Technical FAQs 4

Why is site energy important?

Looking at site energy can help you understand how the energy use for an individual building has changed over time. Site energy may be delivered to a building in one of two forms: primary or secondary energy. Primary energy is the raw fuel that is burned to create heat and electricity, such as natural gas or fuel oil used in onsite generation.

What is site energy?

You’re probably already familiar with site energy, which is the amount of heat and electricity consumed by a building as reflected in your utility bills. Looking at site energy can help you understand how the energy use for an individual building has changed over time.

What is the difference between site energy and source energy?

Source energy is a measure that accounts for the energy consumed on site in addition to the energy consumed during generation and transmission in supplying the energy to your site. Source energy is much more important than site energy if the concern is environmental performance. Site energy is useful because it can be unambiguously measured.

What is energy use?

This includes the energy used to extract, produce, and deliver the fuel sources, such as coal, natural gas, or renewable sources like solar and wind energy. It also includes the energy used in the transmission and distribution of the energy to the site location.
