This will undoubtedly become more commonplace now that 'waste heat' is no longer thought of as a mere inconvenience. I've seen large in-city facilities that dump 'waste heat' through windows that open into the outdoor air in wintertime, right across the street from a row of multi-story apartment buildings.

For example, the article cited mentions that: "ADE estimates that 54 percent of energy used to produce electricity is being wasted via conventional power production, which relates to £9.5 billion ($US12.5 billion) per year." Siting housing next to power plants (and other plants with 'waste heat') is likely worth considering!

Yes. I had it in my previous home in germany.
