BACKGROUND
The Green Committee has met several times to develop recommendations and strategies to move
the City toward a greener, more sustainable future.
Developing an understanding of the programs and initiatives available to facilitate sustainable,
energy efficient, and environmentally friendly City building construction projects has been one of
the committee's goals.
ISSUE
Two options being used in Minnesota that are available to the City for the green construction of
future new buildings and building remodeling or expansion projects include Leadership in Energy
and Environmental Design (LEED) and Buildings, Benchmarks, and Beyond: the State of
Minnesota Sustainable Building Guidelines (B3- MSBG). The State has adopted the latter for all
bonded construction projects. Dakota County also references the State program for its new
construction.
LEED, a nationally recognized program, is a certification with increasing levels of performance. A
"LEED certified" classification is the first level, and by accumulating additional points a building
could receive Silver, Gold, and Platinum status. Categories within the LEED certification program
include: sustainable sites, water efficiency, energy and atmosphere, materials and resources, indoor
environmental quality, and innovation and design process. There are points that the
builder /developer can accumulate in each of these categories, with the total points determining what
level of certification the building receives.
There are additional costs above and beyond the increased construction cost to obtain certification
through the LEED program. These "soft costs" are design costs (0.4% 0.6 commissioning
(0.5% 1.5 documentation and fees (0.5% 0.9%), and energy modeling (0.1 for a total of
1.5% 3.1% of the project construction cost with an average of 2.3 These types of costs can
range from a low of $.40 /square foot up to $1.00 /square foot of the total construction cost.
B3 -MSBG is a State program with many categories similar to LEED. The categories are:
performance management, site and water guidelines, energy and atmosphere, materials and waste
guidelines, indoor environmental quality guidelines, and candidates for innovation credits. Unlike
LEED, there is no formal certification. In other words there is no formal application process and no
documentation on achieving the specifics of the program. B3 -MSBG designed and constructed
projects are designated compliant as opposed to going through a 3` party review process to become
certified. The program does have required guidelines that must be conformed to in each category as
well as recommended guidelines which will increase a project's performance. The "soft costs" are
less with this program than the LEED program and include design and documentation expenses.
SUMMARY
In staff's opinion, the energy, environmental, and economic benefits are similar between LEED and
B3 -MSBG. The LEED advantage is that it is nationally recognized and architects and designers are
becoming more familiar with the program's requirements. In a side -by -side comparison of B3-
MSBG to LEED, fulfilling all the required guidelines for the B3 -MSBG would result in a LEED
certified building. If all of the required and recommended guidelines were achieved, the building
would be consistent with a LEED Platinum building.
Given that the benefits associated with the B3 -MSBG program are similar to the LEED program
with less soft costs, staff would support adopting the B3 -MSBG voluntary program for new
construction and substantial reconstruction projects within the City. While LEED may be more well
known nationally, the benefits of obtaining the certification may not be as beneficial in the public
sector as in the private sector. Private sector companies are beginning to market their properties for
rent, enticing businesses because the building is LEED certified. The City doesn't need to have that
moniker on the public buildings because the use of the buildings is different. Promoting the green
construction of the public building using the B3 -MSBG system should be adequate for publicity to
illustrate the Council's dedication to the Greening Initiative.
