There are two routes that can lead an owner to deep energy efficiency improvements. If they are already in the mindset - a deep modeling will help settle any fears and doubts - plus guide them on the paths to take. The other path is eventually to implement nation wide energy benchmarking on commercial buildings, apartments and perhaps some homes. The benchmarks are available for all to see - which means there will be market pressure for the owners to improve (that triggers a request for a deep energy model).
Energy benchmarking is a much simpler task for the majority to use - and it will trigger owners or possible tenants to ask about possible improvements.
