Noise Feasibility Study, Proposed Mixed-Use/Residential Development Page 1 47 – 75 Willow Road, Guelph, Ontario November 29, 2019

1 Introduction and Summary

HGC Engineering was retained by Black, Shoemaker, Robinson & Donaldson Limited to conduct a

noise feasibility study for a proposed mixed-use/residential development to be located at 47 – 75

Willow Road in the City of Guelph, Ontario. The proposed development will consist of two 6-storey

mixed-use/residential buildings with commercial uses on the ground floor and one level of

underground parking. The study is required by the Municipality as part of their rezoning and

approvals process.

The primary sources of transportation noise are road traffic on Willow Road and Dawson Road.

Relevant road traffic data was obtained from City of Guelph personnel. The data was used to predict

future traffic sound levels at the façades of the proposed buildings and in the outdoor amenity area.

The predicted sound levels were compared to the guidelines of the Ministry of the Environment,

Conservation and Parks (MECP) and the City.

The results of this study indicate that with suitable noise control measures integrated into the design

of the buildings, it is feasible to achieve the indoor MECP guideline sound levels from road traffic

sources. The recommended noise control measures include appropriate wall and window glazing

assemblies, and an alternative means of ventilation to open windows. Warning clauses will need to

be included in the property, tenancy and purchase and sale and/or rental agreements to warn

occupants of potentially audible transportation noise levels and of the nearby commercial uses.

An analysis was also conducted to determine the potential impact of noise from rooftop units on the

adjacent commercial building located at the west side of the site on the proposed residential units in

addition to the potential impact of mechanical equipment associated with the proposed buildings on

existing residential apartment units. Detailed information regarding the type or model of the

proposed mechanical equipment was not known at the time of the study, but reasonable estimates of

the sizes and tonnages have been used based on experience with similar projects. Manufacturer’s

sound power data was used to estimate sound levels associated with the proposed building on

existing dwelling units. Specifications and sound data for the existing rooftop units of the existing

commercial building were provided by the developer and used to estimate the impact of sound levels

associated with the existing building on proposed residences.


The results indicate that the sound emissions from the rooftop equipment associated with the existing

commercial building on the proposed residential buildings, as well as the sound emissions

mechanical equipment associated with the proposed buildings on existing residential receptors in the

area will be within MECP sound level criteria without additional mitigation. Physical mitigation

measures are not required for mechanical equipment associated with the existing and proposed

buildings.

2 Site Description and Sources of Sound

Figure 1 shows a key plan which identifies the location of the proposed residential development at

the northwest corner of Dawson Road and Willow Road, specifically at 47 – 75 Willow Road in the

City of Guelph, Ontario. The site plan dated October 2, 2019 is included as Figure 2. The proposed

development will consist of two 6-storey mixed-use/residential buildings. The proposed buildings

will have commercial uses on the ground floor and one level of underground parking.

A site visit was conducted by HGC Engineering personnel in September 2019 to make observations

of the acoustic environment and to identify the significant noise sources in the vicinity. During the

site visit, it was noted that the primary sources of sound impacting the site are vehicular traffic on

Willow Road and Dawson Road. Highway 6 is located approximately 900 m away from the closest

proposed building façade and therefore has not been included in the analysis.

There are existing residential uses in the surrounding area. The site is currently occupied by a large

commercial building. With the exception of the western portion of the existing building, the

remaining structure will be demolished to make way for the proposed development. There is

mechanical equipment on the roof of the existing commercial building and these have been included

in the noise assessment. The area of the site is classified as a Class 1 area since the background

sound level is dominated by the activities of people and road traffic.

2.1 Road Traffic Noise Criteria

Guidelines for acceptable levels of road traffic noise impacting residential developments are given in

the MECP publication NPC-300 “Environment Noise Guideline Stationary and Transportation

sources – Approval and Planning”, release date October 21, 2013, and are listed in Table I below.

The City of Guelph Noise Control Guidelines version 1.0 effective January 1, 2019 were also used in


conjunction with NPC-300. The values in Table I are energy equivalent (average) sound levels [LEQ]

in units of A-weighted decibels [dBA].

Table I: Road Noise Criteria (dBA)

Daytime LEQ(16 hour)

Road Nighttime LEQ(8 hour)

Road

Outdoor Living Areas 55 dBA -- Inside Living/Dining Rooms 45 dBA 40 dBA

Inside Bedrooms 45 dBA 40 dBA

Daytime refers to the period between 07:00 and 23:00, while nighttime refers to the period between

23:00 and 07:00. The term "Outdoor Living Area" (OLA) is a noise sensitive space intended for the

quiet enjoyment of the outdoor environment and is readily accessible from the building. OLA’s

include backyard and side yard areas of single family, semi-detached and townhouse dwellings,

gardens, terraces and patios, balconies and elevated terraces (e.g. Rooftops) that are not enclosed

with a minimum depth of 4 meters and common outdoor areas associated with high-rise and other

multi-unit buildings and passive recreational areas such as parks if identified by the City. Front yards

areas are not OLA’s.

The target sound level in an OLA is 55 dBA. The guidelines in the MECP publication allow the

sound level in an Outdoor Living Area to be exceeded by up to 5 dBA, without mitigation, if

warning clauses are placed in the purchase and rental agreements to the property. Where OLA sound

levels exceed 60 dBA, physical mitigation is required to reduce the OLA sound level to 55 dBA.

Where mitigation is not technically, economically and administratively feasible, an excess above the

limit of 55 dBA is acceptable with the use of a noise warning clause with some justification.

A central air conditioning system as an alternative means of ventilation to open windows is required

for dwellings where nighttime sound levels outside bedroom or living/dining room windows exceed

60 dBA or daytime sound levels outside bedroom or living/dining room windows exceed 65 dBA.

Forced-air ventilation with ducts sized to accommodate the future installation of air conditioning is

required when nighttime sound levels at bedroom or living/dining room windows are in the range of

51 to 60 dBA or when daytime sound levels at bedroom or living/dining room windows are in the

range of 56 to 65 dBA.


Building components such as walls, windows and doors must be designed to achieve indoor sound

level criteria when the plane of window nighttime sound level is greater than 60 dBA or the daytime

sound level is greater than 65 dBA due to road traffic noise.

Warning clauses are required to notify future residents of possible sound level excesses when

nighttime sound levels exceed 50 dBA at the plane of the bedroom window and/or daytime sound

levels exceed 55 dBA in the outdoor living area and at the plane of the bedroom or living/dining

room window due to road traffic.

3 Traffic Noise Predictions

3.1 Road Traffic Data

Road traffic data for Willow Road and Dawson Road was obtained from the City of Guelph in the

form of turning movement counts from 2013 and is provided in Appendix A. The data was projected

to the year 2030 using a conservative estimate of 2.5% growth per year. A commercial vehicle

percentage of 1.2% medium trucks and 0.8% heavy trucks was applied for Willow Road. A

commercial vehicle percentage of 1.2% medium trucks and 0.8% heavy trucks was applied for

Dawson Road.

A posted speed limit of 50 km/h and a day-night split of 90%/10% was used for all roadways, as per

ORNAMENT (Ontario Road Noise Analysis Method for Environment and Transportation), a

document describing modelling procedures for the prediction of road traffic noise prepared by the

MECP, for municipal roadways. Table II below indicates the road traffic data used in the analysis.

Road traffic information is included in Appendix A.

3.2 Road Traffic Noise Predictions

To assess the levels of road traffic noise which will impact the site in the future, predictions were

made using STAMSON version 5.04, a computer algorithm developed by the MECP. Sample

STAMSON output is included in Appendix B.

The predictions were performed at the top storey of the proposed buildings during daytime and

nighttime hours to investigate ventilation requirements and in the outdoor amenity area to determine

acoustic barrier requirements. The upper storeys typically represent a worst case location in terms of

traffic noise as they are potentially exposed to more of the roadway being less shielded by adjacent

structures and there is no surplus attenuation due to ground effects. The distance setbacks of the

proposed buildings from the roads indicated on the site plan and aerial photos were used in the

analysis. Reflective ground has been applied in the STAMSON calculations for A to I. The results

of these predictions are summarized in Table III. The acoustic requirements may be subject to

modifications if the site plan is changed significantly.

4 Recommendations

The predictions indicate that road traffic sound levels will exceed MECP limits at both proposed

buildings in the development. Recommendations are provided in the following sections.

4.1 Outdoor Living Areas

The predicted daytime sound level in the common amenity area located at the northwest corner of the

subject site (Prediction Location [I]) will be 58 dBA, 3 dBA in excess of the MECP’s limit. The 3

dBA sound level excess is within the discretionary range acceptable to the MECP and the City with

the use of a noise warning clause. Physical mitigation would typically not be required.

The residential units may have balconies less than 4 m in depth. These balconies are not considered

as outdoor living areas under MECP guidelines, and therefore are exempt from traffic noise

assessment.

4.2 Indoor Living Areas and Ventilation Requirements

Central Air Conditioning

The predicted sound levels at some of the façades of Building 1 with exposure to Dawson Road and

Willow Road will be greater than 60 dBA during the nighttime and 65 dBA during the daytime. To

address these excesses, the MECP guidelines recommend that the proposed buildings be equipped

with central air conditioning systems.

Provision of Central Air Conditioning

The predicted sound levels at some of the façades of Building 2 with exposure to Dawson Road and

Willow Road will be between 51 dBA and 60 dBA and/or between 55 dBA and 65 dBA during the

daytime. To address these excesses, the MECP guidelines recommend that the building be equipped

with forced air ventilation systems with ducts sized to accommodate the future installation of air

conditioning by the occupant. The use of central air conditioning will exceed this requirement.

Typical window or through-the-wall air conditioning units are not recommended for any residential

units because of the noise they produce and because the units penetrate through the exterior wall

which degrades the overall noise insulating properties of the envelope. Acceptable air conditioning

systems for individual dwelling units are those that are housed in their own closet with an access


door for maintenance. The location, installation and sound ratings of the outdoor air conditioning

devices should minimize noise impacts and comply with criteria of MECP publication NPC-300, as

applicable.

4.3 Building Façade Constructions

Future traffic sound levels at some of the façades of Building 1 (Prediction Locations [A] and [B])

with exposure to Willow Road will exceed 65 dBA during the daytime due to road traffic. MECP

guidelines recommend that the windows, walls and doors be designed so that the indoor sound levels

comply with MECP noise criteria.

Calculations have been performed to determine the building envelope constructions likely to be

required to maintain indoor sound levels within MECP guidelines. The calculation methods were

developed by the National Research Council (NRC). They are based on the predicted future sound

levels at the building facades and the anticipated area of the facade components (walls, windows and

doors) relative to the floor area of the adjacent room.

The minimum necessary specification for the building envelope is Acoustical Insulation Factor,

AIF-26 for living/dining rooms at the south and east façades of Building 1 (Prediction Locations [A]

and [B]), based on the possibility of sound entering the dwellings through the walls and windows.

Any well sealed thermopane unit have a Sound Transmission Class (STC) rating of 30, that is two 3

mm panes and a 13 mm inter-pane gap will provide sufficient noise insulation as long as the window

to floor area ratio is less than 63% for living/dining rooms. Any building construction meeting the

minimum requirements of the Ontario Building Code (OBC) will provide sufficient acoustical

insulation for the bedrooms.

The remaining façades will have predicted sound levels less than 65 dBA during the nighttime and

less than 60 dBA during daytime. Thus, any exterior wall and double glazed window construction

meeting the minimum requirements of the OBC will provide adequate sound insulation.

Further Analysis

When detailed floor plans and elevations are available for the proposed building, the glazing

requirements should be verified based on actual window to floor area ratios. If patio doors are to be

used in the dwellings, they must be included in the window area.


4.4 Warning Clauses

The MECP guidelines recommend that warning clauses be included in the property and tenancy

agreements and offers of purchase and sale for all units with anticipated road traffic sound levels

excesses. Examples are provided below.

The suggested wording for proposed dwellings with sound level excesses is given below.

Type A: 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 occasionally interfere with some activities of the dwelling occupants as the sound levels exceed the noise criteria of the Municipality and the Ministry of the Environment, Conservation and Parks.

Suitable wording for future dwellings requiring forced air ventilation systems is given below.

Type B: 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 will allow windows and exterior doors to remain closed, thereby ensuring that the indoor sound levels are within the criteria of the Municipality and the Ministry of the Environment, Conservation and Parks. (Note: The location and installation of the outdoor air conditioning device should be done so as to minimize the noise impacts and comply with criteria of MECP publication NPC-300 as applicable.)

The suggested wording for proposed dwellings requiring central air conditioning systems is given

below.

Type C: 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 Municipality’s and the Ministry of the Environment, Conservation and Parks’ noise criteria.

The suggested wording for proposed dwellings in close proximity to existing commercial facilities is

given below.

Type D: Purchasers are advised that due to the proximity of an existing commercial facility, sound levels from the facilities may be at times be audible.

These sample clauses are provided by the MECP as examples and can be modified by the

Municipality as required.


5 Stationary Noise Assessment

5.1 Criteria Governing Stationary (Industrial) Noise Sources

An industrial or commercial facility is classified in MECP guidelines as a stationary source of sound

(as compared to sources such as traffic or construction, for example) for noise assessment purposes.

The existing rooftop mechanical equipment on the roof of the commercial building located to the

west of the site can be classified as stationary sources of sound. Also, the proposed building may be

serviced by roof mounted make up air units which are also classified as stationary sources of sound.

The stationary noise source locations and receptor locations (R1 to R7) are shown in Figure 3.

The Ministry of the Environment, Conservation and Parks (MECP) provides guidelines for the

assessment of stationary noise sources. NPC-300 “Environment Noise Guideline Stationary and

Transportation sources – Approval and Planning” referenced with regard to traffic noise is also

intended for use in the planning of noise sensitive land uses adjacent to residential buildings.

The criteria is based on the background sound level at sensitive points of reception (which are

typically residences) in the quietest hour that the source can be in operation. Background sound

includes sound from road traffic and natural sounds, but excludes the sources under assessment. For

relatively quiet areas where background sound may fall to low levels during some hours, NPC-300

stipulates various minimum limits. As per NPC-300, this area is considered a Class 1 area since the

background sound level is dominated by the activities of people and road traffic. In class 1 areas,

these limits are 50 dBA for daytime periods (07:00 to 23:00) and 45 dBA at night (23:00 to 07:00).

Sources sound levels for typical rooftop mechanical units and assumed operational information

(outlined below) were used as input to a predictive computer model (Cadna-A version 2019 MR2 (32

bit) : build 173.4905), in order to estimate the sound levels from the existing commercial building at

the proposed development and the sound levels from the proposed building on existing sensitive

receptors. The computer model is based on the methods from ISO Standard 9613-2.2, “Acoustic –

Attenuation of Sound During Propagation Outdoors”, which accounts for reduction in sound level

with distance due to geometrical spreading, air absorption, ground attenuation and acoustical

shielding by intervening structures. Worst case assumptions regarding the operating duty cycles of

the equipment (100% during the daytime, and 50% during the night-time) were included based on

our experience with other projects.


5.2 Sound Level Criteria at the Residential Receptors

Typical ambient sound levels can be determined through prediction of road traffic volumes in areas

where traffic sound is dominant. Where it can be demonstrated that the hourly ambient sound levels

are greater than the exclusionary minimum limits listed above, the criterion becomes the lowest

predicted one-hour LEQ sound level during each respective period.

Using the existing traffic volumes from 2013 provided by the City, the traffic data was applied to a

generic 24 hour traffic pattern developed by the US Department of Transportation, Federal Highways

Administration contained in the report titled “Summary of National and Regional Travel Trends

1970 – 1995” dated May 1996. The traffic volumes were then used to predict sound levels at the

building facades during the day/nighttime hours to determine the minimum hourly background sound

levels at those locations due to the traffic on the public roadways.

The sound level predictions and the recommended criteria during the daytime and nighttime at the

existing and proposed receptors are shown in Tables IV and V. To assess the levels of background

road traffic noise, noise predictions were made using a numerical computer modelling package

(Cadna/A version 2019 MR2 (32 bit) build: 173.4905). The model is based on the methods from ISO

Standard 9613-2.2, “Acoustics – Attenuation of Sound During Propagation Outdoors”, which

account for reduction in sound level with distance due to geometrical spreading, air absorption

attenuation and acoustical shielding by intervening structures.

Compliance with MECP criteria generally results in acceptable levels of sound at sensitive receptors

although there may be residual audibility during periods of low background sound.

5.3 Assessment of Noise Emissions from Existing Rooftop

Mechanical Equipment at Adjacent Sensitive Receptors

Information regarding the specifications and sound power levels of the existing rooftop mechanical

equipment at the commercial building located at the west of the subject site were provided and

included in Appendix C. The sound levels due to the existing rooftop mechanical equipment at the

existing commercial building are summarized in the following table and shown graphically in

Figures 4 and 5.

Table VI: Predicted Sound Levels from the Existing Noise Sources at the Proposed Residences [dBA]

South Façade 59/52 37 34 East Façade 63/58 <35 <30 North Façade 59/52 <35 <30 West Façade 50/45 39 36


It is concluded that sounds from the existing rooftop mechanical equipment associated with the

adjacent commercial building are anticipated to be below background sound levels at the proposed

buildings and physical mitigation is not required.

5.4 Assessment of Stationary Noise Sources Associated with the

Proposed Development at Existing Sensitive Receptors

Sound power levels for rooftop makeup air units and the air conditioning systems for individual

dwelling units were estimated based upon manufacturer’s data for similar mechanical equipment

used in similar past projects, since the details of the equipment were not known at the time of this

report. Two make-up air units on the rooftop of the building with sound power ratings of 90 dBA

were assumed in the analysis. The individual unit air conditioning systems were assumed to have a

sound power level of 66 dBA. Proposed noise source locations are shown in Figure 3. The sound

levels created by this equipment at the closest neighbouring residences are summarized in the

following table and shown graphically in Figures 6 and 7.

Table VII: Predicted Sound Levels from the Proposed Building at the Existing Residences [dBA]

Receptor Criteria

(Day/Night) Day Night

R1 (existing 2.5-storey residence) 60/54 43 39 R2 (existing 2.5-storey residence) 60/54 42 38 R3 (existing 2.5-storey residence) 61/54 43 39 R4 (existing 2.5-storey residence) 61/55 42 39 R5 (existing apartment building) 58/51 45 41 R6 (existing apartment building) 61/55 48 43 R7 (existing apartment building) 61/55 50 46 R8 (existing apartment building) 58/52 50 45

These predicted sound levels at the existing residences are less than background sound levels, based

on this typical worst-case operating scenario. Noise mitigation measures are not required.


6 Impact of the Development on Itself

Section 5.9.1 of the Ontario Building Code (OBC) specifies the minimum required sound insulation

characteristics for demising partitions, in terms of Sound Transmission Class (STC) values. In order

to maintain adequate acoustical privacy between separate suites in a multi-tenant building, inter-suite

walls must meet or exceed STC-50. Walls separating a suite from a noisy space such as a refuse

chute, or elevator shaft, must meet or exceed STC-55. In addition, it is recommended that the

floor/ceiling constructions separating suites from any amenity or commercial spaces also meet or

exceed STC-55. Tables 1 and 2 in Section SB-3 of the Supplementary Guideline to the OBC provide

a comprehensive list of constructions that will meet the above requirements.

Information for Builder/Developer:

Tarion’s Builder Bulletin B19R requires the internal design of condominium projects to integrate

suitable acoustic features to insulate the suites from noise from each other and amenities in

accordance with the OBC, and limit the potential intrusions of mechanical and electrical services of

the building on its residents. It is expected that if Building 19 Certification is needed, an acoustical

consultant will review in greater detail the mechanical and electrical drawings and details of

demising constructions and mechanical/electrical equipment, during design development, to help

ensure that the noise impact of the development on itself is maintained within acceptable levels.

7 Summary and Recommendations

The following list and Table VIII summarize the recommendations made in this report. The reader is

referred to the previous sections of the report where these recommendations are discussed in more

detail.

For transportation noise sources

1. Building 1 should be equipped with central air conditioning systems that will allow the windows

to remain closed. Building 2 should be equipped with forced air ventilation systems with ducts

sized to accommodate the future installation of air conditioning by the occupant. The use of

central air conditioning will exceed this requirement. The location, installation and sound ratings

of the air conditioning devices should comply with NPC-300, as applicable.


2. Upgraded glazing constructions are required for some of the façades of the proposed building, as

indicated in Section 4.3.

3. Warning clauses should be included in the property and tenancy agreements and offers of

purchase or sale to inform future owners/occupants of the noise issues and the presence of the

roadways, as indicated in Section 4.4.

LR/DR – Living Room/Dining Room BR – Bedroom OBC – Ontario Building Code

For stationary noise sources

1. Two make-up air units were assumed for each proposed mixed-use building. This rooftop

equipment should be selected to have a sound power level rating of 90 dBA or less.


2. If alternate rooftop units are chosen or the location of the mechanical units are modified, an

acoustical engineer should verify that with the selected HVAC equipment and locations

acceptable sound levels will result at all offsite residential receptors.

3. Tarion Builder’s Bulletin B19R requires that the internal design of condominium projects

integrates suitable acoustic features to insulate the suites from noise from each other and

amenities in accordance with the OBC, and limit the potential intrusions of mechanical and

electrical services of the buildings on its residents. If B19R certification is needed, an acoustical

consultant is required to review the mechanical and electrical drawings and details of demising

constructions and mechanical/electrical equipment, when available, to help ensure that the noise

impact of the development on itself are maintained within acceptable levels.

7.1 Implementation

To ensure that the sound control recommendations outlined above are properly implemented in the

site design, it is recommended that:

1) Prior to the issuance of building permits for this development, a Professional Engineer qualified

to perform acoustical engineering services in the Province of Ontario should review the

mechanical drawings and specifications for the mechanical equipment to certify that the MECP

sound levels will be met at all offsite noise sensitive receptors.

2) Prior to the issuance of occupancy permits for this development, the Municipality’s building

inspector or a Professional Engineer qualified to provide acoustical engineering services in the

Province of Ontario to certify that the suggested noise control measures have been properly

installed and constructed.

3) Prior to the issuance of building permits for this development, a Professional Engineer qualified

to perform acoustical engineering services in the Province of Ontario should review the

architectural plans and building elevations to refine glazing requirements based on actual

window to floor areas ratios.
