9-1-19-33R: POLICY 33 (RELATIVE) ENERGY CONSERVATION:
The goal of this policy is to incentivize energy conservation and renewable energy systems in new and existing development at a site plan level. This policy is not applicable to an application for a master plan. This policy seeks to reduce the community's carbon footprint and energy usage and to help protect the public health, safety and welfare.
A. Residential Structure Three (3) Stories or Less: For new construction, positive points will be awarded for the percentage of energy use reduction of the new residential structure compared to the same building built to the minimum standards of the town's most recently adopted residential provisions of the International Energy Conservation Code1 or the SSBC2, whichever code is the most restrictive As subsequent editions of the IECC and the SSBC are adopted by the town, the percent energy use reduction shall be compared to the baseline ERI score required established in that code.
For existing residential development, including additions, positive points will be awarded for the percentage of energy saved beyond the energy consumption analysis of the existing structure(s) as compared to the energy consumption of the proposed structure remodel.
Positive points will be awarded according to the following point schedule for new construction:
|
Points |
New Structures; Percent Energy Saved Beyond IECC and SSBC Standards2,Whichever Code Is The Most Restrictive |
|---|---|

Positive points will be awarded according to the following point schedule for structures that existed on July 14, 2020 which undergo major exterior remodels or additions:
|

Note:
3Existing HERS/ERI Index shall be for the structure prior to any modifications. Where an existing HERS/ERI score exceeds 125, a maximum score of 125 shall be assigned to the existing structure as a baseline to compare energy improvements to.
Commercial, Lodging and Multifamily in Excess of Three (3) Stories in Height: New and existing commercial, lodging, and multifamily developments are strongly encouraged to take advantage of the positive points that are available under this policy by achieving demonstrable and quantifiable energy use reduction within the development. For new construction, positive points will be awarded for the percentage of energy use reduction of the performance building when compared to the same building built to the minimum standards of the IECC or the SSBC, whichever code is the most restrictive. The percentage of energy use saved shall be expressed as MBh (thousand BTUs/hour).
For modifications to existing buildings including additions, positive points will be awarded for the percentage of energy saved beyond the energy consumption analysis of the existing structure(s) compared to the energy consumption of the proposed structure remodel. Points shall be awarded in accordance with the following point schedule:
|
Points |

Positive points will be awarded only if an energy analysis has been prepared by a registered design professional as required by subsection F1 of this section, using an approved simulation tool in accordance with simulated performance alternative provisions of the IECC or the SSBC, whichever code is the most restrictive.
B. Excessive Energy Usage: Developments with excessive energy components are discouraged. To encourage energy conservation, the following point schedule shall be utilized to evaluate how well a proposal meets this policy. Energy use from snowmelt, outdoor gas fireplaces, and outdoor heated pools/hot tubs is also regulated by the renewable energy mitigation program provisions of the building code.

If the planning commission determines that any of the following design features are required for the health, safety and welfare of the general public (e.g., heated sidewalk in a high-traffic pedestrian area), then no negative points shall be assessed. |
|

Up to 1,000 square feet of heated driveway, patio/deck, and walkway, etc. |
|

C. Other Design Features: 1 × (−4/+4) Other design features determined by the Planning Commission to conserve significant amounts of energy may be considered for positive points. Alternatively, other features that use excessive amounts of energy may be assigned negative points. However, positive points may not be assessed under this subsection if the project has been awarded positive points under subsection A or B of this section. Higher positive point awards will be given to larger scaled projects that conserve a significant amount of energy. Larger projects that consume large amounts of energy will be assessed more negative points.

E. Electrification: Positive four (+4) points may be awarded for new residential or commercial development that does not provide gas to the property and provides all of its energy and heating demands through electric or renewable energy sources, with a covenant recorded against the property in a form approved by the town attorney.
Positive four (+4) points may also be awarded to existing residential or commercial development that fully and permanently disconnect gas service to the property, with a covenant recorded against the property in a form approved by the town attorney.
Positive four (+4) points may be awarded where an addition to a residential or commercial property is proposed, where gas service is fully and permanently disconnected from any existing structures on the property and gas is not provided to the addition, with a covenant recorded against the property in a form approved by the town attorney.
A maximum of positive four (+4) points may be awarded under this subsection.
F. General Provisions:
1. A projected analysis shall be submitted at the time of development permit application if positive points are requested as well as submittal of a confirmed analysis prior to the issuance of a certificate of occupancy or certificate of completion. A HERS/ERI analysis shall be performed by a certified HERS/ERI rater. An analysis of energy saved beyond the IECC or the SSBC, whichever code is the most restrictive, shall be performed by the licensed Colorado engineer of record for the project.
2. No development approved with required positive points under this policy shall be modified to reduce the HERS/ERI index, percentage of improvement, or percentage of energy savings above the IECC standards in connection with the issuance of such development permit. ("Required positive points" means those points that were necessary for the project to be approved with a passing point analysis.)
3. Prior to the issuance of a certificate of occupancy each development for which positive points are awarded under this policy shall submit a letter of certification showing compliance with the projected energy rating or percentage of energy savings in comparison to the IECC or the SSBC, whichever code is the most restrictive. The required confirmed certification for a residential development three (3) stories or less in height shall be submitted by a certified HERS/ERI rater. The required confirmed certification for a residential development taller than three (3) stories, and for all commercial development, shall be submitted by a licensed Colorado engineer and accompanied by balance and commissioning reports.
