VBBL– Existing Buildings Principles for Existing Building Policy • Progressive upgrade requirements – Rapid paybacks (2 -3 years) • Gather data – Build database of Energy Utilization Intensities • Align renovations to existing programs

VBBL– Existing Buildings Permit Applications • Construction – Renovations, Additions • Non Construction – Change of Use, Occupancy

VBBL– Existing Buildings Permit Applications • Existing Triggers – Life Safety, Accessibility, Structural • New Trigger – Environmental Protection: • Disclosure of Energy Use (Portfolio Manager) • Energy Assessment (or BOMA Equivalent) • Menu of Construction Options

VBBL– Existing Buildings Requirements based on type of upgrade

Vancouver Building By-law: Next Steps • Spring 2012 – Complete Industry & Public Consultations – Finalize By-law language based on consultations • Fall 2012 – Internal staff training – Industry workshops (including CP Update Workshop) • Spring 2013 – Ongoing training/support to staff and industry during adoption period and beyond
