Mechanical ventilation equipment is a key component of your building and has a great influence on the comfort and health of the occupants. Gord Cooke from Building Knowledge Canada will share his thoughts and advice based on his extensive experience. Loïc Arès from Venmar will provide useful information to guide the builders and energy advisors through the different options available. Doug Tarry from Doug Tarry Homes will provide input about the use of energy recovery ventilators from a builders’ perspective, based on his experience and the feedback from home owners.

This webinar will provide answers to some common questions about ventilation and also provide you with a better understanding of heat and energy recovery ventilators:

 

  • The science and history on why ventilation is important
  • Why “leaky” houses have worse air quality than “tight” houses
  • How to choose the right unit (HRV vs ERV, airflow, efficiency)
  • The different installation options and their advantages
  • Canadian testing requirements that ensure performance in our climate
  • What home owners need to know about ventilation

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 (Jan 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.

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 (Jan/Feb 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.
