Our service territory is the Roaring Fork Valley, from Glenwood Springs to Aspen. It also includes Marble and Redstone.

The W9 form (aka the “Request for Taxpayer Identification Number and Certification”) is an IRS form, but not one you send to the IRS. That might sound confusing, but it’s actually pretty straightforward. You typically get one from an organization like CORE that will be paying you. When you submit a W9, it keeps you in good graces with Uncle Sam and helps CORE process rebates quickly and accurately. Without it, we can’t pay you.

In a nutshell, we help you save energy and cut carbon emissions. One of the ways we do this is by offering the community energy assessments, advising and funding for qualified projects. (with links) If you’d like to hear more, check us out. 

It will take less than three weeks.

Yes! You just need to make arrangements directly with the analyst.

Your application must be submitted within six months of completing a project or final invoicing. Like any organization, we have budgets and accounting systems that we have to stay true to, so we can’t keep our books open indefinitely. Submitting your paperwork promptly helps us both.

Windows don’t pass the “cost-effectiveness test” for reducing carbon emissions and we want you to get the most bang for your buck!

Yes! You will find utility rebates here (links).

CORE provides rebates for these measures (link), and if your idea contributes to a project with a Home Energy Rating System (HERS) index of <50, you might qualify for a net-zero grant (link).

We’re lucky to have lots of local talent in the Roaring Fork Valley. You will find a list of trusted CORE contractors here (link).

You need to have an energy assessments every five years or after a major remodel, whichever comes first.

If your home is not connected to the grid, or is in Glenwood Springs and not on the Glenwood Springs Electric grid, your project does not qualify for CORE rebates.

The path to zero is all about maximizing efficiency. Sealing air leaks before improving insulation ensures you get the most out of your energy upgrades.

Once you fill out this form (link), you are on the path to zero and may submit multiple invoices with one W9.

AFUE (annual fuel utilization efficiency) is the measurement of how efficiently a gas furnace or boiler will operate over an entire heating season. AFUE is measured as a percentage; the higher the better!

COP (coefficient of performance) is the measurement of how efficiently a heating or cooling will operate at a single outdoor temperature condition. A COP in the high single digits is fantastic.

HSPF (heating seasonal performance factor) is the measurement of how efficiently heat pumps will operate in their heating mode over an entire heating season. A HSPF between 7 – 8 is typical for a good rating for an energy-efficient heat pump.
