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.
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.
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. This is important to understand when considering how efficiently energy is consumed, as well as the emissions impacts of energy consumption.
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.
Does greener energy mean a better 1-100 ENERGY STAR score? Not necessarily. Portfolio Manager offers some credit for green energy generated onsite (e.g. through solar panels or wind turbines).
After you''ve benchmarked your building, you''ll see several performance metrics, including source and site EUI (or energy use intensity). What''s the difference? And which is used for the 1 – 100 ENERGY STAR score?
Site energy: A building-specific term. The amount of energy that enters a residential or commercial building. Includes the primary energy (natural gas, petroleum products, and renewable energy) and the electricity
As a result, Site Energy is not a good metric to compare two different buildings. Source Energy Source Energy is your total primary energy consumption (meaning Site Energy) plus all the delivery and
The difference between site vs source energy is important to understand when considering energy use for buildings.
Source energy, on the other hand, refers to the total amount of primary energy required to generate and deliver the site energy to the location. This includes the energy used to extract, produce, and deliver the
Source vs. Site Energy Solutions When discussing energy efficiency, decarbonization, and greenhouse gas accounting, the terms source energy and site energy are often used. What is the difference
The Energy Intensity Indicators website uses the following terms with their associated definitions. The terms related to various definitions of energy are discussed first. Three separate definitions of energy are
The difference between site and source energy is a vital concept to understand when looking at the energy performance of buildings—failing to account for the difference will result in an apples-to-oranges
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
Does greener energy mean a better 1-100 ENERGY STAR score? Not necessarily. Portfolio Manager offers some credit for green energy generated onsite (e.g. through solar panels or
