ECA becomes EECA (i.e. Energy > Carbon for the Enterprise)

Posted by Dalkia Solutions on Feb 8, 2011 4:46:19 AM

In 2008, when Groom Energy named and published the first report on “Enterprise Carbon Accounting” (ECA) the corporate world was just starting to track their GHG emissions as a new metric for their company’s sustainability efforts.  The financial markets hadn’t yet collapsed and EHS managers were using speadsheets to build GHG baselines and begin regular reporting to the EPA’s Climate Leaders and the Carbon Disclosure Project.  We tracked initially 40, and later 75, software vendors with GHG tracking and reporting solutions for this new market.

As Boston faces its fourth major snow storm in a month many New Englanders have sunk deep into the “dark months” blues.  And each day as I stare at Groom Energy’s snow-covered solar array I can’t dismiss some level of guilt for our environmental faux pas.

Fixing your Haunted House – how fast will Building Envelope investments return your money?

When non-engineers hear the term “building envelope” they typically think of drafty old homes with leaky windows and steam radiators overheating a bedroom while uninsulated parts of the house remain frigid.  Cash for Caulkers (the currently proposed and stalled Federal legislation) epitomized the fix for this problem – create new green jobs by arming construction teams with caulk guns for sealing old windows and doors and insulation to stuff into hollow walls, saving taxpayers money and helping our economy.

Groom Energy’s first patent – what did we learn?

Posted by proadmin on Sep 28, 2010 5:01:59 AM

Today we’re excited to announce that Groom Energy has been awarded US patent #7,771,083 for our GES Hybrid, the energy efficient lighting retrofit product we originally started to develop in 2006.
beforeOur idea came when we saw newly installed HID lighting fixtures that were perfectly fine, but whose energy consumption could be cut in half just by replacing their guts – meaning their relatively inefficient HID lamp and magnetic ballast.   Like all things in energy efficiency this had to be done a very low cost to make it interesting.

We literally banged out metal framed retrofit samples in Bob’s basement, then tinkered for several months to come up with a final design which could be used in a wide variety of fixture types (a universal design), generate strong light output (our reflector) and, most importantly, be fully installed for a low cost.

With the help of our legal team we learned how to document our invention for the USPTO noting absolutely everything around our design and all relevant prior art.  Along the way we never stopped manufacturing and delivering
