Developed about three decades ago in Austria, panelized mass timber products have been used in Europe for some time but are now gaining market traction across North America and represent an opportunity for designers, developers, engineers and contractors. With this new design opportunity in North America comes jurisdictional code performance requirements that need to be demonstrated to building authorities in the United States. Among these are requirements for fire, seismic and acoustic testing. Acoustics standards in the United States are prescribed by various organizations, such as the International Code Council (ICC), Housing and Urban Development (HUD), American Nation Standards Institute (ANSI), American Society for Testing and Materials (ASTM) and Facility Guidelines Institute (FGI) and are codified by jurisdiction based on building typology. In addition to code requirements, the economics of occupant satisfaction and well-being play a role in project development. Economic studies have shown that consumers value spaces with higher acoustic quality and display a willingness to pay for the relief from unwanted noise.1 Furthermore, noise intrusion in places where people spend a majority of their time has been shown in a body of literature to effect cognitive function, disrupt sleep patterns, promote irritability, and provoke heart conditions.2 Therefore, in order for a housing project to perform, it must not only meet code requirements but also market expectations for high quality, acoustically separated living spaces. The acoustic performance of mass timber panels is measured by two metrics: STC (sound transmission class) and IIC (impact insulation class). STC, for example, is how well a wall assembly acoustically separates two spatial volumes. IIC is a measurement of how well a floor dampens the sound transmission of an impact between two adjacent spatial volumes, be that a dropped object or footstep. For multifamily housing, the International Code Council (ICC) prescribes a wall and floor assembly performance standard to meet or exceed a STC rating of 50 in a lab test (ASTM E 90 )or 45 in field tests (ASTM E 336) and IIC rating of 50 in a lab test (ASTM E 492) or 45 in field tests (ASTM E 1007).3 Using industry standards such as ICC, HUD, ANSI, FGI as a starting point for designing a series of floor and wall assemblies we hope to find high performing cost-effective acoustic solutions for mass timber assemblies that can be readily adopted by design teams and jurisdictional authorities . In addition, this study aims to provide more third-party verified data on CLT + MPP acoustic performance and disseminate it into the public sphere. 1.

INTRODUCTION1.0 Section 2.0 | 5© 2019 Energy Studies in Buildings Laboratory, University of Oregon Energy Studies in Buildings Laboratory The following section illustrates the resulting CLT and MPP wall and floor assemblies that are proposed for acoustic testing based on market feedback. The wall and floor assemblies are optimized with careful consideration to the economics, aesthetics (desire for occupants to see mass timber in assembly construction), wellness (IAQ of material emissions), and acoustic viability that can be afforded by mass timber construction. One grouping of floor assemblies is a structural composite and features a 2-1/4” concrete slab mechanically bonded to a 5-lam (6-7/8”) CLT or 6” MPP base. The base assembly (F01) was developed by Oregon State University and SOM for use in regions of high seismic activity.1 Due to the requirement for concrete to be bonded to wood, the dense concrete topping is not acoustically decoupled from the wood panel as is customarily the case. Therefore, lab testing data is needed to understand this structural composite’s acoustic behavior. The second grouping of floor assemblies uses a construction sequence that does not require wet trades. To do this, three layers of cement board are bonded together for a 1-1/2” topping in place of a poured concrete topping. This floor assembly was developed from feedback that design teams wanted to increase construction speed by eliminating the need for concrete to be poured, formed, and cured. The use of a dry mineral aggregate, such as sand or gravel, was investigated as an option since this is used in Europe; however, an additional consideration from contractors is that they preferred a material that crews were already familiar using, such as cement board. Currently, many mass timber buildings constructed or under construction are employing framed exterior walls. However, the potential for cost savings from using mass timber panels in shaft walls or as pre- manufactured off-site assemblies exists; therefore, influenced the final selections for testing. The wall assemblies utilize a prototypical exterior rainscreen assembly while maintaining the aesthetics of a natural CLT finish. Furthermore, the outboard insulation levels are sized to meet energy code requirements of most U.S. climate zones. 1. Skidmore, Owings, and Merrill. Timber Tower Research Project.

There was tremendous enthusiasm from industry to have more tested and verified assemblies at their disposal so that design teams can be flexible when bidding projects, such as having alternate assemblies with comparable performance available that can be substituted based on market conditions. The general summary of feedback that we received included a desire for generic materials, less wood fiber in the base construction, speed of assembly and visibility of the mass timber substrate. During testing, both laboratory facilities were very helpful, educational, and accommodating to our research team. Being on-site during tests was an advantage to quickly understand and resolve issues that develop. A few of the lessons learned during testing include: 1. Original construction drawings needed updating for as-built due to some clarification. For instance, 145 pcf concrete was specified; however, available concrete used for testing was 151 pcf. 2. Some of the CLT had holes in an exterior layer where knots may have fallen out leaving 1-1/2” deep holes in the face. 3. MPP half lap slightly off in depth to cause a ~1/8” change in elevation rather than being flush, one side of the lap 3” and the other side of the lap 3-1/8”. 4. The MPP 1” plywood units sometimes have an air gap at the butt joint and those gaps can line up on every other layer, effectively reducing the sound path to half of the sectional dimension. 5. In future, it might be nice to specify sealing the half-lap joint at the perimeter face edge to prevent edge short circuit but it probably would not change these results very much but would represent larger panels better removing this edge effect. 6. MPP wall panels were a tight fit because the panels were slightly wider (50-1/4” rather than 50”).

The goal of this survey was to document known assembly performance data and identify desirable CLT and MPP assemblies based on construction technique, performance, aesthetics and cost. Some of the assemblies are developed by us to gauge new directions that industry might consider and flag immediate needs due to a paucity of published data in order to reduce market barriers by providing the needed testing. The results from these tests will be disseminated to the building industry to facilitate mass timber construction projects by reducing market barriers. These identified assemblies were compiled into a document which was sent out to twenty-three different developers, engineers, acousticians, architects, and contractors as a market climate field survey. Of the twenty-three surveys sent out, twenty were returned. By crowd-sourcing our efforts we were able to optimize two wall assemblies and two floor assemblies to provide value to the building industry.

N Section 6.3 | 48© 2019 Energy Studies in Buildings Laboratory, University of Oregon Energy Studies in Buildings Laboratory INDUSTRY FEEDBACK6.3 The following section is a compilation of emails, phone calls, and survey responses and meeting feedback from industry professionals who have designed, specified, engineered or constructed with mass timber. We reached out 23 individuals and their response data informed our assembly decisions and guided the final selection of assemblies to lab test. Assemblies were selected based on cost, availability of materials, use of non-proprietary materials (when available), construction ease and speed, anticipated performance and paucity of existing test data. Section 6.3 | 49© 2019 Energy Studies in Buildings Laboratory, University of Oregon Energy Studies in Buildings Laboratory INDUSTRY FEEDBACK Dean Lewis, Engineer DCI-Engineers ( email response ) Below is a list of considerations for the industry in relation to acoustics with mass timber products: 1. What are the most thin assemblies which expose the CLT soffit which can achieve a STC & IIC rating of 50. Typically we are looking at 131mm 5PLY CLT panel 9 (note thickness is optimized with thin weak axis layers) with acoustic mat (typically from Maxxon) and 1-1/2” to 2” layer of gypcrete. Below are some sub- topics on this assembly a. Besides Maxxon are there any other products which can fulfill this need? b. What is the range in performance with 1-1/2” of gypcrete vs 2” of gypcrete? i. Does normal weight or lightweight concrete perform better? c. If we substitute an MPP plywood panel will need to confirm it performs similarly. 2. What are the risks of flanking between the CLT walls and floors. a. Are there similar risks with CLT floors and light frame walls (wood and CFS). b. Are there product suggestions which can help range performance, we know that Rothoblaas offers a lot of solutions. 3. How much can custom shapes of NLT or DLT enhance acoustics? This could really push mass timber to beat out steel and concrete in any office or school project. a. Also, if the NLT or DLT has its cavities stuffed with acoustical insulation, how much better performance do we achieve. Alex Zelaya, Architect Hacker ( survey response ) (Work on several office CLT projects.) Floor: 1 1/2” Concrete seems too thin and would likely crack - needs to be covered by flooring. Would be interesting to have mineral wool instead of concrete. James Woods, Engineer Glumac ( email response ) (Has done a lot of work with raised access floors and CLT) I am definitely interested in being involved, but our expertise is MEP and Lighting design so we don’t have much to say about the acoustics of the assemblies themselves (that’s a bit more architectural/acoustic consultant specific). Some topics I would expect to have some thoughts on are: - Designing for open/no ceilings/exposed services - Coordination of MEP penetrations - Energy efficiency/reduced carbon footprint potential of timber + MEP+Lighting system concepts - Moisture control through envelope for timber buildings - Is humidity control needed in timber buildings??? - Pressurization of the building? Etc! Evan Stravers, Architect SEA ( survey response ) (Worked at Path on Carbon 12) Floor: [5-ply with acoustic mat, concrete topping] also seems like a prototypical CLT floor assembly for future use. Would highly suggest this as a test, since additional flooring assemblies and adhesives to top this with also likely receive testing, and the results could be extrapolated. [5-ply with acoustic mat, concrete topping, underlayment, floating floor] is the closest to the main Carbon 12 floor assembly, and probably represents what architecture firms would ideally pursue from a look perspective moving forward, with exposed undersides and floating floor to match. Seems like this could be tested without the underlayment and flooring, and retested with those installed? [like above with additional topping] Like the Carbon12 floor slab with 2x the layering. Could represent a “cadillac” solution. Wall: [3-ply with rainscreen] Seems like a prototypical exterior CLT wall assembly for many applications. Would suggest. Section 6.3 | 50© 2019 Energy Studies in Buildings Laboratory, University of Oregon Energy Studies in Buildings Laboratory Juliette Grummon-Beale, Architect FFA ( email response ) (Two CLT projects on the boards) We have completed one project using CLT- a single story library in Boise, ID. We had a two story office project go on hold that was CLT. We are currently in the CD phase on a two-story police/public safety building that will have CLT floors and walls that essentially functions as an office. Would any of these qualify? For each of these projects, exposed CLT has been critical for aesthetics and showcasing a local Pacific NW resource. I believe the designers have thought CLT does double duty as a finish and structural system, but I am still unsure about how cost effective it is for a single or even two story project. Yes, acoustics have been tricky. We are even considering Structurecraft’s DLT product for an upcoming higher-ed project where we’d like exposed wood but just can’t get the acoustic separation required. The vibration design criteria has also been limiting since you can structurally span longer distances, but for acoustics and comfort you need to reduce the structural bay size. Most of our CLT projects have also gone the route of radiant heating, so the ceiling may be clean and have little mechanical. This does double duty since a topping slab is recommended for CLT floors. The exposed concrete along with the exposed wood has to be weighed with acoustics, so we’ve dropped in ACT clouds in areas like conference rooms. Randy McGee, Architect ZGF ( email response ) I am building a 3 story 1000 Sf CLT addition to my NW Portland residence. All CLT is 3 ply and exposed on the interior with an exterior rainscreen over semi-rigid insulation. All CLT fasteners are concealed. Very simple (except for the cantilever). The brewery we are working on in NW Portland will be receiving the CLT panels from DR Johnson in about two weeks for installation. Those panels vary from 3 ply to 7 ply. Again, all CLT is exposed on the interior with concealed fasteners. Exterior is Corten rainscreen over semi rigid insulation. Erica Fischer, PhD, PE, Engineering Professor, OSU (Structural concrete/ CLT hybrid diaphragms) ( email response ) We chose 2.5 inches because that is what was used in the seismic/dynamic tests performed by Andre Barbosa and Chris Higgins. We are using their same assembly, which was developed by SOM and OSU because it has been tested quite a bit, but not in fire. These fire tests will “complete the story” per se. The 2.5 inches is at the lower end of what you would want to use structurally for a composite floor. It is hard to rationalize a 1.5 inch concrete on CLT as structural. Below 2”-2.25”, the concrete is considered really a topping and not structural. We are putting reinforcement in the concrete, so it is going to be part of the structural system. You bring up a great point about the acoustical barrier. You are right in that it typically goes on top of the CLT. However, if we are drilling self-tapping screws through the acoustical barrier, we are weakening its effectiveness. We are not using an acoustical barrier in our tests. We are assuming (and we are aware of the magnitude of this assumption) that the acoustical barrier could go on top of the concrete. This way the screws are not going through the barrier and the concrete and CLT can be composite. In the PNW we use normal weight concrete which has a density of about 145 pcf, 150 pcf is assumed when including reinforcement. Other locations of the country have light weight aggregate that allow for lower density concrete. It is very difficult to get that aggregate in the PNW. Jake Ross, Engineer/ Acoustician Creative Acoustics NW ( phone conversation ) For CLT tests, would like to see: Bare structure (base case), solid ceiling with resilient channel ,resilient mat, kinetics noise control - for floor products, the thicker the resilient piece is, the more it can deflect, therefore better IIC. Bare structure 2 ceilings: Solid, resilient 2 floors : 1 thicker, 1 thinner As we improve IIC, STC will increase. The inverse is not usually true. INDUSTRY FEEDBACK Section 6.3 | 51© 2019 Energy Studies in Buildings Laboratory, University of Oregon Energy Studies in Buildings Laboratory Denis Blount, Engineer Arup (AIA Woodworks presentation on acoustics) ( survey response ) Denis worked as consultant on Framework project - Stuff in CLT handbook wasn’t always tested in a lab and they are finding numbers are off - Not a lot of data on built projects - Test data needs to be done in ISO or ASTM certified lab - Chunk of the testing out there has been done by manufacturers so questionable reliability - IBC requirement for multifamily is way too low - ICC recent report talks about houses built to the lowest common denominator of IBC has whole groups of people that are unhappy - Mass timber opportunity to re-establish baseline for multifamily prototypical assembly to improve people’s wellbeing - Hans Erik Blomgren at Katerra looked at doing away with wet trades using offsite fabrication. Found out that eliminating wet trades doesn’t save as much as first thought - Concrete massive topping was defacto solution - Now there is a lot more data available on floor assemblies using sheet goods - Great to get test data on MPP but since this is a proprietary product, its use might be limited - Nothing magic about resilient underlayment - Regupol is the “kleenex” of underlayments and not much difference in performance between these. - Stay away from woven fiber underlayments - There is flat rubber, dimpled and variations (e.g. GenieMat) Randy Waldeck, Engineer/ Acoustician CSDA Design Group (AIA Woodworks presentation on acoustics) ( email response ) In general, I can tell you that STC 50 and IIC 50 is the magic number for Building Code and other acoustical standards. So, at a minimum, we should focus on those assemblies that have achieved or are expected to achieve 50. Eric McDonnell, Engineer KPFF (Worked on several CLT projects includeing Framework and Albina Yard) ( conversation ) Eric gave feedback at Mass Timber meetup on acoustics regarding wall assembly - Need to use 5-lam vs proposed 3-lam in wall assembly due to 1 hour fire rating requirement. Zach Brehm, Contractor Swinerton (Construction project manager on CLT projects) ( email response ) Zach interested in finding generic assemblies that can have substitutions during bidding and feel comfortable that it will meet code. - Don’t use concrete unless structural. Interested in structural composite testing - Gypcrete achieves goal for less - Less fiber = more economical and desirable. 3 lam best or 5 lam if needed. Stay away from 7 lam - Plywood more expensive than osb - “sand is difficult to handle” - Haven’t seen adoption of CLT walls in Western US due to seismic rigidity - wood studs less than half the cost of clt - Need to test structural concrete floor assembly INDUSTRY FEEDBACK Section 6.4 | 52© 2019 Energy Studies in Buildings Laboratory, University of Oregon Energy Studies in Buildings Laboratory ACOUSTIC TESTING LAB SELECTION MATRIX 6.4 The selection of an acoustic testing facility for wall and floor assemblies involves a multi- factorial analysis of criteria. In addition to typical considerations of cost, lead time, shipping distance, procurement of materials (lab versus client), some additional criteria to consider that are specific to mass timber involve the ability to handle, maneuver and install large, heavy panels. Testing bed size is a significant factor in structuring the test since panels can be manufactured in various widths and transportation requirements and facility clear opening dimensions will determine whether a single panel will suffice or multiple panels need to be joined. Based on our international (Canada + USA) search of testing facilities and analysis of multiple criteria (see matrix), the decision was made to use the following ASTM-certified facilities: FLOOR PANEL TESTS Riverbank Acoustical Laboratories 1512 S Batavia Ave Geneva, IL 60134-3302 Tel: 630-232-0104 WALL PANEL TESTS USG Testing Services, Corporate Innovation Center 700 N.
