I've not seen the presentation, but have some knowledge in heat transfer and home energy use, and would not expect anything near 40% energy savings from it. There would be some savings because it would reflect heat radiating from the roof. But, the attics in newer homes in The Villages are very well insulated. I'm sure that in these homes, the energy loss through the attic is much less than 40% of the total home energy use. Be careful of claims of savings "up to" any number.
