 Efficiency for all is a joint effort of the National Housing Trust, Elevate Energy, NRDC, other organizations to really promote the weatherization of multi-family units and by that mean mean apartment buildings. I work for a network of 42 agencies, non-profit agencies in Ohio that weatherize low income housing. We'll touch around 24, 25,000 homes this year, probably providing comprehensive weatherization services to 14,000. The rest will be probably base load or basic electric efficiency services and we'll do a lot of those in multi-family buildings. The health benefits of weatherization have been apparent for a while. They're primarily driven by indoor air quality improvements. The literature demonstrates that we have a pretty tremendous impact in reducing asthma triggers and reducing triggers for COPD attacks. Also helps people with hypertension and heart disease to live in a better quality house. Now it's not just the indoor air quality, it's also consistent temperatures, fewer drafts, all of that contribute to health improvements for our clients. So a recent Department of Energy study found that the value of the health improvements was about $14,000 per home in the form of lower medical costs, fewer missed days of work or school, and then obviously quality of life. You've seen a steady increase in appropriations over the past couple of years, so that's certainly helpful. And I think continuing to encourage utilities to partner with and invest in the network and invest in their customers to help them stay in their homes in an affordable way, that's where we really see the future is continuing partnerships with all of the funding sources so that we can maximize the impact we have on our neighborhoods and our states.
