The Difference Between Source and 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.

Measuring energy: site energy vs. source energy in ENERGY

For buildings that purchase raw fuel (such as natural gas) and convert it to power on-site, a site energy measurement would account for the losses that occur during this conversion, because

Site vs Source Energy

Site energy is the energy which is consumed at the final destination of the power generation cycle, and to simplify, is the amount of energy shown on a utility bill. It is the power

Source vs. Site Energy Solutions

Site energy refers to the amount of energy metered at the point of use (e.g. consumed by a building). Site energy may refer to both primary energy (natural gas or fuel consumed on site)

Site vs Source Energy

Site energy is the energy which is consumed at the final destination of the power generation cycle, and to simplify, is the amount

4 FAQs about Site Energy Introduction

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 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 a site energy measurement?

For buildings that purchase raw fuel (such as natural gas) and convert it to power on-site, a site energy measurement would account for the losses that occur during this conversion, because site energy is based on the fuel that is purchased.

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.
