CCBFC - Climbable Guards
CCBFC deferred decision in February
Executive Committee commissioned a study to:
• to determine whether there is sufficient data
to support the claim that the artistic guard design is the cause of,
or a contributing factor in, incidents of injury or death of children as
a result of the children climbing the guards;
• results due end of June
Interim Change to clarify provision
• Clarify that any clause complies - “or”
• Add appendix information to describe why
requirements make guards less climbable

JTG Energy Efficiency
HSB Approach
•
•
•
•
Reflect regional construction practice
Simple payback and life cycle costing
Reflect different energy sources
Differences by Occupancy
Executive Direction
•
•
Follow NECB approach
Regional construction practice
•
•
•
Cost methodology
•
•
•
•
•
is the normal course of action in code development
will be taken care of by flexible framework and provincial adoption
is only one criterion to describe the impact of the change
Neither NECB nor EEHSB will use LLC
Focus on energy target (near ERS 80)
Req’s should stay energy source neutral
Differences by occupancy type
•
•
Differences between small bldgs and housing expected
Small buildings will follow NECB
6
JTG Energy Efficiency
Benchmark Study
• Determine Baseline (current construction practice and current
level of performance)
• Study was delayed
• Contract awarded last week
Sub-task Groups
