Tankless hot water
The Pratt House project is trying to demonstrate that a super-efficient home can be built without a lot of complex modeling and analysis and with everyday appliances.
Here is a relatively simple, electric hot water heater. But the way it's installed has been done with an eye toward reducing consumption. Each appliance that uses hot water has a dedicated feed, which reduces the amount of hot water that's piped around.
