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 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.

How is site energy delivered to a facility?

Site energy may be delivered to a facility in one of two forms. Primary energy is the raw fuel that is burned to create heat and electricity, such as natural gas or fuel oil. Secondary energy is the energy product created from a raw fuel, such as electricity purchased from the grid or heat received from a district steam system.

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.

Quality of the pipes, tank?

How does a solar water heater work?

A solar water heater is typically comprised of solar collectors which absorb solar energy, and a system to transfer the heat to the water. There are two main types of solar water heaters: passive systems, which rely on natural convection to move heated water, and active systems, which use pumps for circulation.

How long do solar water heaters last?

Built for the long haul, solar water heaters offer impressive longevity. Most systems can reliably serve a household or business for up to 20 years 5 if not more, much longer than conventional gas or electric tank water heaters.

What is the max temp of a solar water heater?

5.) The max. attainable temp. of a solar water heater is a function of the design. Under no flow (stagnation) conditions with no, or malfunctioning, relieving devices, temps. in a flat plate under full sun can easily rise to ~ 150 deg. F. or more above the ambient temp.
