Score

Designation of energy efficiency describing a building's performance on a continuous scale instead of into an energy class. The result of the rating process, and sometimes, confusingly called a rating (US). [Source: Institute for Market Transformation]

Service Providers

The service providers intervene to insure the normal operation of the building during its use phase (e.g. the heating operating companies, the maintenance firms, the electricity, water and gas providers, etc.). [Source: IEA Annex 31 Glossary]

Site Energy

The value of the energy delivered to the facility (or site), excluding that used to produce or deliver the energy. This is sometimes called useful energy. [Source: EnergyIQ, Lawrence Berkley National Laboratory]

Small Scale Cogeneration Unit

Small-scale cogeneration unit means a cogeneration unit with installed capacity below 1 MWe. [Source: EU Directive 2012/27/EU on Energy Efficiency]

Smart Metering

Smart metering system means an electronic system that can measure energy consumption, providing more information than a conven­tional meter, and can transmit and receive data using a form of electronic communication. [Source: Energy Efficiency Directive 2012/27/EU]

Solar Heat Gains

Heat provided by solar radiation entering, directly or indirectly (after absorption in building elements), into the building through windows, opaque walls and roofs, or passive solar devices such as sun spaces, transparent insulation and solar walls [Source: International ISO Standard 13790- Energy performance of buildings- Calculation of energy use for space heating and cooling (2008).]

Solar Irradiation

Incident solar heat on a surface, per area of surface.[Source: International ISO Standard 13790- Energy performance of buildings- Calculation of energy use for space heating and cooling (2008).]

Source Energy

Source energy is a measure that accounts for the energy consumed on site in addition to the energy consumed during generation and transmission in supplying the energy to your site. [Source: U.S. Environmental Protection Agency]

Space Cooling

Process of heat extraction for thermal comfort. [Source: EN 15603 Energy performance of buildings - Overall energy use and definition of energy ratings]

Space Heating

Process of heat supply for thermal comfort. [Source: EN 15603 Energy performance of buildings - Overall energy use and definition of energy ratings]

Split Incentives

Split incentives refer to situations where a person investing in energy efficiency improvement does not reap the corresponding financial benefits and as such has no incentive to make it happen. [Source: IEA (2010) Money Matters]

Sports Facility

A sports facility can be defined as a venue where sporting activities take place such as a sports hall, swimming pool or gym. [Source: GBPN]

Standard Values

Standardised input data, including climate, building use, and occupant-related inputs, used in the simulation of a building's performance under standardised conditions for an asset rating. [Source: Immovalue]

State of the Art

The state of the art is the highest level of development, as of a device, technique, or scientific field achieved at a particular time. It also refers to the level of development (as of a device, procedure, process, technique, or science) reached at any particular time as a result of the latest methodologies employed. [Source: Wikipedia]

Subsidy

A subsidy can be defined as a financial contribution made by (or on behalf of) a government or public body which confers a benefit to the recipient. [Source: European Commission]

Substantial Refurbishment

Substantial refurbishment means a refurbishment whose cost exceeds 50% of the investment cost for a new comparable unit. [Source: Energy Efficiency Directive 2012/27/EU]

Supplied Energy

Purchased energy supplied to the property, for example in the form of natural gas, oil, district heating, district cooling, groundwater cooling, electricity or biomass. [Source: Danish Building Code Byningsreglementet 2010 (BR10)]

System Thermal Loss

Thermal loss from a technical building system for heating, cooling, domestic hot water, humidification, dehumidification or ventilation that does not contribute to the useful output of the system. A system loss can become an internal heat gain for the building if it is recoverable. Thermal energy recovered directly in the subsystem is not considered as a system thermal loss but as heat recovery and directly treated in the related system standard. Heat dissipated by the lighting system or by other services (e.g. appliances of computer equipment) is not part of the system thermal losses, but part of the internal heat gains.
