2 EXECUTIVE SUMMARY This document describes an environmental noise assessment performed for a proposed mixed-use development consisting of two adjoining 27 and 32-storey towers atop a five-storey podium. The development is located at the northeast intersection of Chapel Street and Rideau Street, in Ottawa, Ontario. For the purposes of clarity within this report, we have assigned each tower a letter. Tower A is nearest to Beausoleil Drive, while Tower B is nearest to Rideau Street. The major sources of noise in the area are from roadway traffic along Rideau Street and Beausoleil Drive. The site is surrounded on all sides with mixed-use land, specifically commercial, institutional and residential. Figure 1 illustrates a complete site plan with surrounding context. 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 right of way allowances; and (iv) architectural drawings received from B+H Architects. The results of the current study indicate that noise levels due to roadway traffic over the site will range between 34 and 68 dba during the daytime period (07:00-23:00) and between 26 and 62 dba during the nighttime period (23:00-07:00). The highest traffic noise levels will occur along the south façade of Tower B, nearest to Rideau Street. Minimum building construction in all areas is required to satisfy the Ontario Building Code (2006). As described in Section 5.2, upgraded building components with higher Sound Transmission Class (STC) ratings will be required for building components on the south façade of Tower B, where noise levels exceed 65 dba (see Figure 4). 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 Chapel Street: Roadway Traffic Noise Assessment i

3 In addition to upgraded windows, the installation of individual air conditioning units (or similar mechanical ventilation systems) will be required for all south facing units in Tower B. Warning Clause (Type D 1 ) will also be required in all Agreements of Lease, Purchase and Sale for all south facing units in Tower B, as outlined in Section 5 of this report. The installation of forced air heating with provisions for central air conditioning units (or similar mechanical ventilation systems) will be required for all remaining units (EXC: Tower B north facing units). Warning Clause (Type C 2 ) will be required in all Agreements of Lease, Purchase and Sale for all remaining units (EXC: Tower B north facing units), as outlined in Section 5 of this report. As noise levels on the 6 th floor terrace were found to be less than 55 dba, noise barriers are not required for the outdoor living areas. 1 Ministry of the Environment Publication NPC ibid Chapel Street: Roadway Traffic Noise Assessment ii

5 1. INTRODUCTION Gradient Wind Engineering Inc. (GWE) was retained by to undertake a roadway traffic noise study of the proposed mixed-use development at Chapel Street in Ottawa, Ontario. This report summarizes the methodology, results and recommendations related to a roadway traffic noise assessment. 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 3 and Ministry of the Environment 4 guidelines. Noise calculations were based on architectural drawings received from B+H Architects with future traffic volumes corresponding to the City of Ottawa s Official Plan (OP). 2. TERMS OF REFERENCE The focus of this roadway traffic noise assessment is a proposed development consisting of two adjoining 27 and 32-storey towers atop a five-storey podium. The development is located at the northeast intersection of Chapel Street and Rideau Street. For the purposes of clarity within this report, we have assigned each tower a letter. Tower A is nearest to Beausoleil Drive, while Tower B is nearest to Rideau Street. The major sources of noise in the area are from roadway traffic along Rideau Street and Beausoleil Drive. The site is surrounded on all sides with mixed-use land, specifically commercial, institutional and residential. Figure 1 illustrates a complete site plan with surrounding context. Upon completion, Tower A will rise approximately 98 meters above Beausoleil Drive, and Tower B will rise approximately 115 meters above Rideau Street. The ground floors will house commercial and residential amenity space, the 2 nd floor will house commercial and residential space, and floors 3-5 will house parking and residential space. The remaining floors occupy residential space only. A large 6 th floor terrace is located atop the five-storey podium. This terrace is considered as an outdoor living area, as per the MOE guidelines. 3 City of Ottawa Environmental Noise Control Guidelines, SS Wilson Associates, May 10, Ministry of the Environment Publication NPC Chapel Street: Roadway Traffic Noise Assessment Page 1

6 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 Sections 4.2 and 4.3 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 ranges (that are relevant to this study) are 50 dba for retail stores, 45 dba for living and dining areas and 40 dba for sleeping quarters of residences, as listed in Table 1. Based on GWE s experience, more comfortable indoor noise levels should be targeted toward 42 dba and 37 dba (for living rooms and bedrooms, respectively) to control peak noise and deficiencies in building envelope construction Chapel Street: Roadway Traffic Noise Assessment Page 2

When noise levels at these areas exceed the criteria outlined in Table 2, specific outdoor, ventilation and warning clause requirements may apply. In addition, when noise levels exceed the criteria outlined in Table 3, upgraded building components must be designed Chapel Street: Roadway Traffic Noise Assessment Page 3

9 4.2.2 Roadway Traffic Volumes For future traffic noise predictions, the MOE document NPC-300 requires the use of the Annual Average Daily Traffic (AADT) volumes, projected to exist ten years into the future, with an average annual growth rate of 2% per year. In contrast, the City of Ottawa s ENCG requires that the AADT volumes should be based on roadway allowances, which are defined by the Right of Way (ROW) protection values identified in the City of Ottawa s Official Plan (OP) for specific roadways. To ensure compliance with the reasonable worst case situation, the following steps were taken: Recent counted traffic data were acquired from the City of Ottawa upon which a growth rate of 2% per year was applied and extrapolated to the year of 2024 Traffic volumes based on roadway ROW values were obtained from the City of Ottawa Official Plan 5 (Annex 1 Road Classification and Rights of Way). For roadways where the ROW information was unavailable, the designation was assumed based on the size of the existing road and available traffic information. In all cases, the higher of the OP versus projected values were used to calculate future noise levels. Table 4 (below) summarizes the AADT values used for each roadway included in this assessment. TABLE 4: ROADWAY TRAFFIC DATA Roadway Roadway Class Speed Limit (km/h) Official Plan AADT Available Traffic AADT From Count Year of Traffic AADT Projected 2024 AADT Rideau Street 2-UAU 50 15,000 13, ,046 Beausoleil Drive 2-UCU 40 8,000 N/A N/A N/A Chapel Street 2-UCU 40 8,000 N/A N/A N/A 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 Chapel Street: Roadway Traffic Noise Assessment Page 5

10 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 2, 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, as per ENCG requirements for noise level predictions 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 or gentle sloping topography Noise receptors were strategically placed at 30 locations around the study area (see Figures 2 and 3). 4.3 Indoor Noise Calculations When calculations reveal that outdoor noise levels are sufficiently high as to require investigation of indoor noise levels, calculations are performed to verify the Sound Transmission Class (STC) requirements for building components. 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 (2006) 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 NPC-300, 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 6 considers: 6 Building Practice Note: Controlling Sound Transmission into Buildings by J.D.

Due to the limited information available at the time of the study, which was prepared for site plan approval, detailed floor layouts and building elevations 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 levels). 5. RESULTS AND DISCUSSION Outdoor noise levels are summarized in Section 5.1 and STC requirements to achieve targeted indoor noise level criteria are discussed in Section 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. 7 CMHC, Road & Rail Noise: Effects on Housing Chapel Street: Roadway Traffic Noise Assessment Page 7

13 The results of the current analysis indicate that noise levels will range between 34 and 68 dba during the daytime period (07:00-23:00) and between 26 and 62 dba during the nighttime period (23:00-07:00). The highest noise level (i.e. 68 dba) occurs along the south façade of Tower B, which is closest to Rideau Street. As noise levels on the 6 th floor terrace were found to be less than 55 dba, noise barriers are not required for the outdoor living areas. 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 levels). 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 the windows are summarized below for various units within the development (see Figure 4): Bedroom Windows (i) Bedroom windows facing south on Tower B will require a minimum STC of 31 Living Room Windows (i) Living room windows facing south on Tower B will require a minimum STC of 26 (i) Exterior Walls Exterior wall components require a minimum STC of 45 which will be achieved with brick cladding or an acoustical equivalent according to NRC test data 8 8 J.S.

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. Results of the calculations also indicate that all south facing units in Tower B will require central air conditioning (or similar mechanical ventilation systems), which will allow occupants to keep windows closed and maintain a comfortable living environment. All remaining units (EXC: Tower B north facing units) will require forced air heating with provisions for central air conditioning (or similar mechanical ventilation systems). In addition to ventilation requirements, Warning Clauses will also be required be placed on all Lease, Purchase and Sale Agreements, as summarized in Table 9 below.

15 6. CONCLUSIONS AND RECOMMENDATIONS The results of the current study indicate that noise levels due to roadway traffic over the site will range between 34 and 68 dba during the daytime period (07:00-23:00) and between 26 and 62 dba during the nighttime period (23:00-07:00). The highest roadway traffic noise levels will occur along the south façade of Tower B, nearest to Rideau Street. Minimum building construction in all areas is required to satisfy the Ontario Building Code (2006). In addition, building components where noise levels exceed 65 dba will require higher Sound Transmission Class (STC) ratings as described in section 5.2 and illustrated on Figure 4. 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 ventilation systems) will be required for all south facing units in Tower B. The following Warning Clause (Type D 9 ) in all Agreements of Lease, Purchase and Sale will be required for all south facing units in Tower B: 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. The installation of forced air heating with provisions for central air conditioning units (or similar mechanical ventilation systems) will be required for all remaining units (EXC: Tower B north facing units). The following Warning Clause (Type C 10 ) in all Agreements of Lease, Purchase and Sale will be required for all remaining units (EXC: Tower B north facing units): 9 Ministry of the Environment Publication NPC ibid Chapel Street: Roadway Traffic Noise Assessment Page 11
