New Source Performance Standards (NSPS) are pollution control standards issued by the United States Environmental Protection Agency (EPA). The term is used in the Clean Air Act Extension of 1970 (CAA) to refer to air pollution emission standards, and in the Clean Water Act (CWA) referring to standards for water pollution discharges of industrial wastewater to surface waters.
A minimum energy performance standard (MEPS) is a specification, containing a number of performance requirements for an energy-using device, that effectively limits the maximum amount of energy that may be consumed by a product in performing a specified task. An MEPS is usually made mandatory by a government's energy efficiency body.
Flawed performance standards or measures are attributed to the use of subjective criteria or ambiguous measures by raters during PAs. One cause of this issue is the difficulty in defining objective performance standards due to the complexity of job tasks or outcomes. [65]
Specifications can be either "performance-based", whereby the specifier restricts the text to stating the performance that must be achieved by the completed work, "prescriptive" where the specifier states the specific criteria such as fabrication standards applicable to the item, or "proprietary", whereby the specifier indicates specific ...
The primary types of technical standards are: A standard specification is an explicit set of requirements for an item, material, component, system or service. It is often used to formalize the technical aspects of a procurement agreement or contract. [2]
The question of whether performance differences are quality differences may depend on circumstantial preferences-but preferences based on functional requirements, not taste. Some performance standards are based on subjective preferences, but the preferences are so universal that they have the force of an objective standard. [1]
Operational standards often include pre-defined lists of standard performance measures. For example, EN 15341 [9] identifies 71 performance indicators, whereof 21 are technical indicators, or those in a US Federal Government directive from 1999—National Partnership for Reinventing Government, USA; Balancing Measures: Best Practices in Performance Management, August 1999.
Most recently the clearest definition of performance based building approach was explained in 1982 by the CIB W60 Commission in the report n.64, where Gibson stated that "first and foremost, the performance approach is [...] the practice of thinking and working in terms of ends rather than means.[ …] It is concerned with what a building or ...
