A building code that specifies construction requirements according to particular materials and construction methods, rather than to performance criteria.
There are often additional codes or sections of the same building code that have more specific requirements that apply to dwellings or places of business and special construction objects such as canopies, signs, pedestrian walkways, parking lots, and radio and television antennas. The main purpose of building codes are to protect public health, safety and general welfare as they relate to the construction and occupancy of buildings and structures. The building code becomes law of a particular jurisdiction when formally enacted by the appropriate governmental or private authority. 1. Prescriptive Path. In the prescriptive path, the Code provides conservative method of construction to ensure the building will resist wind and earthquake loads using braced wall panels, continuous sheathing and tie-down anchors. 1. Prescriptive PathIn the prescriptive path, the Code provides conservative method of construction to ensure the building will resist wind and earthquake loads using braced wall panels, continuous sheathing and tie-down anchors. Instead, it is filled with flammable polyurethane foam. A building code, or building control, is a set of rules that specify the minimum standards for constructed objects such as buildings and nonbuilding structures. The main purpose of building codes are to protect public health, safety and general welfare as they relate to the construction and occupancy of buildings and structures. The building code becomes law of a particular jurisdiction when formally enacted by the appropriate governmental or private authority. Building Codes set out minimum construction standards. The BC Building Code is based on the model National Building Code of Canada and is adopted by the Province of B.C. with some modifications. All construction in B.C. must conform to requirements in the BC Building Code, except for the City of Vancouver.  Prescriptive vs. Performance Building Energy Codes. Most building energy codes today offer two paths for compliance: Prescriptive or Performance. In this post, we’ll discuss the two different paths and why many projects follow the Prescriptive path even though the Performance path is probably more cost-effective. Provided the mandatory requirements are met, the rest of the code can be met in one of two ways. The project team can follow prescriptive requirements, building each component to a certain level of performance (some of the 2012 IECC prescriptive requirements are shown below). 14 Cascadia Green Building Council OUTCOME-BASED CODES An emerging alternative to prescriptive and performance-based energy codes is outcome-based codes. This framework considers the whole building’s energy use over a consecutive 12-month period including end uses that are currently unregulated.  Typical Code Structure. A prescriptive code requires that each component is built to a certain standard, e.g. Wall R-value at least 20. A performance code requires that the building as a whole performs to a certain standard, e.g. uses less energy than the same building built to prescriptive code. Provided the mandatory requirements are met, the rest of the code can be met in one of two ways. The project team can follow prescriptive requirements, building each component to a certain level of performance (some of the 2012 IECC prescriptive requirements are shown below). A prescriptive code, like the Illinois Plumbing Code, furnishes both specific requirements and the prescribed methods for reaching them. A performance-based code is like having an address to which you are supposed to drive and a map of that city with the location marked. A prescriptive code is like having the address, a map of the entire area marked with your route and clearly written turn-by-turn directions. more TeachMeFinance.com-explain prescriptive code. prescriptive code -- a building code that specifies construction requirements according to particular materials and construction methods, rather than to performance criteria.
