2013 ASHRAE Technology Award Case Studies

The Biodôme is deeply committed to
protecting the environment and biodiversity. In addition, the building’s energy
costs were consistently high because the
building had some zones that required
constant heating while others required the
removal of excess heat. It was supplied
with chilled water (yearly average 330
tons) and steam (yearly average 3,000
lb/h [0.38 kg/s]) by the neighboring building. The electric demand for the building
was approximately 3,200 kW.
Finally, the electromechanical equipment used for heating, cooling, and
lighting required major upgrades.
Therefore, the institution decided to
go forward with an ambitious energyefficiency retrofit project aimed at significantly reducing energy consumption
and greenhouse gas emissions.

Project Description
An energy saving retrofit was performed
on the building from 2008 to 2010. The
project was carried out as an energy performance contract in partnership with a
firm of energy-efficiency professionals.
Implemented in close partnership with
the Biodôme’s technical services staff,
the project was designed to dig deeper
into the existing energy infrastructure to
reduce costs, upgrade equipment and improve conditions for the collections and
for the people in offices and public areas.
The $8.1 million project reduced energy costs by 52% and greenhouse gas

The chillers—or heat pumps—use R-134a. A 250 ton (879 kW) heat pump is
dedicated to the Sub-Polar Regions where a colder water-glycol mixture is needed.

emissions by 80%. Project costs are being repaid within a 5.2-year period by
guaranteed energy savings and $1.6 million in government and utility incentives.
The project was carried out as an energy performance contract, with the energy
services firm providing all services for a
lump sum. All energy savings and incentives were contractually guaranteed.
The process began with the compilation and analysis of all the building’s
energy bills from the last five years.
One of these years, considered the
most representative, was selected as
the “base year.” The preliminary study
and the detailed study fully met the
requirements of sections 5.3 to 5.5 of
Standard 100-2006, Energy Conservation in Existing Buildings, and “Level

3—Detailed analysis of capital intensive modifications.” Finally, this scope
of services included a project performance monitoring phase and a guarantee by the energy services firm of finan-
