Integrating Renewable Energy Systems

  1. 1. Engineering Our Sustainable Future Sustainable Building Advisor Renewable Energy Integration August 17th, 2013 Evergreen Brick Works, Toronto, ON Presented by Livio Nichilo P.Eng
  2. 2. Page 2 Presentation Overview • Integrated Design Process (Loads and Energy Sources) • Market Trends • Renewable Energy Systems • Evaluation for Building Integration Break Time (Start time at 10:30 pm for 15 minutes) • Current Barriers for Implantation • Energy Conservation - Net Metering and Energy Storage • Project Case Study

  14. 14. Page 14 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
  15. 15. Page 15 Technology Changes New Technologies are breaking down Barriers that Existed Micro Inverters Improved Controls Energy Storage
  16. 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. 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 Greenhouse Gas carbon markets – New financial mechinisms
