The 2030 Challenge
Q. What is the baseline for the 2030 Challenge?
A. On May 4, 2007 the American Institute of Architects (AIA), the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), Architecture 2030, the Illuminating Engineering Society of North America (IESNA), and the U.S. Green Building Council (USGBC), supported by representatives of the U.S. Department of Energy, agreed to define the baseline starting point for their common target goals as the national average/median energy consumption of existing U.S. commercial buildings as reported by the 2003 Commercial Building Energy Consumption Survey (CBECS). CBECS data is a set of whole-building energy use measurements gathered by the DOE’s Energy Information Administration, which can be used to determine a national energy use intensity using kBtu/sq. ft.-yr as the metric.
See Press Release.
Q. What is the metric for the 2030 Challenge?
A. The metric for the 2030 Challenge is site Energy Use Intensity (EUI) in kBtu/sq. ft.-yr, not source EUI.
Q. Are the 2030 Challenge targets for the year I start design or for the year the design of the project is expected to be completed?
A. The 2030 Challenge targets are for the year of the project’s completion of design, not the year that the project begins initial design.
Q. Does the 2030 Challenge call for all new building and major renovations to be "net-zero energy" building by 2030?
A. No, the 2030 Challenge advocates for “carbon-neutral” buildings in 2030, which is not to be confused with “net-zero energy” buildings. A carbon-neutral building is defined to be a building that uses no fossil fuel, greenhouse-gas-emitting energy to operate. In contrast a net-zero energy building must produce as much energy on site as it consumes.
Q. Can I just buy renewable energy for my project and meet the 2030 Challenge?
A. No, Architecture 2030 advocates that the 2030 Challenge energy reductions be met firstly through energy-efficient design strategies. These are low-cost and/or no-cost options, which include proper orientation, daylighting and passive heating and cooling strategies, etc. Secondly, Architecture 2030 recommends applying energy-efficient technologies and systems, which include high-efficiency mechanical equipment and on-site renewable energy generation. Once all energy-efficient design strategies and technologies are exhausted, Architecture 2030 recommends purchasing off-site renewable energy and/or renewable energy credits for the project’s remaining energy needs (20% maximum).
Q. The 2030 Challenge allows for 20% maximum of off-site renewable energy and/or renewable energy credits. 20% of what?
A. The 2030 Challenge allows for 20% of the required reduction to come from purchasing renewable energy and/or certified renewable energy credits. [This is also a major difference from a net-zero energy building.] Presently, the Challenge allows for 20% of the 60% reduction, but as the Challenge progresses it will be 20% of the 70% reduction, or 20% of the 80% reduction, and so on. The rest of the reduction should be gained firstly through energy-efficient design and secondly through on-site technology (including on-site renewable energy).
Architecture 2030 does not discourage using utility renewable energy and/or renewable energy credits for the rest of the project's power; however, only 20% of the reduction can be counted towards meeting the 2030 Challenge targets.
Q. Of the 20% maximum allowed, which types of renewable energy and/or certified renewable energy credits qualify for purchase?
A. We recommend consulting the Green-e Climate Protocol for Renewable Energy for determining the types of acceptable renewable energy purchases.
Q. Is there a tool I can use to see if my project is meeting the 2030 Challenge?
A. Yes, The Environmental Protection Agency (EPA) has available an online tool, Target Finder, that enables users to determine the average energy consumption of specific building types in a specific region, as well as to determine energy reduction targets in accordance with the 2030 Challenge. Target Finder should be the first resource in determining a projects energy consumption target. Architecture 2030 recommends not inputting information into Section 4, Estimated Design Energy when determining your energy consumption target, to ensure a baseline that is an average building with an average fuel mix.
Q. What if my project’s building type is not available in Target Finder?
A. If a project’s building type is not available in Target Finder:
