Zero Energy Buildings
Steven G. Liescheidt, P.E., CCS, CCPR
This one hour online course discusses how a net zero-energy building is a residential or commercial building with greatly reduced energy needs through efficiency gains such that the balance of energy needs can be supplied with renewable technologies. Four well-documented definitions—net-zero site energy, net-zero source energy, net-zero energy costs, and net-zero energy emissions—are studied; pluses and minuses of each are discussed.
This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of course materials.
At the conclusion of this course, the student will learn about:
This course is intended for mechanical and energy engineers.
Benefit for Attendee
Attendee of this course will be able to understand the basics and various definitions of Zero Energy Buildings (ZEB’s).
In concept, a net Zero Energy Building is a building with greatly reduced energy needs through efficiency gains such that the balance of the energy needs can be supplied by renewable technologies. Despite the use of the phrase “zero energy,” in this course material; there is a lack of a common definition or a common understanding of what it means. This course material uses a sample of current generation low-energy buildings to explore the concept of zero energy, what it means, why a clear and measurable definition is needed, and progression toward the Zero Energy Building goal.
This course is primarily based on the Technical Report NREL/TP-550-41957, December 2007 “Assessment of the Technical Potential for Achieving Net Zero-Energy Buildings in the Commercial Sector"
Each of the leading-edge case study buildings in this course source document demonstrates the progress toward achieving Zero Energy Building goals in real-world examples. The zero energy definition affects how buildings are designed to achieve the goal. The definition can emphasize energy efficiency, supply-side strategies, purchased energy sources, utility rate structures, or whether fuel-switching and conversion accounting can help meet the goal.
