Measure Guideline: Deep Energy Enclosure Retrofit for Interior Insulation of Masonry Walls and Flat Roofs

Description

Measure Guideline: Deep Energy Enclosure Retrofit for Zero Energy Ready House Flat Roofs BSC TO5 Task 7.4 Deep Energy Enclosure Retrofit (DEER) for Interior Insulation of Masonry Walls Lawrence, MA 01840 This Measure Guideline describes a deep energy enclosure retrofit solution for insulating mass masonry buildings from the interior. It describes the retrofit assembly, technical details, and installation sequence for retrofitting masonry walls. Interior insulation of masonry retrofits might adversely affect the durability of the wall. This guideline includes a review of decision criteria pertinent to retrofitting masonry walls from the interior and the possible risk of freeze-thaw damage. This Measure Guideline is intended to support contractors who are implementing an interior insulation-based high-performance enclosure retrofit for masonry buildings and designers who are looking to design such retrofits. It may also be helpful to building owners who wish to learn more about strategies that are available for deep energy enclosure retrofit of masonry residential buildings on the interior. This Measure Guideline is important to the high-performance retrofit industry because the solution described here provides an opportunity to retrofit masonry buildings with ambitious energy performance goals by insulating them from the interior without disturbing their exterior appearance. BSC TO5 Task 7.4 Deep Energy Enclosure Retrofit (DEER) for Zero Energy Ready House (ZERH) Flat Roofs House Jamaica Plain, MA 02130 This Measure Guideline provides design and construction information for a deep energy enclosure retrofit solution of a flat roof assembly. It describes the strategies and procedures for an exterior retrofit of a flat wood-framed roof with brick masonry exterior walls using exterior and interior (framing cavity) insulation. The approach supported in this guide could also be adapted for use with flat wood-framed roofs with wood-framed exterior walls. Designers, contractors, and building code officials will benefit from the information contained in this Measure Guideline. The guide may also be helpful to building owners who wish to learn more about strategies for deep energy enclosure retrofit of flat roofs. This Measure Guideline is important to the high-performance retrofit industry because it demonstrates techniques for retrofitting flat roofs from the exterior, which is less disruptive to the living space and allows the structure to remain occupied during the project. It also illustrates a solution for preparing homes to become zero energy ready.
