Prerequisites 

Co-requisite: ENME 332

Description 

Trends in energy resources and technologies, followed by energy audit/analysis of both residential and commercial facilities. Energy accounting procedures for electrical, mechanical and HVAC systems and respective life-cycle cost analysis. Students will gain hands on experience conducting energy audit, as well get introduced to annual energy consumption/ analysis simulation tools.

Goals 

Students will gain hands on experience conducting actual residential and commercial energy audits, preparing professional reports, and presenting it to the client. Successful completion of this course will equip students with the terminology, knowledge and practical experience necessary to perform energy audits on both residential and commercial facilities.

Topics 

This course is designed to provide students with the necessary knowledge and skills to perform energy audit/analysis on commercial and residential buildings and facilities. Energy accounting procedures for electrical, mechanical and HVAC systems will be covered, along with relevant life-cycle cost analysis. Fundamental building science principles will be introduced in the context of energy auditing. Building energy simulation tools, such as eQuest, as well as other widely known commercially available software will be introduced.  Topics include:

Global Energy Resources:
  • World and national energy resources
  • Current status and future projections for energy and water
  • Opportunities now and projected 2050 needs
Understanding energy consumption costs
  • Analysis of power purchase
  • Utility rate schedules
  • Tariff, peak hour, electric load, electric billing calculation
Electricity supplier and pricing:
  • Electricity supplier
  • Tariff, peak hour, electric billing calculation, electric load etc.
Energy audit procedures for commercial and residential facilities:
  • Analysis of Energy Audit: ASHRAE levels I, II, and III
