Technical Research Committee

Meeting Summary May 28 & 29, 2009 

 

A number of critical issues were raised at the May meetings that will relate to Saskatchewan builders and renovators.

Green Building Documents

CHBA in conjunction with CMHC are developing a number of publications for builders and renovators to help guide them and their customers through green projects. CHBA has developed a Homeowner’s Guide to Green Renovation that will be available to member renovators electronically. This 8 page document guides consumers through 3 steps to "green" their renovation plan:

-

 

Increasing energy and water efficiency

-

 

Ensuring clean indoor air

-

 

Choosing resource smart materials and products

The guide provides multiple hits and suggestions of areas to explore with the homeowners renovation contractor. The customizable product will allow for the inclusion of the contractor’s logo and contact info and can be printed in a simple black and white form or in a professional color bound product depending on the contractor’s needs. The document should be available to contractors in the summer.

CHBA is also looking to develop generic info sheets on green options for renovators and builders to assist in the integration of these options into projects and to educate consumers on potential savings, costs and risks. In conjunction with this effort a larger technical guide geared to renovator similar to the Guide to New Homes available to new home builders will be developed.

Radon

Health Canada’s promotional campaign to highlight the new acceptable Radon levels did not go forward this fall, likely due to the industry’s inability to handle the demand for testing and remediation. However, the CHBA has advised that the public has the expectation that their "professional" builder or renovator should be aware of the radon risks and have a duty to advise homeowners on the issue. A document will be released soon which will provide a framework regarding changes to contracts and documentation to remove potential liability in this area

.Stucco Failures in Alberta

Alberta has seen a number of water penetration issues relating to stucco applications, many of which are receiving a lot of exposure in the local media. While the exact causes are still being investigated, it looks like the primary issue is the incorrect application of acrylic stucco without a proper external insulated finishing system. The resulting failure of the building envelope is resulting in significant mould growth and considerable mediation expenses. It is advised that builders and renovators inspect their building envelopes to ensure the proper use of EIFS and stucco application.

Building Envelope Inspections

CHBA Alberta expects to receive a report from the province that will call for mandatory building envelope inspections similar to those required in BC. Further details are not available at this time.

Waste Diversion

The Canadian Council of Ministers of the Environment (CCME) is seeking to develop a Canada-wide Action Plan for External Producer Responsibility (EPR). In essence the proposal would make producers responsible for the recycling, re-use, or disposal of products they have sold, similar in effect to the deposit return system for beverage containers in many jurisdictions. Initial activities would focus on packaging and electronics in an effort to increase recycling and reduce the amount of materials sent to land fills. A longer term (2012-2014) target will be the construction industry. The reduction of land fill waste and increased recycling is a priority across the country. TRC is closely monitoring a program being launched in Alberta in 2010, however this should be a priority for Home Builders’ Associations across the country.

Fire Research in New Homes

The National Research Council conducts ongoing research looking at fire risk and performance of new home construction. Valuable information relating to fire performance of wall and floor systems, structural components and detection and suppression systems can be found at http://irc.nrc-cnrc.gc.ca/fr/research_e.html. The site also provides some interesting research on the importance of closing doors in homes and other occupant behaviours that affect fire ignition and spread as well the affect of furnishings in the home with respect to fire growth.

2015 National Building Code – Smoke Detectors

The committee developing Part 9 of the 2010 NBC voted in favour of a requirement to include smoke detectors in all bedrooms in addition to hallways on any floor with bedrooms attached. CHBA argued against the requirement citing the falling death rate from fires and the relative safety of new houses. However, recent research has shown that seniors and teenagers are less likely to hear fire alarms behind closed doors

. Spray Foam Insulation & Roof Ventilation

There seems to be confusion regarding the code requirement for an air gap against the roof sheathing when applying spray foam insulation. It is recommended that builders and renovators check with their local building officials to determine appropriate application prior to applying spray foam insulation to roofs
