Rick Quirouette is a senior building science
specialist with over thirty years of experience in building
research, design, construction and performance. He is
specialized in building envelope investigations, design review
services for architects and engineers and has undertaken
numerous research and development assignments for government and
manufacturers. Assignments include projects in Canada, the USA
and Australia. He is an accomplished communicator through the
many clinics, workshops and seminars presented across Canada.
He has also written extensively on most topics related to
building envelope performance and durability to include air
barrier technology, rain penetration control, the dynamic buffer
zone (DBZ) and energy conservation.
has undertaken over two hundred on-site investigations on roofs,
cladding and wall systems, windows and glazing systems to
determine precise causes and to develop cost effective remedial
repairs. Symptoms and damages investigated include the
determination of the causes of rain penetration, the causes of
air leakage through walls, windows and roofs, the causes of high
energy use, poor temperature control and the causes of damages
to exterior cladding and exterior wall elements. This
experience includes investigations on most types of residential,
commercial, industrial and institutional buildings. From time
to time investigations lead to litigation. Rick is experienced
with documentation required as well as testifying in discoveries
and at trial.
design development and/or review of a new building envelope,
restoration, rehabilitation or remedial repair is a specialty
service offered to owners, architects, engineers, builders and
manufacturers. From knowledge gained through investigations and
continuing studies of envelope performance and durability, Rick
may provide valuable assistance in the application of building
science principles to the development and design of most types
of envelope assemblies. Wall systems expertise includes brick
veneer steel studs, metal and glass curtain walls, architectural
precast, stucco and EIFS claddings and metal buildings. Review
emphasis is usually directed to the detail design of joints,
material and technology selection and compliance to part V of
the National Building Code of Canada.
Research & Development
is often involved in building science research and a leader in
the application of research findings to practice. He developed
the basic principles of air barrier design in the early eighties
while at IRC/NRC. He further developed and explained the
essential difference between vapour retarders and air barriers.
Since that time he has undertaken numerous research projects
related to determining cost effective ways of developing air
barrier details for various roof and exterior wall
applications, and how to determine the structural requirements
of air barriers. He has also explored and determined the
effectiveness of the rainscreen principle applied to brick
veneer claddings, the importance of compartmentalization and the
necessity of the air barrier system to the performance of the
rainscreen system. Recently, he was engaged by PWGSC to develop
the design requirements for a dynamic buffer zone (DBZ)
application for existing masonry buildings required to provide
high indoor humidity.
is also involved in the transfer of technology. The information
gained from investigations and research is organized and
presented to industry practicing members through clinics,
workshops and seminars. Clinics are 1/2 day programs on a topic
of interest presented to owners, architects, engineers or
manufacturers in the privacy of their offices.

Design Development & Review Assignments
Building envelope design is now recognized as an area of
expertise requiring considerable building science knowledge as
well as field experience with the performance of various wall,
window, and roof systems. With the multitude of difficulties
arising with the performance of recent building projects, and
specifically the rehabilitation of older buildings, it is
prudent to involve a building envelope specialist on your team.
This would minimize the risk of envelope problems after
completion of a project. The knowledge that has been gained,
through investigations as well as research and development, is
made available for the production of quality building envelope
detail design. Rick's experience with design development and
Camelot Court, Nepean, Ontario. This project was
designed by Pie & Richards Architects. I was involved directly
in the development of the air tightness and water penetration
control details for the tilt-up precast (3 storey) connections
as well as the windows and the roof connection details. The
project is currently under construction.
Thunder Bay Airport. This project was designed by IKOY
Architects, Winnipeg, Manitoba. Through Morrison Hershfield
Limited, I have reviewed and modified the design of the metal
and glass curtain wall joint connections to other parts of the
building to include the roof/wall connection, the grade to
curtain wall connection and curtain wall to architectural
precast connection. I also assisted in developing the
performance as well as prescriptive requirements for the metal
and glass curtain wall.
Supreme Court of Canada. This project involved the
re-design of the roof system and third floor including the
exterior wall to arrest further moisture damage and to upgrade
the performance of the envelope to support higher indoor
humidities. I directed the development of all details related
to the roof rehabilitation at Morrison Hershfield. The new
system currently under construction retains its architectural
feature and heritage characteristics but should support fifty
percent humidity in future use.
Solicitor General Building, Ottawa, Ontario. In this
project, under Morrison Hershfield, I was retained by Public
Works Canada to oversee the design development of the building
envelope by the architects. In particular it involved the roof
system, the skylights and sloped glazing details, the
architectural precast panels and the metal and glass curtain
wall. The project is currently under construction.
Ottawa City Hall, Ottawa, Ontario. This project was
designed by Mosha Safdie Architects, with Murray and Murray
Architects producing the working drawings. I was involved with
Murray and Murray to develop the conceptual and detail design
for the exterior walls of the new city hall. Design development
also included, material selection for air and vapour barriers,
insulation and rainscreen claddings. The construction of this
project was completed in 1992.
Centre d'acceuil pour personnes agées, Buckingham, Québec.
This project involved the replacement of the existing roofs with
a new system. The replacement was designed by Kinmond Murfitt
Architects. Under Morrison Hershfield, I directed the
development of the rainscreen roof system, based on the NRC
double drained and vented concept. The project was completed in
Saskatoon General Hospital, Saskatoon, Manitoba. In
cooperation with Con-Force precasters, I was involved in a major
review of the architectural details involving precast panels.
Dozens of modifications were presented to attain better air
tightness performance but most important a maintenance free
exterior wall and cladding system.
Tiley Building, Ottawa, Ontario. This building is 28 years
old. The exterior brick veneer was severely damaged from
moisture. The challenge was to rehabilitate the solid masonry
wall with an insulated modern rainscreen brick veneer system
without altering the architecture or other heritage
characteristics. The design of the wall system was successfully
achieved within the budget and schedule provided. The new
technology for air barrier systems and for rainscreen technology
were applied. The project is nearing completion.
Emcon Building, Nepean, Ontario. Reviewed and recommended
for the window system at EMCON. Produced sketches of
recommended repair and identified source/supplier of materials.

provided an interpretation of article 126.96.36.199 of the 1985
Supplement to the National Building Code of Canada.
(11) Sir John Carling, Ottawa, Ontario. Participated in a
value management/brainstorming session (one day). Determined
the most cost effective solutions for the rehabilitation of the
building envelope of the Sir John Carling building.
(12) Piscine Ste. Julie, Montréal, Québec, Reviewed
preliminary conceptual drawings, also reviewed building envelope
systems to include masonry wall details, window systems and roof
system design. Humidification and pressurization strategies
were also discussed.
(13) Princess Margaret Hospital, Toronto, Ontario. One day
visit to undertake a cursory review of the design and
construction of the rainscreen architectural precast wall system
and of the construction documents and specifications. I also
undertook a sample review of the current site conditions of
venting, drainage, the air barrier system and the details for
(14) Secure Facility, Ottawa, Ontario. I provided several
services for the Barry Hobin Architects' office. Consulted on
ventilation strategy for the roof spaces. Reviewed letter
regarding fire protection and roof ventilation, re-calculated
and re-designed vent area openings required on basis of sealed
soffits. Provided many telephone consultation on this project.
Initiated building envelope design review.
(15) Overbrook Day Care, Ottawa, Ontario. I provided
consultation services on the envelope design of this addition to
an existing school.
problem occurs with a roof, wall or window, an owner or designer
will usually call upon a contractor or a material supplier to
diagnose the building envelope deficiency. While this is a
normal and reasonable approach, it usually results in expensive
and costly repairs often not justified because the contractor or
supplier is not skilled or paid for a diagnostic while he is
skilled and paid for new construction and replacement repair.
It is for this reason that a building envelope problem should be
investigated by a specialist in envelope performance and
durability, if only to identify the correct cause and to
recommend sensible cost effective repairs. QBS has the
knowledge, experience and expertise. The projects that follow
are a few of the investigation undertaken by Rick Quirouette and
