A talk by Lexington resident, Jeffrey Rhodin
Improving Energy Efficiency in Existing and Old Homes
Lexington's Cary Library Meeting Room at7:30 pm
Wednesday, December 2
Free Admission
Building new energy efficient homes is well understood and a necessary step toward sustainability. But what about the approximately 2 million existing homes in Massachusetts where most of us live? We have to start our energy improvement efforts with what we have and cope with all the restrictions that come with existing homes, some as old as 160 years. We have to choose from a constantly expanding universe of products and services that promise all sorts of benefits. What do we do first? Is it the best use of our money? Will we get the promised benefits? This talk is for us. We will cover important safety issues, basic concepts of home energy conservation, a best practice energy efficiency improvement process, and a case study that puts it all together. The goal is for you to come away with a basic understanding of how your home loses energy and a step-by-step process that allows you to make the most of your limited home improvement budget.
Jeffrey Rhodin is a resident of Lexington and founded Sustainable Energy Analytics in 2008. He is a certified HERS rater, Energystar® and IndoorAir® Plus Partner, and Lean Sigma Black Belt business improvement professional. He holds a degree in Operations Research and Industrial Engineering from Cornell University College of Engineering. He formed Sustainable Energy Analytics to help educate and provide services to builders and homeowners in Lexington and surrounding communities that maximize the return on their energy efficiency improvement budget.

OCTOBER 24, 2009
Join the Climate Action rally in
Concord's
Minuteman Park
More than 300 people gathered from 40 communities around Concord to hear speakers: Mrs. Peggy McKibben, Sen. Marc Pacheco, Rev. Dr. Jim Antal, Rep Will Brownsberger, to see a 'Polar Bear Pull for the Planet' and hear music by Jim Scott and others. Petitions were signed and colorful banners were personalized before being sent to Copenhagen. Many thanks to all who came, and to the devoted people who organized this tremendous event.
Here was the agenda for the rally
LexGWAC invites Lexington residents to join us and hundreds of area residents from more than 20 metro-west towns to the Energy Revolution Rally at the Old North Bridge in Concord at 2PM on October 24. See the GWEN website for more information.
Why is the number 350 so important? 350 is the number that leading scientists say is the safe upper limit for carbon dioxide—measured in "Parts Per Million" in our atmosphere. 350 PPM—it's the number humanity needs to get back to as soon as possible to avoid runaway climate change.
Ride your bike, carpool, walk, or rollerblade to Concord for this historic event. It's important to have our voices heard in Washington and Copenhagen this Fall.
Join others for a Revolutionary Bike Ride to the Rally in Concord.
Bike riders will gather at 12:15 PM and depart at 12:30 PM from the Lexington Green on Saturday, October 24.

Energy Savings Fair
at the Lexington Depot Building
was held on Sunday, October 4, 2009
The Energy Fair was Supported by a grant from National Grid  |
New Arrival at Cary Memorial Library!
LexGWAC has donated two Kill-A-Watt meters to the library. These devices help you see what appliances are energy efficient in your home. Simply connect your appliances to the Kill-a-Watt electricity usage monitor and it will assess how efficient they really are. The unit's large LCD display counts consumption by the kilowatt-hour, the same as your local utility. You can calculate your electrical expenses by the day, week, month, or year while also checking the quality of your power by monitoring voltage, line frequency, and power factor. Now you'll know if it's time for a new refrigerator or if that old air conditioner is saving you money.
