2014 ASHRAE TECHNOLOGY AWARD CASE STUDIES

The renovation of the Otto
Maass Building's laboratories,
mechanical rooms and distribution shafts for lab areas reduced
the annual building energy
consumption by 59%. Efficiency
measures focused primarily on
heat recovery and airflow control based on user needs.

Efficient Labs
For University

BY NICOLAS LEMIRE, ENG., HFDP, MEMBER ASHRAE; PIERRE-LUC BARIL, ENG., HFDP; AND ÉMILIE L'ITALIEN LE BLANC, ENG., ASSOCIATE MEMBER ASHRAE

BUILDING AT A GLANCE

Otto Maass
Laboratory Building
Location: 801 rue Sherbrooke Ouest Montreal, Quebec, Canada (McGill University Downtown Campus)
Owner: McGill University
Principal Use: Education and research in
chemistry
Includes: Teaching and research laboratories, classrooms, lounge, large lecture hall
Employees/Occupants: 726
Gross Square Footage: 140,000
Conditioned Space Square Footage: 125,000
Substantial Completion/Occupancy: July 2011
Occupancy: 100%

Because the mechanical system supplying the lab
area of the Otto Maass Building at McGill University
in Montreal had not been renovated since 1964, the
building was one of the largest energy consumers
on campus. Following a renovation, building energy
consumption dropped from 13% to 5% of the total
energy consumed on the entire campus.
Sixty percent of the building's 140,000 ft2 (13 000 m2)
is labs. Prior to renovation, in the laboratory area the
average fume hood density was 19 chemical fume
hoods per 5,000 ft2 (465 m2). The building's ventilation system operated at a constant flow rate of 135,000
cfm (63 700 L/s) and operated 24/7. Steam was generated from the power plant (natural gas) and a 850 ton
(2990 kW) local chiller was located in the penthouse.

Nicolas Lemire, eng., is president and principal; Pierre-Luc Baril, eng., is associate and design engineer; and Émilie
L'italien Le Blanc, eng., is design engineer at Pageau Morel in Montreal.
