Integrated building facades have the potential to play a significant role in the support of aggressive building performance goals but validation is critical to assure that the potential is actually realized. This presentation will address the role of integrated facades in significantly reducing energy use while supporting high levels of occupant satisfaction. For transparent facade assemblies, the primary factors affecting performance are the management of solar heat gain, optimizing daylighting while managing glare, visual connections, and thermal transmittance. The presentation will summarize a range of validation methods including material testing, test bed studies of assemblies, and verification of specific simulation methods. The focus of the presentation will be on a case study of the post-occupancy evaluation of a completed federal office building—EGWW. Validation of post-occupancy performance provides important feedback for further commissioning to fine tune building controls and other systems, and also provides a valuable feedback for improving future work by the design team and other professionals.
Cross laminated timber (CLT) is an engineered wood building system designed to complement light- and heavy-timber framing options. Now available to North American building designers, it offers the structural simplicity needed for cost-effective projects, as well as benefits such as fast installation, reduced waste, improved thermal performance and design versatility. This presentation will introduce CLT through a series of project examples while considering some of the more challenging aspects of CLT building design—such as fire and life safety, lateral and seismic design, acoustic performance and building envelope. Topics will also include the manufacturing and specification of CLT, building code considerations and available resources such as the US CLT Handbook.

This course will discuss the challenges of current lows-slope roofing applications and further explore the properties of insulation types and performance characteristics under different operating temperatures. Participants will learn of an alternative insulation selection strategy using a hybrid approach combining both polyisocyanurate and mineral wool. Dimensional stability and constructability of the hybrid system will be explored in addition to the implications of roofing color and energy transfer through the insulation assembly.

A panel discussion that reviews the challenges and opportunities of the Enclosure Development Process. This discussion will include the perspective of the Architect, Contractor, and Owner regarding the successful and “challenged” processes for going through iterations of modifying the Enclosure. Specifically the panel will discuss examples of successful value engineering processes; a review of why we do not always get what we want, and also cases where the envelope wins; what to avoid early in the process (starting with systems that the budget will not support); what to avoid late in the process (losing sight of why early decisions were made); key decisions to make and commit to; how to analyze trade-offs to support the Owner's goals; what have we learned; and what do we still need to learn.

Surprisingly little research has been done into the effectiveness of different drip edge designs. Drip edges are found at window sills, window head flashing, and the edges of roofs and balconies – all critical areas for managing rainwater. By deflecting rain from the exterior surface of a wall, drip edges can reduce moisture-related issues such as freeze thaw of masonry, staining of the cladding, and potential long term erosion of historical materials. In this session, Jonathan Smegal will describe recent research into effective drip edge design. The study he will discuss used a custom-designed apparatus to compare the effectiveness of different drip edge materials, profiles and overhang distances. The results show a significant range in performance. Based on these results, practical guidelines will be suggested for choosing the best drip edge for your project.

This tour will feature in-progress construction of the largest Passive Haus project in North America to date. Attendees will hear from both the design and construction teams about the challengers and solutions to creating a project that will meet the Passive Haus standard. The design and construction team will share their experiences as members of a collaborative team that has worked together to come up with solutions to meet the high level of air tightness and thermal barrier continuity required by the Passive Haus standard. Of particular interest will be the changes to the design process required by the construcion schedule and methods of construction. A thorough review of the building enclosure construction will highlight air control and thermal control continuity, both as designed and as constructed.
