Absolutely, we see that problem all the time and Len's point about having tenants and landlords at odds for who pays the energy bill and who should front the cost of capital to do these upgrades.
A common thing that we see...I think a really good example of a program that gets past all of this is PACE. It's a financing program that puts the burden on the property itself. It's tied to property taxes where the owner can invest long term into deep retrofits for a building and if that building is sold, that debt continues with that building.
It's a really nice mechanism for buildings that may not invest hundreds of thousands of dollars in capital to do energy efficiency because of that landlord/tenant, “What if I sell the building....” All these different barriers break through that completely, and there's financing available to do that.
