TC UNITED GROUP – 852 Bank Street

Traffic & Stationary Source Noise Control Study for Site Plan Approval Dear Ryan, The proposed commercial development at 852 Bank Street requires a Noise Control Study for site plan approval which consists of two parts: a traffic noise study and an environmental noise study of the stationary noise sources on the building. This report has been prepared in accordance to the City of Ottawa’s Environmental Noise Control Guidelines (ENCG). Part A of the report discusses the results of our traffic noise study. The City of Ottawa requires such a study to ensure that the noise levels inside the living spaces are below the stated limit. If the traffic noise at the plane of a window exceeds 65 dBA, the building components must be analyzed to ensure that the indoor noise level requirements are met. These level requirements are a maximum of 45 dBA between 7:00am and 11:00pm inside rooms such as living rooms, kitchens and dining rooms and 40 dBA at night between 11:00pm and 7:00am in bedrooms. To ensure that noise levels inside the units meet the requirements, we have made recommendations to the envelope construction of proposed construction at 852 Bank St. Part B of the report pertains to the environmental noise assessment of the stationary noise sources of the proposed development. Using architectural plans, we have created a 3D acoustical model of the development and have calculated the worst-case predicted noise levels at the nearest noise-sensitive buildings: The Free Methodist Church at 2 Monk St. and the residential units at 149 Fifth Avenue and 9-13 Monk Street. If you have any questions or concerns, please feel free to us. Sincerely, Alexandre Fortier, M.Sc, Acoustical Consultant

Introduction State of the Art Acoustik Inc. was commissioned by TC United to complete a noise control study as part of a site plan application for the proposed residential development at 852 Bank Street in Ottawa, Ontario, which consists of one 4 storey building. The first part of this study (A) analyses the traffic noise at the building. The study has been completed for all major roadways within 100 meters of the building, all railways or highways within 250 meters of the building and all freeways or provincial highways within 500 meters of the building, as required per the City of Ottawa’s Environmental Noise Control Guidelines (ENCG), section 1.4. The second part of the study (B) analyses the predicted environmental noise caused by the 4 major sources on site to nearby noise sensitive properties. We provide recommendations in order to meet the environmental noise regulations set out by ENCG for environmental noise.

A. Traffic Noise Study

1.0 Project Description The proposed development consists of a 4 storey building located at the South-West corner of the intersection of Bank St. and 5th Ave. The building will contain retail space on the ground floor, office space on the 2nd floor and residential units on the 3rd and 4th floors. The nearby roads considered in this analysis are Bank St. and 5th Ave. The Queensway is beyond 500 meters from the site and therefore does not need to be analyzed in this traffic noise study.

2.0 Site Plan Figure A1 on the following page shows a site plan view of the proposed development indicating the two road noise sources and the two points of reception (POR) used in the noise source models that follow. The Point of reception (POR) was chosen as the area that represents the worst case scenario for traffic noise, at the corner of Bank and 5th avenue. By planning for this area, the envelope of the building will provide sufficient sound isolation for every residential unit:

3.0 Procedure Used to Assess Noise Impact This assessment uses the City of Ottawa - Environmental Noise Control Guidelines (ENCG), dated May 10, 2006, to assess and mitigate noise from roads, transit ways, railways and aircraft. Summarized in Table A1 below are the maximum road noise levels for indoor areas that apply to this development, taken from table 1.6 of the ENCG.

Time Indoor Leq Levels (dBA) Class 1, 2 & 3 Areas

Road Traffic/Light Rail Noise Level (dBA)

07:00 – 23:00 45 for living/dining areas of residences

23:00 – 7:00 40 for bedrooms Table A1 – Criteria for Indoor Area Road Noise Levels

The ENCG states that noise control studies are to be prepared when the indoor area is within the follow setback distances from the road, highway and railway noise sources:

100m from an arterial road or a major collector

500m from a 400-series provincial highway

250m for a highway or Light Rail Transit system corridor This noise control study is required as the proposed development is less than 100m from both Bank St. and 5th Ave. There are no other roadways that need to be considered for this development.

4.0 Noise Attenuation Requirements This section outlines the required noise control measures and warning clauses and when to apply them, as stipulated by the ENCG for placement within purchase agreements. If sound levels are predicted to be less than the specified criteria no attenuation measures are required on the part of the proponent. If the predicted noise exceeds the criteria, the City of Ottawa recommends several attenuation measures. These attenuation measures may include any or all of the following:

construction of a noise barrier wall and/or berm;

installation of a forced air ventilation system with provision for central air;

installation of central air;

acoustically selected building façade components

http://www.sota.ca/



Where excessive noise levels may adversely affect property or its use, the ENCG requires notices in the form of a Warning Clause to be placed on title in order to alert the buyer or renter of a possible environmental noise condition or a limitation on his/her property rights. The notices on title must be included in the Development Agreement(s) and in the Agreement(s) or Offer(s) of Purchase and Sale. Table A2 outlines the noise attenuation measures required for various noise levels predicted at the Plane of Window (POW) of the proposed development (from ENCG Tables 1.8 and 1.10)

Table A3 summarizes the warning clauses referred to above in table A2 (from ENCG Table 1.13).

TYPE WARNING CLAUSE

Type A “Purchasers/tenants are advised that sound levels due to increasing (road) (Transitway) (rail) (air) traffic may occasionally interfere with some activities of the dwelling occupants as the sound levels exceed the sound level limits of the Municipality and the Ministry of the Environment.”

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) (Transitway) (rail) (air) traffic may on occasions interfere with some activities of the dwelling occupants as the sound levels exceed the sound level limits of the Municipality and the Ministry of the Environment.”

Type C “This dwelling unit has been designed with the provision for adding central air conditioning at the occupant’s discretion. Installation of central air conditioning by the occupant in low and medium density developments will allow windows and exterior doors to remain closed, thereby ensuring that the indoor sound levels are within the sound level limits of the Municipality and the Ministry of the Environment.”

Type D “This dwelling unit has been supplied with a central air conditioning system which will allow windows and exterior doors to remain closed, thereby ensuring that the indoor sound levels are within the sound level limits of the Municipality and the Ministry of the Environment.”

Type E “Purchasers/tenants are advised that due to the proximity of the adjacent industry (facility) (utility), sound levels from the industry (facility) (utility) may at times be audible.”

1 These warnings are the standard clauses from the MOE and are subject to change at the discretion of the City, Airport Authority, CN or other applicable agencies, as required. Additional warnings pertaining to aircraft noise are also included on page D-4

Table A3 - Warning Clause Statements from the City of Ottawa

5.0 Building Component Assessment (AIF Analysis) As mentioned in the previous section and according to Table 1.8 of the ENCG, when noise levels exceed 65 dBA at the Plane of Windows (POW) of a living area (daytime) or 60 dBA at the POW of a bedroom (nighttime) the exterior cladding system of the building envelope must be acoustically designed to ensure the indoor noise criteria is achieved. The City of Ottawa recognizes the Acoustic Insulation Factor (AIF1) method as an appropriate analysis technique. To comply with the City of Ottawa policies, the building envelope will require a minimum AIF rating to provide the indoor noise level required for living, dining and bedrooms of residential dwellings as described below. The City of Ottawa’s ENCG outlines the following maximum indoor Leq limits:

http://www.sota.ca/



maximum daytime indoor Leq for living spaces should be 45 dBA

maximum nightime indoor Leq for bedrooms should be 40 dBA For the overall exterior wall of any room, the required AIF for road and rail transportation noise is: Required AIF = Outside Leq - Indoor Leq (Req) + 2dB (1)

When the exterior is built up of multiple components, then the AIF required of each component is determined by the following equation1: Required AIF = Outside Leq - Indoor Leq (Req) + 10 log10 (Number of Components) + 2dB (2)

The required AIF is based on the Outside Leq, Indoor Leq required and the total number of exterior façade components. The AIF method allows for the number of components to be reduced if any component significantly exceeds the required AIF1: “If the AIF of any component exceed the required AIF by 10 or more, the calculation should be repeated for the other components with the ‘total number of components’ reduced by one. This reduction in the number of components lowers the required AIF for the others.”

6.0 Road Traffic Information For this study, the major noise sources considered are roads. The sources considered are:

1) Bank Street 2) 5th Avenue

Table 4 summarizes the roadway’s parameters obtained by Table 1.7, p. 15 of The City of Ottawa Environmental Noise Control Guidelines - Planning and Growth Management Department , “Traffic and Road Parameters to be used for Sound Level Prediction” for the respective roadway class.

Table A4 – Summary of Major Roadway Noise Sources

7.0 Procedure Used for Roadway Noise Analysis In order to calculate the road noise impact at the proposed development, we utilized the Ministry of Environment’s STAMSON modeling software version 5.04. This program allows us to input variables of a road or railway such as traffic volume, types of vehicles, speed, barrier locations and topography to find the environmental noise impact at a point of reception a given distance away.

8.0 Parameters Used for Analysis The parameters used in STAMSON to assess the noise impact at the point of reception are shown in Table A5.

9.0 Road Noise Levels and Required Measures The following table summarizes the predicted sound pressure levels at the point of reception, from the results of the STAMSON environmental noise software (Appendix).

http://www.sota.ca/



Table A6 – Predicted Road Noise at the Point of Reception

Table A6 shows that the predicted sound levels at POR1 from Bank Street and 5th Avenue exceed 65 dBA during the day and 60 dBA at night. It is therefore required to analyze the building components to ensure that the indoor sound level criteria are met at this location. As this POR represents the worst case of noise impact for the entire building, ensuring that the indoor level criteria are met at this location will ensure that they are met for the entire building.

10.0 Exterior Building Component Analysis

At the time of this study, the construction of the envelope components of the proposed development at 852 Bank St. is unknown. Therefore, in this section we will make recommendations for the wall and window assembly based on the AIF calculations.

11.0 Building Components and Room Dimensions The current design of the building façade is made up of 2 components:

1) Glazing 2) Exterior Wall

The POR selected corresponds to Unit 5 at the northern corner of the building, on the third floor. This unit contains both a living space and a bedroom at the corner of Bank St. and 5th Ave. Therefore, we have verified the AIF requirements for both spaces and provide a recommendation based on the most stringent of the two. This analysis follows. The calculation of AIF for each building component depends on the ratio of the area of a given component on the exterior to the total floor area of the corresponding interior room. Using architectural drawings dated October 5th 2015, and AutoCAD building elevations, we have determined the dimensions of the living space and bedroom of Unit 5 (the POR). The areas of the exterior wall components and floor area of the unit are given in Table A7 below:

Table A7 – Areas of Exterior Building Components and Floor Area

12.0 Required Overall AIF Using equation (1) , from section 5, the required overall AIFs for the exterior wall are calculated as follows, allowing for the possibility of noise-sensitive uses requiring an indoor level of 45 dBA during the day (for the living space) and 40 dBA at night (for the bedroom: Required AIF Living Space = 72 (Outside Leq) – 45 (Required Indoor Leq) + 10log10(2) + 2 = 32 Required AIF Bedroom = 65 (Outside Leq) – 40 (Required Indoor Leq) + 10log10(2) + 2 = 30 Higher AIF corresponds to a greater need for sound isolation. As the construction types for the wall and glazing are dependent on AIF and overall area (as shown in Table A7), we will determine the required compositions for the bedroom and the living space and the component construction with the higher sound transmission loss will be selected for the building envelope.

13.0 Exterior Construction Requirements Based on Minimum AIF The minimum AIF of 32 dictates the overall window and wall construction. If this minimum AIF is met, the building façade construction will be adequate to meet the indoor sound level requirement for noise-sensitive land uses at all points on the proposed building at 852 Bank St. Using the calculated AIF; the overall window and wall to floor area; and tables 6.2 and 6.1 of the Canadian Mortgage and Housing Corporation, Road and Rail Noise: Effects on Housing publication, we find the glazing and wall construction that is required. Table A8 below summarizes the required compositions.

The wall construction in Table A9 is found in the Canadian Mortgage and Housing Corporation, Road and Rail Noise: Effects on Housing publication. This wall construction is outdated and does not represent a typical, present day, envelope. Using table A10, taken from the Canadian Mortgage and Housing Corporation, Road and Rail Noise: Effects on Housing publication, gives us a corresponding STC for a given AIF. With this table we can determine the corresponding Sound Transmission Class (STC) of this wall to be approximately 35.

It is our understanding that an envelope with a Stucco type finish is desired for the building. The following wall type has an STC rating of 38 and can be used as the exterior wall.

STC 38 Stucco (EIF) Finish Wall

13mm gypsum 140mm stud (400 O/C)

152mm glass fibre insulation 11mm oriented strand board

0.7mm building paper 25mm expanded polystyrene

6mm EIF Table A11 – AIF 32 Stucco Wall Construction for a wall to floor area of 31%

Another option, if the glazing construction is too costly, is to increase the AIF of the wall by at least 10 points, this will reduce the glazing AIF requirement. When calculating the AIF for each component, if one of the components is 10 points higher than what is required, that component may be ignored when calculating the AIF of the other components. In this case, the equation for AIF for the windows becomes: Required AIF Living Space = 72 (Outside Leq) – 45 (Required Indoor Leq) + 2 = 30 The glazing construction could then be reduced to the following: 3mm glass + minimum 6mm airspace + 3mm glass. An example wall type that would allow this glazing would be the following:

14.0 Summary of Required Measures As the traffic noise level from Bank Street will exceed 65 dBA at the North corner of the building at 852 Bank St., the Warning Clause Type ‘D’ must be included in the Development Agreement(s) and in the Agreement(s) or Offer(s) of Purchase and Sale for each unit: Warning Clause Type ‘D’ “This dwelling unit has been supplied with a central air conditioning system which will allow windows and exterior doors to remain closed, thereby ensuring that the indoor sound levels are within the sound level limits of the Municipality and the Ministry of the Environment.”

15.0 Summary of Recommendations To meet the indoor sound level requirements for living spaces, the wall and glazing assemblies must be chosen to meet the required AIF. The two options to achieve this are as follow:

Use a wall that meets AIF 32, such as the Stucco wall type suggested in section 13.0 and a 4mm + 13mm airspace + 4mm glazing assembly.

OR

If the wall is increased to at least AIF 42, the glazing assembly may be reduced to: 3mm glass + minimum 6mm airspace + 3mm glass.

16.0 Conclusion Based on our traffic noise level predictions for the proposed commercial development at 852 Bank St., choosing the glazing and wall assembly recommended in section 15.0 will ensure that the indoor sound level requirements are met for all living areas. The Warning Clause Type ‘D’ regarding central air conditioning must be provided in the purchase/rental agreement for each unit, as per the City of Ottawa’s Environmental Noise Control Guidelines.

B. Stationary Source Environmental Noise Study

1.0 Project Description The development at 852 Bank St. will be located in an area with a mix of commercial and residential buildings. Due to the buildings’ proximity to local residences, this environmental noise assessment will determine whether the development adheres to the City of Ottawa’s Environmental Noise Control Guidelines (ENCG). The guidelines state that the total sound pressure level from all mechanical equipment must be below 45 dBA SPL, or the existing background noise level (whichever is higher), at the plane of a bedroom window between the hours of 23:00-07:00. This assessment assumes the mechanical equipment operates 24 hours a day, 7 days a week. There are 2 Rooftop Units and 2 Parking Exhaust Fans on the building, for a total of 4 noise sources that are considered for this assessment. The nearest Points of Reception are the Free Methodist Church at 2 Monk St., approximately 50m to the West, and the residential units at 149 Fifth Avenue and 9-13 Monk Street, 40m to the north and 30m to the south, respectively. These noise sources are proposed by the mechanical engineer for the new development. If any of the noise sources change or if other significant noise sources are added to the building, this report should be revalidated, as any additional sources could modify the results of the report.

2.0 Site Plan and Scaled Area Location Plan Figure B1 on the following page shows a site plan view of the proposed development, obtained from the city of Ottawa geo Ottawa map service, as well as the three nearest Points of Reception.

2.1 Noise Control Guidelines Table 1.12 of The City of Ottawa Environmental Noise Control Guidelines (ENCG) gives sound level criteria for new potential sources of stationary noise in proximity to existing noise-sensitive land uses. The criteria are dependent on the type of area the receiver lies in, with the various classes described in the summary of Table 1.1 in the ENCG. The proposed commercial building at 852 Bank St. falls into the category of a Class 1 area, which is defined as having an acoustical environment representative of a major urban area in the City of Ottawa. The noise criteria for a Class 1 area are shown on the following page:

For equipment operating continuously through the day and night, noise levels must therefore meet the requirement for the plane of a bedroom window during the night of 45 dBA, as shown in Table B2.

3.0 Noise Sources and Points of Reception

The following sections describe the characteristics of the noise sources and the nearest PORs.

3.1 Significant Noise Sources This report evaluates the noise from the 4 stationary noise sources on the proposed commercial development.

3.3 Points of Reception Points of reception have been selected by using worst case scenarios for the following types of development: permanent or seasonal residences, hotels/motels, nursing/retirement homes, rental residences, hospitals, camp grounds, and noise sensitive buildings such as schools and places of worship. We have chosen three Points of Reception (POR) for the noise level analysis. POR 1 is located at 149 Fifth Avenue approximately 40m to the north. POR 2 is located at the Free Methodist Church at 2 Monk St. approximately 50m to the West. POR3 is located at the residential units at 9-13 Monk St. approximately 30m to the South. The figure below depicts these points of reception in our 3D environmental noise model.

4.0 Methodology Used in Noise Impact Calculation The following sections describe the methodology and software used to model the sound pressure levels at the points of reception while taking into account parameters such as source levels, distance, topography, barriers and building geometry.

4.1 Procedure Used to Assess Noise Impact at Each Point of Reception This environmental noise analysis was done using an environmental noise modeling software called Cadna/A which references ISO 9613. Cadna/A predicts environmental noise through calculations based on a 3D model which uses geometrical, landscape and topography data, combined with details of the proposed construction and the noise source sound power levels. We created a 3D rendering of the proposed commercial development site and nearby PORs and placed the noise sources representing at the locations shown on the mechanical plans. Each source is represented by a blue cross as seen in figure 3.3.1. Sound power levels per octave band were entered into Cadna/A for each source and the resulting sound pressure levels were calculated at the points of reception. As a visual aid, Cadna/A can represent the resulting noise levels with a sound pressure level map, which uses a colour grid to indicate the noise levels throughout the model. Section 5 on the following page shows the results of our analysis with 3D figures displaying sound pressure level maps.

4.2 Other Parameters/Assumptions Used in Calculations The following chart describes the parameters used in the Cadna/A model:

5.0 Acoustic Assessment Summary This section summarizes the Cadna/A calculated sound pressure levels at the PORs from the noise sources with no noise mitigation.

5.1 Acoustic Assessment Summary of All Noise Sources

Figure B2 – Sound Pressure Levels (SPL) at PORs due to noise sources.

(colours will display properly when this document is printed in colour or viewed on a computer) The noise map in Figure B2 is similar to a temperature map showing hot zones and cool zones. The red/purple coloured zones are areas with noise levels at or above the by-law limit of 50 dBA and green coloured zones have levels less than 50 dBA. The legend attached to the image explains the different colour levels. The values on the buildings at POR1, POR2 and POR3 show the respective dBA levels for each of those buildings. Table B7 below summarizes the resulting sound pressure levels at these PORs.

POR1

POR1 (dBA) POR2 (dBA) POR3 (dBA) 44 50 53

Table B7 –SPLs (dBA) at PORs from the noise sources.

Using the manufacturer’s SWL data for the noise sources without any noise mitigation, the resulting SPL at POR1 is 44 dBA, 50 dBA at POR2 and 53 dBA at POR3 . The noise at both POR2 and POR3 are above the City of Ottawa’s 45dBA limit. Therefore, noise mitigation solutions must be added to some of the mechanical equipment.

5.2 Required Noise Mitigation Measures All the noise sources of the proposed development will require sound attenuation. Reducing the overall sound of the MUA and garage exhaust fans is straightforward. For the MUA, a 36inch silencer can provide enough insertion loss to render the overall SPL of the MUA insignificant at the place of the window at the PORs. We have modeled the following silencer added on to the MUA to reduce the noise it generates:

Silencer Sound Attenuation per Octave Band For Vibro-Acoustics RD-ULV F1 36 inches for MUA

Frequency (Hz) 63 125 250 500 1000 2000 4000 8000

Insertion Loss (dB) 7 14 19 18 25 23 18 16 Table B8 – Insertion Loss of the required Silencer for the MUA.

This silencer, Vibro-Acoustics RD-ULV F1 36 inches, reduces the noise from the MUA significantly. It provides enough insertion loss to prevent the MUA disturbing the surrounding environment. The garage exhaust fans must also be silenced. The following silencer insertion loss would be appropriate:

Minimum Silencer Sound Attenuation per Octave Band for garage exhaust fans

Frequency (Hz) 63 125 250 500 1000 2000 4000 8000

Insertion Loss (dB) 7 10 13 13 19 17 12 10 Table B9 – Insertion Loss of the required Silencer for the garage exhaust fans.

Reducing the sound generated by the fluid cooler is much more difficult. As it is an exterior piece of equipment, a typical silencer cannot be added to attenuate the sound pressure level it produces. The sound power level of the FC is 86 dBA. To achieve a sound pressure level of 45dBA from such a source, you need to be approximately 50m away. The nearest buildings are between 20m and 30m away. This means that the SPL of the FC at the plane of window of the surrounding buildings will be higher than 45 dBA, the noise limit of the City of Ottawa. In order to reduce the noise, there are two options:

http://www.sota.ca/



1. Choose a FC model that produces a lower sound power level 2. Erect a barrier around the FC to attenuate the sound For option 1, reducing the overall SWL by 3dB at each octave band will lower the sound produced enough to be under the bylaw limit. Since the principal source of sound from the FC is 4 meters above the the bottom of the unit, option 2 requires a 3m high barrier be built around the FC. If the FC is placed on piers, the barrier must extend to 1m below the top of the FC. This may be an undesirable solution, however unless the SWL may be reduced by a minimum the 3dB at each octave band, it is the only possibly solution to reducing the noise produced by this piece of equipment. The figure below gives an example of where this barrier could be installed.

6.0 Summary of Recommendations In order for the sound pressure level at the plane of window of each of the nearest buildings to be below the City of Ottawa Environmental Noise Control Guideline limit of 45 dBA, all sound sources on the proposed development at 852 Bank St. must have noise mitigation measures.

Silencers must be added to the MUA and garage exhaust fans. Insertion losses for the silencers can be found in section 5.2

The Fluid Cooler must have a lower sound power level of 3db at each octave band, or a 3m high barrier must be erected around it, to attenuate the sound that it produces.

Once these measures are taken, the noise created by all units on the 852 Bank St. Development will meet the noise control limit of 45dBA.
