From Boston to Austin real estate there’s a new trend.  Rooftop gardens, or green roofs, are popping up everywhere. These gardens add life and color to gloomy, industrial looking cities and drab roofs.

Rooftop gardens improve air quality, create local food sources, delay water runoff, and bring color to a dull roof.  They also help insulate buildings and reduce electricity and gas costs, which is  particularly beneficial for people who live in very hot or cold areas. According to GreenRoofs.com, green roofs allow buildings to retain 30% more heat in the winter than ordinary roofs. Green roofs also reflect light and heat, which may help buildings stay cooler in the summer. The insulation from rooftop gardens also helps block out noises from outside.

There are many different kinds of green… [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 :

On June 1st, three tornadoes touched down in western Massachusetts during a surprise series of storms, leaving a wake of destruction and confusion. Massachusetts, not known for tornadoes, is now beginning to rethink state policies surrounding severe weather preparation and emergency response.

ReBuild Western Massachusetts, a program developed by the Massachusetts Department of Energy Resources (DOER) and administered in partnership with the Massachusetts Clean Energy Center (MassCEC), was announced on August 4th and will distribute more than $8 million to help building owners affected by the tornadoes rebuild using energy efficiency practices and renewable energy technologies. Eligible participants include those who can document damage caused by the June 1 storms, and who own buildings in communities in Hampden and Worcester Counties, including: Agawam, Westfield,… [view entry]

New England property owners are beginning to understand the benefits of a “green” building: higher occupancy rates, higher rental rates and lower utility costs, to name a few. But working with just the “sticks and bricks” of a building can make it only “light green.”

To go deeper, a building manager must engage the community that occupies the building: the tenants. A building and its tenants are two interconnected systems that must work in-tandem to produce eco-efficiency. Even if a building is built to green standards, it will not perform in a deep green manner if the occupants are not actively participating in green practices. Ultimately, it is the tenants who recycle,… [view entry]

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]

This past Friday, I attended a workshop lead by Dr. Doug McKenzie-Mohr entitled “An Introduction to Community-Based Social Marketing: Fostering Sustainable Behavior.”  As someone who’s personally very intrigued by the oftentimes overlooked (and dare I say critical) link between our everyday psychology and environmental sustainability, I was eager to attend. What I learned was both enlightening and somewhat anticipated.

In brief, humans, at least the populations Dr. McKenzie-Mohr has studied, tend to default to the easiest common denominator of behavior when it comes to environmentalism.  Of course, this isn’t to say there aren’t outlier personalities who go above and beyond the “green” call, but overall, unless regulated to do so, or cajoled by neighbors or friends, most people will resort to the path of… [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]

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]

Debating on whether or not to get a real or fake Christmas tree this year?  Well, if you haven’t already, then think twice: a recent article by the New York Times reported that unless you keep your fake tree for 20 years or more, it’s more environmentally conscientious to purchase a real tree. It sounds counterintuitive – aren’t Christmas tree farms agriculturally damaging and don’t we need more trees intact to act as carbon sinks? Turns out, it might not be that clear cut.

Using calculations that included greenhouse gas emissions, use of resources and human health impacts, a Montreal-based environmental consulting firm found that the annual carbon emissions associated with using a real tree every year were one-third of those created by an artificial tree over a standard six-year lifespan.… [view entry]

What would you do if your doorbell rang on Halloween and instead of saying “trick or treat!” your visitors handed you a new, curly-cue light bulb (or two)? This year’s Halloween saw an event that was a brand new take on the usual compact fluorescent light bulb canvasses that the CEA hosts.  We are thrilled to see that this creative event went off without a hitch, and that it has set a great precedent for following years!

Please see below for the post featured on the Green Medford blog:

A group of us from Green Medford and Fletcher Green (a Tufts graduate student group) trolled the streets around the Columbus School last night–Halloween evening–handing out bags of treats to delighted and laughing residents at 84 addresses. People… [view entry]
