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.

Because of fossil fuel prices… [view entry]

Last night, I attended a meeting hosted by SF Environment, a department of the city and county of San Francisco.  I was in awe and inspired by how much one city can accomplish when it comes to educating the public about energy efficiency and environmental consciousness.  Not only is San Francisco leading the domestic urban composting charge with a city-wide composting program, whereby the city mandates composting in addition to recycling, but the city is making the process of being an ecoconsumer easier and easier.

When I relocated here two months ago, I was astounded at how commonplace composting was – the city simply places compost bins throughout the city and provides them to each city resident.  In addition, SF Environment provides free compost containers for your kitchen so you… [view entry]

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 :

This is the first installment in a series of featurettes on our current interns’ summer projects.

Ilona Shmulevich in action!

At CEA, our overarching aim is to spread better energy efficiency to buildings in the city of Cambridge.   We target this goal with what can effectively be described in four steps:  First, we encourage residents to sign up for a free energy audit through MassSave.  Second, an auditor visit is scheduled and carried out wherein they perform a full assessment of a building’s energy usage, providing a list of recommended improvements.  Third, the residents learn about available rebates and decide what improvements they are willing to invest in.  Finally, a MassSave or independently-appointed contractor comes and does all the installations, leaving the residents with increased building performance… [view entry]

Cycling in Groningen, Netherlands

Recently, I had the opportunity to travel to the Netherlands and visit many different areas within the country. I landed in Amsterdam and took a train roughly 200 kilometers (125 miles) to the city of Groningen in the northern part of the country. The trip took about as long as it takes to get from one end Boston to the other via the green line (sadly I’m only half joking here). It doesn’t take long to notice the public transportation system in the small European country is as efficient any.

Stepping out in Groningen, we made our way to catch a bus to the apartment where we would stay for the next few days. Finally outside of airports and train stations, I… [view entry]

The Environmental Protection Agency recently announced updates to its Energy Star Rating requirements on televisions and cable boxes. The revisions are the first in a list of about 20 products that will receive updates to their Energy Star Rating requirements this year.

Currently, Energy Star rated televisions hold at least 70% of the Market Share. The stricter standards mean, according to the EPA, “substantial overall energy bill reduction, and carbon dioxide (CO2) emissions reductions.”

The new standards are requiring a 40% reduction in watt usage. For example, a 60 inch television currently averages about 282 watts, but the come September the same 60 inch TV will be required to use less than 108 watts to receive an Energy Star Rating. Talk about saving a… [view entry]

Solar panels are just one of many possible investments that can save businesses money in the futur

Business owners, when confronted with the decision of moving towards more sustainable practices, are sometimes weary of giving such an idea the green light. For owners, almost every decision is made with the bottom line in mind; a business that does not earn profit simply will not survive. The potential for high up front costs is enough for many owners to say “no thanks” and stick with the same practices that have been in use for years. Owners may think, “If a company is making a profit, why change anything?”

Well, when looking at a switch to sustainable business practices as an investment rather than a cost, the decision can be… [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.

When the Cambridge Energy Alliance and Coldwell Banker Agents Amy Tighe and Robin… [view entry]

Although double-hung windows are quite common in the Boston area, it seems many people do not take full advantage of their features. With proper use, windows can increase comfort, and all but eliminate the need for air conditioning; and on the odd days where lemonade and mind-over-matter won’t cut it, visit a local library or catch a movie.

How can you take full advantage of windows? If you have two, placing a fan in one to blow warm air out during the evening will pull cool air in the other, especially with a closed door. If you have only one window, a window fan with two fans blowing in opposite directions will also pull air through a space. These are rather obvious practices, but there is a no-cost technique particular to… [view entry]

CEA canvassing interns: Stephanie, Mira, Danit, Trevor, Federico, Laurence

On July 7th CEA’s six volunteers took to the streets for the first time, canvassing businesses in Inman Square, and eastward on Cambridge Street. Over the next three weeks, they would reach out to over 440 people in small local businesses—barber shops, cafes, hardware stores, book stores, florists, bars, convenience stores, restaurants, bike shops, you name it—in North Cambridge, Leslie and Porter Square, Harvard Square and Church Street, Mount Auburn and Brattle Street, Dana Hill, Bow Street, Central Square, Lafayette, Concord Ave, Huron, East Cambridge, and Broadway.

In 90+ degree heat, over previously unfamiliar terrain, and sometimes through rain storms, the teams of interns  met with over 190 business owners and discussed energy efficiency opportunities—programs and incentives from… [view entry]
