13th CCBST conference - Winnipeg 2011 |
|
The 13th Canadian Conference on Building Science and Technology Winnipeg, Manitoba May 10 - 13, 2011 www.fortgarryhotel.com The 13th conference will emphasize new innovations and ideas which are still under development in the building science industry and illustrate how our past techniques and technology have helped to bring us to this point. We, as an industry, are being pushed to design buildings which meet higher standards. Whether the push is to design highly efficient buildings, use greener technologies, or come up with new sustainable solutions, we would like to address the question of how this has or will affect research and current and future building practices. We have currently opened up the opportunity to sponsor / exhibit for the upcoming conference.

Date: Wednesday May 26, 2010 Time: 3:00 - 5:00 pm @ The Viscount Gort Hotel - 1670 Portage Avenue Building Science Truths, Half Truths, Myths, Misunderstandings, Hype & Lies
Round 2
| Building Design Professionals are often exposed to product performance claims that seem too good to be true & to new design concepts that work great in other climates or applications. While we want to make sure our designs take advantage of the best available technologies, we don't want to be scammed for adopt inappropriate technologies. A good understanding of building science is needed to get past the hype and find the truth.
MBEC has assembled a Building Science Professionals panel that will help you resolve whether an idea is good or too good to be true. Panel members are prepared to clarify some issues that they are frequently asked about, including:
- radiant barriers provide amazing energy benefits
- spray foam needs a vapour barrier
- closed cell foam is better than open cell
- you don't need to be concerned about radon in a home with a well sealed basement
- exterior insulation retrofits over wood frame construction will rot the sheathing
- thermal massing of structure is better than super insulation of envelope
- the cost of energy is an important influence on the design of a Net Zero Energy House
- why passive solar energy is often NOT cost-effective
- thermal mass provides significant energy benefits in all climates
- air barrier placement in wall assemblies doesn't matter
- should you / how do you ventilate a heated crawlspace
- the "safest" way to reduce heat loss through a stone foundation where one is not able to insulate on the exterior
- ground source heat pumps are always the green choice
- radiant panel heating systems always reduce heat energy use
- amish made boxes with heat lamps are a cheap way to heat your house
- furnace manufacturers, threatened by the potential of the friction furnace, stifled it just like Big energy did the Holmes carburetor (100 mpg from a 1949 Ford V8)
- vapour permeable vs. non vapour permeable air barriers
- insulation on interior vs. exterior of structure
- use of low permeance materials on exterior (extruded polystyrene/OSB) when you have an interior vapour barrier (isn't that creating a double vapour barrier?)
- more ventilation in your attic (or cathedral ceiling) is the best way to manage moisture
Myths
- at what depth is foam insulation not economically viable
- high performance buildings are better (i.e., healthier and more energy efficient) than heritage buildings
- cavity walls dry out once they get wet
- the MB Hydro Building - is it "green" to save costs or "green" at any cost?
- is fiberglass batt insulation an air barrier? Is that black stuff on fiberglass batt insulation mould?
Which is Better
- insulation types
- geothermal or wind
- polyiso cavity wall insulation - tape the joints or don't tape
- leed system of a more scientific approach like "BEES" (sp??)
Other Topics of Interest
- doors
- net zero buildings in Winnipeg's climate
- I would like the whole green approach examined
Hay bale houses
- currently, what is the most "green A/V barrier"?
- vacuum insulation materials
There is not enough time in one MBEC seminar period to speak of all the above topics, so we expect this to be an on-going series. Your feedback will influence the order in which issues are addressed.
Panel Board:
Mr. Ryan Dalgleish, Building Professionals
Mr. Bert Phillips, UNIES Limited
Mr. John Hockman, J.L. Hockman Consulting Inc.
Mr. Gary Proskiw, Proskiw Engineering Limited

Manitoba Building Envelope Council |
|
The Manitoba Building Envelope Council (MBEC) is a non-profit organization that began in 1986. MBEC is an association that has a diverse and wide cross section of members involved in the building envelope industry. Members consist of architects, engineers, manufacturers, consultants, educators, contractors, building owners and others related to this field. MBEC’s number one priority is to promote excellence in the building envelope through technology transfer. Education and learning is a life long journey for all of us. As technologies, building materials and building practices are changing at an increased pace, we need to ensure we have the knowledge and technical expertise to properly design and construct buildings that are durable, energy efficient, comfortable and safe. MBEC is managed by a volunteer Board of Directors and Executive Committee and does not have any paid employees. The members of MBEC donate their time and expertise to assist in the endeavors of the association. MBEC has formed links with various Building Envelope Councils across Canada and organizations such as Canada Mortgage and Housing Corporation, National Research Council and the Canadian Construction Research Board. The object of MBEC is to “promote the pursuit of excellence in the design, construction and performance of the building envelope”. |
