Weird to look up one number, then fabricate $100k out of nowhere to compare it too. Plus, you are looking only at the energy bill, not the cost of energy saved.

The top comment in this thread states that 1.7% of the upfront cost of the apartment, $17,000, is for energy efficiency improvements. In fact, the codes that mandate energy efficiency improvements take a detailed cost analysis into account, and only mandate cost-saving energy efficiency improvements.
