Local Policy and Market Changes
Significant Changes being made to the Ontario Building Code
that are allowing Renewable Energy to be a Cost Effective
Solution at the Design
Municipalities Identifying the need to include requirements for
New Construction beyond those in the Building Code
Incentives being offered to include Renewable Energy in new
Construction (New Directive given to Ontario Power Authority
for Unconstructed Buildings)
Design Professionals beginning to have an opportunity to work
with and implement Renewable Energy
Trades Workers now specializing in skills needed for Renewable
Energy install

Technology Changes
New Technologies are breaking down Barriers that Existed
Micro Inverters
Improved Controls
Energy Storage

16. Page 16
Barriers Existing
Trade Codes are Normally Slow to Adapt to the new
Technologies – Increased Communication with Inspectors for
Innovative Projects
Coordination with Local Utilities
Education from the Building Owner to the Hardware Supplier to
the Designer to the Installer (Dependent on Local Environment)
Certification of Hardware not International
Initial Costs for System and current Utility Costs
Confidence in Reliability

17. Page 17
Energy Conservation
Change the Conversation to Energy Conservation
Ownership of buildings change from the construction to operation phase
and so incentives must be at the front end
Integration with Local Utilities will present many barriers on project timing
Difficult to include all the emerging technologies under a single set of
rules (OPA FIT Program) and limit innovation
Energy conservation is easier on a political level to have support for
Reduced loads seen by the utilities will keep costs for new infrastructure
in control
