1. INTRODUCTION
ECOH Management Inc. (ECOH) was retained by the Toronto District School Board to
conduct an assessment at John Fisher Public School for the purposes of particularizing and prioritizing of window replacement and installation of air-conditioning systems at the school as recommended by ECOH in the Phase II Risk Assessment Report, dated April 21, 2017.
Mr. Rob Fernandes and Ms. Seema Sharma of ECOH completed the assessment of the subject
on May 9, 2017. This report summarizes the findings of the assessment and associated
recommendations. Site photographs are provided in Appendix I. Drawings indicating the
prioritization of the window replacement are provided in Appendix II.
2. METHODOLOGY
The prioritization of the window replacement took into consideration the design, condition and
location (i.e. proximity to construction, room usage, etc.) of the windows and how these factors
would influence the potential for noise and dust infiltration associated with the construction
project that is to be completed to the west of the school property. For the installation of air-
conditioning systems, the prioritization took into consideration the likelihood of utilizing
windows for ventilation with respect to the potential for noise and dust infiltration associated
with the construction project. Based on the aforementioned factors, ECOH has proposed three
categories for prioritization of the window replacement and installation of air-conditioning
systems as follows:
Category 1: The windows in these locations are at greatest risk for noise and dust
infiltration and should be replaced prior to commencement of the adjacent construction
project. As these locations are also in closest proximity to the construction area, the windows will not likely be used for ventilation purposes. These locations should, therefore, be
given highest priority for the installation of air-conditioning systems.
Category 2: The windows in these locations are at a lesser risk for noise and dust infiltration
than Category 1 and includes newer and/or fixed units. These locations should be monitored
for noise and dust infiltration during the period when construction activities are occurring
below grade and the windows replaced, as required. If windows cannot be used for
ventilation, consider the installation of air-conditioning systems.
Category 3: The windows in these locations are at a lesser risk for noise and dust infiltration
than Category 2 and should be replaced once the construction activities are occurring above
grade. If windows cannot be used for ventilation, consider the installation of air-conditioning
systems.

3. OBSERVATIONS
For the purposes of the assessment, the subject building is considered to be facing south. The
following was noted during the assessment:
Basement
South side - Room B1 and B2
On the south wall - There are 5 single hung windows in the classroom. These are newer plastic
and wood composite frame, double glass pane windows with gaskets all around them. These
are vertically opening windows. In room B2 the central window needs adjustment, it does not
slide all the way down.
East side - Room B3
This room had mix of fixed and operable windows
On the northeast wall - A row of 5 fixed single pane wooden frame windows is present and on
the east, corner a single fixed glass pane wooden frame window is present
On the east wall - There are present 2 operable single hung wooden frame windows with no
gasket around them and the windows do not seal fully. These are vertically opening windows
Boys washroom
West wall - There is a row of 4 newer vinyl windows along wall (2 fixed and 2 operable). The
operable sections are equipped with appropriate gaskets.
Northwest side-Lunch room
This is located at the northwest corner of the school building. On the north wall - There are 2
sets of windows along the wall. On the west end of the room the windows are present as a row
of 4 windows and toward the east end of the room they are present in a set of 5. They are single
hung, vertically opening, single pane wooden frame windows with brush gaskets on the
bottom. The second window from the west end has damaged brush gasket and fifth window is
also damaged, all windows sashes are loose.
First Floor
North west side- Classroom 2 and South side- Classroom 3
Row of 5 double hung sash windows is present on the north wall of the room. The upper and
lower sashes overlap in the center and slide up and down in wooden frame. The windows are
single glass pane and open vertically. There are present brush gaskets on the sides and rubber
gaskets at the bottom. The gaskets are not providing adequate air sealing as there are air drafts
from the bottom of the window pane when fully closed. The upper windows are operable with
a pulley system and rope. Windows in the upper row do not have any weather stripping or
gaskets around them. All the windows have play in and out of the frame. The glass is thinner
than windows in the basement.
North side – Classroom 1 and South side - Classroom 4
Row of 5 double hung sash windows is present on the north wall of the room 1 and south wall
of room 4. The upper and lower sashes overlap in the center and slide up and down in wooden
frame. The windows are single glass pane and open vertically. There are present brush gaskets
on the sides and rubber gaskets at the bottom. The gaskets are not providing adequate air

sealing as there are air drafts from the bottom of the window pane when fully closed. The upper
windows are operable with a pulley system and rope. Windows in the upper row do not have
any weather stripping or gaskets around them. In Room 1, bug screens are present on lower
windows, on the first window on the west side there is a squirrel nest and the wooden frame is
eaten. In room 4, the fourth window from west side has no bottom gasket.
South side - Classroom 5, Classroom 6, Classroom 7
Row of 4 double hung sash windows is present on the south wall of the room in classroom 5
and 6 whereas row of 5 windows is present in classroom 7. The upper and lower sashes overlap
in the center and slide up and down in wooden frame. The windows are single glass pane and
open vertically. There are present brush gaskets on the sides and rubber gaskets at the bottom.
The gaskets are not providing adequate air sealing as there are air drafts from the bottom of
the window pane when fully closed. The upper windows are operable with a pulley system and
rope. Windows in the upper row do not have any weather stripping or gaskets around them. In
classroom 6 the windows have foam gasket on the bottom surface. There is presently a fixed
window in the washroom attached to classroom 5 whereas an outward opening hinged window
is present in washroom attached to classroom 6.
East side - Classroom 9
Row of 5 single pane fixed windows is present in the classroom. The inside of the classroom
was quieter as compared to the other classrooms, less outside noise was heard.
Far west wall - Classroom 11
Same as classroom 5,6 and 7. An additional window is present on the north end of the wall
Second Floor
North side- Room 13 and room 12
Windows same as classroom 2 on the first floor. Windows in Room 13 do not close fully
(teacher has installed tape along bottom edge to block drafts).
Far west side- classroom 21, 22 and 23
Windows same as classroom 2 on the first floor
South side- Classroom 14, 15, 16, 17, and 18
Windows - the windows are in row of 5 windows and are relatively newer window frames. The
top window is fixed though provision for it to slide in the frame is present. The frame has a
plastic insert/lip around it should should reduce dust/noise infiltration relative to wood-only
frames.
East wall – Classroom 19
The windows are double pane fixed windows, no outside noise was perceived within the
classroom.
East side- Classroom 20
There are 5 windows which are double sash hung windows. There are brush gasket on the
bottom surface of the windows

General
Gaps and missing gaskets were noted around the entrance doors of the building, including the
doors along the west elevations of the building which face the construction area.
Vents (exhaust and/or supply) were noted throughout the school. The majority of the
ventilation systems in the school did not appear to be operating at the time of assessment.
4. RECOMMENDATIONS
Based on the findings of the assessment, ECOH offers the following recommendations for
consideration:
1. Replace the windows in the following locations as Category 1 priority: Basement Lunch Room, Classrooms 1-4, 11-13, 21, and 22
2. Monitor and replace as required the windows in the following locations as Category 2
priority: Basement Boys Washroom, Classrooms B1-B3, 5, 6, 9, 14-17 and 19, library,
offices, stairwells, Room 26 and hallways
3. Replace the windows in the following locations as Category 3 priority: Classrooms 7, 8, 18, 20 and 23, Room 20A, and office beside Classroom 17
4. The replacement windows should be double pane glass and the frame should have as much sound attenuation as the double pane glass components. Any operable sections of the windows must be equipped with adequate seals/gaskets to prevent dust and noise infiltration when the window is in the closed position.
5. Air-conditioning systems should not generate excessive noise and must be installed in such a manner that does not compromise the sound attenuation provided by new windows, if window-mounted air-conditioning systems are used.
6. Ensure proper seals are present around the perimeter of entrance doors, particularly along the west elevations.
7. Ensure existing ventilation systems are inspected and fully operational
