Using a Performance Based approach does not preclude the use of prescriptive specifications. Although the benefits of the adopting of a PBBD approach are significant, it is recognized that employing a performance-based approach at any stage in the building process is more complex and expensive than using the simpler prescriptive route.
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 ...
[8] [24] The performance path allows for some more flexibility, when compared to prescriptive codes. [ 8 ] [ 24 ] The performance path achieves this by creating space for building design-solutions that provide trade-offs between energy-intensive systems in order to meet both the energy performance goal and optimize cost-effective measures for a ...
A functional specification is the more technical response to a matching requirements document, e.g. the Product Requirements Document "PRD" [citation needed]. Thus it picks up the results of the requirements analysis stage. On more complex systems multiple levels of functional specifications will typically nest to each other, e.g. on the system ...
A design specification (or product design specification) is a document which details exactly what criteria a product or a process should comply with. [1] If the product or its design are being created on behalf of a customer , the specification should reflect the requirements of the customer or client. [ 2 ]
Historically, most classes of technical documentation lacked universal conformity for format, content and structure. Standards are being developed to redress this through bodies such as the International Organization for Standardization(ISO), which has published standards relating to rules for preparation of user guides, manuals, product specifications, etc. for technical product documentation.
Concerning the water issue, the code requires a 20% reduction of indoor water use and it uses both a prescriptive and performance method. The prescriptive method provides some technical features that have to be followed: Showerheads ≤ 2.0 gpm (gallons per minute) @ 80 psi; Lavatory faucets ≤ 1.5 gpm @ 60 psi; Kitchen faucets ≤ 1.8 gpm ...
MIL-PRF-38535 [1] is a United States military specification that establishes the general performance and verification requirements of single die integrated circuit device type electronics. It is a performance-based specification document defining the general requirements, as well as the quality assurance and reliability requirements, for the ...
