Technical FAQs 4

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 site energy vs source energy?

Site energy vs. source energy: what’s the difference? Site energy accounts only for the energy used directly by your property, as reflected on your utility bills. It is considered to be the simplest way to measure a building’s energy consumption.

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 score?

By taking all energy use into account, the score provides a complete assessment of energy efficiency in a building. 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.
