Work on the HFOT home continues. Included: the requirements for ADA-approved and Energy Star-rated homes; the technology behind touchless faucets and toilets; and the technology behind the automatic-door opener that's being used on many of the doors. Also: using a beveled piece of marble to create an ADA-compliant threshold in the shower. In the second half: installing an electric vehicle charger next to a house; and installing a new kitchen sink.
