This report has been prepared in accordance to the City of Ottawa s Environmental Noise Control Guidelines (ENCG). The City of Ottawa s ENCG states that the road and light railway noise levels inside a living space must be below 45 dba during the day and must be below 40 dba inside a bedroom at night. This report uses traffic information we have gathered from the ENCG in order to assess the noise impact to the future condo building at 1140 Wellington. This data was evaluated using the Ontario Ministry of the Environment s traffic noise software, STAMSON. From this we have determined, that based on the predicted noise levels at 1140 Wellington and the façade materials (recommended in this report), no further design changes are required to meet the City of Ottawa s ENCG requirements for indoor sound levels. The City of Ottawa s ENCG does require that: The residential units in this building require forced air heating and central air conditioning The following warning clause (type D) is required on the Agreement of Purchase and Sales: 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 City s and the Ministry of the Environment s noise criteria. We have provided three (3) hard copies of this report for your review and approval. If you have any questions or concerns please feel free to contact our firm.

4 REP Taggart 1140 Wellington Noise Control Study Page 4 of INTRODUCTION State of the Art Acoustik was commissioned by The Taggart Group to complete a noise impact study as part of a site plan assessment report for 1140 Wellington Street West in Ottawa, Ontario. This noise impact study analyses the predicted environmental noise for the proposed site and provides recommendations in order to meet the regulations set out by the City of Ottawa s Environmental Noise Control Guidelines (ENCG). This study has been completed for all major roadways within 100 meters of the building, all railways within 250 meters of the building and all freeways or provincial highways within 500 meters of the building, as required per the ENCG, section BACKGROUND INFORMATION 2.1 Project Description The proposed building is located at 1140 Wellington Street West in Ottawa, Ontario, will stand 20 meters tall, will have 2 levels of underground parking and a total of 6 stories with retail units on the ground level. The residential units will start on the 2 nd floor. The units on this level will be considered the most noise sensitive units due to their proximity to ground level traffic noise. 2.2 Site Plan On the following page (Figure 1) is a copy the site plan of the proposed building at 1140 Wellington St. West from Barry J. Hobin & Associates Architects. STATE OF THE ART ACOUSTIK INC Polytek Street Ottawa, ON K1J 9J3 E:sota@sota.ca T: F:

6 REP Taggart 1140 Wellington Noise Control Study Page 6 of NOISE IMPACT PROCEDURE 3.1 Building Faces and Representative Bedrooms The second level of 1140 Wellington Street West is the closest level to the street that has residential units. Due to it s proximity to street level, this level is the most noise prone level and so it represents the worst case for sensitivity to traffic noise. On this level, we determined and assessed the most noise sensitive unit. If this unit meets the requirements of the ENCG, then all the units in the condo building will then meet the requirements. Since corner units are the most noise prone units, we evaluated the traffic noise levels at the exterior of all four corner units. Based on the traffic noise described in Section 4, we found that unit #1 at the north-east corner had the highest level of traffic noise. This was expected since this corner is at the intersection of Wellington Street West and Rosemont Avenue. Table 3.1 below, summarizes the floor, wall and window areas of the unit s two bedrooms and living space.

7 REP Taggart 1140 Wellington Noise Control Study Page 7 of Procedure Used to Assess Noise Impacts 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 3.2 and 3.3 below are the maximum sound pressure levels for outdoor and indoor living areas taken from table 1.1 of the ENCG. Source Type Outdoor Leq Levels Class 1 Area Class 2 Area Class 3 Area Road Traffic and Light Rail (dba) Rail (heavy) Traffic (dba) Aircraft (NEF) Table 3.2 Criteria for Outdoor Sound Levels at the Outdoor Living Area Where : Class 1 refers to the major urban areas in the City of Ottawa *this applies to this report Class 2 refers to remote or smaller suburban areas in Ottawa with acoustic environment combining class 1 & 3 Class 3 refers to rural areas in the City of Ottawa having little or no road traffic where natural sounds are dominant Time Indoor Leq Levels (dba) Class 1, 2 & 3 Areas Road Traffic/Light Rail (dba) 07:00 23:00 45 for Living Quarters 23:00 07:00 40 for Bedrooms Table 3.3 Criteria for Indoor Living Area Sound Levels An Outdoor Living Area is defined by the ENCG as an outdoor protected amenity area which is 56m 2 for single family dwellings, 46 m 2 for semi-detached units and 37 m 2 for row housing. These amenities can be backyards, terraces and patios. Balconies may be considered an Outdoor Living Area for the occupant assuming: they are the only outdoor living area for the occupant, the depth is a minimum of 4 meters, and they are outside the exterior building façade and are unenclosed An Indoor Area is defined by the City of Ottawa s ENCG as a Living/dining areas of residences, hospitals, schools, nursing/retirement homes, day-care centers, theatres, places of worship, libraries, individual or semi-private offices, conference rooms, reading rooms, etc. The ENCG states that noise assessments are to be prepared when the living 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 Light Rail Transit system corridor noise and 75m for its ground-bourne vibration assessment STATE OF THE ART ACOUSTIK INC Polytek Street Ottawa, ON K1J 9J3 E:sota@sota.ca T: F:

8 REP Taggart 1140 Wellington Noise Control Study Page 8 of Noise Attenuation Requirements This section outlines the required 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 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.

9 REP Taggart 1140 Wellington Noise Control Study Page 9 of 18 Table 3.5, summarizes the warning clauses referred to above in table 3.4 (from ENCG Table 1.13). TYPE Type A Type B Type C Type D Type E WARNING CLAUSE 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 City s and the Ministry of the Environment s noise criteria. 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 City s and the Ministry of the Environment s noise criteria. This dwelling unit has been fitted with a forced air heating system and the ducting, etc. was sized to accommodate central air conditioning. Installation of central air conditioning by the occupant will allow windows and exterior doors to remain closed, thereby ensuring that the indoor sound levels are within the City s and the Ministry of the Environment s noise criteria. (Note: The location and installation of the outdoor air conditioning device should be done so as to comply with noise criteria of MOE Publication NPC-216, Residential Air Conditioning Devices and thus minimize the noise impacts both on and in the immediate vicinity of the subject property. 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 City s and the Ministry of the Environment s noise criteria. 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 Warning Clause Statements from the City of Ottawa. In summary, a forced air heating system with provision for a central air conditioning system is required if the daytime noise levels are between 55 and 65 dba and/or the night time noise levels are between 50 and 60 dba. The criteria shall be modified to require installation of a central air conditioning system when the daytime noise level exceeds 65 dba and/or the night time noise level exceeds 60 dba; furthermore, the exterior building components must be analyzed to ensure the indoor sound level targets are achieved. This includes analysis of the exterior wall, door, window and/or glazing system specifications as appropriate. The Warning Clauses are to be placed on the title and included in both the Development Agreement and within the Offer of Purchase and Sale. The appropriate clause is selected and put in the conclusions section of this report. STATE OF THE ART ACOUSTIK INC Polytek Street Ottawa, ON K1J 9J3 E:sota@sota.ca T: F:

10 REP Taggart 1140 Wellington Noise Control Study Page 10 of 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 (AIF 1 ) 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 : maximum daytime indoor Leq for living spaces should be 45 dba maximum nightime indoor Leq for bedrooms should be 40 dba The following equation is from Acoustic Insulation Factor: A Rating for the Insulation of Buildings against Outdoor Noise, section IV part 2 written by J.D. Quirt revised in June 1980 : Required AIF = Outside Leq - Indoor Leq (Req) + 10 log 10 (Number of Components) + 2dB The required AIF is based on the Outside Leq, Indoor Leq required and the total number of exterior façade components. J.D. Quirt of the National Research Council states 1 : 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 1 J.D.

11 REP Taggart 1140 Wellington Noise Control Study Page 11 of Noise Sources and Analysis The following sections describe the characteristics of the noise sources. 4.1 Road and Railway Traffic Information For this study, the major noise sources considered are roads. The major roadways considered are: 1) Wellington Street (arterial road less than 100m from building) 2) Rosemount Avenue (arterial road less than 100m from building) - continues onto Caruthers Ave, both Rosemount & Caruthers were treated as one street simply referred to as Rosemont Avenue 3) Sherbrooke Avenue (arterial road less than 100m from building) - continues onto Stirling Ave, both Sherbrooke & Stirling will be treated as one street simply referred to as Sherbrooke Avenue 4) Queensway (400 series provincial highway less than 500m from building) highway 417 Table 4.1 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.

Building Façade Sound Pressure Levels Leq (dba) at Building Face Day Night Northeast Southeast Northwest Southwest Table 4.4 Predicted Road and Railway Noise Level (Leq) Summary for Daytime The table above shows that the noise pressure levels at the building face range from 67.6 to 71 dba during the day and from 60 to 63.3 dba during the night. According to the ENCG, since the levels exceed 65dBA during the day and 60 at night, the exterior building components must be analyzed to ensure the indoor sound level targets are achieved. This will be done in the next section. As the Northeast corner has the highest noise level, ensuring that exterior building components achieve the appropriate Acoustic Insulation Factor at this corner will guarantee that all other facades meet noise control guidelines.

16 REP Taggart 1140 Wellington Noise Control Study Page 16 of Exterior Building Component Analysis In this section, we determine if the building complies with the City of Ottawa s ENCG indoor noise requirements based on the currently selected wall and window construction. We compare the estimated minimum façade AIF to the estimated AIF of the currently selected façade materials. 5.1 Initial Minimum AIF Calculations Using the equation outlined in section 3.4 of this report, we have calculated the Minimum AIFs of the building façade at the northeast corner of the 2 nd level for both day time (bordering a living space) and night time (bordering a bedroom). The façade is made up of the two or three components as described in Table These AIFS are summarized in Table 5.1 below. Minimum Acoustic Insulation Factor (AIF) Building Façade Location 2 nd level Living Space (Day 2 nd level Bedroom North East Corner N 71dBA) (Night-63dBA) Master Bedroom (MBR) nd Bedroom (2BR) Living Space (LS) Table 5.1 Minimum AIF Values Summary (with N component façade) 5.2 Intial Exterior Wall AIF Calculations The AIFs of the components in the façades of the selected rooms (materials and areas listed in Section 4.3) have been estimated using the Canadian Mortgage and Housing Corporation (CMHC), Road and Rail Noise: Effects on Housing (Tables 6.2 and 6.3). The estimated AIFs for the exterior wall compents for the three rooms have been estimated and summarized below in Table 5.2. The exterior wall components meets the minimum AIF of 33.

17 REP Taggart 1140 Wellington Noise Control Study Page 17 of Adjusted Minimum AIF Calulation If any exterior wall component s AIF is 10 AIF points above the minimum AIF (in this case 33), then the minimum AIF may be decreased since it can be based on less components as specified in Section 3.4. Since the EW5 component has an AIF of 54 and the EW2 component has an AIF of 43 in each case in Table 5.2, the number of components can be reduced to 1. We have recalculated the required minimum AIF for the façade with the reduced number of components and have summarized it in Table 5.3 below. Building Façade Location North East Corner N Minimum Acoustic Insulation Factor (AIF) 2 nd level Living 2 nd level Bedroom Space (Day (Night-63dBA) 71dBA) Master Bedroom (MBR) nd Bedroom (2BR) Living Space (LS) Table 5.3 Minimum Adjusted AIF Values Summary (with 1 component façade) 5.4 Final Exterior Window AIF Calculations The daytime minimum AIF of 28 dictates the overall window construction. If this minimum AIF is met, the night time minimum AIF will be met. In order for 1140 Wellington Street West, to meet the City of Ottawa Environmental Noise Control Guidelines, the chosen façade window materials must meet the AIF requirement for room most heavily impacted by noise. This would be the living space (LS) at the north-east corner. Table 5.3 specifies the types of double glazing with a minimum AIF of 28 suitable for a space with 73% window area to floor area, as given in Canadian Mortgage and Housing Corporation, Road and Rail Noise: Effects on Housing Table 6.2. Glass Thickness Interplane Spacing 2mm & 2mm 35mm 3mm & 3mm 25mm 4mm & 4mm 20mm 3mm & 6mm 16mm 6mm & 6mm 16mm Table 5.3 Double Glazing with AIF >28 for 73% Window Area to Floor Area If one of the above glazing types is chosen, then the most noise sensitive room on the most noise sensitive floor meets the minimum specified AIF criteria. It can be extrapolated that all rooms at 1140 Wellington St. will meet the minimum required AIF to meet the City of Ottawa Noise Control Guidelines.

18 REP Taggart 1140 Wellington Noise Control Study Page 18 of Required Warning Clauses The exterior noise at the plane of the window was determined to be 71 dba during the day and 63 dba during the night. As per Section 3 of this report, a warning type D must be incorporated into the development agreement and/or the Agreement of Purchase and Sale. 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 City s and the Ministry of the Environment s noise criteria. 6.0 Conclusion As long as the exterior façade of 1140 Wellington Street West is composed of double glazed glass as per table5.3 (or better), there will be sufficient sound isolation to meet the City of Ottawa Environmental Noise Control Guidelines. Due to the level of noise at the plane of the window during the day and night, the City of Ottawa ENCG stipulates that: The residential units in this building require forced air heating and central air conditioning A warning clause Type D is required on the Agreement of Purchase and Sales. No other mitigation measures are required. Should you have any questions regarding this report, please do not hesitate to contact us. Prepared by: Reviewed by: Eric Sladic B.Sc., B.Eng.
