BC Energy Compliance Reports – Performance Paths for Part 9 Buildings

The BC Energy Compliance Reports provide a standardized report template for Part 9 buildings complying with Subsection 9.36.5. or 9.36.6. of the BC Building Code. Technical Bulletin B18-03 (PDF), published by the Building and Safety Standards Branch, provides a plain-language description of the reports and how they can be used.

There are currently two versions of the reporting packages: the BC Building Code 2018 version and the BC Building Code 2012 version. Each version has four parts:

  1. Pre-Construction Report
    • For builders to submit to the Authority Having Jurisdiction (AHJ) when applying for a building permit, to demonstrate that the designed building complies with the BC Building Code’s energy-efficiency requirements
  2. As-Built Report
    • For builders to submit to the AHJ following construction and prior to final inspection or occupancy, to verify airtightness and energy-performance requirements
  3. Compliance Report Instruction Manual for Energy Advisors
    • Provides general guidelines for using the BC Energy Compliance Report
    • Includes a table of instructions for completing the BC Energy Compliance Report
    • Outlines how to use H0T2000 to calculate the BC Energy Step Code metrics
  4. Compliance Report Calculator
    • To be used with the Compliance Report Instruction Manual to create the reports

Other Technical Bulletins that may be useful for Energy Advisors and others using the reports include:

BC Building Code 2018 Version

This version of the reports (and associated tools) is for projects complying with BC Building Code 2018. An update to the manual and the calculator to provide guidance for attached ground-oriented residential buildings that are not considered multi-unit residential buildings (MURBs) under the EnerGuide Rating System is expected in Spring 2019.

  1. Pre-Construction Report (PDF) (Note: the Calculator has a built-in report generator)
  2. As-Built Report (PDF) (Note: the Calculator has a built-in report generator)
  3. Compliance Report Instruction Manual for Energy Advisors (PDF, 1.7MB) – an updated version of the manual is expected in Spring 2019
  4. Compliance Report Calculator and Report Generator  (XLS) – an updated version of the calculator is expected in Spring 2019

Read notes below on using the Compliance Report Calculator and Report Generator.

BC Building Code 2012 Version

This version of the reports (and associated tools) is for projects complying with BC Building Code 2012.

  1. Pre-Construction Report (PDF)
  2. As-Built  Report (PDF)
  3. Compliance Report Instruction Manual for Energy Advisors (PDF, 1.2MB)
  4. Compliance Report Calculator Version (XLS)

BC Energy Compliance Report Training Webinar

This February 2018 recorded training session is based on the BC Building Code 2012 version of the reports. The training session:

  • Is designed for EnerGuide Rating System Energy Advisors and service organizations
  • Introduces the BC Energy Step Code, reviews the 2012 BC Energy Step Code Metrics, and introduces the BC Energy Compliance Report Instruction Manual and the Compliance Report Calculator

 

About the Part 9 Energy Compliance Reports

Information Required by the BC Building Code

Article 2.2.8.2. (Information Required on Drawings and Specifications) of Division C of the BC Building Code requires certain information to be provided on drawings or specifications to the Authority Having Jurisdiction. This includes:

a)  the effective thermal resistance values and respective areas of all opaque building envelope assemblies, including all above-ground and below-ground roof/ceiling, wall, and floor assemblies
b)  the overall thermal transmittance (U-value), solar heat gain coefficient and respective areas of all fenestration and door components
c)  the ratio of total vertical fenestration and door area to gross wall area
d)  the performance rating, energy source, and types of all equipment required for space-heating and -cooling and service water heating
e)  the design basis for the ventilation rates
f)  where a test is used to determine the airtightness of a house, the measured airtightness of the building envelope in air changes per hour
g)  any additional features used in the energy model calculations that account for a significant difference in house energy performance

The Part 9 reports offer a standard format for providing this information to an Authority Having Jurisdiction.

Different Versions of the Reports

Different versions of the reports align with different versions of the BC Building Code. Energy Advisors and energy modellers should use the version that corresponds to the version of the BC Building Code to which the building is constructed.

  • Projects being constructed to BC Building Code 2018 use the 2018 version of both reports (Pre-Construction and As-Built)
  • Projects being constructed to BC Building Code 2012 use the 2012 version of both reports (Pre-Construction and As-Built)

For a building permit application submitted on or after December 10, 2018 that used the 2012 version of the reports, before the 2018 version was available, the Energy Advisor or energy modeller will likely have to transfer data from the 2012 version of the reports to the 2018 version. Consult your Authority Having Jurisdiction on their procedures.

For more information about which version of the BC Building Code applies, visit the BC Building Codes 2018 webpage. You can also contact your local building official if you have questions.

The BC Building Code 2018 Version of the Reports

The BC Building Code 2018 version of the reports includes several updates. As explained in the Compliance Report Instruction Manual, features of the Microsoft Excel BC Energy Step Code Compliance Calculator and integrated Report Generator include:

  • A calculator tool to assist with the calculations for Section D and the additional metrics for Section F of the BC Energy Compliance Report. By entering data from the HOT2000 energy model, selecting the project’s Climate Zone, entering cooling system capacity, and the required ‘Step’, this tool calculates the Mechanical Energy Use Intensity (MEUI), ERS Rating % Lower Than EnerGuide Reference House, and Thermal Energy Demand Intensity (TEDI) for Section D, and Other Energy Modelling Metrics for Section F. The calculator also compares the calculated Step Code Metrics to the selected required Step and determines which metric the home passed and the overall result.
  • A Report Generator for the Pre-Construction and As-Built Compliance Reports. The calculated metrics do not have to be transferred to a separate document (such as a PDF version of the Compliance Report). Various other sections of the reports will also auto-populate to save the Energy Advisor time and reduce potential for data entry errors.

When using the Compliance Report Calculator and Report Generator:

  • Update your Microsoft Excel software to a recent version of the software. Legacy versions of Microsoft Excel may not be supported and could affect the functionality of the calculator.
  • When using the calculator, or doing manual calculations, ensure the HOT2000 file is set to metric units.
  • Keep the P-file (Pre-Construction) section of the calculator static when updating the As-Built report to keep a record of what had been submitted. In other words, do not update the Proposed House and Proposed Reference House entries in the P-file (Pre-Construction) section of the calculator when doing the As-Built and As-Built Reference House entries.
  • For a detailed description on how to calculate “% Building’s Conditioned Space Served by Space-Cooling Equipment” for determining the MEUI target see Appendix IX.
  • If you have questions about the functionality of the calculator, check the Compliance Report Instruction Manual for Energy Advisors and/or the instructions tabs in the Excel Compliance Calculator and Report Generator.
