W09 – The Future of High Performance: Energy & Objective Based Codes
[Building Performance, Green]
[ BOMI 1.5 CPD • 1.5 AAA Structured LHs • 1.5 HSW-Building Code Hours IDCEC Approved ]
Building standards and codes are rapidly moving toward performance based compliance models. This is challenging to both industry and government. Simplistic but easily applicable and transparent “do this, don't do that” prescriptive codes have the benefit of providing consistent and accessible information to communicate minimum standards. However, general acceptance of prescriptive minimums often prove problematic as the minimum becomes standard or possibly even considered best practice. This may lead to stagnation in expectation and prevent innovation in the design and construction industry. Performance based codes conversely evaluate non-standard solution sets against minimum design objectives to determine compliance. These models are certainly more flexible, but carry with them a higher standard of proof, and may strain consulting, contracting and owner decision making processes and coordination.
The rapid move toward performance based codes is nowhere more observable than the recently adopted energy codes. As whole-building energy efficiency standards with purposely designed performance path options of compliance, the energy codes provide insight into future code development and how performance evaluation may be used in both energy and life safety codes.
Together, ABC 9.36 and the National Energy Code of Canada for Buildings (NECB) provide examples of the significant opportunity for consulting to be more flexible in project choices, and more responsive to owner budgets in the design process. Contractors likewise are affected by performance-based codes, as contract administration, tendering, and procurement are all impacted. Lastly, owners must become aware of the decisions making processes, specific expertise requirements, and scheduling practices and budget shifts necessary to economically benefit most from performance based codes.
In order to explore these impacts adequately, this presentation will review the impetus and philosophy of performance based codes, and explore the relationship to other design problems such as analogues. Primarily using the energy codes for illustrative purposes, the speaker will demonstrate how performance options can affect project schedules, delivery methodology, and budgets for construction projects. Finally, the presenter will explore where code documents are headed, and how industry may be impacted in the future with a focus on permitting and approvals.
