Home energy management system
Home energy management (HEM) enables domestic consumers to take part in demand side activities. But, it confronts some problems resulted from the uncertainties of renewable energy resources and consumers’ behaviour; while, the domestic consumers aim at the highest level of comfort that should be considered by minimizing the “response fatigue” phenomenon.
The term Energy Management System can also refer to a computer system which is designed specifically for the automated control and monitoring of those electromechanical facilities in a building which yield significant energy consumption such as heating, ventilation and lighting installations. The scope may span from a single building to a group of buildings such as university campuses, office buildings, retail stores networks or factories. Most of these energy management systems also provide facilities for the reading of electricity, gas and water meters. The data obtained from these can then be used to perform self-diagnostic and optimization routines on a frequent basis and to produce trend analysis and annual consumption forecasts. Energy management systems are also often commonly used by individual commercial entities to monitor, measure, and control their electrical building loads. Energy management systems can be used to centrally control devices like HVAC units and lighting systems across multiple locations, such as retail, grocery and restaurant sites. Energy management systems can also provide metering, submetering, and monitoring functions that allow facility and building managers to gather data and insight that allows them to make more informed decisions about energy activities across their sites.
A system in which a dispatcher can monitor and control the flow of electric power by opening and closing switches to route electricity or to isolate a part of the system for maintenance. It is also used to control the amount of generation needed to serve
The International Organisation for Standardisation (ISO) is an independent organisation responsible for the production of voluntary international standards. ISO have 165 member countries with a Central Secretariat based in Geneva. The name ISO is derived from the Greek ‘isos’ which means equal.
ISO 50001:2011 ‘Energy management system-Requirements with guidance for use’ sets out the requirements for energy management systems. It is applicable to all variables affecting energy performance that can be monitored and influenced by an organisation. It does not detail performance criteria with respect to energy.
ISO 50001:2011 is relevant to all organisations wishing to ensure that they conform to a stated energy policy and wishing to demonstrate this to others.
