and so we saw a presentation by professor deerline.nything that really stands out that we should focus on immediately and then maybe in the long-term, and i'll just let anyone jump out. >> the building stock of tall buildings and the new building design, separate buckets for me. how do we look at the ones that professor deerline mentioned about the cohorts of buildings from the early 1970s to the 1980s to what we do today, and i can they should be looked at and recommendations are included for both, and it's hard to decipher, because we can improve the new buildings incrementally, a small percentage of what we see in the community, but the existing buildings are out there, and vulnerable buildings were mentioned that should have a look see and see if we can't improve their performance as well. >> and so today's, and having everyone here today is very important. existing buildings, a lot we don't know about, and so maybe angus with building inspection and planning, joel, think about what would we have to do to try and, from a city stand
