Tools to Help Design Building Envelopes for Net Zero Homes (Feb 16, 2017)
Click here for webinar recording and slide decks
Join us for
this webinar to learn about some of the tools that Energy Advisors and
Builders are using to help design Building Envelopes for Net Zero Homes.
Each presenter will provide an introduction to their tool, highlighting
the key functionality and outputs. You will learn where to access the
tools and who to contact for more information. After the presentations,
you will have the opportunity to ask questions to the panel.
Moderator: Derek Satnik, P.Eng., LEED(r) AP - VP of Technology at s2e Technologies
Derek
Satnik is a familiar face in CHBA and related discussions on sustainable
housing. With nearly 40 million square feet of improved buildings on
his resume and over 85,000 kW of renewable energy projects, Derek has
made significant contributions to most of Canada’s leading green
building programs including ENERGY STAR, BUILT GREEN, LEED, Net-Zero,
and related codes and legislation.
Now as VP
of Technology at s2e Technologies, Derek leads s2e’s Smart Communities
business, working with leading developers, technology suppliers and
community designers on some of the most sustainable and technologically
advanced communities in the world.
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.
