You can use cathodic protection to extend the life of the rebar. But generally speaking there's no way around being on top of maintenance. Why design a building for 125 years of no one giving a poo poo about it? Also, if environmental consideration is paramount, consider that fifty years from now environmental technology may be considerably better. Imagine what an energy efficient building built in 1892 would look like and how much work would have needed to go into it between then and now. Saving money for eventual replacement or major upgrade fifty years down the line can be a better strategy than assuming you have to last unchanged from 2017 to 2142.
