FIRST PLACE | 2019 ASHRAE TECHNOLOGY AWARD CASE STUDIES

Built for the 1976 Summer Olympics, the Olympic Park is now a multipurpose venue for events, sports, and ofﬁces. Their decadesold HVAC infrastructure was upgraded in an integrated deep retroﬁt designed to achieve the Park's operational, ﬁnancial, and
environmental outcomes.

The Montreal Olympic Park had a critical need to
upgrade obsolete equipment, much of which dated back
to the facility's original construction in 1976. Rather than
replacing equipment piece by piece, the Olympic Park
opted to consolidate all upgrades in a single deep retroﬁt
using a performance contracting approach guaranteed
to reduce energy consumption by 31% and greenhouse
gas emissions by 57%.
The Olympic Park initially
intended to perform one-for-one
equipment replacements in a series
of separate retroﬁts, anticipating
a $20 million asset renewal budget and an eight-year timeframe.
Instead, they changed course,
launching a request for proposals
for a single integrated project that
would replace all outdated equipment while redesigning their district
heating and cooling networks for
improved energy efﬁciency.
The results are compelling: the
deep retroﬁt was completed within
36 months, using only $6.5 million of the Olympic Park's asset

renewal budget. The facility's energy
savings-to the order of $1.55 million per year-already exceed the
guaranteed savings by 19%. These
savings are leveraged along with
subsidies to fund the bulk of the
project. Greenhouse gas emissions
are reduced by 4,560 metric tons per
year, an equally important outcome
for this government-owned asset.

Project Site

The Olympic Park is a landmark in
Montreal, receiving over 3 million
visitors every year. It includes the
iconic Montreal Tower-the tallest
inclined tower in the world-and
the Montreal Olympic Stadium, one
of the world's largest covered stadiums with a gross square footage of
638,400 ft² (59,309 m²) and a seating capacity of 56,000 in the stands.
