As energy conservation and alternative energy production become a greater priority throughout the world, governments are playing a larger role in steering the transformation of how our energy is produced and consumed.

This course content allows students to become more aware of the type of involvement government and regulatory agencies have in the energy field and the influence these organizations have on the clean energy industry and the future job market in clean energy. Students are introduced to the theories and types of regulations and policies that apply to energy efficiency and renewable energy projects, mostly from a Canadian perspective. As some of our energy legislation is based on examples from other countries, international energy policy examples are also explored.

The broad and evolving area of federal, provincial and municipal government incentive programs for energy conservation, renewable energy use, and green-house gas emission reductions are discussed. The role of regulatory bodies in the renewable energy sector and the licensing of energy efficiency and renewable energy practitioners are reviewed.

This course focuses on the design of complete renewable energy systems to meet client needs. Emphasis is given to the process of designing rather than just knowledge of the technology. Working in teams, students perform all aspects of a project design including customer needs assessment, technology selection, detail component specification, and cost-benefit analysis. Lecture and lab topics support typical detailed design activities and introduce students to mechanical design including forces, stresses, fasteners, and the sizing of pumps, piping, and heat exchangers. Normal business processes associated with design activities such as understanding a customer's `Request for Proposal' and legal liability are included.

Prerequisite(s): ESET410

In this course students undertake a substantial energy auditing project for an external organization. The external organization acts as the client and the students provide a service at a level similar to that expected from practitioners in the field. The project is substantial in the sense that it requires significant work to assess client requirements, to gather background data, and to report findings in a professional manner. Working as a team, students interact with faculty, outside professionals, and the client organization to gather data and create a preliminary building assessment.

Prerequisite(s): ESET431 + ESET410

This is an advanced course in energy control systems. The course examines programmable, micro-processor based HVAC control systems and large scale distributed control systems for energy management in buildings.

Prerequisite(s): ESET410 + ESET568

In this course students complete an energy audit of an institutional, commercial or industrial (ICI) facility. The energy audit involves further analysis of energy usage and development of suggestions for saving energy and/or costs. Recommendations for the project client may involve the preliminary specification of energy systems equipment. The final project report also includes an analysis of the financial costs and benefits of the proposed changes. The course is organized to mimic the team based structure that students are likely to find in the commercial energy auditing or engineering services business. Students are required to develop project schedules and to report their progress. Report results are communicated to the client in a professional presentation.

Prerequisite(s): ESET630

This course develops awareness of the standards used to define energy efficient building in the residential, commercial, institutional and industrial sector. Standards currently in use in provincial and federal will be explored. Typical standards and design approaches that will be presented include LEED™, ASHRAE90.1, Passive House, BOMA Best, Net Zero Energy and the National Energy Code of Canada for Buildings (NECB).

In this course, students practice the skills to develop and execute a project management plan. Microsoft Project is the primary tool used in this course, complemented by other software tools such as Microsoft Planner and Excel. Each student completes a project management plan that is reasonable, cost effective, flexible and adaptable should obstacles be encountered. Other aspects of project management addressed include stakeholder engagement, scope of work, contracts, team leadership, and compliance with relevant legislation.

The work placement course in the Energy Systems Engineering Technology program is the final component of the student's college learning experience. This course gives the student the opportunity to be involved in learning and work activities that relate to careers in Energy Systems. It is intended that the course contribute to the student's professional growth and development as an Energy Systems Technologist. The workplace experience is important to both the student and to future employers. Placement in a real work environment provides the student with an opportunity to understand the significance and importance of their classroom learning. Employment opportunities are available from organizations that have indicated a commitment to technical and professional learning.
