and ownership characteristics and often entails several detailed levels of complexity. On February 8th, those professionals were brought together in one place for an evening of sequential enlightenment for curious attendees, with an added bonus of networking amongst their industry peers and less-assumed partners, Green real estate agents.

The Gulf Oil Spill has been the event at the top of everyone’s mind for many weeks now, almost to the point of our adapting to the initially shocking concept. The images that have surfaced have been heartrending enough, though, that the shock factor hasn’t been allowed to completely fade. Predictions of the results to come in the next weeks and months are concerning to say the least, and the estimate of how much has been leaking each day continues to rise. BP comes up with a new method to “fix” the problem every few weeks, each seeming promising with a side-serving of bad news.  Effects on humans are starting to surface, some gruesome news and some simply tragic projections. With all of… [view entry]
