SB 2030 Overview


Architecture 2030Background and Mission

• 2030’s mission is to rapidly transform the built environment to a central part of the solution to the climate and energy crises

• Building industry consumes more energy than any other sector in the United States

• Buildings were responsible for 44.6% of U.S. CO2 emissions in 2010

• Fossil fuels supply 75% of building sector energy consumption

• Current goal: 70% reduction• Net zero in 2030


Sustainable Buildings 2030Goals

The B3 Sustainable Building 2030 (SB2030) Energy Standard is a progressive energy conservation program designed to significantly reduce the energy and carbon in Minnesota commercial, institutional and industrial buildings

SB2030 Energy Standards are required for all state‐bonded Minnesota buildings that have started schematic design after August 2009

Compared to representative buildings in existence in 2003, the reduction in carbon producing fuel used for building energy is:

New Renovations60% in 2010 30% in 201070% in 2015 35% in 201580% in 2020 40% in 202090% in 2025 45% in 2025100% in 2030 50% in 2030


Minnesota and Outcomes Based Requirements for Public Buildings

• Based on 2030 Challenge % reduction goals from typical 2003 building

• Required for 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

Key Observations

• Government funded projects have a higher success rate• Residential, Retail/Commercial, and Mixed Use projects have a lower success rate due to market costs

• Healthcare is difficult to meet the challenge due to regulatory and functional requirements

• Minnesota EDA• Reporting Period 2010‐2015• 58.1 Million GSF• 438 total projects • 16.7% of total GSF met 60% target• 14.6% of projects met 60% target• 1.5% of total GSF met 70% target• 16.9% of total GSF achieved less than 40% savings


B3 Sustainable Building Program

• SB2030• 47 Projects• Government funded• 94% of projects met 60% target• 62% of projects met 70% savings

• B3• 7600 Buildings• 315 Million GSF• Operating buildings• Identified 42% of buildings that are good candidates for improvement


Getting to 70‐80%


Three Distinct Challenges

Design a high efficiency building

Build a high efficiency building

Operate a high efficiency building


Getting to 70% and 80% Reduction

1. Optimize Building DesignArchitecture informing energy usage through use of form and function

2. Maximize EfficienciesEvaluate the full breadth and optimal mix of energy consuming components

3. Innovative TechnologiesTest the value of the latest technologies including on‐site renewables

4. Informed OperationInclude ongoing operations to track performance and give regular feedback

• EUI Goal based on 70% reduction from typical 2003 building

• Online modeling tool adjusts for

• Hours of use• Building type• Local weather• Unregulated loads


SB 2030 As‐Designed ToolDesign to Meet EUI Goal

• Design and modeling reviewed for compliance with EUI goal

• Starting in early 2017 modeling can be done with online tool

• Interventions at design are far less expensive than post construction


Conclusion


Conclusion

• 27% of Minnesota EDA projects achieving SB2030 goals• Current and emerging technologies are needed to meet 70‐80% reduction• Integrated design and early energy analysis are key to attaining 70‐80% or greater savings

• Continuum of energy analysis and monitoring is needed to effect long‐term energy reduction
