6 FAQs about Basic functions of site energy

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.

Why is source energy more important than site energy?

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. Converting to source energy has a major effect on electricity (factor of 3), and has a small effect for fossil fuels like natural gas. So what difference does this make?

What is the difference between source energy and site energy?

Source energy is the amount of primary energy consumed in supplying secondary energy to a building. The power generation, transmission, and delivery of source energy to the site results in losses. As a result, source energy is nearly always less efficient than site energy.

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.

What is source energy?

Source energy has a larger scope, referring to the amount of energy produced at a power source for a given end use. Source energy is the amount of primary energy consumed in supplying secondary energy to a building. The power generation, transmission, and delivery of source energy to the site results in losses.
