In the summer of 2007, the Governor’s Climate Change Advisory Group recommended that to reduce greenhouse gas emissions in buildings, a similar approach to the national Architecture 2030 should be adopted for Minnesota. Architecture 2030 outlines specific performance targets for energy use in buildings until 2030. Every five years, the total energy use in buildings is to be reduced starting in 2010 at 60% and ending in 2030 as a 100% reduction (net zero carbon). The benchmark for these reductions in the national program is the energy use of the average building in 2003 found in the federal CBECS database.
- 2010 - 60% reduction in carbon producing fuel used for building energy.
- 2015 - 70% reduction in carbon producing fuel used for building energy.
- 2020 - 80% reduction in carbon producing fuel used for building energy.
- 2025 - 90% reduction in carbon producing fuel used for building energy.
- 2030 - 100% reduction in carbon producing fuel used for building energy.
In the spring of 2008, the Minnesota Legislature passed a bill designating the Center for Sustainable Research at the University of Minnesota to develop a Minnesota program reflecting the goals of Architecture 2030. This program was named Sustainable Buildings 2030 (SB 2030). See legislation below:
S.F. No. 2706, 3rd Engrossment –
2007-2008th Legislative Session (2007-2008)
Subd. 9. Building performance standards; Sustainable Building 2030.
- The purpose of this subdivision is to establish cost-effective energy-efficiency performance standards for new and substantially reconstructed commercial, industrial, and institutional buildings that can significantly reduce carbon dioxide emissions by lowering energy use in new and substantially reconstructed buildings. For the purposes of this subdivision, the establishment of these standards may be referred to as Sustainable Building 2030.
- The commissioner shall contract with the Center for Sustainable Building Research at the University of Minnesota to coordinate development and implementation of energy-efficiency performance standards, strategic planning, research, data analysis, technology transfer, training, and other activities related to the purpose of Sustainable Building 2030. The commissioner and the Center for Sustainable Building Research shall, in consultation with utilities, builders, developers, building operators, and experts in building design and technology, develop a Sustainable Building 2030 implementation plan that must address, at a minimum, the following issues:
- training architects to incorporate the performance standards in building design;
- incorporating the performance standards in utility conservation improvement programs; and
- developing procedures for ongoing monitoring of energy use in buildings that have adopted the performance standards.
The plan must be submitted to the chairs and ranking minority members of the senate and house of representatives committees with primary jurisdiction over energy policy by July 1, 2009.
Sustainable Building 2030 energy-efficiency performance standards must be firm, quantitative measures of total building energy use and associated carbon dioxide emissions per square foot for different building types and uses, that allow for accurate determinations of a building's conformance with a performance standard. The energy-efficiency performance standards must be updated every three or five years to incorporate all cost-effective measures. The performance standards must reflect the reductions in carbon dioxide emissions per square foot resulting from actions taken by utilities to comply with the renewable energy standards in section 216B.1691. The performance standards should be designed to achieve reductions equivalent to the following reduction schedule, measured against energy consumption by an average building in each applicable building sector in 2003: (1) 60 percent in 2010; (2) 70 percent in 2015; (3) 80 percent in 2020; and (4) 90 percent in 2025. A performance standard must not be established or increased absent a conclusive engineering analysis that it is cost-effective based upon established practices used in evaluating utility conservation improvement programs.
The annual amount of the contract with the Center for Sustainable Building Research is up to $500,000. The Center for Sustainable Building Research shall expend no more than $150,000 of this amount each year on administration, coordination, and oversight activities related to Sustainable Building 2030. The balance of contract funds must be spent for subcontracts with not-for-profit energy organizations, architecture and engineering firms, and other qualified entities to undertake technical projects and activities in support of Sustainable Building 2030. The primary work to be accomplished each year by qualified technical experts under subcontracts is the development and thorough justification of recommendations for specific energy-efficiency performance standards. Additional work may include:
- research, development, and demonstration of new energy-efficiency technologies and techniques suitable for commercial, industrial, and institutional buildings;
- analysis and evaluation of practices in building design, construction, commissioning and operations, and analysis and evaluation of energy use in the commercial, industrial, and institutional sectors;
- analysis and evaluation of the effectiveness and cost-effectiveness of Sustainable Building 2030 performance standards, conservation improvement programs, and building energy codes;
- development and delivery of training programs for architects, engineers, commissioning agents, technicians, contractors, equipment suppliers, developers, and others in the building industries; and
- analyze and evaluate the effect of building operations on energy use.
The commissioner shall require utilities to develop and implement conservation improvement programs that are expressly designed to achieve energy efficiency goals consistent with the Sustainable Building 2030 performance standards. These programs must include offerings of design assistance and modeling, financial incentives, and the verification of the proper installation of energy-efficient design components in new and substantially reconstructed buildings. A utility making an expenditure under its conservation improvement program that results in a building meeting the Sustainable Building 2030 performance standards may claim the energy savings toward its energy savings goal established in section 216B.241, subdivision 1c.
The commissioner shall report to the legislature every three years, beginning January 15, 2010, on the cost-effectiveness and progress of implementing the Sustainable Building 2030 performance standards and shall make recommendations on the need to continue the program as described in this section.

Renovations and SB 2030
As building renovations are often not as comprehensive in scope as the construction of new buildings the energy requirements new buildings would not be appropriate and not cost-effective for renovated buildings. As a result a reduced standard was created for renovated building, set at half of the required reduction from an average building as the new construction standard.
The resulting schedule, including percentage reductions for renovation project is as follows:
- 2009 - 2014: 60 percent better than an average building for new construction and 30% for renovation
- 2015 - 2019: 70 percent better than an average building for new construction and 35% for renovation
- 2020 - 2024: 80 percent better than an average building for new construction and 40% for renovation
- 2025 - 2029: 90 percent better than an average building for new construction and 45% for renovation
- 2030 and later: 100 percent better than an average building(net zero) for new construction and 50% for renovation
Projects with a combination of renovation and new construction will have their Energy Standard pro-rated based on the square footage of each project type.
The owners of a renovated building have the option of follow the new construction standard if they feel that the renovated standard is not appropriate for their building type or if they wish to pursue the more stringent standard.
