1 Plan /Submission Requirements As a result of the Code changes additional information will be required at the building permit application stage to ensure compliance with new 2012 BCBC requirements. This information should be provided on the building permit drawings. You may wish to use the 9.36 Energy Efficiency Design Worksheet. The following must be specified on the submitted plans: The plans are in compliance with the 2012 British Columbia Building Code; The plans are designed for Climatic Zone 5, 6 or 7A (dependent on location in the RDOS) The compliance path: o Prescriptive o Prescriptive with Trade-offs including calculations; or o Performance including energy modelling calculations The proposed values for specific construction elements as follows: Zone 5 Zone 6 Zone 7A Without With Without With Without With Ceilings below attics Cathedral ceilings & flat roofs Exterior Walls (including rim joists) Garage/dwelling wall assemblies Floors over unheated space Foundation walls Floors on ground (slab on grade) Heated floors Unheated floors (above frost line) Max U-Value Windows & Doors Skylights Identification and calculations for any trade-off proposals; Identification of air barrier location; Location and specifications for any rigid insulation in assemblies; details at plumbing and ductwork adjacent to insulated assemblies; In order to facilitate review of building permit applications, the submitted drawings must accurately indicate the proposed construction. Cross sections and details must clearly show enough information to show compliance with the 2012 BCBC. Ppage1Page
