2 EXECUTIVE SUMMARY This document describes a transportation noise assessment performed for a proposed four-storey condominium development in Ottawa, Ontario. The buildings will rise 14 meters above local grade. Figure 1 illustrates a site plan with surrounding context. The major sources of roadway noise affecting the development is traffic along Fifth Avenue and Queen Elizabeth Drive. For clarity within this report, the north and south buildings have been labelled Building A and Building B, respectively. The assessment is based on: (i) theoretical noise prediction methods that conform to the Ministry of the Environment (MOE) and City of Ottawa requirements; (ii) noise level criteria as specified by the City of Ottawa s Environmental Noise Control Guidelines (ENCG); (iii) future vehicular traffic volumes based on the City of Ottawa s Official Plan roadway classifications; and (iv) architectural drawings received from Barry J. Hobin & Associates Architects Incorporated. The results of the current study indicate that noise levels due to roadway traffic over the site will range between 32 and 68 dba during the daytime period (07:00-23:00) and between 25 and 60 dba during the nighttime period (23:00-07:00). The highest traffic noise levels will occur along the east side of the development, nearest to Queen Elizabeth Drive. Minimum building construction in all areas is required to satisfy the Ontario Building Code (2012). In addition, the following Sound Transmission Class (STC) ratings are required for building components where noise levels exceed 65 dba (see Figures 4 and 5). (i) (ii) Bedroom Windows Bedroom windows on Building A facing east, and Building B facing east and south, will require a minimum STC of 31 All other bedroom windows are to satisfy Ontario Building Code (OBC 2012) requirements (i) (ii) Living Room Windows Living room windows on Building A facing east, and Building B facing east and south, will require a minimum STC of 26 All other living room windows are to satisfy Ontario Building Code (OBC 2012) requirements 370 Queen Elizabeth Drive: Transportation Noise Assessment i

3 (i) Exterior Walls Exterior wall components on the east façades require a minimum STC of 45 which will be achieved with brick cladding or an acoustical equivalent according to NRC test data 1 A review of window supplier literature indicates that the specified STC ratings can be achieved by a variety of window systems having a combination of glass thickness and inter-pane spacing. We have not specified any particular window configurations, as there are several manufacturers and various combinations of window components that will offer the necessary sound attenuation rating. However, it is the responsibility of the manufacturer to ensure that the specified window achieves the required STC. This can only be assured by using window configurations that have been certified by laboratory testing. The requirements for STC ratings assume that the remaining components of the building are constructed and installed according to the minimum standards of the Ontario Building Code. The specified STC requirements also apply to swinging and/or sliding patio doors. All specified building components will require review by a qualified acoustical engineer for conformance to the recommendations of this report prior to building permit application. In addition to upgraded windows, the installation of individual air conditioning units (or similar mechanical system) will be required for all units. Warning Clause (Type D 2 ) will also be required in all Agreements of Lease, Purchase and Sale, as outlined in Section 6 of this report. According to the ENCG, if occupants of the condominium are not afforded a common outdoor amenity area, any balconies/terraces are considered an outdoor living area provided they are at least 4 meters in depth, uncovered and exterior to the building. OLA receptors were placed at select terrace locations on the 4 th floor that met the aforementioned criteria. Although all balconies/terraces will have a 1.1 meter guardrail surrounding the exposed perimeter (as per OBC requirements), some guardrails have been architecturally designed using stone, while others are glass. Where noise levels on specific 4 th floor terraces are above the ENCG criteria, it is not architecturally feasible to replace the guardrail with a noise screen in excess of 1.1 meters in height. As such, for select terraces on the 4 th floor that currently incorporate a glass guardrail, it is recommended that a sealed glass screen of 1.1 meters in height be installed. Balconies/terraces that incorporate a stone guardrail do not require additional construction elements as this design is sufficient. 1 J.S. Bradley and J.A. Birta.

6 1. INTRODUCTION Gradient Wind Engineering Inc. (GWE) was retained by Bassi Construction Ltd. on behalf of to undertake a transportation noise assessment of a proposed condominium development in Ottawa, Ontario. This report summarizes the methodology, results and recommendations related to a roadway traffic noise. GWE s scope of work involved assessing exterior and interior noise levels generated by local roadway traffic. The assessment was performed on the basis of theoretical noise calculation methods conforming to the City of Ottawa 5 and Ministry of the Environment 6 guidelines. Noise calculations were based on architectural drawings received from Barry J. Hobin & Associates Architects Incorporated, with future traffic volumes corresponding to the City of Ottawa s Official Plan (OP) roadway classifications. 2. TERMS OF REFERENCE The focus of this transportation noise assessment is a proposed four-storey condominium. The development is located along Queen Elizabeth Drive, between Fourth Avenue and Fifth Avenue. The major sources of noise in the area is traffic along Fifth Avenue and Queen Elizabeth Drive. The site is surrounded with residential developments to the north, south and west. Figure 1 illustrates a complete site plan with surrounding context. For clarity within this report, the north and south buildings have been labelled Building A and Building B, respectively. Upon completion, the development will rise 14 meters above local grade. There are no common outdoor amenity areas. Most units have individual balconies/terraces. Only a select few terraces on the 4 th floor are deeper than 4 meters and are considered to be outdoor living areas (OLA) for the associated dwelling units, as there are no other common outdoor amenity spaces provided. 5 City of Ottawa Environmental Noise Control Guidelines, SS Wilson Associates, May 10, Ministry of the Environment Publication NPC Queen Elizabeth Drive: Transportation Noise Assessment 1

7 3. OBJECTIVES The main goals of this work are to: (i) calculate the future noise levels on the study building produced by local roadway traffic and (ii) ensure that interior noise levels do not exceed the allowable limits specified by the City of Ottawa s Environmental Noise Control Guidelines as outlined in Section 4.2 and 4.4 of this report. 4. METHODOLOGY 4.1 Background Noise can be defined as any obtrusive sound. It is created at a source, transmitted through a medium, such as air, and intercepted by a receiver. Noise may be characterized in terms of the power of the source or the sound pressure at a specific distance. While the power of a source is characteristic of that particular source, the sound pressure depends on the location of the receiver and the path that the noise takes to reach the receiver. Measurement of noise is based on the decibel unit, dba, which is a logarithmic ratio referenced to a standard noise level ( Pascals). The A suffix refers to a weighting scale, which better represents how the noise is perceived by the human ear. With this scale, a doubling of power results in a 3 dba increase in measured noise levels and is just perceptible to most people. An increase of 10 dba is often perceived to be twice as loud. 4.2 Roadway Traffic Noise Criteria for Roadway Traffic Noise For vehicle traffic, the equivalent sound energy level, L EQ, provides a measure of the time varying noise levels, which is well correlated with the annoyance of sound. It is defined as the continuous sound level, which has the same energy as a time varying noise level over a period of time. For roadways, the L EQ is commonly calculated on the basis of a 16-hour (L EQ16) daytime (07:00-23:00) / 8-hour (L EQ8) nighttime (23:00-07:00) split to assess its impact on residential buildings. The City of Ottawa s Environmental Noise Control Guidelines (ENCG) specifies that the recommended indoor noise limit range (that is relevant to this study) is 45 dba for living rooms and 40 dba for bedrooms, as listed in Table 1. Based on GWE s experience, more comfortable indoor noise levels should be targeted toward 42 dba and 37 dba respectively, to control peak noise and deficiencies in building envelope construction. 370 Queen Elizabeth Drive: Transportation Noise Assessment 2

In addition, when noise levels exceed the criteria outlined in Table 3, upgraded building components must be designed. 7 Adapted from ENCG Table Queen Elizabeth Drive: Transportation Noise Assessment 3

10 4.2.2 Roadway Traffic Volumes The ENCG dictates that noise calculations should consider future sound levels based on a roadway s classification at the mature state of development. Therefore, traffic volumes are based on the roadway classifications outlined in the City of Ottawa s Official Plan (OP) and Transportation Master Plan 10. Average Annual Daily Traffic (AADT) volumes are then based on data in Table 1.7 of the ENCG for each roadway classification. Alternatively, the MOE and common industry practice recommends using existing traffic volumes projected to exist ten years into the future with an average annual growth rate of 2% per year. Table 4 summarizes the AADT values used for each roadway included in this assessment. To ensure compliance with the reasonable worst-case situation, the following steps were taken: Recent traffic-count data was acquired (where applicable) from the City of Ottawa and the Ministry of Transportation, upon which a growth rate of 2% per year was applied and extrapolated to the year of 2024 Traffic volumes based on roadway classification at mature state of development were obtained from Table 1.7 of the ENCG. The Transportation Master Plan Affordable 2031 Roadway Network provides additional details on future roadway expansions. In all cases, the higher of the Official Plan versus projected values were used to calculate future noise levels. Table 4 summarizes the AADT values used for each roadway included in this assessment.

11 4.2.3 Theoretical Roadway Noise Predictions Noise predictions were performed with the aid of the Ministry of the Environment (MOE) computerized noise assessment program, STAMSON 5.04, for road and rail analysis. Appendix A includes the STAMSON 5.04 input and output data. Roadway noise calculations were performed by treating each road segment as separate line sources of noise, and by using existing building locations as noise barriers. In addition to the traffic volumes summarized in Table 4, theoretical noise predictions were based on the following parameters: Truck traffic on all roadways was taken to comprise 5% heavy trucks and 7% medium trucks The day/night split was taken to be 92% / 8% respectively for all streets Absorptive and reflective intermediate ground surfaces based on specific source-receiver path ground characteristics The study site was treated as having flat topography Noise receptors were strategically placed at 21 locations around the study area (see Figures 2 and 3). 4.3 Indoor Noise Calculations The difference between outdoor and indoor noise levels is the noise attenuation provided by the building envelope. According to common industry practice, complete walls and individual wall elements are rated according to the Sound Transmission Class (STC). The STC ratings of common residential walls built in conformance with the Ontario Building Code (2012) typically exceed STC 35, depending on exterior cladding, thickness and interior finish details. For example, brick veneered walls can achieve STC 55. Standard good quality double-glazed non-operable windows can have STC ratings ranging from 25 to 40 depending on the window manufacturer, pane thickness and inter-pane spacing. As previously mentioned, the windows are the known weak point in a partition. According to the ENCG, when daytime noise levels (from road and rail sources) at the plane of the window exceed 65 dba, calculations must be performed to evaluate the sound transmission quality of the building components to ensure acceptable indoor noise levels. The calculation procedure 11 considers: 11 Building Practice Note: Controlling Sound Transmission into Buildings by J.D.

12 Window type and area as a percentage of total room floor area Exterior wall type and area as a percentage of the total room floor area Acoustic absorption characteristics of the room Outdoor noise source type and approach geometry Indoor sound level criteria, which varies according to the intended use of a space Based on published research 12, exterior walls possess specific sound attenuation characteristics that are used as a basis for calculating the required STC ratings of windows in the same partition. Due to the limited information available at the time of the study, which was prepared for site plan approval, detailed floor layouts have not been finalized; therefore, detailed STC calculations could not be performed at this time. As a guideline, the anticipated STC requirements for windows have been estimated based on the overall noise reduction required for each intended use of space (STC = outdoor noise level targeted indoor noise level). 5. RESULTS AND DISCUSSION 5.1 Roadway Noise Levels Appendix A contains the complete set of input and output data from all STAMSON 5.04 calculations. The results of the roadway noise calculations are summarized in Table 5 below.

The highest noise level (i.e. 68 dba) occurs on the east side (Receptor 2), which is closest to Queen Elizabeth Drive. 5.2 STC Requirements The noise levels predicted due to road traffic exceed the criteria listed in the ENCG for building components. As discussed in Section 4.3 the anticipated STC requirements for windows have been estimated based on the overall noise reduction required for each intended use of space (STC = outdoor noise level targeted indoor noise level). As per City of Ottawa requirements, detailed STC calculations will be required to be completed prior to building permit application for each unit type. The STC requirements for windows are summarized below for various units within the development (see Figures 4 and 5): 370 Queen Elizabeth Drive: Transportation Noise Assessment 8

OLA receptors were placed at select terrace locations on the 4 th floor that met the aforementioned criteria. Although all balconies/terraces will have a 1.1 meter guardrail surrounding the exposed perimeter (as per OBC requirements), some guardrails have been architecturally designed using stone, while others are glass.

As such, for terraces on the 4 th floor that currently incorporate a glass guardrail, it is recommended that a sealed glass screen of 1.1 meters in height be installed. Balconies/terraces that incorporate a stone guardrail do not require additional construction elements as this design is sufficient. Table 7 summarises the noise impacts on the outdoor living areas.

As the floor plans have not currently been finalized, it is not possible to apply specific clauses to individual units. Table 8 below outlines the applicable Warning Clause for individual receptor locations. It is recommended that once floor plans have been finalized, each unit be referenced to the appropriate receptor for the specific Warning Clause. 370 Queen Elizabeth Drive: Transportation Noise Assessment 10

CONCLUSIONS AND RECOMMENDATIONS The results of the current study indicate that noise levels due to roadway traffic over the site will range between 32 and 68 dba during the daytime period (07:00-23:00) and between 25 and 60 dba during the nighttime period (23:00-07:00). The highest traffic noise levels will occur along the east side of the development, nearest to Queen Elizabeth Drive. Minimum building construction in all areas is required to satisfy the Ontario Building Code (2012). In addition, the following Sound Transmission Class (STC) ratings are required for building components where noise levels exceed 65 dba (see Figures 4 and 5).

17 (i) Exterior Walls Exterior wall components on the east façades require a minimum STC of 45 which will be achieved with brick cladding or an acoustical equivalent according to NRC test data 14 A review of window supplier literature indicates that the specified STC ratings can be achieved by a variety of window systems having a combination of glass thickness and inter-pane spacing. We have not specified any particular window configurations, as there are several manufacturers and various combinations of window components that will offer the necessary sound attenuation rating. However, it is the responsibility of the manufacturer to ensure that the specified window achieves the required STC. This can only be assured by using window configurations that have been certified by laboratory testing. The requirements for STC ratings assume that the remaining components of the building are constructed and installed according to the minimum standards of the Ontario Building Code. The specified STC requirements also apply to swinging and/or sliding patio doors. All specified building components will require review by a qualified acoustical engineer for conformance to the recommendations of this report prior to building permit application. In addition to upgraded windows, the installation of individual air conditioning units (or similar mechanical system) will be required for all units. The following Warning Clause (Type D 15 ) will be required in all Agreements of Lease, Purchase and Sale for all units: Dwelling units in this building have been supplied with central air conditioning which will allow windows and exterior doors to remain closed, thereby ensuring that the indoor sound levels are within the City of Ottawa s and the Ministry of the Environment s noise criteria. According to the ENCG, if occupants of the condominium are not afforded a common outdoor amenity area, any balconies/terraces are considered an outdoor living area provided they are at least 4 meters in depth, uncovered and exterior to the building. OLA receptors were placed at select terrace locations on the 4 th floor that met the aforementioned criteria. Although all balconies/terraces will have a 1.1 meter guardrail surrounding the exposed perimeter (as per OBC Requirements), some guardrails have been 14 J.S. Bradley and J.A. Birta.

18 architecturally designed using stone, while others are glass. Where noise levels on specific terraces on the 4 th floor are above the ENCG criteria, it is not architecturally feasible to replace the guardrail with a noise screen in excess of 1.1 meters in height. As such, for terraces on the 4 th floor that currently incorporate a glass guardrail, it is recommended that a sealed glass screen of 1.1 meters in height be installed. The screen must have no embedded gaps in the construction. Balconies/terraces that incorporate a stone guardrail do not require additional construction elements as this design is sufficient. Furthermore, Warning Clauses Type A 16 and Type B 17 will be required for select units, as tabulated in Table 8 in Section 5.3. Once floor plans have been finalized, specific Warning Clauses can be applied to individual units. Warning Clause Type A: Purchasers/tenants are advised that sound levels due to increasing road traffic may occasionally interfere with some activities of the dwelling occupants as the sound levels exceed the City s and the Ministry of the Environment s noise criteria. Warning Clause Type B: Purchasers/tenants are advised that despite the inclusion of noise control features in the development and within the building units, sound levels due to increasing road traffic may on occasions interfere with some activities of the dwelling occupants as the sound levels exceed the City s and the Ministry of the Environment s noise criteria. Additionally, the following restrictive covenant shall also be included in all Agreements of Lease, Purchase and Sale: The Transferee covenants with the Transferor that the above clause, verbatim, shall be included in all subsequent Agreements of Purchase and Sale and deeds conveying the lands described herein, which shall run with the said lands and is for the benefit of the subsequent owners of the said lands and the owner of the adjacent road. 16 Ministry of the Environment Publication NPC Ministry of the Environment Publication NPC Queen Elizabeth Drive: Transportation Noise Assessment 13
