Site and source energy
Site energy refers to the total amount of energy consumed at a specific location, such as a building, facility, or campus. This includes the energy used to power the lights, heating and cooling systems,

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) and secondary

What are Site Energy and Source Energy?
Site Energy is the combination of primary and secondary energy that you buy directly for use at your building. It is calculated in Portfolio Manager by converting each of your fuels into kBtu,

Energy services are what humans care about, like hot showers and cold beverages. There are energy losses each time we convert energy from one form to another. Energy systems are most efficient
Contact Us4 Frequently Asked Questions 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.
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.
