Upgrading a fixture, room or building by installing new lighting fixtures, parts or equipment.
Any change made to an existing structure to reduce or eliminate damage to that structure from flooding, erosion, high winds, earthquakes, or other hazards.
The addition or removal of an item of equipment, or a required adjustment, connection, or disconnection of an existing item of equipment, for the purpose of reducing emissions.
a modification to an existing building.
The replacement of a defective and non-repairable heating or plumbing system in a home with another new system of better quality.
The creation or modification of an urban runoff management system in a previously developed area. This may include wet ponds, infiltration systems, wetland plantings, streambank stabilization, and other BMP techniques for improving water quality and creating aquatic habitat. A retrofit can consist of the construction of a new BMP in a developed area, the enhancement of an older urban runoff management structure, or a combination of improvement and new construction. (Schueler et al., 1992)
The upgrading or adjustment of equipment so that it can be used under altered conditions ; for example, of refrigeration equipment to be able to use a non-ozone depleting refrigerant in place of a CFC.
The installation of a new BMP or improvement of an existing BMP in an already developed area.
To furnish or affix parts or equipment made available after the time of original manufacture, or to modify an existing floor plan or fixtures to new specifications
The modification of an existing building or facility to include new systems or components.
provide with parts, devices, or equipment not available or in use at the time of the original manufacture; "They car companies retrofitted all the old models with new carburetors"
fit in or on an existing structure, such as an older house; "The mansion was retrofitted with modern plumbing"
substitute new or modernized parts or equipment for older ones; "The laboratory retrofitted to meet the safety codes"
Modification of an existing structure, in this case to strengthen against potential damage by earthquakes. This may consist of simply bolting a house to its foundation, or of installing a state-of-the-art shock-absorbing system. For more information on retrofitting homes, buildings, and bridges, see Determining the Safety of Your Home or School from the USGS' The Next Big Earthquake and the FAQ page on earthquake engineering from the Berkeley Seismological Laboratory.
Process of taking an existing web page from an inaccessible form to an accessible form. Many departments have chosen to redesign a new site rather than take on the tedious task of retrofitting.
To install a new BMP or improve and existing BMP in a previously developed area
the addition of new building materials, building elements, and components, not provided in the original construction.
The creation or modification of a stormwater management practice, usually in a developed area, that improves or combines treatment with existing stormwater infrastructure.
To weatherize an existing structure. Also, the process of modifying an electric generating plant after it is built to improve its performance.
To furnish (e.g., a weapon) with new parts, equipment, or features not available at the time of manufacture.
upgrading of existing equipment or facilities for different or additional uses.
The renovation of a property to a higher standard. For example, an old brick building may be retrofitted to withstand an earthquake.
Modification of an existing structure to incorporate changes not available at time of original construction.
to return a facility or system to a complete and functional state by renovating or removing and/or adding parts; to update outmoded features to current standards of usability and code compliance. The term retrofitting is used in facilities management to describe the changing of a building's operational functionality; e.g., to retrofit is to go back and change, modify or upgrade to make a facility or system fit an operation. definition of retrofit defined definition of retrofitting defined definition of retrofitted defined
The act of removing water wasting fixtures and replacing them with water efficient fixtures. Approximately 20 years ago the CCSD implemented a retrofit program to replace plumbing fixtures in existing residences and businesses with water-conserving fixtures such as showerheads and toilets upon change of use or ownership. All new construction is required to meet the State of California and CCSD standards of retrofit. T All new construction must offset its proposed waer needs through retrofit of existing services. The retrofit requirement is based upon a combination of the square footage of the lot being built upon and the number of bathrooms being built.
Field upgrade that may be mandatory or selective. Mandatory retrofit means all field units must be upgraded to ensure reliable operation. Selective retrofit means that certain field units must be upgraded depending on the operating parameters.
An engine "retrofit" includes (but is not limited to) any of the following activities: Addition of new/better pollution control aftertreatment equipment to certified engines. Upgrading a certified engine to a cleaner certified configuration. Upgrading an uncertified engine to a cleaner "certified-like" configuration. Conversion of any engine to a cleaner fuel. Early replacement of older engines with newer (presumably cleaner) engines (in lieu of regular expected rebuilding). Use of cleaner fuel and/or emissions reducing fuel additive (without engine conversion).
An item that replaces components originally installed on equipment; a modification to in-service equipment.
The placing of new roof or wall systems over deteriorated roofs or obsolete roof and walls.
upgrading, replacing, extending an existing wiring systems in a building, or adding a new system to an existing building to comply with a current code or standard (e.g. fire code).
Replacement of one or more components of an existing system.
Renovation of an existing space, building, or system, usually to update outmoded features to current standards of usability and code compliance.
To change a vehicle or engine after its original purchase, usually by adding equipment such as conversion systems.
A return to something that is complete and functional; to remove and/or add parts. The term retrofitting is used in facilities management to describe the changing of a building's operational functionality. To retrofit is to act to change, modify or upgrade a function.
Refers to upgrading a fixture, room, building, etc., by installing new parts or equipment.
The modification of stormwater management systems through the construction and/or enhancement of wet ponds, wetland plantings, or other BMPs designed to improve water quality
Refers to the changing over of something existing. We use it when talking about changing over existing sprinkler systems to Drip.
To modify an existing system to bring it up to current standards.
The process of modifying a building's structure.
Retrofitting refers to the addition of new technology or features to older systems. An example of this is car customizing, where older vehicles are fitted with new technologies; power windows, cruise control, remote keyless systems, electric fuel pumps, etc. Particularly popular amongst auto enthusiasts is the process of correctly retrofitting OEM HID projectors into their outdated factory or aftermarket headlamps.
