Mission Statement

Mission Statement

Our Vision:

A world where it’s widely acknowledged that our individual decisions about heating energy have as much impact on climate as electricity and transportation.

Our Mission:

To rapidly scale up our clean carbon future by empowering people to make climate-smart heating choices.

Our Strategy:

To foster a decentralized, open-source, consumer movement by clearly and simply explaining currently-available heating options, how they can be affordably integrated into our existing housing stock, and their relative carbon advantages so that consumers and heating professionals are empowered to make the smartest possible heating choices.

Our Mantra:

Turning heating education into climate action one home at a time.

Heat Loss

The two variables of of heat loss are a) geographic location, and b) building performance. Together they will determine the quantity of heat needed to maintain comfort.

Geographic location drives the building's “design day." Your design day is the difference in temperature between the inside and outside of your house on the theoretical coldest day of the year; so in the northeast we calculate a day that is -10ºf outside and comfortable 68ºf inside. This is referred to as the “delta-T” value. A typical delta-T for the northeast is 78º.

Building performance is the big one because there’s nothing we can do about geographic location. Today we can build a really tight thermal envelope, but most of our heating pollution comes from the millions of homes built over the last 100-150 years. We are getting better at buttoning-up those old buildings with insulation and weather sealing but weatherization is still  never going to be enough to overcome the heat loss from a 78º delta-T. That means we need heating systems that can quickly put a whole lot of heat back into those old houses on the days that are really cold.
