Proposed Session Description
The classic brick wall is un-insulated (R-6-ish) wythe thick wall, prone to air infiltration. Many buildings fall under some form of aesthetic scrutiny often exterior insulation is prohibited. Therefore, the only option to make these buildings energy efficient is to insulate them on the interior. WE take a close look at how to insulate these walls safely from the interior - considering moisture drive, bulk rainwater issues, and insulation materials - avoiding the dangers of freeze thaw and mold.
Why is this session important?
High performance retrofit's are the key to meeting our climate targets as well as NYC electriciation goals. Many Brownstones as well as apartment buildings can only be renovated by adding insulation on the interior for various reasons. The existing building stock in citys (NYC, Boston, Albany, Chicago) will have to renovated in coming decade - what low carbon, foam free, airtight and save methods can we employ?

 Maybe. The proposal is very practical and timely; however, I'd like to know more about the embodied carbon of the types of products they intend to discuss. Given the presenters, they may already be considering low embodied carbon products, but if they aren't this topic won't advance clean and resilient buildings because masonry retrofits have already been presented at past conferences

Maybe, leaning to yes - interior retrofits are not discussed enough and will be vital in the work of existing cities if we are to retain our city fabric. I also agree we need to confirm a low embodied carbon awareness before proceeding. I like the session layout as well, the 30 min then two case studies, then QnA.

Round 1 discussion:- Presenters are builder & architect- maybe because it is timely- Need more understanding if the content is advancing low-embodied product- Would they be open to combining/joining forces with #110?

Gwen McLaughlin Thu, 06/15/2023 - 7:07 am

Yes, combine with #110Presentation will focus on the increased desire to do low carbon renovations and will address how low carbon approaches can be effective in existing building stock, including improvements in systems and approaches that have made these types of renovations more effective and efficient overall Will include 2 case studies from 475 and the architect(s) listed in the proposal (co-presenters have confirmed their interest)Will incorporate lessons learned and feedback from GC Will develop additional content on embodied carbon, including good, better, best approaches to product selection and how to quantify the benefits of low embodied carbon materialsInterested in co-presenting with Mark and Cheryl

Diversity and Inclusiveness
low carbon and electrification is at the heart of the interior renovations. we strive to have equal gender representation with out co-presenters
Learning Objectives
Describe key attributes for high-performance enclosures and how historic masonry walls often fall short.
define how airsealing and vapor control effect the performance of historic masonry enclosures when insulting from inside
Describe ways in which high-performance goals can make a historic masonry wall stronger or riskier.
design solutions at floor, window and wall junctions that are both airtight, easy to construct and cost effective when insulating apartments inside of masonry buldings.
