Editor's Notes
- Registered Professional Does not include Landscape architect Certified energy advisor Etc.
- Builds on the greening of the BC Building Code (2008) when ASHRAE 90.1-2004 was brought in Relies on Registered Professional declaration of compliance via Letters of Assurance Is CHALLENGING from a design perspective Multi-discipline standard Many pathways to compliance Requires a high level of coordination from the initial design stage to be effective Is relatively SIMPLE from regulator’s standpoint Able to accept pre-formatted declarations from qualified registered professionals Challenge is now to ensure that RP’s have coordinated sufficiently and to gain comfort that the building will likely achieve the EE aimed for Done through additional submittals to AHJ Also known as Verification Documentation
- Both COV and CNV have established design verification documentation Have slightly differing goals as to the intent of the submissions CNV Intent is solely to provide AHJ with comfort that design has been coordinated effectively Requires joint statement of a single pathway to compliance by design team Clearly assigns responsibility for meeting each portion of Standard COV Goes beyond coordination verification to data-gathering Includes declarations of Effective R-value Energy use intensities Rezoning condition compliance District energy compliance Used effectively, one of these design verification checklists can give an AHJ (Building Inspector or plan checker) Quick and easy high-level verification of design intent The confidence to review a highly technical requirement with a registered professional
- Mid-stream amendment to the 2012 BC Building Code Developed by a sub-committee of the Canadian Commission of Building and Fire Codes (NRC) Initially a mid-stream amendment to the NBC BC is the first province to adopt the new Section at the provincial level At about 110 pages, is the largest single mid-stream amendment to a building code in recent history, possibly ever There are multiple pathways to compliance in the new Section Part 9 has traditionally be prescriptive Designed as an ‘instruction manual’ such that someone with little training can build This is the first time multiple ‘options’ exist to meet Part 9 requirements This is a paradigm shift A completely new philosophy to Code compliance for Part 9 buildings
- Treats the building as a system Recognizes (and forces designers/builders to recognize) that the building works as a system Allows trade-off between building components Enables performance-based design Formalizes the EnerGuide Rating System as a compliance path, much more visible than what is currently provided in BCBC Introduces NECB as a compliance option for all Part 9 buildings Removes barriers for new technologies Current Code focuses on in-cavity insulation only Effective R-value approach broadens the definition of ‘thermal insulating materials’ Allows more innovative design options, such as Passive House
- Additional attention to detail at design stage What pathways of compliance are available for your project? More information to be required on design drawings Possible expansion of design team Certified Energy Advisor may become more commonplace Whole new Code to use National Energy Code for Buildings is ONLY pathway to compliance for some buildings Small factories Woodworking shops Automotive shops Drycleaners, etc. A new normal Air-sealing Hybrid insulation systems Treating the building as a system Heating systems type and location (to minimize penetrations) Ventilation detailing Trade-offs between building components Has the opportunity to be a paradigm shift in how buildings are built In an industry that hasn’t experienced change at this scale for over a quarter-century
- Plan Check Additional review elements Verify chosen pathway to compliance Tailor review to suit pathway (prescriptive or performance) Prescriptive: one extra duty would be to calculate effective r-value for the proposed assembly Performance: additional training and/or in-house resources to verify compliance Confirm that AHJ has sufficient information to be able to issue permit and conduct inspections later on Permits for heating systems? House is a system Other requirements can change, based on ventilation (if HRV is provided) Most AHJ’s do not provide Permits for heating systems; however, now that requirements are interlinked, do we need to start Permitting heating systems? Inspections Inconsistent on-site requirements Until now, wall assemblies have been fairly standard (looking for typical insulation being provided) With multiple pathways to compliance, Building Officials will have to review detailed Permit requirements prior to each inspection It may be OK that a roof or wall assembly has very little insulation A new normal City staff will need to begin to look at buildings as a system, just as the Code does Increased collaboration between Inspections disciplines The Building Official will need to speak to the Plumbing Inspector and Plan Checker Possibly increased processing time (both plan check and inspections) as industry and AHJ processes adjust
