Unit 11: Project Cash Flow

Siemens was chosen because its scope of work was innovative and dealt extensively with Notes
converting costly maintenance improvements into significant savings.
As Dr. Albert Maringer, President and CEO of Siemens Canada Ltd., explained, "It was our
goal to provide the most innovative solutions to reduce future energy costs and provide
a new infrastructure program that will reduce overall maintenance requirements at the
Mint."
Once the ESC was selected, the process of preparing a detailed feasibility study and
negotiating the final contract was underway. On March 24, 2005, the Mint and Siemens
Building Technologies Ltd. finalized and signed the EPC.
Project Scope

The proposed total costs of the energy efficiency improvements at the Mint are estimated
at $8 million. Potential cost savings are estimated to reach as high as $1 million annually.
The project's design integrates a variety of systems, technologies, practices and programs,
including the following energy efficiency measures:
 Installation of new chillers and boilers in response to the rising cost of purchasing
steam from an outside supplier. The feasibility study conducted by Siemens concluded
that the installation of new chillers and boilers in the facility would be the most
economical solution for the Mint.
 Replacement of aging air compressors with new energy-efficient ones to increase
the reliability of operations and lower maintenance costs.

 Installation of two new supply air units with variable air volume (VAV) terminal
boxes to replace old fan coils. The VAV system varies the amount of air delivered to
ensure workspace conditions are maintained. The system also substantially lowers
energy and maintenance costs.
 Modernization of the filtration unit in the Mint's process operation to increase
water filtration capacity and reduce energy use.
