Learning Objectives What is the Maine Advanced Buildings program? What is Core Performance? How do Core Performance and Maine Advanced Buildings relate to LEED? How do I take my project through Maine Advanced Buildings?
Maine Advanced Buildings • Incentive program for new commercial construction projects • Based on Core Performance Guidelines • Primarily for office, education and public assembly, other building types will be considered • 10,000 s.f. – 70,000 s.f. • Incentive of $1.00/s.f. • Efficiency Maine must be involved during design process
What is Advanced Buildings:Core Performance Core Performance, is a multi-path, flexible program to achieve predictable energy savings in commercial buildings
Why? • What need does Core Performance meet? • What Role does Core Performance play?
Energy use and cost There is an increasing demand for a limited resource. Volatile and rising energy costs means we need to reduce our consumption.
Environmental Impact of Commercial and Residential Buildings • 71% of total U.S. electricity consumption • 40% of total U.S. primary energy • 39% of total U.S. CO2 emissions • 30% of all raw material • 30% of the waste stream • 12% of water use
National Focus on Change • AIA - 50% reduction in fossil fuel use in buildings by 2010; subsequent 10% every 5 year improvement • ASHRAE - Collaborating on design guidelines for 50% energy savings, with IESNA, AIA, USGBC • USGBC - LEED has increased the energy performance prerequisite • NBI – 50% by2010 goal

Energy Performance Baselines Think of Core Performance as a Vehicle, Not a Destination • 25% to 40% better than ASHRAE 90.1 – 2001 • 20% to 35% better than ASHRAE 90.1 -2004 • Equivalent to an EPA Energy Star rating of 90 +
Effectiveness is Widely Recognized • Prescriptive path to LEED-NC 2.2 and LEED 2009 credit Ea 1.1 • Adopted By: • Efficiency Maine • Energy Center of Wisconsin • We Energies • Mass Stretch Code • Energy New Brunswick • National Grid • NSTAR • WMECO • CLC and Keyspan • Efficiency Vermont
Direct AB Core Energy Benefits • Reduced First Cost for Energy Systems • Reduced Operating and Maintenance Expense • Reduced Exposure to Energy Price Volatility
Indirect AB Core Energy Benefits • Energy savings increase ROI which increases building market value • Faster lease-up at competitive rates • Increased productivity/reduced absenteeism • Improved occupant satisfaction and retention
AB Core Risk Management Benefits • Construction timelines and budgets tend to have fewer changes due to careful planning process • Acceptance testing provides documented performance and reliability assurance to owners and occupants • Life cycle planning reduces the likelihood of early obsolescence (“future-proofing”)

Program Adminstration • Screening form • Initial design review • Application • Construction • Close-out, owner training • Project Completion • Incentive Payout
Program Administration • EMaine reviews drawings and specs for eligibility • Application is submitted and design review for program acceptance begins • Emaine visits site as scheduled to observe related installations (insulation, commissioning, etc.) • Where ever possible Emaine will fill out the paperwork!
