The building enclosure is arguably the most important factor in a durable building. It encompasses the most critical function of a building: to separate the inside of the building from the outside. Therefore, it requires careful consideration from architects. This course provides needed context to explain how sophisticated building enclosures have evolved over time and delves deep into the best material selection for the functioning of the building. Considerations include rain and vapor strategies, acoustical performance, and fire and safety design.

Ryan Lobello, AIA, CPHD, NCARB, Senior Associate, Handel Architects, New York City, presenting The House at Cornell Tech, graduate student housing.The House at Cornell Tech is one of the most energy efficient buildings in the world. The House is part of Cornell Tech's new 2.1 million-square -oot technology campus on Roosevelt Island in New York City. The building is designed to reinforce the unique model of academic integration, multi-disciplinary research, and collaboration at the core of the Cornell Tech mission. It serves as a lively and comfortable living place for informal social interactions between students and faculty while they reside on campus. The House, the residential component of the campus, was designed to Passive House standards, which drastically reduces energy consumption while creating a healthier and more comfortable living environment for a fraction of residents’ usual energy costs. The House is the largest and tallest residential building in the world built to Passive House standards.

Architect Sara Bayer AIA, CPHC, NCARB, LEED AP, Associate Principal and Director of Sustainability at Magnusson Architecture and Planning in New York City, will present two affordable housing projects built to Passive House standards. The 94-unit Rheingold Senior Residences in Brooklyn, and the 85-unit Dekalb Commons in the Bedford Stuyvesant neighborhood of Brooklyn.

Todd Kimmell, CPH a Certified Passive House Designer and Regional Architectural Manager for Rockwool, will present three projects representing three distinct strategies to provide durable deep energy retrofits of buildings using fire-safe stone wool insulation. Those include using stone wool EIFS on Ken Soble Tower in Hamilton, Ontario (which is Passive House Certified); a rainscreen overcladding with stone wool on the 201 East 79th Street building in New York City, and a historic masonry retrofit with stone wool on the 1701 Abermarle Road building in Brooklyn.

The presentations will be followed by a moderated discussion focused on how these innovative projects address several key issues.
