2 - indicates a criterion of normal importance; and
1 - indicates a minor criterion.
The points earned for each criterion are the product of multiplying
the SCORE times the MULTIPLIER. The MAXIMUM POINTS POSSIBLE in each
chart are added together and the POINTS EARNED are added to get
TOTALS. By dividing the TOTAL POINTS EARNED by the TOTAL MAXIMUM
POINTS POSSIBLE, the PERCENTAGE EARNED is determined. The
PERCENTAGE EARNED must be at least the minimum percentage specified
for that ACTIVITY category.

ORDINANCE NO. 31, 1991
OF THE COUNCIL OF THE CITY OF FORT COLLINS
AMENDING SECTION 29-526 (LAND DEVELOPMENT
GUIDANCE SYSTEM) OF THE CODE OF THE CITY
OF FORT COLLINS RELATING TO ENERGY
CONSERVATION METHODS
WHEREAS, the Council of the City of Fort Collins has determined that energy
conserving methods and measures in non-residential planned unit developments
should be encouraged; and
WHEREAS, the Council has determined that it is in the best interest of the
City that clear, detailed and specific standards be established for evaluating
energy conservation methods and awarding energy conservation points for non-
residential planned unit developments.
NOW, THEREFORE, BE IT ORDAINED BY THE COUNCIL OF THE CITY OF FORT COLLINS
that Section 29-526 of the Code of the City be amended as follows:
Section 1 . That Section 29-526(C) (3) (b) of the Code of the City of Fort
Collins is hereby amended to read as follows:
Lettered Criteria. The development plan is evaluated against each
of the applicable lettered criteria and assigned a SCORE. A
criterion is considered to be applicable if it is reasonably capable
of being applied to the development. Several criteria are
applicable to any development proposal and have been pre-checked
on the relevant chart. The numerical SCORE is assigned based upon
the following:
YES (+1) = for an adequate job of implementing
the criterion;
VERY WELL (+2) = for an excellent job of implementing
the criterion or for doing the best
job possible, given the constraints
and opportunities of the site; and
NO (0) = for no effort or failure to implement
the criterion.
A separate calculation shall be used to determine the appropriate
number of points to be awarded for the Energy Conservation
Criterion. This calculation shall be based upon either of the two
Energy Conservation Methods, as specified in Appendix G. Points
awarded for the Energy Conservation Criterion range from 0-4 points.
Each lettered criterion has been preassigned a MULTIPLIER which
determines the relative importance of that criterion to the other
criteria. The meaning of each MULTIPLIER is as follows:
5 - indicates that the criterion is of exceptional
importance;
4 - indicates that the criterion is very important;
Section 5. That Section 29-526(G) (3) (a) [4] [g] of the Code of the City of
Fort Collins is hereby repealed in its entirety and reenacted to read as
follows:
[g] Completed Energy Conservation Worksheet, using either Energy
Conservation Method One or Two, as described in Appendix G,
calculating the number of energy conservation points to be
awarded.
Section 6. That Section 29-526 of the Code of the City of Fort Collins
be amended by the addition of Appendix G, Energy Conservation Methods and
Worksheet, to read as follows:
APPENDIX G
ENERGY CONSERVATION METHODS
METHOD ONE: (Direct comparison to Model Energy Code. ) This method awards
points based on the extent to which the proposed building exceeds the minimum
standard as established in the Model Energy Code using the systems approach.
Certification by a professional engineer, licensed in Colorado, will be required
to demonstrate that the annual energy consumption will be a certain percentage
less than the same building just meeting the minimum standard as defined in the
Model Energy Code.
15 - 25% less (than Model Energy Code minimum) 1 .0 point
26 - 35% 2.0 points
36 - 45% 3.0 points
46% or more 4.0 points
METHOD TWO: Points will be given for the implementation of one or more of the
energy conservation measures listed below. The use of Method Two requires that
the final approved PUD plans and the construction plans submitted for a Building
Permit, must specify all of the energy conservation measures for which points
have been awarded in the approved plan. The total number of energy conservation
points earned will be based upon the following table:
0.6 - 1 .5 1 point
