key elements from top to bottom in sequence order.
There will be six one-hour sessions.
Each session qualifies for one AIA HSW Continuing Education Unit.
Certificates will be distributed at each session.

Technical Session 1
Water Retention/Detention Vegetated Roofing
Speaker: Oscar Warmerdam, SemperGreen 
Description:  Green roofs are a departure from typical horticulture where the garden is a largely aesthetic offering. A green roof also has plants like a garden, but is mostly a tool with different priorities and concerns. The performance of the plants over time are now vital in regards to wind uplift, soil protection, and erosion control, and at the same time, the system needs to have longevity and continue to function as a tool. First and foremost, it simply needs to manage stormwater.
Learning Objectives: This presentation will show the:
Three different kinds of actors in this process.
Objectives and why all three actors think they are correct.
Difference between the three thought processes that the new opportunities offers to the building owner.
Short Bio:
Oscar Warmerdam is a native from the Netherlands, a place where "water and too much of it" go hand in hand, as the climate in the Netherlands is one of continuous rain, or so it seems. Growing up on a plant nursery literally growing tulips, and then going on to horticultural schools in Holland ended with a trip to the USA, which obviously made him stay. For 18 years he worked for and later on ran a company that offered over 2000 different plants to growers across North America. This meant exposure to lots of different plants and the different ways to grow plants. Ten years ago the door opened to the world of green roofs.

Short Bio: Richard Hayden is the national Garden Roof Department Manager for American Hydrotech, Inc. based in Chicago, Illinois. Richard is responsible for the management of the staff that provides engineered LiteTop growing media, drainage materials, plants, edgings, and other supplies to contractors. Most recently, Richard has developed a ballasted Garden Roof using a permeable grid paver that can be planted to combine green space with ballast weight in Hydrotech’s protected membrane roof assemblies. Richard has been a practicing landscape architect and infrastructure, streetscape, urban designer for more than 37 years.

Technical Session 3

WUFI Analysis Explained
Speaker: Alejandra Nieto, MBSc, Rockwool North America (formerly Roxul)
Description: WUFI (Wärme Und Feuchte Instationär), meaning transient heat and humidity, is a software program used to help predict and understand the performance and durability of different assembly configurations under specific climatic and environmental conditions. It is recognised as an essential tool in designing high-performance building enclosures in the architectural and consulting industry, and is often used to influence design decisions in both new construction and retrofit projects. The inputs used in the modelling are critical to ensure appropriate representation of the assemblies.
Learning Objectives: This presentation will review the:
Use and applications of WUFI modeling.
Outline of the intricacies of the software parameters.
Identify and key considerations for interpretation and analysis of results.
Short Bio: Alejandra Nieto
is a Building Science Project Manager at ROCKWOOL North America. She is a graduate from the Master of Building Science program at Ryerson University; with a background in construction science and management, and architectural technology from George Brown College. She has experience in design and research of the methods and materials involved in energy efficient buildings and systems.  As a project manager and specialist in building science for ROCKWOOL Building Science, her role includes providing unbiased building enclosure solutions to the architectural community; advancing the research of enclosure system performance; and promoting energy efficient and good building science practices within industry. She is an active member in multiple ASHRAE technical committees; and is fluent in different modelling and simulation software including AutoCAD, WUFI, Heat 3, and THERM.

Technical Session 4
Air Barriers: Where You Are Matters
Steve Gordon, PPSI
Controlling heat flow, airflow, moisture flow, and solar and other radiation will affect the interactions among the physical elements of the building, its occupants, and the environment. Air barriers are systems of materials designed and constructed to control airflow between a conditioned space and an unconditioned space. The air barrier system is the primary air enclosure boundary that separates indoor (conditioned) air and outdoor (unconditioned) air. Air barrier systems also typically define the location of the pressure boundary of the building enclosure.
Learning Objectives: Upon completing the course attendees will be able to know the:
    Differences among an air barrier, a vapor barrier, and a rain barrier.
Differences between a vapor permeable air barrier and a non-permeable air barrier.
Importance of NFPA Requirements for Air Barrier Systems.
Short Bio:
Steve Gordon joined PPSI as a partner in in 1987, Steve brings 44 years of experience in technical product representation of building materials. He graduated with a BS in Business from Northeastern University. Steve has a broad base of knowledge of the architecture and construction industry, but specializes in the building envelope, waterproofing, green roofs, expansion joints, pavers and insulation.

Technical Session 5

Curtain Wall
Alan Geary, Curtain Wall Design Consulting

Description: This presentation will be an overview of design and performance attributes of glass and framing options frequently used in commercial construction. While focusing on 'curtain wall' and defining what that term means, it will be compared with similar "storefront" and 'window wall' designs.
Learning Objectives: This presentation will:
Explain the difference between curtain wall and storefront and window wall designs.
Identify the features of framing systems.
    Show how glazing and framing affect performance.
Short Bio:
Alan Geary was 15 when he first worked as an architect’s apprentice. Now, nearly 50 years later, his experience has both broadened and specialized while remaining rooted in building design and construction. With two degrees in architecture from RPI in Troy, NY, most of Alan’s career has allowed work with specialty high-performance windows, skylights, insulating glass and building enclosure materials. Since early 2015 he has been a consultant with Curtain Wall Design & Consulting, Inc., an international business helping design, specify, test, and critically observe commercial construction.

Technical Session 6

Topic: Commissioning of Building Enclosure
Keith Nelson, Intertek
Description: Building Enclosure Commissioning (BECx) is relatively new to the design and construction industries. This presentation will provide a primer on the practice of BECx and its benefits with real world case studies and then dive further into the various approaches as defined by industry standards and code.
Learning Objectives: Upon completing the course attendees will be able to:
Describe the general function and performance requirements of the building enclosure.
Describe the process of BECx with an understanding of the potential value the process may bring to a project.
Describe the various stages of BECx and the deliverables typically produced.
 Identify the various codes and standards bodies that have incorporated BECx into them.
Identify and discuss the differences between the application of BECx in the various standards & model codes.
Short Bio: Keith Nelson brings over eighteen years of critical evaluation of design details and field review of new and existing building enclosure projects. He has been involved in a broad range of projects throughout North America with services including enclosure evaluation, detailing, design and product submittal review, construction phase observation and evaluation, below-grade waterproofing investigation, testing and repair, and building code analysis. He currently serves as a voting member of the ASHRAE SSPC 90.1 Enclosure Sub-Committee where he leads the Air Leakage Working Group and an active member of ASTM E06.55 in the continued development of ASTM E2813 and E2947 regarding Enclosure Commissioning. Keith is currently the technical lead for the Building Enclosure Commissioning and Enclosure Consulting Practice Areas at Intertek Building Science Solutions.
