To clarify, such 'on-demand' water heaters are available worldwide on 
both electricity or gas. My parents have been running one in the USA on 
gas for 20 years. In Israel they have both electric and gas models (not 
that particular company however).

Anyhow, these on-demand systems are FAR more energy efficient than a 
tank. This should be self-evident--a tank is sitting with hot water when 
you may or may not need it, but the on-demand systems are dormant until 
you need them, and they only heat what you need.

Regarding "building green", a friend of mine shared this with me:

AS far as phone-rigged door intercoms, those are available today.
