How much energy do plug loads use?
Plug loads as a share of overall building energy use is higher in energy efficient buildings. In minimally code-compliant office buildings, plug loads may account for up to 25% of total energy consumption. But in high efficiency buildings, plug loads may account for more than 50% of the total energy consumption.
How is plug load calculated?
Calculating Load
- Add together the wattage capacity of all general lighting branch circuits.
- Add in the wattage rating of all plug-in outlet circuits.
- Add in the wattage rating of all permanent appliances (ranges, dryers, water heaters, etc.)
- Subtract 10,000.
- Multiply this number by .
- Add 10,000.
What is plug load management?
Plug load management solutions use a combination of “smart” outlets, software and integration tools to manage devices and collect building data. Smart plugs and inline hardware collect data from connected devices and transmit it over the existing 802.11 Wi-Fi network for measurement, tracking and control purposes.
How do you reduce plug loads?
A 5-Step process for plug load reduction:
- Review. Identify your needs, inventory your equipment and focus on the devices that use the most energy–usually, that’s the equipment you use the most.
- Remove. Eliminate or unplug unnecessary devices.
- Replace.
- Reduce.
- Retrain.
What are plug and process loads?
Plug and process loads (PPLs) are building electrical loads that are not related to lighting, heating, ventilation, cooling, and water heating, and typically do not provide comfort to the occupants.
What is a miscellaneous plug load?
Miscellaneous electric loads (MELs) in buildings are electric loads resulting from electronic devices not responsible for space heating, cooling, water heating, or lighting.
What are the 5 types of electrical loads?
Electrical Loads can be classified according to the nature of the load as follows:
- Resistive Electrical Loads.
- Capacitive Electrical Loads.
- Inductive Electrical Loads.
- Combination Electrical Loads.
How many amps do I need?
Divide the number of watts required by the volts to determine the needed amperage. For example, a 120-watt device, requiring 1,200 volts requires 10 amps.
Where are controlled receptacles required?
The Energy Standards require both controlled and uncontrolled 120-volt receptacles in lobbies, conference rooms, kitchen areas in office spaces, copy rooms, and hotel/motel guest rooms.
What energy is plug?
Electrical outlets (also known as outlets, electrical sockets, plugs, and wall plugs) allow electrical equipment to connect to the electrical grid. The electrical grid provides alternating current to the outlet. There are two primary types of outlets: domestic and industrial.
What is a plug load LEED?
Plug load is the energy used by products that are powered by means of an ordinary AC plug (e.g., 100, 115, or 230 V). This term generally excludes building energy that is attributed to major end uses (HVAC, lighting, water heating, etc.)
What is miscellaneous heat load?
