Energy Storage – A Homebuilder’s Introduction (June 22, 2016)

Click here for webinar recording and slide deck

Energy storage is a natural step in the evolution of sustainable and resilient home building. This cutting edge technology increases the amount of solar energy used directly in the home. It also provides a reliable, quiet and safe source of backup power. And for builders, it’s a key differentiator that will change the way people look at your next development, and your business as a whole.
​

On this webinar you’ll receive an overview of this state-of-the-art technology, including how energy storage has been geared to residential applications, and key considerations for including it in your current and future projects.
​

This webinar combines an introduction to energy storage technology with basic guidelines on how to plan for and implement it. Key take-aways include:

• Energy Storage Solutions & Configurations
• Criteria for Selection
• What you need to know in advance
• Builder case studies

Presenter: Anil Parekh, P.Eng. - Senior Researcher with Natural Resources Canada

Anil has been working in the housing energy efficiency field for over twenty-five years focusing on building envelope technologies, energy analysis and performance evaluations.  He is also Technical Advisor for the leading-edge standards such as R-2000, ENERGY STAR and EnerGuide Rating System.

HOT2000 is an energy simulation and design tool for low-rise residential buildings. It supports Natural Resources Canada’s EnerGuide Rating System, ENERGY STAR for New Homes and R-2000 energy efficiency residential programs. In 2015, updates to the rating system resulted in a new version of HOT2000 and new complementary report generation software. Anil's presentation will focus on modelling renewable energy in HOT2000 to determine the energy "budget" for a home.

Presenter: Sal Ciarlo, P.Eng. - Technical Services & Codes and Standards Manager at Owens Corning Canada

Sal is responsible for the design, certification and commercialization of complete building enclosure systems for the commercial, industrial and residential building construction markets. As a civil engineer with more than 25 years of building science experience, he specialises in high performance and net zero building envelope designs, acoustic and fire separation systems and solutions.  Sal is very active on Provincial and National Code committees helping to develop energy codes and standards.  He has presented educational seminars to architects, engineering professionals and builders across the country, focusing on next generation building envelope solutions and designs, net zero envelopes, air barrier systems, noise control and fire protection systems.

The Owens Corning effective thermal resistance calculator uses the calculation methodology, material values and framing factors listed in appendix A-9.36.2.4.1 of the National Building Code of Canada. Wood structural members are of the spruce-pine-fir type with a thermal resistance of RSI 0.0085/mm of thickness. Steel stud members are available as an option for walls above grade assemblies only with a thermal resistance of RSI 0.0000161/mm. The user can view the individual material thermal resistance values used in the calculation for the design assembly chosen by clicking on the “Download Results” icon. Assembly details are grouped by Continuous and Non-Continuous layers.

Presenter: Robert Jonkman, P.Eng. - Director Codes and Standards - Structural Engineering at Canadian Wood Council

Rob joined the Canadian Wood Council’s Codes and Standards division in 2005, progressing to “Director, Codes and Standards - Structural Engineering” in 2014. Concentrating on structural engineering, building science, and energy issues, Rob is responsible for the CWC’s Publication and Software business centre, participates on the Technical Research Committee and the Net Zero Energy Housing council of the Canadian Home Builder’s Association, participates on national building code committees (Structural and Energy) and is the Secretary/Associate for the Technical Committee on the “Engineering Design in Wood” (CSA O86) Standard.

The Canadian Wood Council’s interactive Wall Thermal Design (WTD) calculator is a free tool to help designers comply to the new energy requirements. The calculator enables designers to explore options, compare features, and determine a suitable wall assembly that can perform across a range of Canadian climates. This free online tool provides effective R-values for wall assemblies and includes a durability assessment that considers computer modeling and field experience.

Presenter: Patrick Roppel, P.Eng., M.A.Sc. - Principal, Building Science Specialist at Morrison Hershfield

Patrick manages the Building Performance Analysis Department at Morrison Hershfield.  Patrick is a Building Science Specialist with a technical focus on evaluating the performance of the building envelope through testing, monitoring, and numerical simulations. Patrick manages and provides technical oversight on new construction and retrofit projects, investigation and assessment of existing buildings, and building science research.

The Building Envelope Thermal Bridging Guide was prepared by Morrison Hershfield Ltd. incollaboration with many stakeholders and industry partners. This publication is provided to inform the practice of applying the Building Envelope Thermal Analysis (BETA) methodology for determining the effective thermal performance of building envelope assembly and interface details, as well as to guide BETA’s application in overall building design.

The Impact of Fenestration on the Building Envelope: A Window of Opportunity (Jan 18, 2017)

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.

5 Net Zero Energy Builder Success Stories (Jun 9, 2016)

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)

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.
