How Municipalities Can Enable Net-Zero Construction
(A feasibility study in 4 cities over 8 sites, funded by FCM/GMF)

June,4 2019

 Click here for webinar recordings and slide decks

This webinar features lessons from the trenches of real projects. Four cities partnered with FCM/GMF to assess 8 project sites for technical feasibility (how to build net-zero neighbourhoods in 8 cases), financial feasibility (ie: how to fund it), and process feasibility (ie: how to get a permit). The participating cities all hosted mock-trial approvals processes and reported all the lessons learned. This webinar will cover the outcomes. (Find the report here.)

Some key things that you’ll hear more about in this webinar:

  • Technologies that enabled Net-Zero neighbourhood design in each of the 8 case studies;
  • Policies that work for enabling solar and district energy;
  • Incentives that are self-funding, which municipalities can actually afford, and which are actually helpful to builders.
  • Template legislation enabling net-zero energy systems and incentives which municipalities can adapt and adopt right now – ready for implementation.

High Performance Walls for Net Zero/Ready Homes Series

April, 2019 

Click here for webinar recordings and slide decks

There’s a need for changes in wall design, detailing, and construction to move towards more highly insulated assemblies required to reach Net Zero and Net Zero Ready levels of performance. Exterior wall systems are an important consideration that determine much of the cost and constructability of a home. Details left for consideration on-site can lead to delays, costs, and deficiencies.

Natural Resources Canada (NRCan) is using learnings from its Local Energy Efficiency Partnerships (LEEP) Initiative in British Columbia to establish some common wall assembly designs and details that builders, designers, and trades across Canada can use or modify for Net Zero and Net Zero Ready Homes.

Are you Still Air Sealing Your Homes From the INTERIOR?

September, 27 2018  

Click here for webinar recording and slide deck

An exceptional level of airtightness is a critical first step towards achieving net zero ready performance and ensuring long term performance and durability of the building envelope.  Simply adding more insulation to meet new stringent energy efficiency Codes without controlling air leakage could lead to unintended consequences and premature building enclosure failures.  

This webinar will cover the simple details of Owens Corning’s innovative CodeBord exterior air barrier system that helps builders achieve exceptional levels of airtightness (below 1.5 ACH at the framing stage) and provide maximum occupant comfort.

Jennifer Weatherston from Reid’s Heritage Homes will share her teams experience and journey in implementing the CodeBord exterior air barrier system in their construction.  Jennifer will outline the advantages and provide key take-aways required to successfully move the air barrier to the exterior.

The CodeBord exterior air barrier system provides:
•    Exceptional levels of airtightness (less than 1.5 ACH at the framing stage)
•    Reduced construction costs
•    Reduced call backs
•    Opportunity for replacing interior polyethylene vapor barrier with vapor barrier paint
•    Opportunity to achieve the required heat, air and moisture control layers all from the exterior with one product!

The Impact of Fenestration on the Building Envelope: A Window of Opportunity

January, 18 2017

 Click here for webinar recording and slide deck

Increasing energy performance requirements in codes means rethinking how we build envelopes. Examining the entire wall assembly and optimizing the window specifications may prove to be the best opportunity for builders to cost effectively improve the overall performance of their homes.

This webinar will show you how

  • selecting the right glass package can influence your cooling loads,
  • the window-to-wall ratio impacts the overall effective R value of your wall, and
  • putting in better windows reduces initial costs and operational costs.

A more holistic approach to the building envelope may be the most cost effective way to deliver high performance homes as well as increase comfort for the occupants. Understanding the energy performance numbers for windows and how they influence the size of the mechanical systems is key to providing cost efficient solutions to improving the building envelope.

 Click here for webinar recording and slide deck

This presentation provides the results of the NRCan ecoEII Owens Corning Net Zero Energy Communities initiative. The project aimed to demonstrate the feasibility of building Net Zero Energy housing communities - addressing the challenges specific to production housing, and to act as a platform for the broader adoption of Net Zero Energy homes across Canada. Owens Coming Canada recruited 5 builders across Canada to participate:

  • Mattamy Calgary Ltd. (Alberta)
  • Reid's Heritage Homes (Ontario)
  • Minto Communities (Ontario)
  • Construction Voyer (Quebec)
  • Provident Developments Inc. (Nova Scotia)

All of the teams held public opening events, and construction of all 26 homes is complete. Check out the project videos here. More information can be found on the project website here.

Andy Goyda, Market Development Manager at Owens Corning Canada, provides an overview of the project results, and representatives from each builder present an overview of their Net Zero Energy/Ready homes.

The F280-12 Standard: Right-Sized HVAC for Net Zero and Net Zero Ready Homes

May, 26 2016

 Click here for webinar recording and slide deck.

Are you a planning on building a Net Zero or Net Zero Ready Home? Using right-sized HVAC equipment and ductwork will prevent on-off short-cycling, prolong equipment life, and increase operational efficiencies – not to mention improve occupant comfort. Smaller equipment and ductwork can also allow for greater design flexibility, offering more living space.

Andy Oding, Senior Building Science Associate at Building Knowledge Canada, addresses the key points of this standard, including:

  • Why it’s important that residential space heating/cooling systems have the appropriate output capacity – especially in low load homes such as Net Zero and Net Zero Ready Homes.
  • How to calculate the heat loss/gain of homes for selecting the appropriate output capacity of a space heating/cooling appliance.

Michelle Côté, Director of Business Development at Dettson Industries provides examples of their sustainable HVAC solutions designed to maximize residential comfort.

LEEP PV Webinar Series

January/February 2016 

Click here for Webinar Recordings and Slide Deck

During the Spring/Summer of 2015, thirteen (13) leading Lower Mainland BC builders participated in Natural Resources Canada’s (NRCan’s) Local Energy Efficiency Partnership (LEEP) initiative. It was brought to the region through the support of the BC Homeowner Protection Office, BC Hydro, Fortis BC, the City of Vancouver, and the City of New Westminster.

Builders use LEEP to reduce their time and risk in finding and trying innovations that could help them build higher performance homes better, faster and more affordably, reduce technical barriers, and improve supply chains.  

During the LEEP workshops in BC’s Lower Mainland, builders requested 3 presentations on Photovoltaic (PV) systems. CHBA hosted these presentations from experts on PV best practices and costing, which were reviewed by the BC builders, as part of the Net Zero webinar series.
