Question:

Just a quick question. In buying/selling condos or apartments, do you take into consideration the energy efficiency of the building or the sustainability of the location? I am asking this with Climate Change as a reference.

You may consider that.

But I believe that worldwide, these factors weren't on top of the builder's priority. It is only now that these factors are considered and used more as a good angle of a marketing ploy.

The fact that there are other residents in the same building/ neighborhood makes it a viable residential place.
As investors, we prioritize things that are on top of the priority list of our buyers such as availability of water (surprisingly this is still a problem in some areas), electricity, accessibility, price etc.

Worrying too much leads to analysis paralysis
