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

Permit Applications

• Construction– Renovations, Additions

• Non Construction – Change of Use, Occupancy

VBBL– Existing Buildings

14

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
