This course is registered with AIA CES for continuing professional education. As such, it does not include content that may be deemed or construed to be an approval or endorsement by the AIA of any material of construction or any method or manner of handling, using, distributing, or dealing in any material or product. Questions related to specific materials, methods, and services will be addressed at the conclusion of this presentation.

3 Urban Acoustics Course Description As with any issue of building performance, the acoustics of a mixed-use wood-frame structure can be designed to meet or far exceed minimal requirements. It is the responsibility of the design team to determine acoustical expectations for the project and meet them within the available budget. Through the use of case studies, this fast-paced, interactive session will explore how multistory wood systems can be used to meet acoustical privacy goals. Discussion will focus on the detailing and construction of units, and how consideration of the construction process can help keep acoustical costs down. With the objective of providing implementable solutions, the session will include construction details and photos showing what has and hasn t worked in actual buildings.

4 At the end of this program, participants will be able to: - Evaluate the acoustical impact of ICC Building Code vs. Residential Expectations - Develop cost effective / acoustically centric space planning ideas for wood frame design - Produce practical and constructible acoustical isolation detailing for wood frame design - Identify common acoustical compromises during construction

12 Urban Acoustics The Building Code

13 Our Goal Control the Transfer of Noise!

14 Acoustical Expectations Luxury? Market Rate? Entry Level? Slide 16

15 FHA Rules of Thumb from 1962 NOTE THIS IS NOT A CODE, IT HAS BECOME the DE FACTO STANDARD BUT NOT CODE Entry Level Housing STC 50 / IIC 50 (STC /IIC 48)* Market Rate Housing STC 55 / IIC 55 (STC/IIC 52)* Luxury Rate Housing STC 60+ / IIC 60+ (STC/IIC 55)* IIC 60+ very hard to achieve with wood or tile surfaces * Actual 1962 values adjust when IBC set 50 as minimum

16 ICC G Guideline for Acoustics STILL NOT A CODE, IT IS FROM THE ICC FROM WHAT APPEARS TO BE A RESEARCH PAPER FROM THE INTERNET! Acceptable Performance Grade B Performance 55 / 52 (Laboratory / Field) Airborne - STC / NNIC Impact - IIC / NISR Preferred Performance Grade A Performance 60 / 57 (Laboratory / Field) Airborne - STC / NNIC Impact - IIC / NISR

17 Exterior to Interior

18 Land Use Compatibility For Community Noise Land Use Category Exterior Day/Night Noise Levels (Ldn, dba) Single Family Multi Family Motel, Hotels Outside Use Normally Acceptable Conditionally Acceptable Normally Unacceptable Clearly Unacceptable

19 Mixed Use Bar to Housing

20 Commercial to Residential Not Addressed by Building Code - Implied at 45 dba /Ldn (Interior Noise Criterion) - Enforced as Nuisance Complaints - Enforced by Local Codes THIS IS CHANGING THE IgCC IS PLACING LIMITS ON COMMERCIAL TO RESIDENTIAL

59 70+ Cross-Laminated Timber

60 Cross-Laminated Timber ACOUSTICALLY STILL REALLY NEW We Need More Test Data In absence of test data we compare 70+ to known acoustical systems

61 Cross-Laminated Timber "Volume generally assumed for the density of hardened concrete is 150 lb./ft 3. (2400 kg/m 3 ) McGraw-Hill Encyclopedia of Science and Technology.

62 Cross-Laminated Timber 6 inch thick 20 lb./ft 3. CLT Same Mass as 1.6 inch thick Concrete Based on Acoustics Mass Law STC Rating about 38 STC
