2 Agenda Energy Step Code & City Policy Direction Background and implementation framework for Part 9 and Part 3 Buildings Industry feedback and recommendations from Fall 2017 to support Energy Step Code adoption Update on City s Passive Design Exclusion policy for single-detached zones Working with an Energy Advisor & BC Energy Compliance Report Role of an Energy Advisor and benefits for builders, architects and designers Importance of energy modeling and integration with design/construction processes Introduction to new BC Energy Compliance Report for Part 9 Buildings Feedback on Implementation Framework Facilitated discussion on proposed implementation framework for Part 9 Buildings 2

3 National and Provincial Building Code Direction Pan Canadian Framework on Clean Growth and Climate Change Federal direction for the National Building Code is to adopt increasingly stringent, model building codes starting in 2020, with the goal that all provinces and territories adopt net zero energy ready building requirements by BC Climate Leadership Plan Intent is for phased updates to the BC Building Code so that all new buildings are net zero ready by 2032, using the Step Code as the framework for setting beyond Code requirements. Only three Building Code cycles away! 3

9 Energy Step Code Overview Part 3 Performance Path for New Construction Review Proposed Framework for Part 3 Buildings at our next Builder & Designer Breakfast in May

10 New Technical Resources from BC Housing Integral Group Consulting to present on new Design Guide at our next Builder & Designer Breakfast, May 2018

11 Preparing our Local Market PREPARING OUR LOCAL MARKET FOR THE ENERGY STEP CODE Launched in 2015, High Performance New Home program to support homebuilders, architects and designers with strategies designed to improve industry readiness for transition to a performance based approach required by the Step Code.

12 Current Program Incentives EnerGuide Rating System Energy modeling, plan evaluation report with upgrade options and home energy labelling. Blower Door Testing Diagnostic testing at mid-stage construction to improve air tightness of the home Energy Coaching Technical guidance on building envelope or mechanical upgrade options.

13 High Performance New Home Program Projects High Performance New Home Program is actively involved in over thirty (30) new construction projects with encouraging results. GJ Rating Average completed project is 15% better than code built reference house Air Tightness Average air tightness is Pa which is 45% better than industry average Green Building Four ENERGY STAR rated homes. All completed projects EnerGuide rated with voluntary disclosure on RateOurHome.ca Training - Nine local builders / trades completed 5- day Passive House Construction Course at BCIT (October 2017).

17 Training & Professional Development Training Energy Save New West is providing training and incentives to help builders, designers and architects access professional development resources that support green building practices. Builder & Designer Breakfast Series (6 to date) Local Energy Efficiency Partnership Passive House Canada (Building Envelopes and Tradesperson courses)

18 Awareness Building Awareness Building Energy Save New West has been developing marketing and communication tools designed to raise awareness of the opportunities and benefits of designing and constructing high performance homes.

19 Supportive Policies Passive Design Exclusions PRINCIPAL HOME LANEWAY HOME 6,000+ single-detached lots in New Westminster 19

20 Allowance for Thicker Insulated Walls Split Insulated Assembly Minimum R22 Effective and higher

21 Passive Design Exclusions Allowable Density Increase Performance Requirement Increase in FSR (Density) Step Code Level 3 Increase by 0.10 Step Code Level 4 Increase by 0.30 Step Code Level 5 Increase by 0.55

22 Allowance for Deeper Insulated Roofs and Foundations For Step Code Level 5 and Passive House projects, City has discretion to relax building height by up to 4 feet.

23 New Resources from BC Housing Updated Guide for R22+ Wall Assemblies

24 Implementation Framework MUNICIPAL CONTEXT To date, 17 municipalities have submitted a notification form to the Province of BC indicating that they are consulting with local building industry on the Step Code. 24

25 Implementation Framework LEADING BY EXAMPLE In Fall 2017, City of North Vancouver updated it s base Bylaw requirements to reference the BC Energy Step Code on new construction projects. More recently, City of North Vancouver, District of North Vancouver and District of West Vancouver have agreed to take a consolidated approach to aligning Step Code performance requirements and implementation timing a North Shore approach! 25

26 Performance Path Transition WORKING WITH AN ENERGY ADVISOR BC Housing s 2017 Local Government Survey estimated that less than 10% of builders are working with an Energy Advisor on projects. New Westminster Current New Westminster Summer % 26

27 Implementation Framework STAGED IMPLEMENTATION City of New Westminster is proposing a staged approach for implementing minimum requirements on the BC Energy Step for Part 9 buildings (starting in July 2018). Part 9 Residential July 2018 June 2019 January 2022 Single Detached House Step 1 Step 3 Step 4 Laneway / Carriage Home Step 1 Step 2 Step 3 Duplex, Triplex or Quadplex Step 1 Step 3 Step 4 Townhomes, Stacked Townhomes Step 1 Step 3 Step 4 Industry Training TBD Incentives for Energy Modeling TBD 27

28 Fall 2017 Builder Breakfast Feedback COST MANAGEMENT Enable builders to minimize costs while supporting industry education and consumer awareness on value of higher performance, including non-energy benefits. o o o Need a comparison of homes that look the same, but a highperformance home is more than look, its about higher quality. Incentives for floor space ratio and permit fee reduction could help minimize incremental costs. Consumer education on benefits of high performance (e.g. air quality, comfort, health) and payback period is what resonates. 28

29 Fall 2017 Builder Breakfast Feedback REGULATORY COMPLIANCE Implement and enforce new performance standards consistently, while ensuring that potential time delays for regulatory procedures are minimized. o o o Implementation over 5-years starting in 2018 for Step 1 and then onwards is feasible. Industry needs time for learning, including trial and error, and trial and success. Require compliance forms completed by the Energy Advisor (like Letters of Assurance) as part of the permit process This tool would ensure contractors were required to meet the standards. Standardizing processes across municipalities, and ensure that inspectors and plan checkers are trained so that everyone is on the same page. 29

30 Fall 2017 Builder Breakfast Feedback SUPPORT & TRAINING Municipalities, BC Housing, Province of BC should continue to support industry workshops, technical courses, information sharing and education for industry. o o o Mandatory training could be considered for builders and building officials. Industry needs better understanding of what energy modeling does, its benefits, what to look out for, as well as Energy Advisor advice on what to focus on for best effect. Training is required for designers, tradespeople and inspectors so that everyone is informed, and all working towards the same goal. 30

31 Workshop Questions Table Discussion Proposed Step Code Implementation Framework for Part 9 Buildings 1. Are we on right track with respect to Step Code implementation timing (e.g. Summer 2018 for Level 1, Summer 2019 for Level 3)? 2. Are you ready to work with an Energy Advisor on your next project? Will you be taking advantage of the City s incentive program? 3. What other support do you need to help your firm transition to the performance path approach? 31

32 Next Steps To Summer 2018 STAKEHOLDER ENGAGEMENT AND TRAINING Developer / Builder / Designer focused Part 3 buildings Building & Designer Breakfast #7 (May 2018) UDI Liaison Committee Step Code workshop for Part 3 buildings (Spring 2018). Including Step Code requirements for new buildings inside and outside low carbon zones. City staff focused All building types Development Services workshop on Step Code compliance process (Spring 2018) Review of current permitting / review processes to support Step Code implementation (Spring 2018) Training & Incentives Subsidies for next Passive House Tradesperson course at BCIT (April 16 th to 20 th, 2018) Combined City and BC Hydro incentive funding on Energy Advisor services through our High Performance New Home Program (2018 and 2019). 32
