Day Two: Tuesday, January 8
Session TU2A: Resilience: Learning from the Past, Adapting to the Future
10:15 am – 11:00 am
Lessons Learned from the 2017 Hurricanes & Mitigation Assessment Reports: A Technical Evaluation of Building Performance & the Impact of Code Adoption and Enforcement
Dan Bass, FEMA Mitigation Assessment Team Program Manager, FEMA
Stuart Adams, Associate, Environmental Services, Stantec
Manny Perotin, FEMA Technical Assistance Contractor, CDM Smith
Deploying Mitigation Assessment Teams (MATs) is one of the activities that the Federal Emergency Management Agency (FEMA) carries out in response to natural disasters caused by events such as floods and hurricanes. Following disaster events in 2017, FEMA sent teams to Texas, Florida, Puerto Rico and the U.S. Virgin Islands. These teams are formed by and operate under the direction of the Risk Management Directorate's Building Science Branch, located at FEMA Headquarters. The MAT conducts field assessments and technical evaluations of the performance of buildings subjected to forces generated by the event. The primary purpose of the MAT's technical assessments is to identify design practices, construction methods and building materials that either failed under the forces generated by the event or were successful in resisting such forces. In addition, the MAT often will look at land use management and planning practices, as well natural hazard identification and risk assessment. This is done to learn whether actions, other than those involved in designing and constructing buildings, were successful in minimizing damages from natural hazards. One of the major objectives of the MATs is to provide recommendations that can help reduce future damage from natural disasters. The MAT's findings and recommendations are aimed primarily at construction contractors, architects, engineers, planners and those local building officials who are involved in permitting, inspection and development of building codes, as well as floodplain and land use management provisions.
11:00 am – 11:45 am
Climate Resilience: A New Paradigm for Buildings?
Mohammed Ettouney, DSc, Mohammed Ettouney LLC
A widely accepted definition of infrastructure resilience is the capability of those infrastructures to withstand to, and then recover quickly from, abnormal demands. Many of those abnormal demands are climate-related. Many of potential climate change demands, as might result from observed global warming have raised concerns of civil infrastructure stakeholders. Intensity and frequency of recent climate-related events, such as north Atlantic hurricanes Harvey, Irma, Maria, etc., were attributed by many to global warming / climate change. Civil infrastructure resilience, as defined above, during and in the aftermath of those demands varied greatly. With the expected continued increased impact of climate change on civil infrastructure, a more robust resilience performance is needed from those infrastructure systems. This presentation explores the interrelationships between climate change effects and infrastructure resilience. Such interrelationship is complex due to the complexities of both climate change and resilience. To simplify the task, the speaker will first illustrate the nature and components of both, then survey how the components of both climate change and infrastructure resilience interact and, finally, illustrate the needed objective processes for enhancing infrastructure resilience due to potential climate change demands.
Session TU2B: Intelligent Tools and Technologies: Micro to Macro
10:15 am – 11:15 am
Smart Cities Can't Exist without Machine Learning
Fiip Ponulak, PhD, Director of Data Science, Site 1001
Machine learning has taken residence at our cities' cores and now we can finally have “smart cities.” Cities are a collection of buildings made to provide the structure and safety necessary for people to function, create and survive. Buildings are a pool of ever-changing performance data from large automated systems, such as heating and cooling, to the people that live and work within them. Through machine learning, buildings can optimize performance, reduce costs and improve occupant comfort by sharing information within the building and with outside city infrastructure via real-time shared cloud capabilities.
Add Lasers to Your Workflow! An Intro to Point Clouds
Kyle Barker, AIA, Associate/Project Architect, MERGE Architects
3D laser scanning promises architects greater efficiencies and cost savings in designing, building and restoring spaces. Yet, investing time and resources in mastering the technology has created fear, uncertainty and doubt about the potential yield. This session will explain the basics of scanning and explore the latent possibilities of the technology. The speaker will describe the differences between photogrammetry and light detection and ranging (LiDAR), the most common scanning technologies); demonstrate the use of a commercial laser scanner; highlight the benefits of the technology in construction document delivery; and explore cutting-edge uses for laser scanning, while imagining its future potential.
11:15 am – 11:45 am
Steps for Successful Building Systems Integration
Matthew Ezold, Principal, Cerami & Associates
Our building systems are smarter than ever. However, the typical building design and integration process has not kept up with the times. Integrating modern building systems, from environmental systems to user-aware sensing systems, into a cohesive platform that enhances the user experience requires proper planning and careful delineation of scope between various systems designers and providers. Using a theoretical multi-tenant building, this session will outline the steps and schedule for identifying potential building systems integrations, determining the tenant/landlord benefits for integration, designing and coordinating systems scope and then bringing the systems contractors to the table to ensure interoperability across all systems. This session will also define some new project team roles, including that of the building systems architect and highlight building network design options for both single- and multi-tenant buildings.
Session TU2C: Building Enclosure from Top to Bottom
10:15 am – 10:45 am
Hygrothermal Performance Assessment by Simulation - Motivation & Remaining Challenges
Manfred Kehrer, Senior Associate, Wiss, Janney, Elstner Associates, Inc.
Elizabeth Pugh, Associate III, Wiss, Janney, Elstner Associates, Inc.
Numerical simulation of the combined heat and water transfer in building enclosures has been an established practice for over 20 years. Besides other performance assessments, like laboratory and field test measurements, numerical simulation is considered an essential tool in the toolbox for building enclosure design and forensic analysis. Most of the physical phenomena of heat and moisture transfer, such as heat conductivity, radiation, vapor and capillary transport, are well understood. The majority of these physical phenomena can be fairly accurately simulated with hygrothermal analysis tools for practical application, although another phenomenon, convection, is still hard take into account for building practice. The speakers will discuss research that is being completed that uses measured data from the instrumentation of a new facility, as well as numerical simulation to acquire more knowledge about convection behind commercial building cladding systems and to validate a finite element tool that simulates the combined conductive, radiative and convective heat transfer on interior surfaces such as windows and wall/roof surfaces. The presentation will show the basics and the importance of hygrothermal performance assessments, especially in today's world of high performance buildings and buildings enclosures. Furthermore, up-to-date results of the recent research project will be demonstrated.
10:45 am – 11:15 am
Specifying Cladding Attachment Systems: The Holistic Approach
Neil Norris, MASc, P.Eng, CPHD, Building Science Engineer, Morrison Hershfield Ltd.
With increasing requirements for the building enclosure in energy codes, many building projects are moving towards using exterior insulated building assemblies. Exterior insulated systems allow for increased thermal performance but much of that depends on the design of the exterior cladding attachment system. There are a wide variety of secondary structural attachment systems in the North American market competing to provide better thermal performance, which can be overwhelming for designers to compare for use on their projects. While direct comparisons of components ("clip to clip") may show two systems to be equivalent, it is not until additional project requirements are brought into the comparison that significant differences in performance can arise. These additional requirements include structural considerations, like wind and dead loads, which dictate the spacing of components, combustibility restrictions on components and installation flexibility. The perceived advantages in performance from one system over another may not actually turn into tangible benefits in reality once these other design requirements on the project are also satisfied. The intent of the presentation will be to provide the necessary background information, calculations, methodologies and available resources to guide designers in making informed decisions for selecting the right cladding attachment systems for their projects.
11:15 am – 11:45 am
Adding Air Barrier and Thermal Improvements to Existing Facilities
Brian H. Neely, AIA, CDT, BECxPSM, Senior Project Manager, Gale Associates, Inc.
In order to meet energy savings and reduce carbon footprints, facility owners are looking at options to increase the thermal performance and interior air quality of their facilities, especially those buildings constructed prior to the induction of an energy code. This presentation will provide an in-depth examination of design considerations, with a focus on addressing ongoing air and moisture infiltration caused by the lack of continuous air barriers and thermal insulation. The presentation will discuss unique solutions to improve overall building performance and aesthetics, and coordinate construction in an occupied facility.
Session TU3A: A Building's Umbrella: Keeping Water at Bay
1:45 pm – 2:30 pm
Air Leakage and Water Penetration Testing of Flanged Window Details
Keith A. Simon, AIA, CPHC, LEED AP, Senior Architect, BES/Terracon
John Posenecker, PE, Department Manager II, BES/Terracon
Trevor Brown, Senior Quality Control Manager, JE Dunn Construction
In multifamily construction, a variety of water-resistive barriers (WRBs) are utilized and a variety of details within each WRB manufacturer are utilized. There exists very little data in the industry for which detailing and installation methods are better for air and water penetration. For example, building wraps, sheathing systems with integral coatings, and thin-mil fluid-applied WRBs can all be applied according to ASTM E2112 Standard Practice for Installation of Exterior Windows, Doors and Skylights – Method A and A1 (no sealant nor flashing tape at the sill flange) or Method B and B1 (sealant and flashing tape at sill flange) in combination with low-pressure foam at the interior perimeter or backer rod and sealant at the interior perimeter, and various options for flange sealant (silicone, polyurethane, butyl, etc.). A consulting company and a general contractor partnered to build a series of 4' x 8' mockups – each with the same simulated flanged window, but each one detailed according to a distinct, but common multifamily window detail and WRB, and tested each mockup according to ASTM E1105 Field Determination of Water Penetration of Installed Exterior Windows, Doors, and Curtain Walls by Uniform or Cyclic Static Air Pressure Difference and ASTM E783 Field Measurement of Air Leakage through Installed Exterior Windows and Doors.
2:30 pm – 3:15 pm
The Rainscreen Blame Game and a Real-World Solution
Cory Robbins, Business Development, EDA Contractors Inc.
The Rainscreen principle is quickly becoming the preferred method of enclosing buildings in America, making its way across the Atlantic from Europe where it has become the status quo for decades. This presentation dives into the concepts behind the rainscreen principle and the method of procurement, which puts the project in peril before it ever commences… creating a ripe environment for a terrible game after substantial completion: The Dreaded BLAME GAME!
Session TU3B: Rural Studio's 20K Initiative and the Total Cost of Affordable Housing
1:45 pm – 3:15 pm
Rural Studio's 20K Initiative and the Total Cost of Affordable Housing
Panel, including Rusty Smith, Associate Director, Rural Studio, Auburn University
For 25 years, Auburn University Rural Studio has directly engaged in research and real-world applications related to the development of rural prosperity in West Alabama, an area where approximately 30% of the population lives below the poverty line. Harnessing this knowledge, the 20K Initiative, a Rural Studio project, aims to develop a scalable, sustainable, agile and resilient delivery process for well-designed, affordable homes titled as real property in underserved rural communities, including the 301 non-metro U.S. counties considered “persistently impoverished.” In order to address the systemic issues underlying the housing affordability crisis in rural America, the project analyzes what the house costs to purchase, as well as what it affords the homeowner once it is occupied. By coupling ‘first cost’ inputs with the outcomes of ‘second costs’ of homeownership, the initiative works to create a new paradigm for housing affordability. Focusing on the home's energy performance and durability, the project aims to address the systemic issues underlying the housing affordability crisis through replacement of an existing stock of substandard residences with safe, secure, healthy and high-performing dwellings. This paradigm shift aims to better protect the investment of lender, insurer and homeowner, while also increasing rural prosperity.
Session TU3C: Managing Facilities and Assets
1:45 pm – 2:30 pm
Managing Assets Starts with a Comprehensive Master Plan
James Easter, Principal, Easter Healthcare Consulting (Ehc)
With over 5,000 hospitals, 400+ systems and numerous ambulatory care centers around the USA, how will the campus master plan (MP) change? The change will require a "global perspective from 50,000 feet" to understand how service systems can operate more effectively with less waste and advanced technology. In addition, each building and hospital campus will require a regularly scheduled MP product to manage the assets, determine most appropriate budgetary allocations and methods for assessing the ROI and VALUE of the investment. This MP should include quantifiable metrics, project justification analysis and data-based narratives to quantify what, where, when and why? In the future, the ideal MP will be combined with a functional program, process improvement narrative and facility management (FM) protocol. Without these linkages working in harmony, the resulting plan will fall short of competent business efforts. A finely orchestrated strategy, in synch with the MP and the FM management efforts, will reduce waste, significantly improve patient care and respond specifically to use needs. Users represent all departmental and service leaders on each site and within the delivery system. No, not everyone will gain approval of their projects, but the road map will be clearly delineated and measurable for all to understand. Training for staff and regular updates of the SP + MP + FM and technology enhancers work effectively when understood and communicated clearly to the C-Suite and other responsible partners.
2:30 pm – 3:15 pm
Facility Management: Transition Planning, Activation and Funding
Casey Martin, CFM, AIA, AICP, Program Manager, Jacobs Engineering Group, Inc.
Eric Dillinger, Vice President for Strategic Consulting Services, Woolpert
If not planned well in advance, the transition of a new facility from construction to operation can be chaotic and costly to the owning organization. For the long-term operational success and viability, operational efficiencies require attention and development during the design and construction phase. A predictable opening day is dependent on having critical success factors in place, such as an operational readiness transition plan, an asset management strategy and an understanding of maintenance costs. This presentation will address how aligning expectations between the facility management (FM) organization and customers can make life easier for both sides. Funding levels can fluctuate with customer expectations for response times, quality, service frequencies, level of effort and services included in the agreement. The speakers will discuss how developing a structured service menu with levels of associated funding requirements can set the stage for exceeding expectations without exceeding the FM budgets and controlling for quality. Measurements and metrics can be established that are fair and understood by bot the delivery organization and the customer. The speakers also will review the new ISO Facility Management Standard 41012 for best practices on developing service level agreements.
Session TU4A: Science Fiction or Construction Reality?
3:30 pm – 4:00 pm
Augmented Reality in Construction
Matthew Vanture, VDC Manager, The Whiting-Turner Contracting Co.
Vast amounts of time are committed to planning a construction project, no matter the size. Once planning is complete, ensuring installation occurs per the plan takes many forms. In the field, installers use different processes, from drawings and a tape measure all the way to multiple scans of the building at intervals through the job. These efforts can be wildly time consuming and may even miss some items. Advancements in technology allow new options, such as augmented/mixed reality (AR) solutions, . With AR hardware and building information modeling (BIM) tools used for planning a job, contractors can quality control (QC) a space just by observing it through devices. Such tools allow teams to save time on schedules and money on reduced rework, and ensure the plan created is the one executed.
4:00 pm – 4:30 pm
Leveraging Artificial Intelligence for Structural Design
Robert Otani, PE, LEED AP, Chief Technology Officer, Thornton Tomasetti, Inc.
The use of Artificial Intelligence has the potential to radically disrupt consulting engineering methods that have been largely unchanged in the last 50 years. The advent of computers and building information modeling (BIM) have changed how the industry delivers the documentation/drawings, but the actual process of engineering and advances in productivity have been static. Further, artificial intelligence algorithms can capture engineers' domain knowledge in a way that can allow a very large firm to capture the knowledge of an entire firm and have that knowledge and expertise readily available to all of the engineers in the firm. That level of knowledge sharing is not possible in the conventional methods of learning via person to person. The speaker will discuss a new software that can provide a structural design of a building, including the gravity system, lateral system and foundations, from a massing in just seconds, which would normally take engineers weeks to complete.
4:30 pm – 5:00 pm
The Robots Are Coming: How Robotics Will Affect Design and Construction
Jeff Gravatte, CEO, CAD Microsystems
Robotics will have a dramatic effect on how we design and construct buildings. In this session, attendees will learn how robots such as drones, total stations, assembly machines and prefab lines will evolve the way buildings are created. Building information modeling plays a key role in how this change will be actuated. The speaker will discuss how these and other technologies converge to create a new design and construction paradigm.
Session TU4B: The Past and Future of the Building Enclosure
3:30 pm – 4:15 pm
What's Next? Evolution of the Building Enclosure and Future Trends
Patrick Reicher, Associate Principal, Raths, Raths & Johnson
Elise Love, Senior Associate, Wiss, Janney, Elstner Associates, Inc.
Required functions of building enclosures, breadth of innovative materials and systems, technological advances, building and energy code requirements, and methods of construction have changed dramatically over the past quarter century. With this advancement, and the improved industry understanding of building science principles, building enclosures have evolved and become increasingly complex. This presentation will explore the evolution of building enclosures and future trends through a review of codes and standards, material and product development, changing owner expectations, accelerated project schedules, integrated project delivery methods and other factors. The speakers will present feedback from interviews with architects, general contractors, specialty subcontractors, product manufacturers, building owners, code officials, industry association leaders and other project stakeholders. In conjunction with the research and interviews, project examples and case studies will illustrate specific challenges encountered with modern complex building enclosure design and construction. Accumulated research also recognizes the impact of building enclosure evolution on once separate industries, such as the roofing and exterior wall industries, and their ongoing unification.
4:15 pm – 5:00 pm
Back to the Future: Re-Cladding to the Past
Lee Fink, Senior Project Architect, Thornton Tomasetti
Nicole Peterson, Project Director, Thomas Tomasetti
As energy conservation initiatives continue developing within urban environments, many cities have required transparency of building performance through energy benchmarking reports. Examination of these reports indicates that many older buildings outperform buildings constructed in the present day. A major contributing factor for this is envelope performance: older buildings are successful in limiting their window-to-wall ratio (WWR) and incorporating large amounts of opaque areas with high-insulating values, which is contrary to the highly-glazed projects seen today. With many post-modern building façades nearing their service life, repositioning projects are becoming more popular options to revive building envelopes. Typical post-modern façades contain fully-glazed exteriors and are often re-clad with a slightly higher performing curtain wall system. Instead of re-cladding glazed areas in-kind, can we look to the past and redesign these facades to incorporate higher-performing opaque assemblies with newer technologies? Can the performance benefits of high-insulating opaque areas outweigh the aesthetic advantages of fully-glazed enclosures? These questions and more will be explored during this comprehensive technical presentation. A re-clad case study for a post-modern high-rise building in Chicago, Illinois will be evaluated. A design tool showcasing the assessment of various impact areas (e.g., energy, daylighting, occupant comfort and cost) will be presented using qualitative and quantitative analysis.
Session TU4C: The Steps behind Building Resilience
3:30 pm – 4:15 pm
Innovate Solutions for Post-Disaster Code Enforcement – Development of Sustainable Permitting, Inspections and Building Code Programs
John Ingargiola, El, CABO, CFM, Lead Physical Scientist & PTS Building Science PM, FEMA
José Valenzuela, State Hazard Mitigation Officer, Central Office of Recovery, Reconstruction & Resilience (COR3)
Michael Rimoldi, Federal Alliance for Safe Homes, Inc. (FLASH)
In September 2017, Hurricanes Irma and Maria impacted the U.S. Virgin Islands (USVI) and Puerto Rico, devastating residential buildings; specifically, one- and two-family homes. The Federal Emergency Management Agency (FEMA) leads the response to these disasters and continues to provide on-going support, response and reconstruction activities. FEMA's Building Sciences Branch (BSB) provided specific technical guidance related to reconstruction activities, as well as support to the territories as they considered adopting the latest hazard-resistant building codes and standards after the storms. In the USVI, FEMA BSB supported the Department of Natural Resources with an update and expansion of technical guidance provided by the Construction Information for a Stronger Home. It provides multi-hazard design details and prescriptive solutions of single-family homes using primarily wood-framed solutions across the three islands of the USVI. These designs comply not only with the current USVI Building Code, but with the hazard-resistant provisions of ASCE 7-16 Minimum Design Loads and Associated Criteria for Buildings and Other Structures (2016 Edition, ASCE 7-16). In Puerto Rico, FEMA BSB supported the Permits Management Office with the development of prescriptive design details and solutions for single family homes based on the hazard-resistant provisions of ASCE 7-16. The use of the design details and solutions are permitted by the current Puerto Rico Building Code and these solutions provide an opportunity to assist designers and contractors with understanding the necessary engineering and details required to address vulnerabilities.
4:15 pm – 5:00 pm
A 2020 NEHRP Effort: What Changes to Expect in the Seismic Provisions and U.S. Seismic Value Maps
Jiqiu Yuan, PE, PhD, PMP, Project Manager, National Institute of Building Sciences
S.K. Ghosh, President, PhD, S.K. Ghosh Associates LLC
Nicolas Luco, PhD, Research Structural Engineer, U.S. Geological Survey
Mai “Mike” Tong, Senior Physical Scientist, Federal Emergency Management Agency
The National Institute of Building Sciences Building Seismic Safety Council (BSSC) develops the National Earthquake Hazards Reduction Program (NEHRP) Recommended Seismic Provisions for New Buildings and Other Structures with support from the Federal Emergency Management Agency (FEMA). The NEHRP Provisions provide state-of-knowledge information to improve the current seismic design procedures in the national standards and model building codes. The major changes in the 2015 NEHRP Provisions were accepted and incorporated into American Society of Civil Engineers/Structural Engineering Institute Minimum (ASCE/SEI) 7-16 Minimum Design Loads and Associated Criteria for Buildings and Other Structures, which were then adopted by the 2018 International Building Code (IBC). The BSSC is now in the process of developing the 2020 NEHRP Provisions, which are intended to be used by ASCE/SEI 7-22 and the 2024 IBC. This presentation will provide an overview of the FEMA NEHRP Program, an introduction to the Provisions development process, and an update on the latest topics being investigated by the BSSC Provisions Update Committee (PUC) and BSSC Project 17 Committee (P17) for the 2020 cycle. The PUC develops technical proposals related to ground motions, seismic design and analysis procedures, and structural system selection, aiming to advance various sections of the US seismic standards. Project 17 is a joint effort by FEMA, BSSC and the United States Geological Survey (USGS) to develop next-generation seismic design value maps. Project 17 is investigating many fundamental issues related to seismic design maps, such as acceptable risk, stabilizing mapped values and refining the values as a function of building height and soil type.
