B3/SB 2030 PROGRAMS AND TOOLS

PREDESIGN DESIGN CONSTRUCTION OPERATIONS

Establish project-specific performance requirements.

Refine project-specific performance requirements.

Optimize use of resources to achieve performance requirements.

Evaluate success of design strategies through early and repeated modeling.

Implement construction practices that meet performance requirements.

Ensure project is meeting performance requirements.

5

Holistic set of sustainable building guidelines to be used from pre-design through the life of the building6

Progressive building energy conservation program that aligns with Architecture 2030 targets 7

SUSTAINABLE BUILDING 2030

REQUIRED PROJECTSSB 2030 is a required program for all state-bonded buildings that receive General Obligation (GO) bonds (regardless of the amount):• All new buildings• All substantially renovated buildings that include:

– At least 10,000 sf

– Replacement of HVAC system in all or part of the building

• That started Schematic Design after August 1, 2009

8

SUSTAINABLE BUILDING 2030

REQUIREMENTMeet energy performance targets (Energy Standards) that reduce* the use of carbon producing fuel for building operations by:

• 60% (for buildings designed) in 2010• 70% in 2015• 80% in 2020• 90% in 2025• 100% in 2030

These targets are halved for renovations of existing buildings.

*from a baseline of representative buildings in existence in 2003.

OPPORTUNITIES FOR GROWTH

Climate Solutions and Economic Opportunities• Expanding SB 2030 to all buildings was one of the top

strategies – Achieves nearly 20% of emissions reduction required to

meet Minnesota’s 2030 target– Creates over 2,500 new jobs annually

Minnesota’s 2025 Energy Action Plan• Adopt SB 2030 as a stretch code that can be adopted by

local jurisdictions• Increase adoption of commercial building energy

benchmarking and disclosure programs• Improve building operations to capture energy efficiency

opportunities
