2 Global Centre for Pluralism Page 2 of 11 Environmental Noise Study 14 March 2014 Executive Summary KPMB Architects and Imara Sussex Drive Limited have retained the services of Aercoustics Engineering Limited to prepare an Environmental Noise Study for the proposed office use at the Global Centre for Pluralism, located at 330 Sussex Drive, Ottawa, Ontario in support of the rezoning application to permit office use as an additional permitted use at this location. The Global Centre for Pluralism will see the rehabilitation of the former Canadian War Museum and Dominion Archives building which is a 3-storey institutional building, directly adjacent to the National Art Gallery to the south and the Royal Canadian Mint directly north. The purpose of this study is to examine the future noise impact on the office use within the building from the future road traffic on the Alexandra Bridge, Sussex Drive, Macdonald Cartier bridge and industrial noise from the Royal Canadian Mint in order to meet the noise guidelines of the Ontario Ministry of the Environment (MOE) and to satisfy the requirement of the City of Ottawa. The impact of road traffic has been predicted using the city of Ottawa ultimate traffic forecasts, while the impact from the Royal Canadian Mint is based on Aercoustics noise measurements taken 27 October An inspection of the GCP windows indicates that the operable window seals and operable window closure mechanism should be upgraded. Predicted indoor noise from ultimate road traffic and Royal Canadian Mint noise is within the City of Ottawa noise guidelines for office use. Predicted outdoor noise at the middle of the GCP forecourt, from ultimate road traffic and Royal Canadian Mint noise is significantly above desirable levels therefore a public address system or landscaped barrier should be considered if Sussex Drive reaches its ultimate traffic forecast. Predicted outdoor noise at the west side windows will be within acceptable noise limits. With the incorporation of noise controls recommended in this report, the indoor sound levels of the proposed Global Centre for Pluralism will comply with the noise guidelines of the MOE and the City of Ottawa. aercoustics.com

4 Global Centre for Pluralism Page 4 of 11 Environmental Noise Study 14 March Introduction Aercoustics Engineering Limited has been retained by KPMB Architects to prepare an Environmental Noise Study for the proposed Global Centre for Pluralism, rehabilitation and fit-out project, located at 330 Sussex Drive, Ottawa, Ontario in support of the rezoning application. The building that formerly was the Canadian War Museum is to be renovated and used by the Global Centre for Pluralism, which is already permitted as a Community Centre use under the current zoning. The rezoning application is to allow Office as an additional permitted use. The purpose of this study is to examine the future noise impact on the building from the future road traffic on the Alexandra Bridge, Sussex Drive, Macdonald Cartier bridge and industrial noise from the Royal Canadian Mint in order to meet the noise guidelines of the Ontario Ministry of the Environment (MOE) and to satisfy the requirements of the City of Ottawa for the rezoning application. The National Art Gallery is located directly south. The Royal Canadian Mint is located directly north. Institutional buildings are located east of Sussex Drive. The report is based on the Architectural plans prepared KPMB Architects dated 28 October 2013, and a site visit by Aercoustics of 27, 28 October A key plan showing the site location is given in Figure 1 and a site plan showing the building layout is illustrated in Figure 2. The building will include offices, meeting rooms, libraries, dialogue centre (performance space), and tenant space. The site will also include a landscaped forecourt. aercoustics.com

5 Global Centre for Pluralism Page 5 of 11 Environmental Noise Study 14 March Guidelines and Criteria 2.1 Noise Requirements The proposed office use is considered a noise sensitive land use by the City of Ottawa and therefore the proponent has requested noise analysis of their exterior spaces. Table 1: Road Traffic Noise Criteria Type of Space General offices, reception areas, retail stores, etc. (Time period: 16 hr, hrs) Living/dining areas of residences, hospitals, schools, nursing/retirement homes, day-care centres, theatres, places of worship, libraries, individual or semi-private offices, conference rooms, reading rooms, etc. (Time period: 16 hr, 07:00-23:00) Sleeping quarters of hotels/motels (Time period: 8hr, hrs) Sleeping quarters of residences, hospitals, nursing/retirement homes, etc. (Time period: 8hr, hrs) Outdoor living area (Time period: 16 hr, 07:00-23:00) Road Traffic Equivalent Sound Level (Leq), dba Noise Measurements Noise measurements of the existing background sound levels were taken on 27 & 28 October Indoor and outdoor noise measurements were taken with a type 1, integrating sound level meter. Noise measurements were taken at a location adjacent to Lady Grey Drive to assess the distinct drone character of the Alexandra Bridge due to its open steel grid roadway deck. After comparing the measured bridge noise versus the predicted bridge noise, a correction factor of 10 dba was applied in our traffic noise prediction analysis to account for the significantly higher noise of the Alexandra Bridge compared to a typical bridge with paved surface. Vehicle counts were also taken during our road traffic noise measurements in order to calibrate the noise prediction models. Predicted road noise from Alexandra Bridge using MOE s Stamson program, assuming standard pavement, is 10 dba below the measured noise level, therefore predicted noise from the Alexandra Bridge has been adjusted by +10 dba. aercoustics.com

7 Global Centre for Pluralism Page 7 of 11 Environmental Noise Study 14 March Description of Stationary Noise Sources The Royal Canadian Mint is located directly north of the GCP. Royal Canadian Mint trucks make use of the GCP driveway to deliver materials to their west side rear and to their south delivery door. The Royal Canadian Mint operates 24 hours, 7 days a week. There are four Royal Canadian Mint roof top blower fans and their associated exhaust stacks nearest the GCP that operate continuously 24/7.Ocasionaly there are gas tank blow-off noise events and deliver truck arrivals. The National Art Gallery is located directly south, but does not contain any significant steady state noise sources that will impact the GCP. The Global Centre for Pluralism has an outdoor cooling tower on its southwest corner, but this could not be measured, therefore its noise impact is unknown at this time. 4 Noise Predictions 4.1 Road Traffic Data The City Ottawa and MOE requires that road traffic noise predictions be conducted in accordance with Reference 1, and be based on traffic data from Table 1.7 of the City of Ottawa Environmental Noise Guideline. 4.2 Road Noise Calculation Procedure Noise level calculations were performed in accordance with the Ministry of Environment Guidelines outlined in Reference 1 and by the Guidelines of the Ontario Road Noise Analysis Method for Environment and Transportation (ORNAMENT). Sample traffic noise prediction printouts from MOE's Road & Rail Traffic Prediction Model Stamson Version 5.02 are included in Appendix. The equivalent sound levels (Leq) due to road noise have been calculated at representative worst case receptor locations adjacent to Sussex Drive and on the west side nearest the Alexandra Bridge. Noise has been predicted during the daytime 0700 to 2300 outside the plane of a worst case window. Predicted road noise from Alexandra Bridge using MOE s Stamson program, assuming standard pavement, is 10 dba below the measured noise level, therefore predicted noise from the Alexandra Bridge has been adjusted by +10 dba. aercoustics.com

8 Global Centre for Pluralism Page 8 of 11 Environmental Noise Study 14 March 2014 Table 3: Road Traffic Data Sussex Drive Alexandra Bridge Macdonald Cartier Bridge Year Ultimate Ultimate Ultimate AADT 35,000 15,000 50,000 Day/Night 92/8 92/8 92/8 Split No. of Lanes % Medium Day/ 7% 7% 7% Trucks Night % Heavy Trucks Day/ Night 5% 5% 5% Posted Speed:km/hr Grade <2% <2% <2% The noise impact assessment has considered two scenarios: The first scenario assessed locates the GCP in the west wing. This is the worst case scenario because indoor noise impact is greatest on the west wing due to high noise levels from the Royal Canadian Mint and the Alexandra Bridge. 4.3 Indoor Noise Indoor noise has been predicted using the NRC s IBANA computer program. This computer program is capable of calculating the indoor noise from any given outdoor environmental noise source. The GCP site is impacted by three uniquely different environmental noise sources which include the Alexandra Bridge, Sussex Drive and industrial noise from the Royal Canadian Mint. Each of these noise sources has a unique frequency spectrum which IBANA allows as a custom noise input. Sussex Drive is considered standard mixed traffic; therefore the MOE frequency spectrum is used as an input. The Alexandra Bridge and Mint frequency spectrum is based on Aercoustics measured spectrum of October The acoustical performance of building components is input to the computer program in the form of 1/3 octave transmission loss data that is provided by NRC and by acoustically accredited labs and by Aercoustics file data for custom building components which are not readily available. aercoustics.com

9 Global Centre for Pluralism Page 9 of 11 Environmental Noise Study 14 March Total Noise Impact Table 4 below presents the combined noise impact from ultimate forecasted road traffic and from Royal Canadian Mint stationary noise sources as predicted at the worst case locations of the GCP with GCP windows closed. Table 4: Predicted Environmental Noise Impact Point of Reception Road Traffic Forecast Predicted Total Daytime Noise (dba) (1) Sound Level Limit (dba) (2) Environmental Noise Impact (dba) (1)-(2) Indoors: 3 rd floor, Wing A Ultimate Indoors: Wing A, NW corner, floor plan Ultimate Indoors: 3 rd floor, Wing B Ultimate < Outdoors: 3 rd floor, west face, Wing A Ultimate Outdoors: GCP forecourt Ultimate Outdoors: GCP forecourt Existing Conclusion The predicted environmental indoor noise levels for the office use within the Global Centre for Pluralism with windows closed are below the City of Ottawa noise criteria; therefore no further environmental noise studies are contemplated. The City of Ottawa does not have sound level criteria for outdoor living spaces for institutional/commercial sites, but the proponent has requested a noise assessment since the proposed outdoor spaces could be used for outdoor events/performances or future landscaping. Exterior noise outside the windows of the 3 rd floor is likely to be acceptable. Noise at the GCP forecourt is significantly above the 55 dba sound level target if Sussex Drive reaches ultimate traffic forecast levels. This noise exceedance at the forecourt could interfere with speech intelligibility at normal voice levels, therefore a landscaped noise barrier or amplified sound system should be considered. aercoustics.com

10 Global Centre for Pluralism Page 10 of 11 Environmental Noise Study 14 March Summary of Recommended Noise Controls 1. GCP operable window seals and operable window closure mechanism should be upgraded to eliminate noise leaks 2. A public address system or landscaped noise barrier on the east side of the GCP forecourt should be considered if Sussex Drive reaches its ultimate traffic forecast. 6 References 1.
