Abstract: Designers of building rehabilitation projects are often called upon to improve the structural, waterproofing, or thermal performance of wall systems in buildings undergoing rehabilitation work. The design of such improvements frequently requires envelope modifications that must be carefully analyzed to ensure that they are effective and to avoid unintended and negative consequences on building performance. The presentation will review modern envelope design requirements and provide recommendations for general design considerations and detailing, along with analysis techniques that can be used to assess the viability of rehabilitation options for existing masonry wall systems illustrated with examples from the presenter's experience.
