BEST5 Conference: Drainage Capabilities and Heat Loss of Different Inverted Roof Assemblies

Derek Budde, Building Science Consultant, is presenting Drainage Capabilities and Heat Loss of Different Inverted Roof Assemblies at this year’s BEST5 Conference in Philadelphia, PA. This presentation is based on the research conducted and published by Derek and Morrison Hershfield’s Matthew Pel. The session will take place at 2:30 p.m. on Wednesday, April 18.

Presentation Overview:
Energy use in buildings throughout North America has attracted significant attention over the past decade. In cold marine climates, rainwater management is also a critical aspect of the building enclosure and energy performance. Various drainage practices used for low slope inverted roofing are often designed without quantified data available regarding the cold rain affects on the thermal performance of the systems.
The effect of cold water under the roof insulation and its impact on the effective thermal performance in inverted roofs is well researched. The aim of this project was to develop a better understanding of the impact of cold rain events on the effective thermal performance of inverted roofs in an effort to develop
best practice inverted roofs design guidelines.
