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.

Search for the Solar Grail

Hello to new EnergySagers -

I’m located in Massachusetts and I thought my recent experiences looking into solar PV for my house might be helpful for folks.

First off, I should say that I’m pretty lucky to have an unobstructed south-facing roof. I’ve been thinking about solar for a while, and watching prices go down, so a couple of months ago I started asking people who had installed solar PV panels if they could recommend companies. I found two through word of mouth and then I found three more via EnergySage.com.

I was definitely interested in the “social” benefits of cutting back on fossil-fuel generated electricity, but what really… [view entry]

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]

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]

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]

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]
