Matt

Five Years of Home Performance Testing Data from Our Clients

John Bergman

We see a lot of houses. We have a lot of data on houses. For a while now, I have been wondering whether or not I’d be able to find some meaningful relationships with this data. I am not even sure what I would use it for, but I have taken some time to compile the data and pull some numbers that I thought were interesting. More than anything, the data just shows typical values for ‘regular houses’ in the Chicagoland area.

NBC and This Old House Got It Wrong: Ice Dam Roof Damage Not Solved With More Insulation

Corbett Lunsford

This winter has been a record-breaker, but few homeowners know what they can do about it. Roof snowmelt re-freezing at the eaves (called ‘ice dams’) is a problem for many homes. It causes structural damage to roofs and walls every winter. And with more snow on the way, the immediate question is, what can a homeowner do about it?

Livin’ La Vida Verde

Steve Clark

Carbon Footprint. Sustainable. Life-cycle Analysis.  Zero impact. Eco-friendly. Green. Greenwashed. The terminology is as diverse as the people involved in what we’ve come to call “the environmental movement”. The origins of the movement are equally diverse. In his book, Blessed Unrest, Paul Hawken goes so far as to suggest the growth in environmentalism might be a biological reaction of the planet’s dominant inhabitants. Deep down, our instincts are telling us we must protect our habitat in order to survive.  It’s no longer “Save the Whales” now it’s “Save Us!”

Car Sharing is Awesome for our Company

Corbett Lunsford

corbettandgracecarsharing.jpg

We’ve recently begun using I-GO, Chicago’s non-profit car sharing service (www.igocars.org), and we love it.  Since we don’t have a conventional office where clients visit us, our transportation to the energy audits is important in several respects:

Reliability- we arrive on time, and always have a clean, working vehicle with enough gas to get us there.  I especially like the fact that if you’re in a hurry and waiting for your car to show up, the previous driver gets fined and the office will help you get a new car, and even pay for a cab to take you to it.  That was one of my biggest hangups before we got our account.

Advertising- the company’s logo, phone # and URL are all on the magnet we can stick to the outside of the car.  The magnets run us under $50 for the pair, and look great on any paint color.  Wrapping a car costs thousands of dollars.

Credibility- since we’re in the green industry, our clients are always impressed to see us walking the walk; the importance of clients who are impressed with you cannot be underestimated.

Hassle Free- this is my favorite part.  I pick the car up where it’s supposed to be, I drop it off when I’m done.  Not responsible for what happens before or after I have it, and in the middle it’s insured.  I don’t have to find and maintain relationships with honest mechanics (where are those guys?), don’t have to change oil or tires, don’t have to track mileage to write off in my taxes.

I highly recommend it, if you live in the city.  There are I-GO cars in every neighborhood, and if you’re reasonable about booking a few days in advance, you can get pretty much everything you’d have with your own vehicle, minus all the downsides.
