November 9, 2009 – Vol.14 No.34 Rocky Mountain Institute (RMI) Releases “Green Footstep” Online Carbon Calculator for Green Buildings. While many carbon calculators are available online, none address multiple building emissions over the building lifetime. “Green Footstep makes it easier for design professionals to set the design targets they’ll need to achieve a carbon neutrality that includes not just operation, but also embodied carbon and others,” said Victor Olgyay, AIA, principal at RMI. “Just as a life cycle cost analysis of a green building design shows the operating costs you are saving over time, Green Footstep shows you the saved carbon.” Green Footstep also shows designers how to comply with specific design goals such as LEED’s energy credits and the 2030 Challenge, the organization that has challenged designers to make all new buildings carbon neutral by 2030. Edward Mazria , founder and executive director of Architecture 2030,says, “Rocky Mountain Institute's Green Footstep is an extremely valuable goal-setting and evaluation tool that will help building designers assess a project's carbon emission impacts with regard to site, construction, and operations. Because the 2030 Challenge is integrated into the program, this tool can also help designers in their efforts to meet or exceed the 2030 Challenge targets.” Michael Bendewald, an analyst with RMI who developed the online version, called Green Footstep a “designer’s tool” that designers can use to make specific design decisions that reduce carbon emissions on residential and commercial new and retrofit building construction projects, from pre-design through occupancy.
It’s also an educational tool that helps users understand a building’s life cycle carbon footprint. “Since we all have bank accounts, allow me to use an accounting metaphor to explain Green Footstep's way of showing a project's carbon emissions,” Bendewald explains. ”The native-state carbon storage of a site, including such things as standing timber and other vegetation that existed before development, is the amount of carbon the owner of the facility ‘owns.’ Any carbon emissions send the owner into a ‘carbon debt.’ In order for a project to be ‘carbon neutral,’ this debt must be paid off and the original amount of carbon – equal in magnitude to the native-state carbon storage – must be restored. Green Footstep allows designers to adjust design targets, such as building energy use intensity and incorporating more renewables, that will get the building out of the carbon debt, edging the building closer to carbon neutrality.” Green Footstep’s website provides case studies so users can explore how Green Footstep has allowed past projects to reach their carbon reduction goals. Users can also create a login that allows them to save and reload their own projects as they work on them. (11/3/09)
