[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 ...
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.
Prescriptive specifications define the requirements using generic or proprietary descriptions of what is required, whereas performance specifications focus on the outcomes rather than the characteristics of the components. Specifications are an integral part of Building Information Modeling and cover the non-geometric requirements.
"50 Divisions" is the most widely used standard for organizing specifications and other written information for commercial and institutional building projects in the United States and Canada. [5] Standardizing the presentation of such information improves communication among all parties.
Building performance is measured early too, so that trade offs between budget, schedule, functionality and usability can inform specification and continuous refinement of the design. Architects engaged in this dynamic process understand and keep up to date with the potential of contemporary technology [ 19 ] and materials available to building ...
ANSI/ASHRAE/IES Standard 90.1: Energy Standard for Buildings Except Low-Rise Residential Buildings is an American National Standards Institute (ANSI) standard published by ASHRAE and jointly sponsored by the Illuminating Engineering Society (IES) that provides minimum requirements for energy efficient designs for buildings except for low-rise residential buildings (i.e. single-family homes ...
Construction design specifications are referenced in US government procurement rules, where there is a requirement that an architect-engineer should specify using "the maximum practicable amount of recovered materials consistent with the performance requirements, availability, price reasonableness, and cost-effectiveness" in a construction design specification.
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 ...
